    Full Text Available Binkley and Johnson first reported this syndrome in 1951. But it was in 1960, Gorlin-Goltz established the association of basal cell epithelioma, jaw cyst and bifid ribs, a combination which is now frequently known as Gorlin-Goltz syndrome as well as Nevoid Basal Cell Carcinoma Syndrome (NBCCS. NBCCS is inherited as an autosomal dominant trait with high penetrance and variable expressivity. NBCCS is characterized by variety of cutaneous, dental, osseous, opthalmic, neurologic and sexual abnormalities. One such case of Gorlin-Goltz syndrome is reported here with good illustrations.

    Nevoid basal cell carcinoma syndrome, or basal cell nevus syndrome (Gorlin syndrome), is a rare autosomal dominantly inherited disorder that is characterized by development of basal cell carcinomas from a young age. Other distinguishing clinical features are seen in a majority of patients, and include keratocystic odontogenic tumors (formerly odontogenic keratocysts) as well as dyskeratotic palmar and plantar pitting. A range of skeletal and other developmental abnormalities are also often seen. The disorder is caused by defects in hedgehog signaling which result in constitutive pathway activity and tumor cell proliferation. As sporadic basal cell carcinomas also commonly harbor hedgehog pathway aberrations, therapeutic agents targeting key signaling constituents have been developed and tested against advanced sporadically occurring tumors or syndromic disease, leading in 2013 to FDA approval of the first hedgehog pathway-targeted small molecule, vismodegib. The elucidation of the molecular pathogenesis of nevoid basal cell carcinoma syndrome has resulted in further understanding of the most common human malignancy.

    Full Text Available Gorlin-Goltz syndrome or basal cell nevus syndrome is an autosomal dominant syndrome characterized by skeletal anomalies, numerous cysts observed in the jaw, and multiple basal cell carcinoma of the skin, which may be accompanied by falx cerebri calcification. Basal cell carcinoma is the most commonly skin tumor with slow clinical course and low metastatic potential. Its concomitance with Gorlin syndrome, resulting from a mutation in a tumor suppressor gene, may substantially change morbidity and mortality. A 66-year-old male patient with a history of recurrent basal cell carcinoma was presented with exophthalmus in the left eye and the lesions localized in the left lateral orbita and left zygomatic area. His physical examination revealed hearing loss, gapped teeth, highly arched palate, and frontal prominence. Left orbital mass, cystic masses at frontal and ethmoidal sinuses, and multiple pulmonary nodules were detected at CT scans. Basal cell carcinoma was diagnosed from biopsy of ethmoid sinus. Based on the clinical and typical radiological characteristics (falx cerebri calcification, bifid costa, and odontogenic cysts, the patient was diagnosed with metastatic skin basal cell carcinoma accompanied by Gorlin syndrome. Our case is a basal cell carcinoma with aggressive course accompanying a rarely seen syndrome.

    Full Text Available Abstract Nevoid basal cell carcinoma syndrome (NBCCS, also known as Gorlin syndrome, is a hereditary condition characterized by a wide range of developmental abnormalities and a predisposition to neoplasms. The estimated prevalence varies from 1/57,000 to 1/256,000, with a male-to-female ratio of 1:1. Main clinical manifestations include multiple basal cell carcinomas (BCCs, odontogenic keratocysts of the jaws, hyperkeratosis of palms and soles, skeletal abnormalities, intracranial ectopic calcifications, and facial dysmorphism (macrocephaly, cleft lip/palate and severe eye anomalies. Intellectual deficit is present in up to 5% of cases. BCCs (varying clinically from flesh-colored papules to ulcerating plaques and in diameter from 1 to 10 mm are most commonly located on the face, back and chest. The number of BBCs varies from a few to several thousand. Recurrent jaw cysts occur in 90% of patients. Skeletal abnormalities (affecting the shape of the ribs, vertebral column bones, and the skull are frequent. Ocular, genitourinary and cardiovascular disorders may occur. About 5–10% of NBCCS patients develop the brain malignancy medulloblastoma, which may be a potential cause of early death. NBCCS is caused by mutations in the PTCH1 gene and is transmitted as an autosomal dominant trait with complete penetrance and variable expressivity. Clinical diagnosis relies on specific criteria. Gene mutation analysis confirms the diagnosis. Genetic counseling is mandatory. Antenatal diagnosis is feasible by means of ultrasound scans and analysis of DNA extracted from fetal cells (obtained by amniocentesis or chorionic villus sampling. Main differential diagnoses include Bazex syndrome, trichoepithelioma papulosum multiplex and Torre's syndrome (Muir-Torre's syndrome. Management requires a multidisciplinary approach. Keratocysts are treated by surgical removal. Surgery for BBCs is indicated when the number of lesions is limited; other treatments include laser

    Full Text Available The Gorlin-Goltz syndrome, also known as nevoid basal cell carcinoma syndrome (NBCCS, is an infrequent multisystemic disease inherited in a dominant autosomal way, which shows a high level of penetrance and variable expressiveness. It is characterized by odontogenic keratocysts in the jaw, multiple basal cell nevi carcinomas and skeletal abnormalities. This syndrome may be diagnosed early by a dentist by routine radiographic exams in the first decade of life, since the odontogenic keratocysts are usually one of the first manifestations of the syndrome. This case report presents a patient diagnosed as NBCCS by clinical, radiographic and histological findings in a 13-year-old boy. This paper highlights the importance of early diagnosis of NBCCS which can help in preventive multidisciplinary approach to provide a better prognosis for the patient.

    Full Text Available Nevoid basal cell carcinoma syndrome (BCNS is an autosomal dominant inherited disorder. Multiple organ systems may be affected in this syndrome including abnormalities of the skin, skeletal system, genitourinary system and central nevus system. In this report, we present a case of Nevoid basal cell carcinoma syndrome in a 26-year-old male patient. The patient had multiple odontogenic keratocyst in the posterior of mandible, syndactyly in both hand and bifid rib. After enucleation and curettage, he was followed for two years. A number of both clinical and radiological criteria are used to diagnose this syndrome. Basal cell carcinoma syndrome is diagnosed with two major criteria or one major and two minor criteria. We must suspect this disorder in young patients with multiple odontogenic keratocyst and dental abnormalities whether related or not with other clinical manifestations or familial history.

    Basal cell carcinoma of the axilla, an area that is not usually exposed to the sun, is rare. Individuals with basal cell nevus syndrome, a disorder associated with a mutation in the patch 1 (PTCH1) gene, develop numerous basal cell carcinomas. To describe a woman with basal cell nevus syndrome who developed a pigmented basal cell carcinoma in each of her axilla and to review the features of axillary basal cell carcinoma patients with Goltz-Gorlin syndrome. Pubmed was used to search the following terms: axillary basal cell carcinoma and basal cell nevus syndrome. The papers and their citations were evaluated. Basal cell nevus syndrome patients with basal cell carcinoma of the axilla were observed in two women; this represents 2.5% (2 of 79) of the patients with axillary basal cell carcinoma. Both women had pigmented tumors that were histologically nonaggressive. The cancers did not recur after curettage or excision. Basal cell carcinoma of the axilla has only been described in 79 individuals; two of the patients were women with pigmented tumors who had basal cell nevus syndrome. Similar to other patients with axillary basal cell carcinoma, the tumors were histologically nonaggressive and did not recur following treatment. Whether PTCH1 gene mutation predisposes basal cell nevus patients to develop axillary basal cell carcinomas remains to be determined.

    Nevoid basal cell carcinoma syndrome (NBCCS) is rare in black persons. We describe an 11-year-old black boy with NBCCS who presented with exotropia and a painful, expanding, cystic mass in the left posterior alveolar ridge. Further examination revealed odontogenic keratocysts with palmar and plantar pitting. Less than 5% of reported patients with NBCCS are black. To our knowledge, this is the first report of a black patient with NBCCS presenting with exotropia and an impacted molar displaced into the orbit by an odontogenic keratocyst.

    Full Text Available Gorlin syndrome (Naevoid Basal Cell Carcinoma Syndrome is a rare autosomal dominant syndrome caused by mutations in the PTCH gene with a birth incidence of approximately 1 in 19,000. Patients develop multiple basal cell carcinomas of the skin frequently in early life and also have a predisposition to additional malignancies such as medulloblastoma. Gorlin Syndrome patients also have developmental defects such as bifid ribs and other complications such as jaw keratocysts. We studied the incidence and frequency of basal cell carcinomas in 202 Gorlin syndrome patients from 62 families and compared this to their gender and mutation type. Our data suggests that the incidence of basal cell carcinomas is equal between males and females and the mutation type cannot be used to predict disease burden.

    Nevoid basal cell carcinomas (NBCCs) are a prototype of a genetic form of basal cell carcinoma. These basal cell cancers, rather than being caused by genetic factors alone, are most likely the product of genetic and environmental factors. The NBCC syndrome provides a model for studying tumors induced by ionizing radiation and for viewing carcinogenesis as a multistage process explainable by a minimum of two steps. The interaction of genetic and environmental factors in producing tumors to which an individual is predisposed can be studied in patients with the NBCC syndrome and childhood medulloblastoma that was treated by radiation therapy. Individuals with the NBCC syndrome represent a special subgroup with a hereditary predisposition to basal cell carcinoma in whom ionizing radiation may supply the subsequent mutation necessary for tumor development. The genetically altered epidermis underlying the palm and sole pits found in patients with the syndrome represents basal cell carcinoma in situ from which basal cell carcinomas develop, albeit infrequently. The restrained biologic behavior of most of these tumors contrasts with the usual destructive behavior of the NBCCs of the head and neck in the same patient

    Gorlin-Goltz syndrome or nevoid basal cell carcinoma syndrome (NBCCS) comprises multiple basal cell carcinomas, keratocysts of the jaw, palmar/plantar pits, spine and rib anomalies, calcifications of the falx cerebri etc. The diagnosis is made according to clinical criteria (Kimonis Criteria) and genetic ones. We studied one family where father and then his sun resulted affected by each syndrome. Gorlin-Goltz syndrome is a rare disease diagnosed according to clinical criteria sometimes difficult to integrate. The family case we presented shows how you can get diagnosis even in older age and after numerous surgeries. Patients should be given special attention and therefore should be monitorized and need multidisciplinary treatments continued in time, even a trivial change of signs and symptoms may be an important indicator of a precipitating event which puts the patient's life under threat.

    A 35-year-old man presented with a rare case of nevoid basal cell carcinoma syndrome, or Gorlin's syndrome, associated with both medulloblastoma and meningioma, manifesting as visual field constriction due to multiple parasellar tumors. He had undergone resection of a medulloblastoma at the age of 1 year 9 months, followed by adjunctive irradiation with a total dose of 40 Gy. He presented with multiple subcutaneous nodules on his face and neck. Histological examination of biopsy specimens established the diagnosis of nevoid basal cell carcinoma syndrome. Tuberculum sellae meningioma was removed through a craniotomy, and his symptoms improved. Meningioma is known to occur in the field of therapeutic irradiation, so chemotherapy may be a better option for medulloblastoma associated with nevoid basal cell carcinoma syndrome. (author)

    Basal cell carcinoma (BCC) is the most common skin cancer worldwide with increasing incidence, but difficult to assess due to the current under registration practice. Despite the low mortality rate, BCC is a cause of great morbidity and an economic burden to health services. There are several risk factors that increase the risk of BCC and partly explain its incidence. Low-penetrance susceptibility alleles, as well as genetic alterations in signaling pathways, namely SHH pathway, also contribute to the carcinogenesis. BCC associate with several genetic syndromes, of which basal cell nevus syndrome is the most common.

    The uv-induced DNA repair synthesis in peripheral leukocytes from 7 patients with the nevoid basal cell carcinoma syndrome was compared to that in peripheral leukocytes from 5 patients with basal cell carcinomas and 39 healthy subjects. A dose response curve was established for each individual, and maximum DNA repair synthesis was used as a measure of the capacity for DNA repair. The patients with the nevoid basal cell carcinoma syndrome had about 25% lower level of maximum DNA repair synthesis as compared to the patients with basal cell carcinomas and control individuals. The possibility that DNA repair mechanisms may be involved in the etiology to the nevoid basal cell carcinoma syndrome is discussed

    Gorlin-Goltz (GS) syndrome is an autosomal dominant disease linked to a mutation in the PTCH gene. Major criteria include the onset of multiple basal cell carcinoma (BCC), keratocystic odontogenic tumours in the jaws and bifid ribs. Dermoscopy and reflectance confocal microscopy represent imaging tools that are able to increase the diagnostic accuracy of skin cancer in a totally noninvasive manner, without performing punch biopsies. Here we present a case of a young woman in whom the combined approach of dermoscopy and RCM led to the identification of multiple small inconspicuous lesions as BCC and thus to the diagnosis of GS syndrome. © 2016 The Australasian College of Dermatologists.

    Nevoid basal cell carcinoma syndrome (NBCCS), which is also known by other names, including Gorlin-Goltz syndrome and multiple basal-cell carcinoma (BCC) syndrome, is a rare multi-systemic disease inherited in a dominant autosomal manner with complete penetrance and variable expressivity. The main clinical manifestations include multiple BCCs, odontogenic keratocysts of the jaw, hyperkeratosis of the palms and soles, skeletal abnormalities, intracranial calcifications and facial deformities. A 31-year-old male diagnosed with Gorlin-Goltz syndrome with multiple unresectable facial BCCs was treated with the Hedgehog inhibitor vismodegib. After one month of therapy on vismodegib, there were significant reductions in the size of multiple BCCs on the patient's face. The patient remains on this therapy. Hedgehog pathway inhibition is an effective strategy to treat unresectable BCCs from Gorlin-Goltz syndrome. Although vismodegib shows some promising clinical results in the early phase of its use, there are concerns of possible resistance developing within months. Duration of therapy, role of maintenance treatment and drug modification to reduce resistance need to be explored in future case studies.

    Nevoid basal cell carcinoma syndrome (NBCC; Gorlin syndrome), an autosomal dominant disorder linked to 9q22.3-q31, and caused by mutations in PTC, the human homologue of the Drosophila patched gene, comprises multiple basal cell carcinomas, keratocysts of the jaw, palmar/plantar pits, spine and rib anomalies and calcification of the falx cerebri. We reviewed the findings on 105 affected individuals examined at the NIH since 1985. The data included 48 males and 57 females ranging in age from 4 months to 87 years. Eighty percent of whites (71/90) and 38% (5/13) of African-Americans had at least one basal cell carcinoma (BCC), with the first tumor occurring at a mean age of 23 (median 20) years and 21 (median 20) years, respectively. Excluding individuals exposed to radiation therapy, the number of BCCs ranged from 1 to >1,000 (median 8) and 1 to 3 (median 2), respectively, in the 2 groups. Jaw cysts occurred in 78/105 (74%) with the first tumor occurring in 80% by the age of 20 years. The number of total jaw cysts ranged from 1 to 28 (median 3). Palmar pits and plantar pits were seen in 87%. Ovarian fibromas were diagnosed by ultrasound in 9/52 (17%) at a mean age of 30 years. Medulloblastoma occurred in 4 patients at a mean age of 2.3 years. Three patients had cleft lip or palate. Physical findings include {open_quotes}coarse face{close_quotes} in 54%, relative macrocephaly in 50%, hypertelorism in 42%, frontal bossing in 27%, pectus deformity in 13%, and Sprengel deformity in 11%.

    Basal cell carcinoma (BCC), the most prevalent form of cancer worldwide, is a malignant skin neoplasm. It is locally invasive, with an exceptional incidence of reported metastasis. It can also be part of the Gorlin-Goltz syndrome, an autosomal dominant genetic disorder with high penetrance and variable expressivity, which is principally characterized by cutaneous BCC, odontogenic keratocysts, palmar and/or plantar pits, and falx cerebri calcification. We report the exceptional clinical observation of a 54-year-old man presenting bone metastasis from BCC in Gorlin-Goltz syndrome. Less than 300 cases of metastatic BCC have been reported in the literature. The present case is the second associated with Gorlin-Goltz syndrome. Copyright 2009 S. Karger AG, Basel.

    Gorlin-Goltz syndrome, also known as nevoid basal cell carcinoma syndrome, is an autosomal dominant inherited disorder which is characterized by the presence of multiple basal cell carcinomas, maxillary keratocysts, and musculoskeletal anomalies. We present a case of a patient suffering from Gorlin-Goltz syndrome who developed an intraosseous basal cell carcinoma associated with a recurrent maxillary keratocyst. To our knowledge, this is the first case of malignant transformation of a keratocyst into a basal cell carcinoma described in the literature. This case highlights the importance of careful histologic examination of keratocysts excised in patients suffering from Gorlin-Goltz syndrome.

    Full Text Available The odontogenic keratocysts (OKC usually represent a particular entity that has been of interest primarily due to biological aggressiveness and to its frequent recurrence. Nevoid basal cell carcinoma syndrome (NBCCS, also known as Gorlin syndrome is a hereditary condition characterized by a wide-range of developmental abnormalities and a predisposition to neoplasms. There are several possible reasons why OKC recur so frequently and require meticulous surgical planning and execution. This article has attempted to show that there is a lack of published evidence regarding the cause of frequent recurrent of OKC that presented in NBCCS. However, the findings of the study revealed differences in opinion regarding the treatment modalities, which necessitates further long term clinical studies that could precisely document certain reliable guidelines in this point of view.

    Peripheral odontogenic keratocyst (POKC) is a rare gingival cyst showing histologic features identical to those of keratocystic odontogenic tumor. A rare case of POKC associated with nevoid basal cell carcinoma syndrome (NBCCS) is presented. A 24-year-old woman with NBCCS presented with a pigmented papule, 3 mm in size, involving the lingual gingiva of the right canine area of the mandible. Based on a clinical diagnosis of benign pigmentation, an excisional biopsy was performed, and a histopathologic diagnosis of POKC was rendered. The lining cells were positive for the proteins GLI2, BCL2, keratin 8, keratin 17, and mTOR. TP53 and Ber-EP4 were also weakly positive. Gene mutational analysis on a buccal swab sample revealed 2 missense mutations in the PTCH1 gene. This case is a distinctive example of a genuine soft tissue counterpart of keratocystic odontogenic tumor, in which an aberrant PTCH1-GLI pathway played a considerable role in the pathogenesis.

    Nevoid basal cell carcinoma syndrome (NBCCS) is an autosomal dominant disorder mainly caused by heterozygous mutations of PTCH1. In addition to characteristic clinical features, detection of a mutation in causative genes is reliable for the diagnosis of NBCCS; however, no mutations have been identified in some patients using conventional methods. To improve the method for the molecular diagnosis of NBCCS. We performed targeted exome sequencing (TES) analysis using a multi-gene panel, including PTCH1, PTCH2, SUFU, and other sonic hedgehog signaling pathway-related genes, based on next-generation sequencing (NGS) technology in 8 cases in whom possible causative mutations were not detected by previously performed conventional analysis and 2 recent cases of NBCCS. Subsequent analysis of gross deletion within or around PTCH1 detected by TES was performed using chromosomal microarray (CMA). Through TES analysis, specific single nucleotide variants or small indels of PTCH1 causing inferred amino acid changes were identified in 2 novel cases and 2 undiagnosed cases, whereas gross deletions within or around PTCH1, which are validated by CMA, were found in 3 undiagnosed cases. However, no mutations were detected even by TES in 3 cases. Among 3 cases with gross deletions of PTCH1, deletions containing the entire PTCH1 and additional neighboring genes were detected in 2 cases, one of which exhibited atypical clinical features, such as severe mental retardation, likely associated with genes located within the 4.3Mb deleted region, especially. TES-based simultaneous evaluation of sequences and copy number status in all targeted coding exons by NGS is likely to be more useful for the molecular diagnosis of NBCCS than conventional methods. CMA is recommended as a subsequent analysis for validation and detailed mapping of deleted regions, which may explain the atypical clinical features of NBCCS cases.

    Nevoid basal cell carcinoma syndrome (NBCCS) is an autosomal dominantly inherited disorder characterized by multiple basal cell carcinomas (BCC), odontogenic tumors and various skeletal anomalies. Basaloid follicular hamartomas (BFHs) constitute rare neoplasms that can be detected in sporadic and familial settings as in the Basaloid Follicular Hamartoma Syndrome (BFHS). Although BFHS shares clinical, histopathological and genetic overlapping with the NBCCS, they are still considered two distinctive entities. The aim of our single-institution study was the analysis of a cohort of PTCH1-mutated patients in order to define clinical and biomolecular relationship between NBCCS and BFHs. In our study we evaluated PTCH1 gene-carrier probands affected by NBCCS to detect the incidence of BFHs and their correlation with this rare syndrome. Among probands we recognized 4 patients with BFHs. We found 15 germline PTCH1 mutations, uniformly distributed across the PTCH1 gene. Six of them had familial history of NBCCS, two of them were novel and have not been described previously. NBCCS and BFHS may be the same genetic entity and not two distinctive syndromes. The inclusion of BFH in the NBCCS cutaneous tumor spectrum might be useful for the recognition of misdiagnosed NBCCS cases that could benefit from tailored surveillance strategies.

    2008-01-01

    The basal cell nevus syndrome (BCNS) is an autosomal dominant disorder, characterized by basal cell carcinomas, odontogenic keratocysts and skeletal abnormalities. We experienced two cases that represented several characteristics of BCNS. Case 1: a thirty three year-old man visited CSU hospital. His radiographs showed four cystic lesions at both maxillary sinus and both mandibular angle, with bifid rib and ectopic calcification of falx cerebri. After marsupialization and enucleation, recurrent and newly developing tendency were found on his follow-up radiographs. Case 2: a seventeen year-old man had four large cystic lesions which were diagnosed as odontogenic keratocysts. He had craniofacial anomalies which included ectopic calcification and frontal bossing.

    Purpose: In 1960 Gorlin and Goltz defined the nevoid basal cell carcinoma syndrome (NBCCS, Gorlin-Goltz Syndrome) as a syndrome comprising multiple basal cell carcinoma, odontogenic keratocysts, and skeletal anomalies. NBCCS is an autosomal dominantly inherited disease with an estimated prevalence of 1:150 000 and diagnosis of this syndrome is often an accidental finding of radiological investigations. The purpose of this study was to report the varied radiological and dermatological manifestations of our patients affected with NBCCS and to present this rare syndrome as a differential diagnosis of skeletal anomalies. Materials and Methods: Between 1994 and 2005 the demographic, clinical, radiological and histological data of 8 patients with NBCCS were retrospectively analyzed. Nevoid basal cell carcinoma syndrome was diagnosed in the event of two major or one major and two minor criteria. The major criteria are more than 2 basal cell carcinoma, odontogenic keratocysts, three or more palmar pits, and calcification of the falx cerebri. Results: Between 1994 and 2005 8 patients (3 females and 5 males) with NBCCS were treated in our departments. The average age at the time of diagnosis of NBCCS was 49.9 years. All patients had a minimum of two major criteria. The major criteria with the most frequency were the basal cell carcinoma (6 patients) and the odontogenic keratocysts (5 patients), followed by the calcification of the falx cerebri and palmoplantar pits (4 patients). There was no gender-related or age-related predilection and only one patient was affected with pain in his fingers which radiologically correlated to small cystic bone lesions (''flame-shaped lucencies'').

    Full Text Available Summary: Rarely, basal cell carcinoma grows to a giant size, invading the underlying deep tissue and complicating the treatment and reconstruction modalities. A giant basal cell carcinoma on the scalp is in some cases treated with a combination of surgery and radiation therapy, resulting in local control, a satisfactory long-term cosmetic and functional result. We present a case with a neglected basal cell scalp carcinoma, treated with wide excision and postoperative radiotherapy, reconstructed with a free latissimus dorsi flap. The cosmetic result is acceptable and there is no sign of recurrence 1 year postoperatively.

  19. Ponticulus posticus is a frequent radiographic finding on lateral cephalograms in nevoid basal cell carcinoma syndrome (Gorlin-Goltz syndrome).

    2014-12-01

    Nevoid basal cell carcinoma syndrome (NBCCS) is a predisposition to a rare tumor type with a variable phenotype. Besides tumors, skeletal alterations, such as bifid ribs or frontal bossing constitute the phenotype. Recently, a variant of the first cervical vertebra, the ponticulus posticus, was reported to occur in 50% of patients with NBCCS as revealed by analysis of lateral cephalograms. Lateral cephalograms of eight patients with NBCCS were studied for the presence of ponticulus posticus. The ponticulus posticus was present in all patients. In one case, a series of cephalograms performed during a period of 20 years allowed the slow and continuous recording of a ponticulus posticus formation. Besides the predisposition to developing neoplasms, NBCCS also affects bone development. Some diagnostic criteria for NBCCS rely on certain osseous transformations either in hard tissues, e.g. keratocystic odontogenic tumor in jaws, or in soft tissues, e.g. calcification of the falx cerebri. Furthermore, the physiognomy can be affected by skeletal alterations, e.g. frontal bossing or hypertelorism. Given this wide spectrum of osseous involvement in NBCCS, the high prevalence rate of ponticulus posticus should be added to the relevant diagnostic findings of the skull and vertebral column. However, the onset of ponticulus posticus formation in the life of such patients is unclear and thus the relevance of this finding in early diagnosis of NBCCS remains to be elucidated.

    The use of eponyms has long been contentious, but many remain in common use, as discussed elsewhere (Editorial: Oral Diseases. 2009: 15; 185). The use of eponyms in diseases of the head and neck is found mainly in specialties dealing with medically compromised individuals (paediatric dentistry, special care dentistry, oral and maxillofacial medicine, oral and maxillofacial pathology, oral and maxillofacial radiology and oral and maxillofacial surgery) and particularly by hospital-centred practitioners. This series has selected some of the more recognized relevant eponymous conditions and presents them alphabetically. The information is based largely on data available from MEDLINE and a number of internet websites as noted below: the authors would welcome any corrections. This document summarizes data about Gorlin-Goltz syndrome.

    Full Text Available Abstract Café au lait spots (CALS are common dermatologic findings that can at the same time arise in a variety of pathologic conditions such as Neurofibromatosis type 1 (NF1, together with numerous hereditary syndromes for which they represent either diagnostic criteria or associated elements (McCune Albright, Silver-Russell, LEOPARD, Ataxia-Telangiectasia. A review of the literature also revealed two cases of association with NBCCS. We report here the case of a female proband with CALS associated to Nevoid Basal Cell Carcinoma Syndrome (NBCCS with known PTCH1 germline mutation (C.1348-2A>G who had been misdiagnosed with NF1 in her childhood because of 5 CALS and cutaneous nodules. The patient presented a giant cell tumor of the skin, palmar and calcaneal epidermoidal cystic nodules, odontogenic keratocystic tumors and deformity of the jaw profile. Her family history brought both her brother and father to our attention because of the presence of KCOTs diagnosed at early age: after genetic testing, the same PTCH1 germline mutation was identified in the three family members. Clinical criteria are used for discerning NF1 diagnosis (size, number and onset age, while there are no definite guidelines concerning CALS except for their presence. In our experience, we have noted an association of CALS with NBCCS; this seems interesting because we already know clinical criteria are a dynamic entity and can be modified by epidemiologic evidences.

    Basal cell carcinoma is the most common skin cancer, characterised by a slow growing behavior, metastasis are extremely rare, and it occurs in less than 0, 1% of all cases. Giant basal cell carcinoma is a rare form of basal cell carcinoma, more aggressive and defined as a tumor measuring more than 5 cm at its largest diameter. Only 1% of all basal cell carcinoma develops to a giant basal cell carcinoma, resulting of patient's negligence. Giant basal cell carcinoma is associated with higher potential of metastasis and even death, compared to ordinary basal cell carcinoma. We report a case of giant basal cell carcinoma metastaticin lung occurring in a 79 years old male patient, with a fatal evolution after one course of systemic chemotherapy. Giant basal cell carcinoma is a very rare entity, early detection of these tumors could prevent metastasis occurrence and improve the prognosis of this malignancy.

    Introduction. Basal cell carcinoma (BCC) is a locally invasive malignant epidermal tumour. Incidence is increasing by 10% per year; incidence of metastases is minimal, but relapses are frequent (40%-50%). The complete excision of the BCC allows reduction of relapse. Materials and Methods. The study cohort consists of 1123 patients underwent surgery for basal cell carcinoma between 1999 and 2009. Patient and tumor characteristics recorded are: age; gender; localization (head and neck, trunk, and upper and lower extremities), tumor size, excisional margins adopted, and relapses. Results. The study considered a group of 1123 patients affected by basal cell carcinoma. Relapses occurred in 30 cases (2,67%), 27 out of 30 relapses occurred in noble areas, where peripheral margin was <3mm. Incompletely excised basal cell carcinoma occurred in 21 patients (1,87%) and were treated with an additional excision. Discussion. Although guidelines indicate 3mm peripheral margin of excision in BCC <2cm, in our experience, a margin of less than 5mm results in a high risk of incomplete excisions

    Full Text Available Basal Cell Carcinoma is the most common human malignant neoplasm. Vulvar basal cell carcinoma is rare, accounting for less than 5% of all vulvar neoplasms. Vulvar basal cell carcinomas are usually diagnosed late because they are often asymptomatic and tend to grow at slow rates. They are usually diagnosed late because they are often asymptomatic. However, these tumours may appear in areas which are normally covered with ultraviolet light. We present the case of a 60 years old woman diagnosed with invasive breast cancer for which she underwent surgery followed by chemotherapy and radiotherapy. The patient presented to our department with an ulcerated vulvar lesion. On inspection, the tumour measured 3/2 cm and was located on the left labium majus. The biopsy confirmed the diagnosis of vulvar basal cell carcinoma and a wide local excision was performed with no relapse at one year. In conclusion, early detection of BCC’s is critical to allow complete surgical cure so any abnormality on the vulva should be biopsied. A wide safety margin of 1cm should be achieved when resecting the tumour and the physician should keep in mind that the BCC’s of the vulva has a high recurrence rate. Previous chemotherapy is not associated with this type of non-melanoma skin cancer.

    DNA repair and replication after in vitro UV irradiation were determined in cultured peripheral blood lymphocytes from 6 patients with nevoid basal cell carcinoma syndrome (NBCCS) and from a group of control donors. DNA repair synthesis (UDS) was measured in unstimulated lymphocytes by incubation with 3H-TdR in the presence of hydroxyurea for 3 and 6 h after UV irradiation (6-48 J/m2). DNA replication was measured in PHA-stimulated lymphocytes, UV-irradiated or mock-irradiated, by incubation with 3H-TdR for 24 h. The effect of the mitogen was followed during 5 days after stimulation by determining the incorporation of 3H-TdR, the increase of cell number, and the mitotic index. NBCCS and control lymphocytes showed equal sensitivity to UV light in terms of UDS and reduced response to PHA. On the contrary, the mitotic index and the number of cells in stimulated cultures were significantly lower in the affected subjects. These data suggest an altered progression along the cell cycle, which could be characteristic of stimulated NBCCS lymphocytes

    2017-11-01

    - Basal cell carcinoma (BCC) is the most common human malignant neoplasm and is a frequently encountered diagnosis in dermatopathology. Although BCC may be locally destructive, it rarely metastasizes. Many diagnostic entities display morphologic and immunophenotypic overlap with BCC, including nonneoplastic processes, such as follicular induction over dermatofibroma; benign follicular tumors, such as trichoblastoma, trichoepithelioma, or basaloid follicular hamartoma; and malignant tumors, such as sebaceous carcinoma or Merkel cell carcinoma. Thus, misdiagnosis has significant potential to result in overtreatment or undertreatment. - To review key features distinguishing BCC from histologic mimics, including current evidence regarding immunohistochemical markers useful for that distinction. - Review of pertinent literature on BCC immunohistochemistry and differential diagnosis. - In most cases, BCC can be reliably diagnosed by histopathologic features. Immunohistochemistry may provide useful ancillary data in certain cases. Awareness of potential mimics is critical to avoid misdiagnosis and resulting inappropriate management.

    2011-01-01

    Basal cell carcinoma (BCC) remains the most common form of non melanoma skin cancer (NMSC) in Caucasians, with perhaps as many as 2 million new cases expected to occur in the United States in 2010. Many treatment options, including surgical interventions and nonsurgical alternatives, have been utilized to treat BCC. In this paper, two non-surgical options, imiquimod therapy and photodynamic therapy (PDT), will be discussed. Both modalities have demonstrated acceptable disease control rates, cosmetically superior outcomes, and short-term cost-effectiveness. Further studies evaluating long-term cure rates and long-term cost effectiveness of imiquimod therapy and PDT are needed.

    syndrome (GGS is an autosomal dominant inherited disorder that mainly predisposes to the proliferation of tumors, such as basal cell carcinomas and jaw keratocysts. GGS is caused by the Patched gene mutation on chromosome 9. Basal cell carcinomas in patients with GGS usually present as multiple tumors, with polymorphic clinical features, a non-gender predilection, sometimes occurring in the early stages of life, and even affecting areas not exposed to sunlight. The clinical behavior may vary, and sometimes can be very aggressive, especially in the face. In order to study the behavior of basal cell carcinomas in GGS patients, a study was performed on the patients who met criteria for the disease and were treated in our hospital in the period between 2001 and 2011. Material and methods: The study included 11 patients with clinical and/or genetic diagnosis of GGS. The patients were studied according sex and age, clinical aspects, histological features, surgical treatment provided, presence of recurrence, and follow-up. Results: Basal cell carcinomas were seen on the face in 36% of the patients. The number of tumors per patient ranged between 9 and 21. The preferred treatment was surgical excision, although all patients developed new lesions and recurrences which required several procedures. The histological study revealed a contact or proximity of the tumor to surgical margins in 28% of lesions. Conclusions: There is insufficient evidence in the literature to determine the treatment of choice among the different methods available for the management of the basal cell carcinoma in GGS. A preventive approach is necessary to avoid sunlight exposure.

    Nevoid basal cell carcinoma syndrome (NBCCS) is an autosomal dominant disorder characterised by developmental defects and tumorigenesis, such as medulloblastomas and basal cell carcinomas, caused by mutations of the patched-1 ( PTCH1 ) gene. In this article, we seek to demonstrate a mosaicism containing double mutations in PTCH1 in an individual with NBCCS. A de novo germline mutation of PTCH1 (c.272delG) was detected in a 31-year-old woman with NBCCS. Gene analysis of two out of four induced pluripotent stem cell (iPSC) clones established from the patient unexpectedly revealed an additional mutation, c.274delT. Deep sequencing confirmed a low-prevalence somatic mutation (5.5%-15.6% depending on the tissue) identical to the one found in iPSC clones. This is the first case of mosaicism unequivocally demonstrated in NBCCS. Furthermore, the mosaicism is unique in that the patient carries one normal and two mutant alleles. Because these mutations are located in close proximity, reversion error is likely to be involved in this event rather than a spontaneous mutation. In addition, this study indicates that gene analysis of iPSC clones can contribute to the detection of mosaicism containing a minor population carrying a second mutation. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    We present an 8-year-old African-American boy with medulloblastoma and nevoid basal cell carcinoma syndrome (NBCCS) who exhibited the radiosensitive response of basal cell carcinoma (BCC) formation in the area irradiated for medulloblastoma. Such a response is well-documented in Caucasian NBCCS patients with medulloblastoma. The propositus was diagnosed with medulloblastoma at the age of 2 years and underwent surgery, chemotherapy, and craniospinal irradiation. At the age of 6 years, he was diagnosed with NBCCS following his presentation with a large odontogenic keratocyst of the mandible, pits of the palms and soles and numerous BCCs in the area of the back and neck that had been irradiated previously for medulloblastoma. Examination of other relatives showed that the propositus mother also had NBCCS but was more mildly affected; in particular, she had no BCCs. This case illustrates complex gene-environment interaction, in that increased skin pigmentation in African-Americans is presumably protective against ultraviolet, but not ionizing, radiation. This case and other similar cases in the literature show the importance of considering NBCCS in the differential diagnosis of any patient who presents with a medulloblastoma, especially before the age of 5 years, and of examining other close relatives for signs of NBCCS to determine the patient`s at-risk status. Finally, for individuals who are radiosensitive, protocols that utilize chemotherapy in lieu of radiotherapy should be considered. 27 refs., 4 figs.

    Red dot basal cell carcinoma is a unique variant of basal cell carcinoma. Including the three patients described in this report, red dot basal cell carcinoma has only been described in seven individuals. This paper describes the features of two males and one female with red dot basal cell carcinoma and reviews the characteristics of other patients with this clinical subtype of basal cell carcinoma. A 70-year-old male developed a pearly-colored papule with a red dot in the center on his nasal tip. A 71-year-old male developed a red dot surrounded by a flesh-colored papule on his left nostril. Lastly, a 74-year-old female developed a red dot within an area of erythema on her left mid back. Biopsy of the lesions all showed nodular and/or superficial basal cell carcinoma. Correlation of the clinical presentation and pathology established the diagnosis of red dot basal cell carcinoma. The tumors were treated by excision using the Mohs surgical technique. Pubmed was searched with the keyword: basal, cell, cancer, carcinoma, dot, red, and skin. The papers generated by the search and their references were reviewed. Red dot basal cell carcinoma has been described in three females and two males; the gender was not reported in two patients. The tumor was located on the nose (five patients), back (one patient) and thigh (one patient). Cancer presented as a solitary small red macule or papule; often, the carcinoma was surrounded by erythema or a flesh-colored papule. Although basal cell carcinomas usually do not blanch after a glass microscope slide is pressed against them, the red dot basal cell carcinoma blanched after diascopy in two of the patients, resulting in a delay of diagnosis in one of these individuals. Dermoscopy may be a useful non-invasive modality for evaluating skin lesions when the diagnosis of red dot basal cell carcinoma is considered. Mohs surgery is the treatment of choice; in some of the patients, the ratio of the area of the postoperative wound to that

    Among over 390,000 routine dermatopathologic specimens there were 85 cases diagnosed as basal cell epithelioma (carcinoma) (BCE) in persons 19 years old or younger. This number was refined to 40 cases de novo BCE in children and teenagers. Basal cell epithelioma unrelated to other conditions is rare in the young and it should be differentiated from similar fibroepithelial growths.

    Basal cell nevus syndrome (BCNS) is principally characterized by cutaneous basal cell carcinomas, multiple odontogenic keratocysts and skeletal abnormalities. Our patient represented several characteristics of BCNS, such as, multiple odontogenic keratocysts, facial nevus, calcification of falx cerebri, parietal bossing and mental retardation. The cyst on posterior mandible showed recurrent and newly developing tendency.

    Full Text Available Background: Development of skin neoplasms is one of the most important chronic complications of radiation therapy. Basal cell carcinoma (BCC is the most frequent carcinoma occurring at the region of the body to which radiotherapy was delivered. Aim: The aim of this study was to evaluate clinical and histological aspects of basal cell carcinoma in patients with a history of radiotherapy. Materials and Methods: Medical records and microscopic slides of 80 patients with basal cell carcinoma who had received radiotherapy (1996-2006 were reviewed in pathology department of Imam Reza hospital of Mashhad, Iran. Collected data were analyzed statistically using descriptive test. Results: 60 men and 20 women were included, majority of them in their sixties. Plaque was the most common clinical pattern of basal cell carcinoma. Fifty one percent of the patients had pigmented and 42.5% had multiple lesions. Scalp was the most common site of involvement. Histologically, macronodular and pigmented carcinoma were the most predominant forms of basal cell carcinoma. Discussion: Majority of patients had scalp involvement and multiple lesions. Nodular and pigmented forms were the most common histological findings. We suggest the need for close supervision in patients with a history of radio therapy in the past.

    Primary treatment of basal cell carcinoma of the lower eyelid and the inner corner is essentially surgical, but advanced lesions require extensive surgical interventions. In some cases it is necessary to continue with the mutilating surgery--exenteration of the orbit. In this work we evaluate the indications of radical solutions in patients with basal cell carcinoma invading the orbit and the subsequent possibility for individually made prosthesis to cover the defect of the cavity. Indications to exenteration of the orbit in patients with basal cell carcinoma findings in 2008-2013. Case report of 2 patients. In period 2008-20013 at the Dept. of Ophthalmology, Comenius University in Bratislava totally 221 patients with histologically confirmed basal cell carcinoma of the eyelids and the inner corner were treated. In 5 cases (2.7 %) with infiltration of the orbit the radical surgical procedure, exenteration was necessary. In 3 patients exenteration was indicated as the first surgical procedure in the treatment of basal cell carcinoma, since they had never visited ophthalmologist before only at in the stage of infiltration of the orbit (stage T4). In one case was indicated exenteration after previous surgical interventions and relapses. After healing the cavity patients got individually prepared epithesis. Surgical treatment of basal cell carcinoma involves the radical removal of the neoplasm entire eyelid and stage T1 or T2 can effectively cure virtually all tumors with satisfactory cosmetic and functional results. In advanced stages (T4 stage) by infiltrating the orbit by basal cell carcinoma exenteration of the orbit is necessary. This surgery is a serious situation for the patient and also for his relatives. Individually made prosthesis helps the patient to be enrolled to the social environment.

  9. Vismodegib (ERIVEDGE°) In basal cell carcinoma: too many unknowns.

    Science.gov (United States)

    2015-01-01

    Basal cell carcinomas are the most common skin cancers. They are usually localised and carry a good prognosis. There is no standard treatment for the rare patients with metastatic basal cell carcinoma or very extensive basal cell carcinoma for whom surgery or radiotherapy is inappropriate. Vismodegib, a cytotoxic drug, is claimed to prevent tumour growth by inhibiting a pathway involved in tissue repair and embryogenesis. It has been authorised in the European Union for patients with metastatic or locally advanced and extensive basal cell carcinoma. Clinical evaluation of vismodegib is based on a non-comparative clinical trial involving 104 patients, providing only weak evidence. Twenty-one months after the start of the trial, 7 patients with metastases (21%) and 6 patients with advanced basal cell carcinoma (10%) had died. Given the lack of a placebo group, there is no way of knowing whether vismodegib had any effect, positive or negative, on survival. There were no complete responses among patients with metastases, but about one-third of them had partial responses. Among the 63 patients with locally advanced basal cell carcinoma, there were 14 complete responses and 16 partial responses. The recurrence rate in patients with complete responses was not reported. Similar results were reported in two other uncontrolled trials available in mid-2014. Vismodegib has frequent and sometimes serious adverse effects, including muscle spasms, fatigue and severe hyponatraemia. Cases of severe weight loss, alopecia, ocular disorders, other cancers (including squamous cell carcinoma) and anaemia have also been reported. More data are needed on possible hepatic and cardiovascular adverse effects. A potent teratogenic effect was seen in experimental animals. As vismodegib enters semen, contraception is mandatory for both men (condoms) and women. In practice, vismodegib has frequent and varied adverse effects, some of which are serious, while its benefits are poorly documented

    The purpose of this study of 81 patients with basal cell carcinoma (BCC) of the nose was to present the oncological and cosmetic results of surgical treatment and compare these results with those of other possible treatments. We report a series of 81 cases of histologically proven BCC of the nose located chiefly on the alae nasi and on the lower end of this organ; 42 p. 100 of the tumors had previously been treated and had recurred. The patients' mean age was 63 years, and the shortest follow-up was 3 years. Excision of the tumor under simple or reinforced local anaesthesia was complete in 88 p. 100 of the cases, incomplete or borderline in 12 p. 100 and systematically repeated. Extemporaneous histological examination was performed in 18 p. 100 of the cases. The operative lesion was repaired with a graft or a flap. There was no postsurgical treatment. The recurrence rate was 4 p. 100 with a minimum follow-up of 3 years. The cosmetic result was good in 78 p. 100 of the patients. Numerous treatments have been used against BCC of the nose, the results, advantages and disadvantages of each of these treatments are given below: 1. Cryosurgery. The problem with this method is that it is relatively difficult to perform and requires reliable operators. The cure rate is similar to that of other treatments. 2. Chemotherapy is not frequently used. 3. Electrocoagulation. Contrary to the conventional excision, this method precludes all histological controls, and the common idea of good oncological results is now being revised. 4. Radiotherapy. The recurrence rate varies from 7 to 11.8 p. 100 with fair cosmetic results. It requires numerous sessions, cannot be repeated in case of recurrence and complicates the surgical treatment. In addition, there is a long-term risk of radiodystrophy. 5. Curietherapy by local implantation of 192Iridium has a recurrence rate of 2.5 to 7 p. 100. This treatment requires hospitalization and is costly. It is indicated in cases of complex surgery

    Evaluate the effectiveness of vismodegib in the management of basal cell carcinoma with orbital extension and/or extensive periocular involvement. Retrospective chart review of 6 consecutive patients with biopsy-proven orbital basal cell carcinoma and 2 additional patients with extensive periocular basal cell carcinoma who were treated with oral vismodegib (150 mg/day) was performed. Basal cell carcinoma extended in the orbit in 6 of 8 patients (involving orbital bones in 1 patient), and 2 of 8 patients had extensive periocular involvement (1 with basal cell nevus syndrome). Vismodegib therapy was the only treatment in 6 patients, off-label neoadjuvant in 1 patient, and adjuvant treatment in 1 patient. Orbital tumors in all 4 patients who received vismodegib as sole treatment showed partial response with a mean 83% shrinkage in tumor size after a median of 7 months of therapy. In the 2 patients receiving vismodegib as neoadjuvant or adjuvant therapies, there was complete response after a median of 7 months of therapy and no evidence of clinical recurrence after discontinuing therapy for a median of 15 months. The 2 patients with extensive periocular involvement experienced complete clinical response after a median 14 months of treatment. During treatment, the most common side effects were muscle spasm (75%) followed by alopecia (50%), dysgeusia (25%), dysosmia, and episodes of diarrhea and constipation (13%). Basal cell carcinoma with orbital extension and extensive periocular involvement responds to vismodegib therapy. The long-term prognosis remains unknown, and additional prospective studies are indicated.

    2008-06-01

    Full Text Available A 75-year-old woman was admitted to our outpatient clinic with a three-year history of a painless, nonhealing ulcer located on the left lower leg. She had no response to previous therapy with local wound care. Skin examination revealed an ulcer 2.7 x 3.7 cm in size, and the surrounding skin showed minimal erythema. The surface of the ulcer demonstrated shiny granulation tissue. Biopsy of the ulcer edge and base showed basal cell carcinoma. Venous Doppler ultrasonography and dermatological examination did not reveal chronic venous insufficiency. Basal cell carcinomas rarely arise from previous long-term ulcers or developing de novo. We suggest that patients who develop non-healing leg ulcers, should be examined for basal cell carcinoma.

    Basal cells are stem/progenitor cells that maintain airway homeostasis, enact repair following epithelial injury, and are a candidate cell-of-origin for lung squamous cell carcinoma. Heterogeneity of basal cells is recognized in terms of gene expression and differentiation capacity. In this Issue, Pagano and colleagues isolate a subset of immortalized basal cells that are characterized by high motility, suggesting that they might also be heterogeneous in their biophysical properties. Motility-selected cells displayed an increased ability to colonize the lung in vivo The possible implications of these findings are discussed in terms of basal cell heterogeneity, epithelial cell migration, and modeling of metastasis that occurs early in cancer evolution.

    International guidelines for management of basal cell carcinoma are reviewed and analyzed for decision-making in the appropriate therapeutic behavior for patients. The different therapies for the treatment of basal cell carcinoma are described. Different therapies are evaluated according to the risk (low or high) of recurrence to determine the appropriate treatment. According to the evidence, low-risk tumors have responded to topical therapy, curettage and electrodesiccation, cryotherapy or simple resection, and high-risk tumors are managed with surgery, radiotherapy or Mohs' micrographic surgery [es

    Basal cell carcinoma is the most common form of cancer in humans and comprises the vast majority of skin cancers. It predominantly affects fair-skinned individuals, and its incidence is rapidly increasing. The objective of the study is to identify the epidemiology, its topography and different histological subtypes of basal cell carcinoma in patients with or without Xeroderma Pigmentosum. A cross-sectional descriptive study was conducted at Manipal Teaching Hospital, Pokhara from Jan 2009 to Dec 2016. Ethical approval was taken from MEMG/IRC/GA. The study included patients with a confirmed diagnosis of basal cell carcinoma irrespective of their age and sex. This study showed 77 individuals with 91 biopsies of BCC including 5 cases of Xeroderma Pigmentosum. The predominant histological subtype was nodular with 41 (53.94%) cases, followed by the 14 (18.42%) cases of pigmented and 10 (13.15%) cases baso-squamous subtype. The most frequent sites of involvement were the head and neck, with predominance in the nasal and orbital region. The mean age was 57.68 years but the basal cell carcinoma in cases of Xeroderma Pigmentosum was seen more in younger age groups. There were 43 (55.84 %) male patients and 34 (44.16 %) female patients with a male to female ratio of 1.26:1. Nodular and pigmented varieties were the most frequent subtypes with nose being the commonest site of involvement. Basal cell carcinomas in cases of Xeroderma Pigmentosum were noted in younger age group with multiple lesions.

    The behaviour of each basal cell carcinoma is known to be different according to the histological growth pattern. Among these aggressive lesions, sclerodermiform basal cell carcinomas are the most common type. This is a challenging-to-treat lesion due to its deep tissue invasion, rapid growth, risk of metastasis and overall poor prognosis if not diagnosed in early stages. To investigate if sclerodermiform basal cell carcinomas are diagnosed later compared to non-sclerodermiform basal cell carcinoma Method: All lesions excised from 2000 to 2010 were included. A pathologist classified the lesions in two cohorts: one with specimens of non-aggressive basal cell carcinoma (superficial, nodular and pigmented), and other with sclerodermiform basal cell carcinoma. For each lesion, we collected patient's information from digital medical records regarding: gender, age when first attending the clinic and the tumor location. 1256 lesions were included, out of which 296 (23.6%) corresponded to sclerodermiform basal cell carcinoma, whereas 960 (76.4%) were non-aggressive subtypes of basal cell carcinoma. The age of diagnosis was: 72.78±12.31 years for sclerodermiform basal cell and 69.26±13.87 years for non-aggressive basal cell carcinoma (Pbasal cell carcinomas are diagnosed on average 3.52 years later than non-aggressive basal cell carcinomas. Sclerodermiform basal cell carcinomas were diagnosed 3.40 years and 2.34 years later than non-aggressive basal cell carcinomas in younger and older patients respectively (P=.002 and P=.03, respectively). retrospective design. The diagnostic accuracy and primary clinic conjecture of sclerodermiform basal cell carcinomas is quite low compared to other forms of basal cell carcinoma such as nodular, superficial and pigmented. The dermoscopic vascular patterns, which is the basis for the diagnosis of non-melanocytic nonpigmented skin tumors, may not be particularly useful in identifying sclerodermiform basal cell carcinomas in early stages

    Full Text Available Nevoid basal cell carcinoma syndrome (also named Gorlin-Goltz syndrome is a rare disease. Commonly seen features include multiple odontogenic keratocysts (OKCs, nevus-like basal cell carcinoma, and bifid ribs. Genetic alterations of the PTCH1 gene are associated with the disease. Herein, we report the case of a 15-year-old girl who presented with multiple OKCs, a bifid rib, ectopic calcification of the falx cer-ebri, and an arachnoid cyst of the cerebrum. No basal cell carcinoma was identified. In addition, a search for genetic alterations was performed on the patient. We identified a genetic mutation of C→T in exon 12 (c.1686 bp and a G→C mutation in intron 13 (g.91665 bp of the PTCH1 gene. Although a similar mutation in exon 12 was reported in a literature search, the mutation in intron 13 has not previously been reported. The patient has continued to be followed-up almost 3 years after the surgery with no recurrence of the OKCs or development of basal cell carcinoma.

    The feasibility of smartphones for in vivo skin autofluorescence imaging has been investigated. Filtered autofluorescence images from the same tissue area were periodically captured by a smartphone RGB camera with subsequent detection of fluorescence intensity decreasing at each image pixel for further imaging the planar distribution of those values. The proposed methodology was tested clinically with 13 basal cell carcinoma and 1 atypical nevus. Several clinical cases and potential future applications of the smartphone-based technique are discussed.

    Full Text Available The Nevoid Basal-Cell Carcinoma Syndrome (NBCC, or as it is also referred to, basal-cell nevus syndrome or Gorlin-Goltz syndrome, is characterized by multiple early-appearing basal cell carcinomas, keratocytosis of the mandible, and anomalies of the ocular, skeletal reproductive system. We describe four patients in the same family, all of them possessing a large number of skin tumors associated with other typical clinical and X-Ray anomalies of NBCC. The definitive treatment of NBCC has yet to be established, however, early diagnosis is very important as well as the periodical follow-up examination of ten patients, mainly due to the transformations in the skin lesions that may occur.

    We report a case of a 46-year-old female who presented with a persistent lesion on the inferior right breast. The lesion was located within the scar from a breast augmentation procedure 12 years ago. The lesion had been treated as several conditions with no improvement. Biopsy revealed a superficial and nodular basal cell carcinoma, and the lesion was successfully removed with Mohs micrographic surgery. Basal cell carcinoma arising in a surgical scar is exceedingly rare with only 13 reported cases to date. This is the first reported case of basal cell carcinoma arising in a breast augmentation scar. We emphasize the importance of biopsy for suspicious lesions or those refractory to treatment, particularly those lesions that form within a scar.

    Full Text Available Retinoids have been used for years as monotherapy and/or in combination for treatment and suppression of cutaneous malignancies in patients with basal cell nevus syndrome, xeroderma pigmentosum, or cutaneous T-cell lymphoma (CTCL basal cell carcinoma (BCC. We report 4 cases with BCC confirmed by histopathology who were treated by short-term systemic acitretin combined with retinoic acid 0.1% cream. The 4 cases with BCC showed good response to the treatment without severe adverse effects during treatment and follow-up. The finding suggests that acitretin may be an appropriate treatment option for elderly patients who require less invasive treatment for BCC.

    Purpose: In 1960 Gorlin and Goltz defined the nevoid basal cell carcinoma syndrome (NBCCS, Gorlin-Goltz Syndrome) as a syndrome comprising multiple basal cell carcinoma, odontogenic keratocysts, and skeletal anomalies. NBCCS is an autosomal dominantly inherited disease with an estimated prevalence of 1:150 000 and diagnosis of this syndrome is often an accidental finding of radiological investigations. The purpose of this study was to report the varied radiological and dermatological manifestations of our patients affected with NBCCS and to present this rare syndrome as a differential diagnosis of skeletal anomalies. Materials and Methods: Between 1994 and 2005 the demographic, clinical, radiological and histological data of 8 patients with NBCCS were retrospectively analyzed. Nevoid basal cell carcinoma syndrome was diagnosed in the event of two major or one major and two minor criteria. The major criteria are more than 2 basal cell carcinoma, odontogenic keratocysts, three or more palmar pits, and calcification of the falx cerebri. Results: Between 1994 and 2005 8 patients (3 females and 5 males) with NBCCS were treated in our departments. The average age at the time of diagnosis of NBCCS was 49.9 years. All patients had a minimum of two major criteria. The major criteria with the most frequency were the basal cell carcinoma (6 patients) and the odontogenic keratocysts (5 patients), followed by the calcification of the falx cerebri and palmoplantar pits (4 patients). There was no gender-related or age-related predilection and only one patient was affected with pain in his fingers which radiologically correlated to small cystic bone lesions (''flame-shaped lucencies'').

    We present two cases of multiple jaw cysts not associated with basal cell nevus syndrome. Case 1 : a nine year-old boy visited CNU Hospital for orthodontic treatment and his radiographs showed cystic lesions surrounding the crowns of teeth 13 and 17 respectively, which were diagnosed as dentigerous cysts. Subsequently, two more cysts were found on his follow-up radiographs in 12 and 15 months. The two cysts were determined to be odontogenic keratocysts. The boy had no skeletal abnormalities and no skin lesions associated with basal cell nevus syndrome. Case 2: a fifty-eight year old man had three impacted third molars with pericoronal radiolucencies, which were diagnosed as dentigerous cysts. He had no additional abnormalities associated with basal cell nevus syndrome. Multiple jaw cysts can occur at any age, and periodic radiographic surveillance may be needed for any cases of impacted tooth.

    Branson, Sara V; McClintic, Elysa; Ozgur, Omar; Esmaeli, Bita; Yeatts, R Patrick

    To explore the clinical features, management, and prognosis of metastatic basal cell carcinoma originating in the orbitofacial region. Ten cases of orbitofacial metastatic basal cell carcinoma were identified by searching databases at 2 institutions from 1995 to 2015. A retrospective chart review was performed. Main outcome measures included patient demographics, lesion size, location of metastases, histologic subtype, recurrence rate, time between primary tumor diagnosis and metastasis, perineural invasion, treatment modalities, and survival from time of metastasis. The median tumor size at largest dimension was 3.3 cm (range, 1.9-11.5 cm), and 6 of 10 patients had at least 1 local recurrence before metastasis (range, 0-2 recurrences). The most common sites of metastasis included the ipsilateral parotid gland (n = 6) and cervical lymph nodes (n = 5). Histologic subtypes included infiltrative (n = 5), basosquamous (n = 2), nodular (n = 1), and mixed (n = 1). The median time from primary tumor diagnosis to metastasis was 7.5 years (range, 0-13). The median survival time from diagnosis of metastasis to last documented encounter or death was 5.3 years (range, 7 months-22.8 years). Treatment regimens included surgical excision, radiotherapy, and hedgehog inhibitors. Based on our findings, the following features may be markers of high risk orbitofacial basal cell carcinoma: 1) increasing tumor size, 2) local recurrence of the primary tumor, 3) aggressive histologic subtype, and 4) perineural invasion. Screening should include close observation of the primary site and tissues in the distribution of regional lymphatics, particularly the parotid gland and cervical lymph nodes.

    Patients with basal cell carcinoma of the skin were treated with combined MTDQ (6,6'-methylene-bis-(2,2,4-trimethyl-1,2-dihydroquinoline)) adminstration and irradiation. Significantly better results were obtained with a skin exposure of 2000 R combined with MTDQ than with the same dose alone. The results were comparable to those obtained with an exposure of 4000 R. MTDQ adminstration induced disease of tissular malonaldehyde concentration and suggested the peroxide-decomposing action of the radiation sensitizer. (Auth.)

    Full Text Available Although basal cell carcinoma (BCC is the most common form of skin cancer, the scalp lesions of BCC have been rarely reported. Giant BCC is defined as a tumor larger than 5 cm in diameter and only 0.5-1 % of all BCCs achieve this size. We report a case of giant BCC on the scalp that was treated with topical coticosteroids and antifungal shampoo for five years. BCC should be considered in the differential diagnosis in erythematous plaque type lesions resistant to therapy with long duration localized on the scalp.

    Heparanase is an enzyme that cleaves heparan sulfate chains. Oligosaccharides generated by heparanase induce tumor progression. Basal cell carcinoma and squamous cell carcinoma comprise types of nonmelanoma skin cancer. Evaluate the glycosaminoglycans profile and expression of heparanase in two human cell lines established in culture, immortalized skin keratinocyte (HaCaT) and squamous cell carcinoma (A431) and also investigate the expression of heparanase in basal cell carcinoma, squamous cell carcinoma and eyelid skin of individuals not affected by the disease (control). Glycosaminoglycans were quantified by electrophoresis and indirect ELISA method. The heparanase expression was analyzed by quantitative RT-PCR (qRTPCR). The A431 strain showed significant increase in the sulfated glycosaminoglycans, increased heparanase expression and decreased hyaluronic acid, comparing to the HaCaT lineage. The mRNA expression of heparanase was significantly higher in Basal cell carcinoma and squamous cell carcinoma compared with control skin samples. It was also observed increased heparanase expression in squamous cell carcinoma compared to the Basal cell carcinoma. The glycosaminoglycans profile, as well as heparanase expression are different between HaCaT and A431 cell lines. The increased expression of heparanase in Basal cell carcinoma and squamous cell carcinoma suggests that this enzyme could be a marker for the diagnosis of such types of non-melanoma cancers, and may be useful as a target molecule for future alternative treatment.

    Full Text Available Basal cell carcinoma (BCC is the most common paraneoplastic disease among human neoplasms. The tumor affects mainly photoexposed areas, most often in the head and seldom appears on genitalia and perigenital region. BCC progresses slowly and metastases are found in less than 0.5% of the cases; however, a considerable local destruction and mutilation could be observed when treatment is neglected or inadequate. Different variants as nodular, cystic, micronodular, superficial, pigment BCC are described in literature and the differential diagnosis in some cases could be difficult. The staging of BCC is made according to Tumor, Node, Metastasis (TNM classification and is essential for performing the adequate treatment. Numerous therapeutic methods established for treatment of BCC, having their advantages or disadvantages, do not absolutely dissolve the risk of relapses. The early diagnostics based on the good knowledge and timely organized and adequate treatment is a precondition for better prognosis. Despite the slow progress and numerous therapeutic methods, the basal cell carcinoma should not be underestimated.

    Ultraviolet light (UV) is an important risk factor for cutaneous basal cell carcinoma, cutaneous squamous cell carcinoma and cutaneous melanoma of the skin. These cancers most commonly affect persons with fair skin and blue eyes who sunburn rather than suntan. However, each of these cancers appears to be associated with a different pattern of UV exposure and to be mediated by different intracellular molecular pathways.Some melanocortin 1 receptor (MC1R) gene variants play a direct role in the pathogenesis of cutaneous basal cell carcinoma, cutaneous squamous cell carcinoma and cutaneous melanoma apart from their role in determining a cancer-prone pigmentory phenotype (fair skin, red hair, blue eyes) through their interactions with other genes regulating immuno-inflammatory responses, DNA repair or apoptosis.In this short review we focus on the aetiological role of UV in cutaneous basal cell carcinoma, cutaneous squamous cell carcinoma and cutaneous melanoma of the skin, and on some associated biopathological events.

    Basal cell carcinoma (BCC) is the most common eyelid malignancy; however, orbital invasion by periocular BCC is rare, and management remains challenging. Established risk factors for orbital invasion by BCC include male gender, advanced age, medial canthal location, previous recurrences, large tumor size, aggressive histologic subtype and perineural invasion. Management requires a multidisciplinary approach with orbital exenteration remaining the treatment of choice. Globe-sparing treatment may be appropriate in selected patients and radiotherapy and chemotherapy are often used as adjuvant therapies for advanced or inoperable cases, although the evidence remains limited. We aim to summarize the presentation and treatment of BCC with orbital invasion to better guide the management of this complex condition.

  2. Novel Hedgehog pathway targets against basal cell carcinoma

    The Hedgehog signaling pathway plays a key role in directing growth and patterning during embryonic development and is required in vertebrates for the normal development of many structures, including the neural tube, axial skeleton, skin, and hair. Aberrant activation of the Hedgehog (Hh) pathway in adult tissue is associated with the development of basal cell carcinoma (BCC), medulloblastoma, and a subset of pancreatic, gastrointestinal, and other cancers. This review will provide an overview of what is known about the mechanisms by which activation of Hedgehog signaling leads to the development of BCCs and will review two recent papers suggesting that agents that modulate sterol levels might influence the Hh pathway. Thus, sterols may be a new therapeutic target for the treatment of BCCs, and readily available agents such as statins (HMG-CoA reductase inhibitors) or vitamin D might be helpful in reducing BCC incidence

    Full Text Available We present a 103 - year - old patient, with duration of complaints of about ten years. The initial complaint had been presented as a small nodule, located on the eyebrow, which subsequently ulcerated and encompassed larger regions of the upper and lower eyelids. For the past three years, the patient also had complaints of a worsening of his vision, without seeking for medical help. Within the dermatological examination, an intraocular and periocular localised tumour was established, characterised by a raised peripheral edge and central ulceration. More careful examination revealed that the bulb was fully consumed. The patient refused further diagnosis and treatment. Advanced basal cell carcinomas with intraocular invasion are rare in general. If the patient refuses surgery, radiotherapy and systemic therapy with modern medications such as Vismodegib or Sonidegib are available as treatment options.

    Dariers disease (DD), also known as Keratosis Follicularis or Dariers-White disease, is a rare disorder of keratinisation. DD can present as a generalized autosomal dominant condition as well as a localized or segmental post zygotic condition (Vasquez et al., 2002). Clinical features of DD include greasy, warty papules and plaques on seborrhoeic areas, dystrophic nails, palmo-plantar pits, and papules on the dorsum of the hands and feet. Objective. We report a case of basal cell carcinoma developing in a patient with type 2 segmental DD. Conclusion. According to the current literature, Type 2 segmental disease is a rare presentation of Dariers disease with only 8 previous cases reported to date. In addition, non melanoma skin cancer (NMSC) arising from DD is rarely reported; however, there may be an association between DD and risk of carcinogenesis.

    2015-01-01

    Cutaneous carcinosarcoma is a rare primary tumor of the skin, characterized by biphasic epithelial and mesenchymal differentiation. Due to the limited number of cases reported, there is no consensus regarding treatment and prognosis. Some authors suggest that cutaneous carcinosarcomas should be viewed as aggressive tumors, with ancillary imaging used to evaluate potential metastatic disease. Other reports demonstrate an indolent disease course, especially with epidermal-type cutaneous carcinosarcomas. We report a case of cutaneous carcinosarcoma, which we treated with electrodessication and curettage following a shave biopsy. The tumor had an epithelial component resembling a basal cell carcinoma and a fibrosarcomatous stroma. At 1-year follow-up, our patient did not show evidence of recurrence or metastasis. Our case suggests that a cutaneous carcinosarcoma with an epithelial component composed of basal cell carcinoma can be regarded as a high-risk nonmelanoma skin cancer. © The Author(s) 2015.

    Treatment of superficial basal cell carcinoma with topical 5-aminolevulinic acid photodynamic therapy (ALA-PDT) offers an alternative to plastic surgery and radiotherapy with potential for good cosmetic outcome and local control of disease. We report our clinical experience with this technique. Patients were treated prospectively on a study protocol enrolling a total of 118 patients (63 male, 55 female) with an average age of 65 years. Consecutive patients meeting eligibility criteria were invited to participate over a four year period. Median followup was 27 months (range 1 to 76 months). In the study group, 62 patients had single lesions and 56 had multiple lesions. Of the 56 patients with multiple lesions, 33 had 2-4 lesions, 11 had 5-9, and 11 had 10 or more. All patients were treated with 20% ALA dissolved in Glaxal Base applied to the tumors for three to four hours. Following removal of the cream, fluorescence intensity and distribution were assessed using a UV-A lamp, and the lesions were exposed to photoactivating light of wavelength greater than 600 nm for a light dose ranging from 100-150 J/cm2. Lesions were reassessed in followup, and scored as complete or partial responses. At subsequent patient assessments, lesions were scored as continued complete responses or recurrences. In the patients with single lesions, there was an initial complete response rate of 90.3%. Of the 56 patients with multiple lesions, 44 had all of their lesions respond completely, and there was an overall average response rate of 95.5%. Sixty three percent of males and 44% of females had all of their lesions respond completely. (p=0.033, Chi-squared test). There was no difference in response rate with respect to age, or site of lesion. The recurrence rates were 35% for patients with single lesions, and 10.5% for patients with multiple lesions. ALA-PDT would appear to be a promising alternative to conventional treatment for superficial basal cell carcinoma. Based on these results

    The cancer stem cell model states that a subset of tumor cells, called "cancer stem cells," can initiate and propagate tumor growth through self-renewal, high proliferative capacity, and their ability to recreate tumor heterogeneity. In basal cell carcinoma (BCC), we have shown that tumor cells that express the cell surface protein CD200 fulfill the cancer stem cell hypothesis. CD200+ CD45- BCC cells represent 0.05-3.96% of all BCC cells and reside in small clusters at the tumor periphery. Using a novel, reproducible in vivo xenograft growth assay, we determined that tumor-initiating cell (TIC) frequencies are approximately 1 per 1.5 million unsorted BCC cells. The CD200+ CD45- BCC subpopulation recreated BCC tumor growth in vivo with typical histological architecture and expression of sonic hedgehog-regulated genes. Reproducible in vivo BCC growth was achieved with as few as 10,000 CD200+ CD45- cells, representing ~1500-fold enrichment. The methods used to identify and purify CD200+ CD45- BCC cells, as well as characterize gene expression, are described herein.

    Basal cell carcinoma (BCC) of the nipple-areola complex is uncommon. It has been suggested that BCCs in this region behave more aggressively, with a higher potential for distant spread, than in other anatomical sites. To address questions about etiology, behavior, optimal treatment, and prognosis of this entity. A literature search identifying all cases of BCC of the nipple and nipple-areola complex in the English literature from 1893 to 2008. Thirty-four cases of BCC of the nipple, areola, or both were identified, mostly affecting middle-aged men. The majority of patients were treated with tissue-sparing surgery. There was a metastatic rate of 9.1%, and one patient died from the disease (3.0%). The optimal treatment of this condition should be local excision, but patients with this condition should be followed up for primary site recurrence and axillary metastasis, because there is greater incidence than with BCC at other anatomical sites. Furthermore, proven axillary metastasis should be surgically treated.

    Lichenoid keratosis (LK), also known as benign lichenoid keratosis or lichen planus-like keratosis, is a solitary, pink to red-brown scaly plaque representing a host immunological response to a variety of precursor lesions. LK is often misdiagnosed as a dermatological malignancy owing to its clinical resemblance to basal cell carcinoma (BCC) or Bowen disease. We performed a retrospective analysis of the pathology records of a series of LK lesions with reference to the demographic features and accuracy of clinical diagnosis. The pathology records from 2008 to 2009 of 263 consecutive patients with a histological diagnosis of LK from a specialized skin laboratory were retrieved. Data relating to clinical diagnosis, age, sex, anatomical location, time of year of presentation and any coexistent pathological lesions adjacent to the LK were recorded. Mean age at presentation was 64 years (range 34-96), and 58% of patients were female. The most common anatomical site was the chest/anterior torso, followed by the back and legs. The most common coexisting lesion was solar keratosis at 14%, followed by seborrhoeic keratosis (SK) at 7.8%. The correct clinical diagnosis of LK was made in 29.5% of cases. The most common clinical diagnosis was BCC (47%), while SK was the preferred diagnosis in 18%. A clinical diagnosis was not given in 5.5% of cases. In conclusion, it appears that LK is frequently misdiagnosed, with misdiagnosis occurring in > 70% of cases in this study. © 2017 British Association of Dermatologists.

    The Hedgehog pathway has been identified as a key element in the development of many forms of cancer. Smoothened (Smo) inhibitors are known to beneficially interfere with the Hedgehog pathway and are currently under investigation as anticancer drugs for many tumor entities. Reviewed here are the most recent developments in clinical research on Smo inhibitors for the treatment of advanced basal cell carcinoma (BCC). When reviewing the literature of the past 12 months, it is striking to see the rapid evolution of the field. Compounds that have been presented as powerful new drug candidates 12 months ago have now been discontinued, whereas new ones have emerged. Reports on 13 drug candidates have been identified: one marketed, vismodegib, eight currently under development (phase I-II) and four for which clinical investigation for BCC is currently not being pursued. Smo inhibitors are a promising drug class for the treatment of BCC. To date, most candidates are in early stage development and are expected to enter the market in approximately 5-8 years, if successful.

    Although tumors on the surface of the skin are considered to be easily recognizable, neglected advanced skin neoplasms are encountered even in the 21st century. There can be numerous causes of the delay in the diagnosis: fear of the diagnosis and the treatment, becoming accustomed to a slowly growing tumor, old age, a low social milieu, and an inadequate hygienic culture are among the factors leading some people not to seek medical advice. The treatment of such advanced neoplasms is usually challenging. The therapy of neglected cases demands an individual multidisciplinary approach and teamwork. Basal cell carcinoma (BCC), the most common cutaneous tumor, usually develops in the elderly, grows slowly, and has an extremely low metastatic potential; these factors are suggesting that BCCs might well be the "ideal candidates"for neglected tumors. Five neglected advanced cases of BCC were diagnosed in our dermatological institute between 2000 and 2009. The clinical characteristics and treatment modalities of these neoplasms are discussed, together with the possible causes of the neglect.

    Full Text Available Development of multiple basal cell carcinomas is commonly associated with immunosuppression or genetic disorders. The latter include congenital diseases such as Gorlin-Goltz syndrome, also known as nevoid basal cell carcinoma syndrome, or basal cell nevus syndrome. It is an autosomal dominant inherited disorder characterized by the development of multiple basal cell carcinomas at an early age and a variable combination of other phenotypic abnormalities that result in multiple organ involvement. The susceptibility gene was mapped to chromosome 9q22.3-3.1. Like other tumor suppressor genes, PTCH1 gene shows frequent deletion and a whole variety of other mutations. A high rate of new mutations and the variable expressivity of the condition make full diagnostic assessment difficult, especially in mildly affected individuals with no family history of the condition. It has been postulated that the presence of two major features or one major feature with two minor features classify a condition as Gorlin-Goltz syndrome.

    Basal cell carcinoma (BCC) is the most common type of skin cancer in Germany. So far, it is unclear whether regional variations exist in the health care of the BCC. Analysis of regional variations in health care (e. g., skin cancer screening) and their causes using the example of BCC. Qualitative and quantitative analysis of the regional health care situation of BCC based on three studies was undertaken. These studies include the analysis of n = 7015 histopathological indications whose average tumor thickness is regarded as a characteristic of the quality of care, and a secondary data analysis of GK insured (n = 6.1 million DAK-insured persons), and a nationwide survey (FORSA) of n = 1004 participants focusing on the use of skin cancer screening. Analysis of the histopathological examination showed regional variations in average tumor depth of penetration. These are associated with the rural/urban characteristics of the region and individual sociodemographic indicators (e. g., employment sector or education). The results for age- and gender-specific use (DAK data) showed higher participation rates regarding skin cancer screening in western than in eastern federal states (Bundesländer). Moreover, it was revealed that the trend for using skin cancer screening was higher in urban than in rural areas. The results of population-related surveys confirm this trend. Although it is not possible to compare the studies directly, all three showed an association between city/state and the use of skin cancer screenings. In addition, sociodemographic characteristics that are related to the quality of health care were identified.

    Fibroblast cells derived from nevoid basal carcinoma syndrome (NBCCS) patients show increased levels of DNA synthesis after X-ray irradiation. Genes, whose expression is modulated in association with the DNA synthesis induction, were searched by using PCR-based mRNA differential display analysis in one of the NBCCS cell lines, NBCCS1 cells. Decreased levels of SMT3A gene expression were found in X-ray-irradiated NBCCS1 cells. This decrease was also shown by RT-PCR analysis in another cell line, NBCCS3 cells. In addition to NBCCS cells, normal fibroblast cells showed the DNA synthesis induction after X-ray irradiation when they were treated with antisense oligonucleotides (AO) for SMT3A. However, treatment of normal fibroblasts with the random oligonucleotides (RO) resulted in decreased levels of DNA synthesis after X-ray irradiation. Thus, down-regulation of SMT3A gene expression may be involved in the DNA synthesis induction after X-ray irradiation in the NBCCS cells at least tested

    Excessive ultraviolet radiation (UVR) exposure is the primary predisposing factor for basal cell carcinoma (BCC). However, surprisingly, BCCs occur very rarely on the dorsal hand, which is subject to intense sun exposure, and their infrequent presentation in this location suggests that other factors besides UVR may play a role in BCC pathogenesis. Because dorsal hand BCCs are uncommon, knowledge of their characteristics is limited, and more data are needed to describe their clinical presentation and treatment. To perform an updated review of the literature on the management of dorsal hand BCCs. The authors conducted a comprehensive literature review by searching the PubMed database with the key phrases "basal cell carcinoma dorsal hand," "basal cell carcinoma hand," and "basal cell carcinoma finger," and "basal cell carcinoma thumb." The authors identified 176 cases of dorsal hand BCCs in the literature, 120 of which had sufficient data for analysis. Only 4 cases were treated with Mohs micrographic surgery (MMS). The authors present 14 additional cases of dorsal hand BCCs treated with MMS. Basal cell carcinomas on the dorsal hand occur infrequently, and potential risk factors include being a male of white descent and personal history of skin cancer. Mohs micrographic surgery seems to be an effective treatment method.

    Basal cell carcinoma of the umbilicus is very rare. The nodular subtype is the main representative. Giant basal cell carcinomas represent around 1% of all basal cell carcinomas. The hedgehog pathway inhibitor vismodegib is indicated for advanced basal cell carcinoma and CD56-negative immunostaining seems indicative for successful treatment. A 54-year-old man presented a 10 cm × 14 cm large and 4.5 cm deep morphea-form basal cell carcinoma with faint immunohistochemical CD56 expression arising from the umbilicus. A sequential treatment was initiated with debulking using vismodegib 150 mg per day for 4 months, followed by reconstructive surgery. To the best of our knowledge, this is the first report of a giant basal cell carcinoma of the morphea-form type of the umbilicus. The sequential treatment plan reduces the duration of vismodegib inherent adverse effects and significantly reduces the tumor mass prior to surgery. Besides increasing adherence to vismodegib treatment, this approach facilitates the surgical technique and improves cosmetic outcome.

Ultraviolet radiation exposure, including tanning bed use, as well as host factors play a role in its development. The majority of cases are treated and cured with local therapies including surgery. Yet, the health care costs of diagnosis and treatment of BCCs in the US is substantial. In the United States, the cost of nonmelanoma skin cancer care in the Medicare population is estimated to be US$426 million per year. While rare, locally advanced BCCs that can no longer be controlled with surgery and/or radiation, and metastatic BCCs do occur and can be associated with significant morbidity and mortality. Vismodegib (GDC-0449, a smoothened inhibitor targeted at the hedgehog pathway, is the first US Food and Drug Association (FDA-approved agent in the treatment of locally advanced, unresectable, and metastatic BCCs. This class of agents appears to be changing the survival rates in advanced BCC patients, but appropriate patient selection and monitoring are important. Multidisciplinary assessments are essential for the optimal care and management of these patients. For some patients with locally advanced BCC, treatment with a hedgehog inhibitor may eliminate the need for an excessively disfiguring or morbid surgery.

    Electrochemotherapy (ECT), by combining manageable cytotoxic agents with short electric pulses, represents an effective palliative skin-directed therapy. The accumulated evidence indicates that ECT stands out as a safe and well-tolerated alternative treatment for patients with multiple or large basal cell carcinoma (BCC), who are not suitable for conventional treatments. However, long-term data and shared indications are lacking. In this observational study, we retrospectively analyzed 84 prospectively collected patients with multiple, recurrent or locally advanced BCC who were not candidate for standard therapies and received bleomycin-based ECT according to the European Standard Operative Procedures of ECT, from 2006 to 2016. Disease extent was local, locally advanced and metastatic in 40 (48%), 41 (49%) and 3 (3%), respectively. Forty-four (52%) individuals had multiple BCCs. Grade 3 skin toxicity after ECT was observed in 6% of cases. Clearance rate was 50% (95% CI 39-61%). Primary presentation (p = 0.004), tumor size <3 cm (p < 0.001), well-defined borders (p = 0.021), absence of tumor ulceration (p = 0.001), non-aggressive BCC histology (p = 0.046) and age ≤69 years were associated with higher complete response rate. In patients with local BCC, the clearance rate was 72.5 and 85% after one or two ECT cycles, respectively. In the laBCC group, 32 patients (78%) achieved an objective response. Five-year recurrence rate for local and laBCC was 20 and 38%, respectively (p ≤ 0.001). One or two ECT cycles with bleomycin may be a valuable palliative treatment in well-selected patients with multiple BCCs and favorable tumor features. Validation of predictive factors will be imperative to match patients with optimal ECT treatment modalities. Management of laBCC with ECT warrants further investigation.

    Basal cell carcinoma is the most common skin cancer. Myoepithelial cells are specialized epithelial cells. Basal cell carcinoma with myoepithelial differentiation is a rare tumor. A 71-year-old man with a basal cell carcinoma with myoepithelial differentiation that presented as an asymptomatic red papule of two months duration on his forehead is described. Including the reported patient, this variant of basal cell carcinoma has been described in 16 patients: 11 men and five women. The patients ranged in age at diagnosis from 43 years to 83 years; the median age at diagnosis was 66 years. All of the tumors were located on the face-most were papules or nodules of less than 10 x 10 mm. Their pathology demonstrated two components: one was that of a typical basal cell carcinoma and the other was myoepithelioma-like in which the tumor cells were plasmacytoid or signet ring in appearance and contained abundant eosinophilic cytoplasm or hyaline inclusions or both. The myoepithelial tumor cells had variable immunohistochemical expression that included not only cytokeratin but also actin, glial fibrillary acid protein, S100, and vimentin. The most common clinical impression, prior to biopsy, was a basal cell carcinoma. The pathologic differential diagnosis included cutaneous mixed sweat gland tumor of the skin, myoepithelioma, myoepithelial carcinoma, and tumors that contain a prominent signet ring cell component (such as metastatic gastrointestinal and breast carcinoma, melanoma, plasmacytoid squamous cell carcinoma, and T-cell lymphoma). Mohs micrographic surgical excision, with complete removal of the tumor, was recommended for treatment of the carcinoma.

    Basal cell carcinoma (BCC) of the skin is driven by aberrant hedgehog signaling. Thus blocking this signaling pathway by small molecules such as vismodegib inhibits tumor growth. Primary cilium in the epidermal cells plays an integral role in the processing of hedgehog signaling-related proteins. Recent genomic studies point to the involvement of additional genetic mutations that might be associated with the development of BCCs, suggesting significance of other signaling pathways, such as WNT, NOTCH, mTOR, and Hippo, aside from hedgehog in the pathogenesis of this human neoplasm. Some of these pathways could be regulated by noncoding microRNA. Altered microRNA expression profile is recognized with the progression of these lesions. Stopping treatment with Smoothened (SMO) inhibitors often leads to tumor reoccurrence in the patients with basal cell nevus syndrome, who develop 10-100 of BCCs. In addition, the initial effectiveness of these SMO inhibitors is impaired due to the onset of mutations in the drug-binding domain of SMO. These data point to a need to develop strategies to overcome tumor recurrence and resistance and to enhance efficacy by developing novel single agent-based or multiple agents-based combinatorial approaches. Immunotherapy and photodynamic therapy could be additional successful approaches particularly if developed in combination with chemotherapy for inoperable and metastatic BCCs. © 2017 Wiley Periodicals, Inc.

    Red dot basal cell carcinoma is a distinct but rare subtype of basal cell carcinoma (BCC). It presents as a red macule or papule; therefore, in most cases, it may easily be mistaken for a benign vascular lesion, such as a telangiectasia or angioma. A red dot BCC in an older woman is described. Clinical and histological differences between red dot BCCs and telangiectasias are described. A 72-year-old woman initially presented with a painless red macule on her nose. Biopsy of the lesion established the diagnosis of a red dot BCC. Pubmed was searched for the following terms: angioma, basal cell carcinoma, dermoscope, diascopy, red dot, non-melanoma skin cancer, telangiectasia, and vascular. The papers were reviewed for cases of red dot basal cell carcinoma. Clinical and histological characteristics of red dot basal cell carcinoma and telangiectasias were compared. Red dot BCC is an extremely rare variant of BCC that may be confused with benign vascular lesions. Although BCCs rarely metastasize and are associated with low mortality, they have the potential to become locally invasive and destructive if left untreated. Thus, a high index of suspicion for red dot BCC is necessary. J Drugs Dermatol. 2016;15(5):645-647.

    Ultraviolet radiation is a well-known risk factor for basal cell carcinoma (BCC). Therefore, the high incidence of BCCs in sun-exposed areas such as the head and neck is unsurprising. However, unexpectedly, BCCs on the sun-protected dorsal foot have also been reported, and tumor occurrence here suggests that other factors besides ultraviolet radiation may play a role in BCC pathogenesis. Because only few dorsal foot BCCs have been reported, data on their clinical features and management are limited. To perform an updated review of the literature on clinical characteristics and treatment of dorsal foot BCCs. We conducted a comprehensive literature review by searching the PubMed database with the key phrases "basal cell carcinoma dorsal foot," "basal cell carcinoma foot," and "basal cell carcinoma toe." We identified 20 cases of dorsal foot BCCs in the literature, 17 of which had sufficient data for analysis. Only 1 case was treated with Mohs micrographic surgery. We present 8 additional cases of dorsal foot BCCs treated with Mohs micrographic surgery. Basal cell carcinomas on the dorsal foot are rare, and potential risk factors include Caucasian descent and personal history of skin cancer. Mohs micrographic surgery seems to be an effective treatment option.

The lesion had been present for 10 years and had recently enlarged, associated with bleeding. Histopathologically, the tumor consisted of three distinct parts: The first part showed massive aggregation of basophilic basaloid cells with peripheral palisading and abundant melanin granules, and was diagnosed as solid-type basal cell carcinoma. The second part showed aggregation of clear cells with squamous eddies, and was diagnosed as proliferating trichilemmal tumor. The third part showed reticular aggregation of basaloid cells with infundibular cysts in the papillary dermis, and was diagnosed as infundibulocystic basal cell carcinoma. We diagnosed this tumor as basal cell carcinoma with various forms of hair follicle differentiation, including differentiation into the outer root sheath.

    Basal cell carcinoma (BCC) is the commonest tumor in human. About 70% sporadic BCCs bear somatic mutations in the PATCHED1 tumor suppressor gene which encodes the receptor for the Sonic Hedgehog morphogen (SHH). PATCHED1 germinal mutations are associated with the dominant Nevoid Basal Cell Carcinoma Syndrome (NBCCS), a major hallmark of which is a high susceptibility to BCCs. Although the vast majority of sporadic BCCs arises exclusively in sun exposed skin areas, 40 to 50% BCCs from NBCCS patients develop in non photo-exposed skin. Since overwhelming evidences indicate that microenvironment may both be modified by- and influence the- epithelial tumor, we hypothesized that NBCCS fibroblasts could contribute to BCCs in NBCCS patients, notably those developing in non photo-exposed skin areas. The functional impact of NBCCS fibroblasts was then assessed in organotypic skin cultures with control keratinocytes. Onset of epidermal differentiation was delayed in the presence of primary NBCCS fibroblasts. Unexpectedly, keratinocyte proliferation was severely reduced and showed high levels of nuclear P53 in both organotypic skin cultures and in fibroblast-led conditioning experiments. However, in spite of increased levels of senescence associated β-galactosidase activity in keratinocytes cultured in the presence of medium conditioned by NBCCS fibroblasts, we failed to observe activation of P16 and P21 and then of bona fide features of senescence. Constitutive extinction of P53 in WT keratinocytes resulted in an invasive phenotype in the presence of NBCCS fibroblasts. Finally, we found that expression of SHH was limited to fibroblasts but was dependent on the presence of keratinocytes. Inhibition of SHH binding resulted in improved epidermal morphogenesis. Altogether, these data suggest that the repertoire of diffusible factors (including SHH) expressed by primary NBCCS fibroblasts generate a stress affecting keratinocytes behavior and epidermal homeostasis.

    Of 47 elderly patients treated by simple radiotherapeutic techniques for basal cell carcinomas, 12 are alive and free of disease more than 10 years after treatment. They were asked to rate their perception of the current cosmetic appearance of their lesions on a scale consisting of: excellent, very good, good, mediocre, and poor. Six of the 12 rated their cosmetic appearance as excellent, three considered it very good, and three called it good. Despite undeniable objective deterioration of the cosmetic appearance of irradiated basal cell carcinomas, patients appear to be pleased with the results. (author)

    Full Text Available Xeroderma pigmentosum (XP is characterized by hypersensitivity to sunlight, ocular involvement, and progressive neurological complications. These manifestations are due to a cellular hypersensitivity to ultraviolet radiation leading to a defect in repair of DNA by the process of nucleotide excision repair. Basal cell carcinoma which is rare in children can occur with XP. Though the XP induced changes are predominately dermatologic, pose several challenges in anaesthetic management. Hence, we are reporting a 9-year-old child with XP scheduled for excision of basal cell carcinoma under general anaesthesia.

    The aim of this study is to measure and compare the dynamic thiol/disulphide homeostasis of patients with basal cell carcinoma and healthy subjects with a newly developed and original method. Thirty four patients attending our outpatient clinic and clinically and histopathologically diagnosed as nodular basal cell carcinoma, and age and gender matched 30 healthy individuals have been involved in the study. Thiol/disulphide homeostasis tests have been measured with a novel automatic spectrophotometric method developed and the results have been compared statistically. Serum native thiol and disulphide levels in the patient and control group show a considerable variance statistically (p = 0.028, 0.039, respectively). Total thiol levels do not reveal a considerable variation (p = 0.094). Disulphide/native thiol ratios and native thiol/total thiol ratios also show a considerable variance statistically (p = 0.012, 0.013, 0.010, respectively). Thiol disulphide homeostasis in patients with basal cell carcinoma alters in the way that disulphide gets lower and thiols get higher. Thiol/disulphide level is likely to have a role in basal cell carcinoma pathogenesis.

    Full Text Available Abstract Introduction Perineural invasion is a unique route for tumor dissemination. In basal cell carcinomas, the incidence is low, but increases in advanced cases. Its importance is recognized but not fully understood. Objective To compare head and neck basal cell carcinomas with and without perineural invasion. Methods A retrospective medical chart review of multidisciplinary surgeries for basal cell carcinomas that required a head and neck surgery specialist in a tertiary referral center was performed. Clinical-demographics and histopathological features were analyzed. Results Of 354 cases, perineural invasion was present in 23.1%. Larger tumors and morpheaform subtype were statistically related to perineural invasion. Nodular and superficial subtypes were less frequent in positive cases. No significant difference was found in gender, age, ulceration, location, and mixed histology. Conclusion In this series of selected patients with basal cell carcinomas submitted to major resections, perineural invasion was clearly related to morpheaform subtype and to larger tumors. Other classically associated features, such as location in high-risk mask zone of the face, male gender and mixed histology, were not so strongly linked to perineural invasion.

    Background: Reflectance confocal microscopy (RCM) is a noninvasive imaging technique. Currently, RCM is mainly used for the diagnosis of melanoma and nonmelanoma skin cancer including basal cell carcinoma (BCC). Until now, it has not been possible to distinguish between subtypes of BCC using RCM.

    Basal cell carcinoma (BCC) is 10 times more frequent in organ transplant recipients (OTRs) than in the general population. Factors in OTRs conferring increased susceptibility to BCC include ultraviolet radiation exposure, immunosuppression, viral infections such as human papillomavirus, phototype and genetic predisposition. The PTCH1 gene is a negative regulator of the hedgehog pathway, that provides mitogenic signals to basal cells in skin. PTCH1 gene mutations cause naevoid BCC syndrome, and contribute to the development of sporadic BCC and other types of cancers. Associations have been reported between PTCH1 polymorphisms and BCC susceptibility in nontransplanted individuals. To search for novel common polymorphisms in the proximal 5' regulatory region upstream of PTCH1 gene exon 1B, and to investigate the possible association of PTCH1 polymorphisms and haplotypes with BCC risk after organ transplantation. Three PTCH1 single nucleotide polymorphisms (rs2297086, rs2066836 and rs357564) were analysed by restriction fragment length polymorphism analysis in 161 northern Italian OTRs (56 BCC cases and 105 controls). Two regions of the PTCH1 gene promoter were screened by heteroduplex analysis in 30 cases and 30 controls. Single locus analysis showed no significant association. Haplotype T(1686)-T(3944) appeared to confer a significantly higher risk for BCC development (odds ratio 2.98, 95% confidence interval 2.55-3.48; P = 0.001). Two novel rare polymorphisms were identified at positions 176 and 179 of the 5'UTR. Two novel alleles of the -4 (CGG)(n) microsatellite were identified. No association of this microsatellite with BCC was observed. Haplotypes containing T(1686)-T(3944) alleles were shown to be associated with an increased BCC risk in our study population. These data appear to be of great interest for further investigations in a larger group of transplant individuals. Our results do not support the hypothesis that common polymorphisms in the proximal 5

    Giant basal cell carcinoma, in which the tumour measures 5 cm or greater in diameter, is a very rare skin malignancy that accounts for less than 1 per cent of all basal cell tumours. Very few studies have reported on the incidence, resection and reconstruction of this lesion worldwide. In total, 17 patients with giant basal cell carcinoma of the head and neck region underwent surgical excision and reconstruction at our hospital. Medical charts were retrospectively reviewed and analysed. The lesion was usually in the forehead, eyelid, lips or nasal-cheek region. The greatest diameter ranged from 5 to 11 cm, with 5-6 cm being the most common size at the time of presentation. All patients had their tumour resected and reconstructed in a single-stage procedure, mostly with a local advancement flap, and with no post-operative flap failure. Giant basal cell carcinoma of the head and neck can be successfully treated with a local flap in a single-stage approach.

    Purpose: To review the factors that influence outcome and patterns of relapse in patients with cutaneous squamous cell carcinoma (SCC) and basal cell carcinoma (BCC) with perineural infiltration (PNI) without clinical or radiologic features, treated with surgery and radiotherapy. Methods and Materials: Between 1991 and 2004, 222 patients with SCC or BCC with PNI on pathologic examination but without clinical or radiologic PNI features were identified. Charts were reviewed retrospectively and relevant data collected. All patients were treated with curative intent; all had radiotherapy, and most had surgery. The primary endpoint was 5-year relapse-free survival from the time of diagnosis. Results: Patients with SCC did significantly worse than those with BCC (5-year relapse-free survival, 78% vs. 91%; p < 0.01). Squamous cell carcinoma with PNI at recurrence did significantly worse than de novo in terms of 5-year local failure (40% vs. 19%; p < 0.01) and regional relapse (29% vs. 5%; p < 0.01). Depth of invasion was also a significant factor. Of the PNI-specific factors for SCC, focal PNI did significantly better than more-extensive PNI, but involved nerve diameter or presence of PNI at the periphery of the tumor were not significant factors. Conclusions: Radiotherapy in conjunction with surgery offers an acceptable outcome for cutaneous SCC and BCC with PNI. This study suggests that focal PNI is not an adverse feature.

    Meibomian gland carcinoma (MGC) and basal cell carcinoma (BCC) are common eyelid carcinomas that exhibit highly dissimilar degrees of proliferation and prognoses. We address here the question of the differential mechanisms between these two eyelid cancers that explain their different outcome. A total of 102 confirmed MGC and 175 diagnosed BCC cases were analyzed. Twenty confirmed MGC and twenty diagnosed BCC cases were collected to determine the telomere length, the presence of senescent cells, and the expression levels of the telomere capping shelterin complex, P53, and the E3 ubiquitin ligase Siah1. Decreased protein levels of the shelterin subunits, shortened telomere length, over-expressed Ki-67, and Bcl2 as well as mutations in P53 were detected both in MGC and BCC. It suggests that the decreased protein levels of the shelterin complex and the shortened telomere length contribute to the tumorigenesis of MGC and BCC. However, several parameters distinguish MGC from BCC samples: (i) the mRNA level of the shelterin subunits decreased in MGC but it increased in BCC; (ii) P53 was more highly mutated in MGC; (iii) Siah1 mRNA was over-expressed in BCC; (iv) BCC samples contain a higher level of senescent cells; (v) Ki-67 and Bcl2 expression were lower in BCC. These results support a model where a preserved P53 checkpoint in BCC leads to cellular senescence and reduced tumor proliferation as compared to MGC. © 2015 UICC.

    Basal cell carcinoma (BCC) is the most common form of skin cancer. To improve the diagnostic accuracy, additional non-invasive methods of making a preliminary diagnosis have been sought. We have implemented an En-Face optical coherence tomography (OCT) for this study in which the dynamic focus was integrated into it. With the dynamic focus scheme, the coherence gate moves synchronously with the peak of confocal gate determined by the confocal interface optics. The transversal resolution is then conserved throughout the depth range and an enhanced signal is returned from all depths. The Basal Cell Carcinoma specimens were obtained from the eyelid a patient. The specimens under went analysis by DF-OCT imaging. We searched for remarkable features that were visualized by OCT and compared these findings with features presented in the histology slices.

    Two white men 57 and 39 years old, and a 47-year-old white woman were seen with slowly developing papulo-nodular lesions of the areola-nipple complex. None of the patients presented with regional lymphadenopathy, history of trauma, or relevant sun-exposure. After excison of the mass, the histologic diagnosis of basal cell carcinoma was made. At two years of follow-up, no recurrence was evident. The low incidence of basal cell carcinoma in this particular site allows us to consider the areola-nipple complex location as unusual. Moreover, literature reports do not suggest that these BCCs have an increased potential for malignancy. The treatment options depend on the extension of the tumor and on the possible involvement of the areola-nipple complex and mammary tissue.

    Vismodegib is a small molecule inhibitor of the Hedgehog signaling pathway that has shown efficacy in the control of locally advanced or metastatic basal cell carcinoma, although proof of its effectiveness in the elimination of aggressive tumors is lacking. We report a case and provide complete histological evidence of a 69-year-old gentleman who presented with a recurrent, infiltrative, and sclerosing (morpheiform) basal cell carcinoma on his left upper lip that was entirely eradicated with a three-month course of vismodegib 150 mg daily. Complete histologic clearance of a tumor in a recurrent, infiltrative, and sclerosing basal cell carcinoma with vismodegib is uncommon.

    In the last couple of decades, photodynamic therapy emerged as a useful tool in the treatment of basal cell carcinoma. However, it still meets limitations due to unfavorable properties of photosensitizers such as poor solubility or lack of selectivity. Dendrimers, polymers widely studied in biomedical field, may play a role as photosensitizer carriers and improve the efficacy of photodynamic treatment. Here, we describe the evaluation of an electrostatic complex of cationic phosphorus dendrimer and rose bengal in such aspects as singlet oxygen production, cellular uptake, and phototoxicity against three basal cell carcinoma cell lines. Rose bengal-cationic dendrimer complex in molar ratio 5:1 was compared to free rose bengal. Obtained results showed that the singlet oxygen production in aqueous medium was significantly higher for the complex than for free rose bengal. The cellular uptake of the complex was 2-7-fold higher compared to a free photosensitizer. Importantly, rose bengal, rose bengal-dendrimer complex, and dendrimer itself showed no dark toxicity against all three cell lines. Moreover, we observed that phototoxicity of the complex was remarkably enhanced presumably due to high cellular uptake. On the basis of the obtained results, we conclude that rose bengal-cationic dendrimer complex has a potential in photodynamic treatment of basal cell carcinoma.

    Full Text Available Jaw cyst-Basal cell nevus-Bifid rib syndrome or Gorlin-Goltz syndrome involves multiple organ system. The most common findings include multiple odontogenic keratocysts in the jaws and basal cell nevus on the skin that have an early age onset. These multiple odontogenic keratocysts warrant aggressive treatment at the earliest because of the damage and possible complications associated with them. Recurrence in these lesions is the most characteristic feature that has to be taken in consideration while explaining the prognosis to the patient. A case report of a child affected with Gorlin-Goltz syndrome diagnosed, treated and followed at this hospital is presented here.

    Vismodegib is a first-in-class agent targeting the hedgehog signaling pathway for treatment of patients with locally advanced basal cell carcinoma (BCC) and metastatic BCC. There have been concerns about the development of squamous cell carcinoma (SCC) in patients treated with this drug. We sought to determine whether treatment with vismodegib is associated with an increase in the risk of cutaneous SCC. In this retrospective cohort study, patients treated with vismodegib as part of phase I and II clinical studies were compared with participants from the University of California, San Francisco, Nonmelanoma Skin Cancer Cohort who received standard therapy for primary BCC. In total, 1675 patients were included in the analysis, and the development of SCC after vismodegib exposure was assessed. The use of vismodegib was not associated with an increased risk of subsequent development of SCC (adjusted hazard ratio, 0.57; 95% confidence interval, 0.28-1.16). Covariates including age, sex, history of previous nonmelanoma skin cancer, and number of visits per year were significantly associated with the development of SCC. A limitation of the study was that a historic control cohort was used as a comparator. Vismodegib was not associated with an increased risk of subsequent SCC when compared with standard surgical treatment of BCC. Copyright © 2017 American Academy of Dermatology, Inc.

    Typical cutaneous basal cell carcinoma (BCC) and squamous cell carcinoma (SCC) are morphologically dissimilar. It is well known, however, that poorly differentiated SCC may assume a basaloid phenotype, complicating the histologic distinction between these 2 neoplasms. Selected immunohistochemical stains have been used in the past to aid in that differential diagnosis. In the current study, additional markers were evaluated to determine whether they would be helpful in that regard. Twenty-nine cases of metatypical (squamoid) BCC (MBCC) and 25 examples of basaloid SCC (BSCC) were studied using the antibodies Ber-EP4 and MOC-31 as well as a plant lectin preparation from Ulex europaeus I (UEA-1). The resulting immunostains were interpreted independently by 3 pathologists, and the results showed that MBCCs demonstrated strong and diffuse staining for Ber-EP4 (25/29) and MOC-31 (29/29). In contrast, BSCCs tended to be only sporadically reactive for both markers (4/25 and 1/25 cases, respectively). Labeling for UEA-1 was observed in almost all BSCCs (24/25), but only 6 of 29 cases of MBCC showed limited, focal staining with that lectin. These data suggest that MOC-31 is a useful marker in the specified differential diagnosis, especially when used together with UEA-1. Copyright © 2015 Elsevier Inc. All rights reserved.

    The number of melanocytic naevi in Caucasians is related to previous exposure to the sun and is a well-documented major risk factor for cutaneous malignant melanoma. Basal cell carcinoma, which is the most common form of skin cancer, has also been shown to be related to exposure to the sun....... To investigate whether the number of common naevi is a risk factor for basal cell carcinoma in Caucasians we performed whole-body counting of naevi > or =2 mm in a Danish case-control study with 145 cases of primary basal cell carcinoma and 119 controls matched on age, gender and place of residence. Naevi were...... recorded according to size and body region and the skin phototype was assessed. There was no correlation between self-reported skin type and the number of naevi. Females with basal cell carcinoma had more naevi than did female controls (median number of naevi: 65 and 32, respectively) while males...

    Hedgehog (Hh) pathway inhibitors such as vismodegib are highly effective for treating basal cell carcinoma (BCC); however, residual tumor cells frequently persist and regenerate the primary tumor upon drug discontinuation. Here, we show that BCCs are organized into two molecularly and functionally distinct compartments. Whereas interior Hh + /Notch + suprabasal cells undergo apoptosis in response to vismodegib, peripheral Hh +++ /Notch - basal cells survive throughout treatment. Inhibiting Notch specifically promotes tumor persistence without causing drug resistance, while activating Notch is sufficient to regress already established lesions. Altogether, these findings suggest that the three-dimensional architecture of BCCs establishes a natural hierarchy of drug response in the tumor and that this hierarchy can be overcome, for better or worse, by modulating Notch.

    2012-02-01

    BACKGROUND: Basal cell carcinomas are the most prevalent of all skin cancers worldwide and form the majority of the surgical workload for most modern cutaneous malignancy centres. Primary surgical removal of basal cell carcinomas remains the gold standard of treatment but, despite almost two centuries of surgical experience, rates of incomplete surgical excision of up to 50% are still reported. The aim of this study was to assess, quantify and perform comparative analysis of the outcomes and predictive factors of consecutive primarily-excised basal cell carcinomas in a tertiary centre over a six-year period. METHODS: Retrospective audit was conducted on all patients who underwent surgical excision of basal cell carcinomas from January 2000 to December 2005. Assessment parameters included patient biographics, tumour management differences and detailed histopathological analysis of tumour margins and subtypes. RESULTS: One thousand eight hundred and thirty two basal cell carcinomas were excised from 1329 patients over the designated time period. Two hundred and fifty one (14%) lesions were incompletely excised with 135 (7.4%) involving the peripheral margin only, 48 (2.6%) the deep margin only and 41 (2.2%) involving both. Nasal location was the most common predictor of incomplete excision. CONCLUSIONS: Overall basal cell carcinomas excision rates compared favourably with international reported standards but attention to a variety of surgical and histological risk factors may improve this further.

    A bibliographic review was conduced on the use of 5-methyl aminolevulinate in dermatology, specifically in the treatment of actinic keratosis, epidermoid carcinoma and basal cell carcinoma. The basic fundamentals of photodynamic therapy are described. The preparation and method of use of photodynamic therapy with 5-methyl aminolevulinate (MAL-PDT) are detailed. The clinical studies that were realized with photodynamic therapy for the treatment of actinic keratosis, epidermoid carcinoma and basal cell carcinoma are mentioned. Different photo-inducible agents and other current therapeutic options of first-line are compared. The MAL-PDT has have the advantage of to present less side effects and the same have been more tolerable than liquid nitrogen and 5 fluorouracil. The MAL-PDT has been considered as an effective option for the treatment of Bowen's disease. Invasive epidermoid carcinoma has existed without evidence to support the routine use of this therapeutic. For superficial basal cell carcinoma, the MAL-PDT has presented a high cure rate and transient and manageable side effects in extensive and multiple lesions. The MAL-PDT has been an effective and safe treatment in patients with basal cell carcinoma, for those with less depth of 2mm. The MAL-PDT could play an important role in the field of prevention with immunosuppressed patients, particularly, those that have required transplant and its immunosuppression has been pharmacological. The use or not of the MAL-PDT, should be evaluated individually for each patient and to have suitable characteristics for each disease that was cited in this review. The photodynamic therapy with 5-methyl aminolevulinate has been a therapeutic modality of considerable economy, however, it should be evaluated in the context of number of inquiries and side effects that have offered other therapeutic modalities [es

    Full Text Available Purpose: To describe a reconstructive technique of the superior eyelid with flaps and free grafts after excision of a basal cell carcinoma. Methods: Single case report of a 79-year-old woman who presented to our hospital with a basal cell carcinoma of the upper eyelid margin with initial erosion. Results: A large and full-thickness excision of the carcinoma was performed. The reconstruction technique should be customized to the individual patient. In this case, the use of a full-thickness tarsal graft from the contralateral upper eyelid, followed by an ipsilateral bipedicled flap and finally by a skin graft, was an effective surgical procedure, performed in one stage, without complications, and with good functional and esthetic results. Conclusions: Malignant neoplasms represent the leading cause of plastic reconstruction in the orbital region. Surgical techniques must be individualized for each patient and for each type of carcinoma. Reconstructive techniques with free grafts and flaps yield excellent results in the orbital region, particularly when some advice and a few fundamental rules are followed, namely accurate hemostasis of the receiving graft bed by moderate use of diathermy, careful suturing of the edges, and application of a compressive dressing for at least 4 days. Postoperative complications are very rare.

    Full Text Available The results of evaluation of the efficiency of photodynamic therapy with photosensitizer radachlorine for basal cell carcinoma are represented. The study included patients with primary and recurrent cancer, solitary and multiple foci of different histological subtypes. All tumors corresponded stages T1-2N0M0. The radachlorine solution was injected into pathological focus at dose of 1.75-3.50 mg/ cm2 of tumor 15 min before the onset of irradiation (wavelength of 662 nm, light dose of 300 J/cm2. The evaluation of efficiency by means of short-term and long-term outcomes was performed on the basis of clinical and cytological data. According to shortterm outcomes evaluation, the total tumor regression was in 43 (95,5% patients for 47 (95,9% tumors. The partial regression was achieved in 2 (4,5% patients, who subsequently had one repeated course of photodynamic therapy with short-term outcome as total tumor regression. All patients with multiple, superficial and nodal forms of basal cell carcinoma had total tumor regression in 100% of cases, with ulcerated form – in 94,4%, with morphea-like form – in 83,3%. During follow-up in subjects, 44 (97,7% patients had 5-year recurrence-free period. The relapse of tumor was detected in 1 (2,3% patient after PDT for primary cancer of nasal ala stage Т2N0M0 of solid and adenoid histological subtype. Thus, photodynamic therapy with intralesional injection of radachlorine showed high efficiency for treating all existent clinical forms and histological subtypes of basal cell carcinoma

    Limited information is available regarding disease awareness and sun protection behaviour in patients previously treated for non-melanoma skin cancer. Using a telephone-administered questionnaire, we investigated these characteristics in 250 patients in the west of Ireland who had undergone excision of basal cell carcinomas between January 2011 and December 2012. Only 28.8% of respondents knew that the lesion they had excised was a BCC and understood that there was a significant chance of developing another similar lesion in the next 3 years. Women and patients under age 65 were significantly better informed about their diagnosis than men (p = 0.021 and 0.000 respectively). The majority of patients (71.2%) knew that the overall effect of UV radiation on the skin was harmful and did employ some form of sun protection (avoid midday sun 72%; stay in shade 74%; wear hat 73.6%; wear sunscreen 72.8%). Females were statistically more likely to exercise better sun-protection behaviour (p = 0.002). While 76.8% of patients undertook some form of outdoor activity every day, only 22.8% wore sunscreen every day. Greater efforts should be made to communicate disease details and sun protection implications associated with basal cell carcinoma, especially to male patients. Improved population specific skin cancer awareness may lead to earlier detection and thus decrease both the patient morbidity and economic burden associated with locally advanced basal cell carcinoma.

    Few data exist on the occurrence of metastatic basal cell carcinoma (mBCC). To identify all cases of mBCC in Denmark over a 14-year period. We searched the Danish National Patient Registry covering all Danish hospitals, the Danish Cancer Registry, the National Pathology Registry and the Causes of Death Registry during the period 1997 to 2010 for potential cases of mBCC registered according to the International classification of diseases ICD-10 and the International Systemized Nomenclature of Medicine (SNOMED). We identified 126,627 patients with a history of primary basal cell carcinoma (BCC) in the registries during the 14-year study period. Using case identifications from the four registries, a total of 170 potential mBCC cases were identified. However, after a pathology review, only five cases could be confirmed, of which three were basosquamous carcinomas. The 14-year cumulative incidence proportion of mBCC was 0.0039% (95% CI 0.0016-0.0083) among individuals with a history of previous BCC (n = 126,627) and 0.0001% (95% CI 0.0000-0.0002) in the general population. MBCC is a rare disease and only a small proportion of potential cases identified in automated clinical databases or registries can be confirmed by pathology and medical record review.

    In this work, a structured methodology is proposed and tested through infrared imaging temperature measurements of a healthy control group to establish expected normality ranges and of basal cell carcinoma patients (a type of skin cancer) previously diagnosed through biopsies of the affected regions. A method of conjugated gradients is proposed to compare measured dimensionless temperature difference values (Δ θ) between two symmetric regions of the patient's body, that takes into account the skin, the surrounding ambient and the individual core temperatures and doing so, the limitation of the results interpretation for different individuals become simple and nonsubjective. The range of normal temperatures in different regions of the body for seven healthy individuals was determined, and admitting that the human skin exhibits a unimodal normal distribution, the normal range for each region was considered to be the mean dimensionless temperature difference plus/minus twice the standard deviation of the measurements (Δθ±2σ) in order to represent 95% of the population. Eleven patients with previously diagnosed basal cell carcinoma through biopsies were examined with the method, which was capable of detecting skin abnormalities in all cases. Therefore, the conjugated gradients method was considered effective in the identification of the basal cell carcinoma through infrared imaging even with the use of a low optical resolution camera (160 × 120 pixels) and a thermal resolution of 0.1 °C. The method could also be used to scan a larger area around the lesion in order to detect the presence of other lesions still not perceptible in the clinical exam. However, it is necessary that a temperature differences mesh-like mapping of the healthy human body skin is produced, so that the comparison of the patient Δ θ could be made with the exact region of such mapping in order to possibly make a more effective diagnosis. Finally, the infrared image analyzed through the

    Full Text Available Giant cell arteritis is a granulomatous vasculitis of large and medium sized arteries manifesting as temporal arteritis and/or polymyalgia rheumatica. The histological assessment of temporal artery biopsies is frequently encountered in anatomical pathology and has important diagnostic consequences in patients clinically suspected of having giant cell arteritis. We present an intriguing case of giant cell arteritis associated with a Basal cell carcinoma and discuss the ongoing controversy pertaining to the association of giant cell arteritis/polymyalgia rheumatica with malignancy.

    Full Text Available Basal cell carcinoma (BCC is the most common cancer among humans, and the standard treatment is surgery. Other modalities are reserved as a second line of treatment. Topical chemotherapy may be used in primary BCC. Systemic chemotherapy has no role in the primary treatment of BCC, although it may be efficacious in metastatic cases. We report the case of a patient with persistent recurrent BCC following multiple surgeries and radiotherapy, who achieved a dramatic response with a cisplatinand 5-flourouracil chemotherapy regimen.

    In a 86-year-old woman, basal cell carcinoma (BCC) arose on the skin with chronic radiation dermatitis. She, at the age of 46, received irradiation to the abdomen for cancer of the uterine cervix. Radiation source and dose were unknown. A verrucous eruption appeared on the irradiated field of the right abdomen, and gradually expanded. Histological examination showed that proliferation of tumor cells with adenoid and cystose structure extended to the epidermis. Electron microscopic study showed both clear and dark tumor cells, although dark cells were few in number. A review of the literature showed that BCC arising on the skin with chronic radiation dermatitis is uncommon in Japan. (Namekawa, K.)

    Mohs' micrographic surgery (MMS) is an effective means of margin control in the management of periocular basal cell carcinomas (BCC). We describe three cases of recurrent BCC that presented with progressive eyelid contracture after MMS. They illustrate high-risk factors for recurrence, namely large tumor size, medial canthal location, previous treatment, and aggressive histological features. Careful long-term surveillance with serial photography may identify early eyelid contracture and thus assist in the detection of recurrent BCC after MMS and improve patient outcome.

    Full Text Available ABSTRACT Purpose The vast majority of urothelial carcinomas infiltrating the bladder are consistent with high-grade tumors that can be easily recognized as malignant in needle prostatic biopsies. In contrast, the histological changes of low-grade urothelial carcinomas in this kind of biopsy have not been studied. Materials and Methods We describe the clinicopathologic features of two patients with low-grade bladder carcinomas infiltrating the prostate. They reported dysuria and hematuria. Both had a slight elevation of the prostate specific antigen and induration of the prostatic lobes. Needle biopsies were performed. At endoscopy bladder tumors were found in both cases. Results Both biopsies showed nests of basophilic cells and cells with perinuclear clearing and slight atypia infiltrating acini and small prostatic ducts. The stroma exhibited extensive desmoplasia and chronic inflammation. The original diagnosis was basal cell hyperplasia and transitional metaplasia. The bladder tumors also showed low-grade urothelial carcinoma. In one case, the neoplasm infiltrated the lamina propria, and in another, the muscle layer. In both, a transurethral resection was performed for obstructive urinary symptoms. The neoplasms were positive for high molecular weight keratin (34BetaE12 and thrombomodulin. No metastases were found in either of the patients, and one of them has survived for five years. Conclusions The diagnosis of low-grade urothelial carcinoma in prostate needle biopsies is difficult and may simulate benign prostate lesions including basal cell hyperplasia and urothelial metaplasia. It is crucial to recognize low-grade urothelial carcinoma in needle biopsies because only an early diagnosis and aggressive treatment can improve the prognosis for these patients.

    Three members of a family, father, daughter, and son, with the basal cell nevus syndrome are presented. A very unusual manifestation of widespread cyst-like osteolytic lesions in all the tubular bones was observed in the father, together with osteoblastic spotty 'osteopoikilotic' lesions in the skull and the mandible of the same patient. Cyst-like osteolytic lesions have been described previously in this syndrome, mainly in the phalanges. We believe that such lesions can occur in any bone. (orig.)

    Basal cell carcinoma (BCC) is the most common type of skin cancer, which is highly damaging to the skin at its advanced stages and causes huge costs on the healthcare system. However, most types of BCC are easily curable if detected at early stage. Due to limited access to dermatologists and expert physicians, non-invasive computer-aided diagnosis is a viable option for skin cancer screening. A clinical biomarker of cancerous tumors is increased vascularization and excess blood flow. In this paper, we present a computer-aided technique to differentiate cancerous skin tumors from benign lesions based on vascular characteristics of the lesions. Dermoscopy image of the lesion is first decomposed using independent component analysis of the RGB channels to derive melanin and hemoglobin maps. A novel set of clinically inspired features and ratiometric measurements are then extracted from each map to characterize the vascular properties and blood content of the lesion. The feature set is then fed into a random forest classifier. Over a dataset of 664 skin lesions, the proposed method achieved an area under ROC curve of 0.832 in a 10-fold cross validation for differentiating basal cell carcinomas from benign lesions.

    Basal cell carcinoma (BCC) is the most common cancer in the US population affecting approximately 2.8 million people per year. Basal cell carcinomas are usually slow-growing and rarely metastasize, but they do cause localized tissue destruction, compromised function, and cosmetic disfigurement. To provide clinicians with guidelines for the management of BCC based on evidence from a comprehensive literature review, and consensus among the authors. An extensive review of the medical literature was conducted to evaluate the optimal treatment methods for cutaneous BCC, taking into consideration cure rates, recurrence rates, aesthetic and functional outcomes, and cost-effectiveness of the procedures. Surgical approaches provide the best outcomes for BCCs. Mohs micrographic surgery provides the highest cure rates while maximizing tissue preservation, maintenance of function, and cosmesis. Mohs micrographic surgery is an efficient and cost-effective procedure and remains the treatment of choice for high-risk BCCs and for those in cosmetically sensitive locations. Nonsurgical modalities may be used for low-risk BCCs when surgery is contraindicated or impractical, but the cure rates are lower.

However, aberrant Hh signaling activation has been implicated in the development and promotion of certain types of cancer, including basal cell carcinoma (BCC, medulloblastoma, and gastrointestinal cancers. In 2015, the US Food and Drug Administration (FDA approved sonidegib, a smoothened (SMO antagonist, for treatment of advanced BCC (aBCC after a successful Phase II clinical trial. Sonidegib, also named Odomzo, is the second Hh signaling inhibitor approved by the FDA to treat BCCs following approval of the first SMO antagonist vismodegib in 2012. What are the major features of sonidegib (mechanism of action; metabolic profiles, clinical efficacy, safety, and tolerability profiles? Will the sonidegib experience help other clinical trials using Hh signaling inhibitors in the future? In this review, we will summarize current understanding of BCCs and Hh signaling. We will focus on sonidegib and its use in the clinic, and we will discuss ways to improve its clinical application in cancer therapeutics.

    Full Text Available A controlled trial was performed with the purpose of investigating which factors could be considered of significant risk for the development of basal cell carcinoma. A total of 259 cases of basal cell carcinoma diagnosed from July 1991 to July 1992 were compared with 518 controls matched for age and sex. All subjects in both groups were white. Protocol data were submitted to statistical analysis by the chi-square test and by multiple conditional logistic regression analysis and the following conclusions were reached: 1 light skin color (types I and II of the Fitzpatrick classification, odds ratio of 2.8; outdoor work under constant sunlight, odds ratio of 5.0; the presence of actinic lesions due to exposure to the sun, odds ratio of 4.9, are risk factors perse. 2 Type III skin in the Fitzpatrick classification only represents a risk factor when the patient reports a history of intense sunburns, but not in the absence of such a history. 3 Sunburns per se do not represent a risk factor althorig the point made in item 2 of these conclusions is valid. 4 Other suspected risk factors whose significance was not confirmed by multiple conditioned logistic regression analysis were: residence in rural areas, light eyes and blond hair color, extent of the awareness of the "sun x skin cancer" relationship, familial occurrence of skin cancer, excessive exposure to the sun, and freckles appearing in childhood.

    Monoclonal antibodies that block immune regulatory proteins such as programmed death-1 (PD-1) have demonstrated remarkable efficacy in controlling the growth of multiple tumor types. Unresectable or metastatic basal cell carcinoma, however, has largely gone untested. Because PD-Ligand-1 (PD-L1) expression in other tumor types has been associated with response to anti-PD-1, we investigated the expression of PD-L1 and its association with PD-1 expression in the basal cell carcinoma tumor microenvironment. Among 40 basal cell carcinoma specimens, 9/40 (22%) demonstrated PD-L1 expression on tumor cells, and 33/40 (82%) demonstrated PD-L1 expression on tumor-infiltrating lymphocytes and associated macrophages. PD-L1 was observed in close geographic association to PD-1+ tumor infiltrating lymphocytes. Additionally, we present, here, the first report of an objective anti-tumor response to pembrolizumab (anti-PD-1) in a patient with metastatic PD-L1 (+) basal cell carcinoma, whose disease had previously progressed through hedgehog pathway-directed therapy. The patient remains in a partial response 14 months after initiation of therapy. Taken together, our findings provide a rationale for testing anti-PD-1 therapy in patients with advanced basal cell carcinoma, either as initial treatment or after acquired resistance to hedgehog pathway inhibition.

    Surgery is the golden standard for treating basal cell carcinomas. In case of positive tumor margins or recurrent disease, postoperative adjuvant or salvaging therapy is suggested to achieve good local control. To retrospectively report on local control and toxicity of postoperative radiotherapy by means of orthovoltage X-rays for residual or recurrent basal cell carcinoma after surgery in the head and neck area. Sixty-six surgically resected residual or recurrent basal cell carcinomas of the head and neck region were irradiated postoperatively by means of orthovoltage X-rays at the Netherlands Cancer Institute between January 2000 and February 2015. After a median follow-up duration of 30.5 months, only 5 recurrences were reported. The 5-year local control rates at 1, 3, and 5 years were 100%, 87%, and 87%, respectively. The 5-year local control rate was 92% for immediate postoperative radiotherapy of incompletely resected basal cell carcinomas, 90% for recurrences after 1 previously performed excision, and 71% for multiple recurrences, namely, a history of more than 1 excision ( P = .437). Acute toxicity healed spontaneously within 3 months. Late toxicities were mild. Radiotherapy by means of orthovoltage X-ray is an excellent alternative for re-excision in case of incompletely resected or recurrent basal cell carcinomas that are at risk of serious functional and cosmetic impairments after re-excision, with a 5-year local control rate of 87% and a low toxicity profile.

    2013-11-01

    This paper presents a novel method for basal-cell carcinoma detection, which combines state-of-the-art methods for unsupervised feature learning (UFL) and bag of features (BOF) representation. BOF, which is a form of representation learning, has shown a good performance in automatic histopathology image classi cation. In BOF, patches are usually represented using descriptors such as SIFT and DCT. We propose to use UFL to learn the patch representation itself. This is accomplished by applying a topographic UFL method (T-RICA), which automatically learns visual invariance properties of color, scale and rotation from an image collection. These learned features also reveals these visual properties associated to cancerous and healthy tissues and improves carcinoma detection results by 7% with respect to traditional autoencoders, and 6% with respect to standard DCT representations obtaining in average 92% in terms of F-score and 93% of balanced accuracy.

    Full Text Available Halo phenomenon of nevus may be observed as a circular reaction, although it is unusual around tumors. A 29-year-old woman presented with a pigmented lesion on the cheek since three years. She noted whitening of the skin around the lesion almost after a year following its appearance. Dermatologic examination revealed a pigmented nodular lesion with a hypopigmented halo on the left infraorbital region. The clinical impression was halo nevus, whereas basal cell carcinoma (BCC was considered in dermatoscopic differential diagnosis. The diagnosis was infiltrative-type BCC histopathologically. The persistence of a perilesional halo around an enlarging pigmented lesion should be carefully examined with accompanying dermatoscopic findings even in young patients for early diagnosis of tumoral lesions.

    2011-01-01

    Full Text Available Due to intensified research over the past decade, the Hedgehog (HH pathway has been identified as a pivotal defect implicated in roughly 25% of all cancers. As one of the most frequent cancer worldwide, the development of Basal cell carcinoma (BCC due to activation of the HH pathway has been convincingly demonstrated. Thus the discovery of this central tumor-promoting signalling pathway has not only revolutionized the understanding of BCC carcinogenesis but has also enabled the development of a completely novel therapeutic approach. Targeting just a few of several potential mutations, HH inhibitors such as GDC-0449 achieved already the first promising results in metastatic or locally advanced BCC. This paper summarizes the current understanding of BCC carcinogenesis and describes the current “mechanism-based” therapeutic strategies.

    The hedgehog (Hh) signaling pathway has been identified as important to normal embryonic development in living organisms and it is implicated in processes including cell proliferation, differentiation and tissue patterning. Aberrant Hh pathway has been involved in the pathogenesis and chemotherapy resistance of different solid and hematologic malignancies. Basal cell carcinoma (BCC) and medulloblastoma are two well-recognized cancers with mutations in components of the Hh pathway. Vismodegib has recently approved as the first inhibitor of one of the components of the Hh pathway (smoothened). This review attempts to provide current data on the molecular pathways involved in the development of BCC and the therapeutic options available for the treatment of locally advanced and metastatic BCC, and the new targeted therapies in development.

    Basal cell carcinoma (BCC) belongs to the group of non-melanoma skin tumors and is the most common tumor in the western world. BCC arises due to mutations in the tumor suppressor gene Patched1 (Ptch). Analysis of the conditional Ptch knockout mouse model for BCC reveals that macrophages and dendritic cells (DC) of the skin play an important role in BCC growth restraining processes. This is based on the observation that a clodronate-liposome mediated depletion of these cells in the tumor-bearing skin results in significant BCC enlargement. The depletion of these cells does not modulate Ki67 or K10 expression, but is accompanied by a decrease in collagen-producing cells in the tumor stroma. Together, the data suggest that cutaneous macrophages and DC in the tumor microenvironment exert an antitumor effect on BCC.

    The urgency of BCC study affecting maxillofacial area and neck is not only caused by high prevalence of this disease, but also insufficient efficiency of existing treatment methods which lead to full or partial recovery only in 60-80% of cases. We analyzed the results of 198 BCC cases cryosurgical treatment. 33 (16,6%) patients showed continued tumor growth. It has been hypothesized that the behavior and character of microcirculation changes during patient's testing have to correlate with damaging rate of tumors that will allow to develop indications for surgical treatment with local destruction - cryosurgery or cryolaser treatment. We have tested the new group of 33 patients with primary and recurrence types of basal cell carcinoma (BCC) by means of Laser Doppler Flowmetry, Tissues Reflectance Oximetry, Laser Fluorescence Diagnostics before operation. It was shown that the microcirculatory data indicates the presence of cryoresistance.

    Basal cell carcinoma (BCC) of the nipple-areola complex is very rare. Only 24 cases were reported in the literature and 17 (70.8%) of these cases arose in men. Most of the cases were treated with simple excision. We report on a case of BCC of the nipple-areola complex in a 46-year-old woman, treated with partial mastectomy. Metastasis to the axillary lymph nodes had been noted in 3 (12.5%) of the 24 reported cases of BCC of the nipple-areola complex. Thus, we applied the concept of the sentinel lymph node to detect possible metastases of axillary lymph nodes, letting us avoid the unnecessary axillary lymph node dissection and possible future morbidity.

    BACKGROUND: Studies have shown that daylight-photodynamic therapy (PDT) is an effective treatment of actinic keratoses, nearly pain free and more convenient for both the clinics and patients. Treatment of basal cell carcinomas (BCCs) is another main indication for PDT. OBJECTIVES: The aim...... of this open, uncontrolled, prospective explorative study was to evaluate the efficacy of daylight-PDT for BCCs. METHODS: Twenty-one patients with a total of 32 BCCs located in the face, scalp, chest, back and lower leg received one cycle of daylight-methyl aminolevulinate (MAL)-PDT, consisting of two...... treatments 1 week apart. After sunscreen application and lesion preparation, MAL was applied and patients exposed themselves to daylight for 2½ h. Daylight exposure was monitored with a wrist-borne dosimeter. RESULTS: At 3-month follow-up, complete response was seen in 30 lesions (94%) and in 19 patients (90...

    We investigated in detail the dermoscopic and histopathological findings in a case of a superficial type of multiple basal cell carcinomas (BCCs). These multiple lesions (occurring in the chest, neck, and back) showed three different findings, respectively. Dermoscopy of the erythematous and brown-colored patch on the anterior chest showed spoke wheel areas, and the histopathological cross-section revealed vertical spoke wheel structures. In the black- and brown-colored patch at the neck, the dermatoscopy showed a maple leaf-like structure, which was in accordance with the strengthening of the histological lateral connection of the lesion. The brown-colored patch of the lateral back histologically showed irregularly enlarged spoke wheel-like areas with peripheral increased melanin pigments, which correlated with the dark black color of dermoscopic maple leaf-like areas. The vertical spoke wheel areas by dermatoscopy revealed a horizontal spoke wheel structure by histopathology

    Full Text Available Seborrheic keratoses (SKs are common epidermal tumors composed of benign keratinocytes. Malignant skin tumors including basal cell carcinoma (BCC rarely arise within SKs. We report a rare case of an 82-year-old man with nodulocystic BCC that appeared at the center of a scaly hyperpigmented SK that had been presented for more than 10 years. It was histologically confirmed that CK19-positive BCC arose directly from the wall of the pseudohorn cyst, a part of the SK. Nodular and/or cystic BCC also rarely arise within SKs while the most common histologic type of BCC within SKs is the superficial type. Careful observation of SKs is important even though it is rarely a background condition for malignant transformation.

    Full Text Available PURPOSE: To review the role of Mustarde’s flap for post basal cell carcinoma excision lower eyelid reconstruction , its clinical outcomes and complications. METHODS: The Mustarde’s rotational cheek flap has been used to reconstruct the lower eyelids of 16 patients from 2008 to 2015 in proven cases of bcc. RESULT S: Mustarde’s flaps have very high functionally as well as cosmetic acceptability with minimum patient morbidity. The most frequent complications were downward contraction and sagging of the flap and ectropion of the lid margin. To prevent them, the zygomatico - cheek flap must be carefully designed, rotated, and sutured as high as possible so that immediately postoperatively, t he palpebral fissure is only a narrow slit.

    Previous epidemiological studies of overall alcohol intake and basal cell carcinoma (BCC) are inconsistent, with some evidence for differences by type of alcoholic beverage. While alcohol may enhance the carcinogenicity of ultraviolet (UV) radiation, this has not been evaluated in existing epidemiological studies. To evaluate alcohol intake in relation to early-onset BCC, and explore potential interactions with UV exposure. Basal cell carcinoma cases (n = 380) and controls with benign skin conditions (n = 390) under 40 years of age were identified through Yale Dermatopathology. Participants provided information on lifetime alcohol intake, including type of beverage, during an in-person interview. Self-reported data on indoor tanning and outdoor sunbathing were used to categorize UV exposure. We calculated odds ratios (OR) and 95% confidence intervals (CIs) using unconditional multivariate logistic regression in the full sample and in women only. There was no statistically significant association between lifetime alcohol intake and early-onset BCC overall [above median intake vs. no regular alcohol intake (OR 1·10, 95% CI 0·69-1·73)] or in women only (OR 1·21, 95% CI 0·73-2·01). Similarly, intake of red wine, white wine, beer or spirits and mixed drinks was not associated with early-onset BCC. In exploratory analyses, we saw limited evidence for an interaction (P(interaction) = 0·003), with highest risk for high alcohol and high UV exposures, especially in women, but subgroup risk estimates had wide and overlapping CIs. Overall, we did not observe any clear association between lifetime alcohol intake and early-onset BCC. © 2014 British Association of Dermatologists.

    Full Text Available Abstract Background The relationship between anthropometric indices and risk of basal cell carcinoma (BCC is largely unknown. We aimed to examine the association between anthropometric measures and development of BCC and to demonstrate whether adherence to World Health Organisation guidelines for body mass index, waist circumference, and waist/hip ratio was associated with risk of BCC, independent of sun exposure. Methods Study participants were participants in a community-based skin cancer prevention trial in Nambour, a town in southeast Queensland (latitude 26°S. In 1992, height, weight, and waist and hip circumferences were measured for all 1621 participants and weight was remeasured at the end of the trial in 1996. Prevalence proportion ratios were calculated using a log-binomial model to estimate the risk of BCC prior to or prevalent in 1992, while Poisson regression with robust error variances was used to estimate the relative risk of BCC during the follow-up period. Results At baseline, 94 participants had a current BCC, and 202 had a history of BCC. During the 5-year follow-up period, 179 participants developed one or more new BCCs. We found no significant association between any of the anthropometric measures or indices and risk of BCC after controlling for potential confounding factors including sun exposure. There was a suggestion that short-term weight gain may increase the risk of developing BCC for women only. Conclusion Adherence to World Health Organisation guidelines for body mass index, waist circumference and waist/hip ratio is not significantly associated with occurrence of basal cell carcinomas of the skin.

    We analyze the case of a patient with left periorbital infiltrating basal cell carcinoma treated with surgical excision in October 2010. Surgery included orbital exenteration and reconstruction using skin graft and radiotherapy. In May 2013 a MR imaging showed a mass in the left orbital fossa, suggesting a recurrence in the graft. A basal cell carcinoma recurrence with perineural invasion was confirmed in the biopsy. On (18)F-FDG PET/CT performed, a hypermetabolic activity was observed in the left periorbital area with extension to surrounding sinus and bones. The use of (18)F-FDG PET/CT in patients with advanced basal cell carcinoma has not been fully explored due to the rarity of this entity. This case demonstrates the usefulness of this technique to determine the extent of non-melanocytic recurrent skin tumors, and its value in the staging and treatment control, supporting the incorporation of (18)F-FDG PET/CT in the management of advanced basal cell carcinoma.

    Basal-cell carcinoma is the most common form of skin cancer and its incidence is increasing worldwide. We aimed to assess the effectiveness of imiquimod cream versus surgical excision in patients with low-risk basal-cell carcinoma. We did a multicentre, parallel-group, pragmatic, non-inferiority, randomised controlled trial at 12 centres in the UK, in which patients were recruited between June 19, 2003, and Feb 22, 2007, with 3 year follow-up from June 26, 2006, to May 26, 2010. Participants of any age were eligible if they had histologically confirmed primary nodular or superficial basal-cell carcinoma at low-risk sites. We excluded patients with morphoeic or recurrent basal-cell carcinoma and those with Gorlin syndrome. Participants were randomly assigned (1:1) via computer-generated blocked randomisation, stratified by centre and tumour type, to receive either imiquimod 5% cream once daily for 6 weeks (superficial) or 12 weeks (nodular), or surgical excision with a 4 mm margin. The randomisation sequence was concealed from study investigators. Because of the nature of the interventions, masking of participants was not possible and masking of outcome assessors was only partly possible. The trial statistician was masked to allocation until all analyses had been done. The primary outcome was the proportion of participants with clinical success, defined as absence of initial treatment failure or signs of recurrence at 3 years from start of treatment. We used a prespecified non-inferiority margin of a relative risk (RR) of 0.87. Analysis was by a modified intention-to-treat population and per protocol. This study is registered as an International Standard Randomised Controlled Trial (ISRCTN48755084), and with ClinicalTrials.gov, number NCT00066872. 501 participants were randomly assigned to the imiquimod group (n=254) or the surgical excision group (n=247). At year 3, 401 (80%) patients were included in the modified intention-to-treat group. At 3 years, 178 (84%) of

    Basal Cell Carcinoma (BCC) is one of the most common skin cancers in the world and that use to lifestyle, increasing chemical pollutions, environmental factors and poor nutrition. The most important cause of this cancer is oxidative stress and free radicals so antioxidant activities for the body are so important. The aim of this study was to determine the variation of zinc and (Malondialdehyde) MDA in BCC patients. This study has been performed on case and control patients from 2013 to 2014. The samples were collected from cell carcinoma patients at Razi Hospital in Tehran, Iran. We evaluated the level of zinc with the use of Atomic Absorption Spectroscopy (AAS) method. Besides, we evaluated MDA with colorimetric assay. The concentration of MDA was significantly higher in case group in comparison to control group ( P =0.001). In addition, case group had lower concentration of zinc than the control group ( P =0.000). There was no correlation between MDA and body mass index (BMI) and between zinc and BMI. All the patients with BCC showed a significant MDA serum in comparison with control group. However, significant decrease in zinc serum of the patients was seen that is because of consuming zinc during oxidative stress process so topical use of zinc in the form of 2+ ions could be effective on antioxidant protection against the sun UV radiation.

  18. Expression of drebrin, an actin binding protein, in basal cell carcinoma, trichoblastoma and trichoepithelioma.

    Drebrin, an F-actin binding protein, is known to play important roles in cell migration, synaptogenesis and neural plasticity. Although drebrin was long thought to be specific for neuronal cells, its expression has recently been reported in non-neuronal cells. As for skin-derived cells, drebrin was shown to be enriched at adhering junctions (AJs) in cultured primary keratinocytes and also be highly expressed in basal cell carcinoma (BCC) cells. Since BCC and two types of benign neoplasm, trichoblastoma and trichoepithelioma, are considered to derive from the same origin, follicular germinative cells, it is sometimes difficult to morphologically distinguish BCC from trichoblastoma and trichoepithelioma. In this study, we performed immunohistochemical staining of drebrin in BCC, trichoblastoma and trichoepithelioma, to examine whether drebrin could serve as a biomarker for BCC diagnosis. In western blotting, drebrin was detected highly and moderately in the lysates from a squamous cell carcinoma cell line, DJM-1, and normal human epidermis, respectively. In immunofluorescence analyses, drebrin was colocalized with markers of AJs and tight junctions in DJM-1 cells and detected at cell-cell junction areas of human normal epidermis tissue. We then examined the distribution patterns of drebrin in BCC, trichoblastoma and trichoepithelioma. In BCC tissues, intense and homogeneous drebrin expression was observed mainly at tumor cell-cell boundaries. In contrast, drebrin was stained only weakly and non-homogeneously in trichoblastoma and trichoepthelioma tissue samples. For differential diagnosis of BCC, drebrin may be a novel and useful marker.

    Full Text Available Abstract Background The early detection of skin cancer may highly increase the chances of its healing. One of the non-invasive methods of such detection based on the Oblique- Incidence Diffuse Reflectance (OIDR measurements of the reflected diode laser light from the skin. In this research we designed and implemented the OIDR reflectometry measuring system with a 650 nm diode laser source to aid physicians in diagnosing both squamous cell carcinomas (SCC and basal cell carcinomas(BCC. Method The laser is delivered obliquely to the skin surface by an optical fiber fitted through a tube holder of CCD camera. The diffused reflected laser light from the skin is captured by the CCD camera and sent to a computer, which is supplied by a specially prepared Matlab program to analyze these images in order to decide in a time whether the lesion is malignant or benign. Fifty cases were diagnosed under supervision of the consultant section of The Governmental Specialized Marjan Teaching Hospital – MOH – Iraq. Result The fifty diagnosed cases by this technique, the results were 90% accurate. Conclusion The method of laser oblique-incidence diffuse reflectance (OIDR combined with using the developed algorithms that have high classification rates may prove useful in the clinic as the process is fast, noninvasive and accurate.

    The tumor suppressor p53 controls DNA repair, cell cycle, apoptosis, autophagy and numerous other cellular processes. Imiquimod (IMQ), a synthetic toll-like receptor (TLR) 7 ligand for the treatment of superficial basal cell carcinoma (BCC), eliminates cancer cells by activating cell-mediated immunity and directly inducing apoptosis and autophagy in cancer cells. To evaluate the role of p53 in IMQ-induced cell death in skin cancer cells. The expression, phosphorylation and subcellular localization of p53 were detected by real-time PCR, luciferase reporter assay, cycloheximide chase analysis, immunoblotting and immunocytochemistry. Using BCC/KMC1 cell line as a model, the upstream signaling of p53 activation was dissected by over-expression of TLR7/8, the addition of ROS scavenger, ATM/ATR inhibitors and pan-caspase inhibitor. The role of p53 in IMQ-induced apoptosis and autophagy was assessed by genetically silencing p53 and evaluated by a DNA content assay, immunoblotting, LC3 puncta detection and acridine orange staining. IMQ induced p53 mRNA expression and protein accumulation, increased Ser15 phosphorylation, promoted nuclear translocation and up-regulated its target genes in skin cancer cells in a TLR7/8-independent manner. In BCC/KMC1 cells, the induction of p53 by IMQ was achieved through increased ROS production to stimulate the ATM/ATR-Chk1/Chk2 axis but was not mediated by inducing DNA damage. The pharmacological inhibition of ATM/ATR significantly suppressed IMQ-induced p53 activation and apoptosis. Silencing of p53 significantly decreased the IMQ-induced caspase cascade activation and apoptosis but enhanced autophagy. Mutant p53 skin cancer cell lines were more resistant to IMQ-induced apoptosis than wildtype p53 skin cancer cell lines. IMQ induced ROS production to stimulate ATM/ATR pathways and contributed to p53-dependent apoptosis in a skin basal cell carcinoma cell line BCC/KMC1.

    1994-01-01

    We have studied the expression of alpha 6 beta 4 integrin, a carcinoma laminin receptor in ten squamous cell carcinomas (SCCs) and ten basal cell carcinomas (BCCs) of the skin in order to examine whether changes in alpha 6 beta 4 integrin expression may be related to invasive and metastatic...... potential. Monoclonal antibodies specific for each subunit were applied on cryosections, using a three step indirect peroxidase technique. In normal epidermis the basal cells expressed both the alpha 6 and the beta 4 subunits, and the expression was polarized against the basement membrane. In SCCs...

    Full Text Available Background. Basal cell carcinoma (BCC is the most prevalent skin cancer. Because of its highly vascular characteristic, it is amendable to treatment with pulse dye laser (PDL. The goal of this study is to determine the safety and efficacy of PDL therapy for mostly facial BCCs. Materials and Methods. Sixteen men and thirteen women (29 total with 39 biopsy-proven BCCs were treated with 1–4 PDL (595 nm therapies at 2–4-week intervals. The treatment parameters included pulse energy of 15 J/cm 2, pulse length of 3 millisecond, with no dynamic cooling, and 7 mm spot size. The age of the patients was 30–90 years (mean 73 years. Response rates were evaluated by the clinical assessments with mean followup of 11 months. Results. Twenty-four patients with thirty-two tumors reached at least three months followup: 24/32 (75% tumors with complete resolution (mean 3 treatment sessions; 5/32 (16% tumors recurred; 3/32 (9% tumors with incomplete responses after four treatments. Minimal side effects and discomfort were experienced by the patients with PDL therapy. Conclusion. PDL is a safe, tolerable, and moderately effective method of treating various BCCs. The ideal niche and standardized settings for PDL treatment of BCCs are yet to be determined.

    Background. Advanced basal cell carcinoma (BCC) is often treated by surgery or X-ray therapy. The consequences of X-ray therapy on the patients health-related quality-of-life (HRQOL) have so far not been described. Objectives. To quantify quality of life in BCC patients before and after X-ray therapy compared with matched healthy controls. Materials. Twenty-five patients (mean age 69) with BCC completed the Dermatology Life Quality Index (DLQI) before and two weeks and three months after X-ray therapy and their results were compared with the DLQI scores for 25 matched controls. Results. Compared to the healthy controls the patients' DLQI score was significantly higher before and 2 weeks after X-ray therapy ( ρ=0.005;ρ=0.000). The patients' DLQI score decreased significantly from baseline to three months after X-ray therapy (ρ=0.024), when it became similar to that of the healthy controls (ρ=0.819). Three months after X-ray therapy eight patients had no skin reactions, 11 had slight atrophy, pigmentation change, and/or some hair loss, four had patch atrophy, moderate telangiectasia, and/or total hair loss. Conclusions. BCC has a negative effect on patients' quality of life. The study shows that HRQOL normalises shortly after X-ray therapy, despite minor skin manifestations.

    Malignant non-basaloid tumors that arise from basal cell adenoma (BCA) are extremely rare. The patient was a 72-year-old Japanese male, who had noticed swelling of the left parotid region 21 years ago. A superficial lobectomy was performed. About 60% of the tumor was made up of cribriform and trabecular tissue composed of basaloid cells, which exhibited mild atypia and nuclear expression of β-catenin. This portion of the tumor was considered to be a BCA. In the other part of the tumor, the proliferation of large eosinophilic atypical cells, most of which formed intraductal structures, was observed. These tumor cells displayed cellular atypia, and some of them formed Roman bridge structures or contributed to intracapsular invasion. Immunohistochemically, these cells were positive for cytokeratin 7, gross cystic disease fluid proten-15 (GCDFP-15), androgen receptor (AR), and mammaglobin (MMG) and exhibited a high Ki-67 labeling index. So, this portion of the tumor was considered to be a salivary duct carcinoma (SDC). The tumor's final diagnosis was SDC ex BCA (intracapsular type), which is extremely rare. GCDFP-15, AR, MMG, and Ki-67 are useful immunohistochemical markers for diagnosing SDC ex BCA. © 2017 The Authors.

    Smoothened antagonists directly target the genetic basis of human basal cell carcinoma (BCC), the most common of all cancers. These drugs inhibit BCC growth, but they are not curative. Although BCC cells are monomorphic, immunofluorescence microscopy reveals a complex hierarchical pattern of growth with inward differentiation along hair follicle lineages. Most BCC cells express the transcription factor KLF4 and are committed to terminal differentiation. A small CD200(+) CD45(-) BCC subpopulation that represents 1.63 ± 1.11% of all BCC cells resides in small clusters at the tumor periphery. By using reproducible in vivo xenograft growth assays, we determined that tumor initiating cell frequencies approximate one per 1.5 million unsorted BCC cells. The CD200(+) CD45(-) BCC subpopulation recreated BCC tumor growth in vivo with typical histological architecture and expression of sonic hedgehog-regulated genes. Reproducible in vivo BCC growth was achieved with as few as 10,000 CD200(+) CD45(-) cells, representing ~1,500-fold enrichment. CD200(-) CD45(-) BCC cells were unable to form tumors. These findings establish a platform to study the effects of Smoothened antagonists on BCC tumor initiating cell and also suggest that currently available anti-CD200 therapy be considered, either as monotherapy or an adjunct to Smoothened antagonists, in the treatment of inoperable BCC.

    Full Text Available Background. For large basal cell carcinomas (BCCs of the head and neck, definitive surgery often requires extensive resection and reconstruction that may result in prolonged recovery and limited cosmesis. Vismodegib, a small-molecule inhibitor of the hedgehog pathway, is approved for advanced and metastatic BCCs. We present a case of advanced BCC treated with combination of vismodegib, radiotherapy, and local excision resulting in excellent response and cosmesis. Case Presentation. A 64-year-old gentleman presented with a 5-year history of a 7 cm enlarging right cheek mass, with extensive vascularization, central ulceration, and skin, soft tissue, and buccal mucosa involvement. Biopsy revealed BCC, nodular type. Up-front surgical option involved a large resection and reconstruction. After multidisciplinary discussion, we recommended and he opted for combined modality of vismodegib, radiotherapy, and local excision. The patient tolerated vismodegib well and his right cheek lesion decreased significantly in size. He was then treated with radiotherapy followed by local excision that revealed only focal residual BCC. Currently, he is without evidence of disease and has excellent cosmesis. Conclusions. We report a case of locally advanced BCC treated with trimodality therapy with vismodegib, radiotherapy, and local excision, resulting in excellent outcome and facial cosmesis, without requiring extensive resection or reconstructive surgery.

    Basal cell carcinoma (BCC) is characterized by frequent loss of PTCH1, leading to constitutive activation of the Hedgehog pathway. Although the requirement for Hedgehog in BCC is well established, the identity of disease-initiating cells and the compartments in which they reside remain controversial. By using several inducible Cre drivers to delete Ptch1 in different cell compartments in mice, we show here that multiple hair follicle stem cell populations readily develop BCC-like tumors. In contrast, stem cells within the interfollicular epidermis do not efficiently form tumors. Notably, we observed that innervated Gli1-expressing progenitors within mechanosensory touch dome epithelia are highly tumorigenic. Sensory nerves activate Hedgehog signaling in normal touch domes, while denervation attenuates touch dome-derived tumors. Together, our studies identify varying tumor susceptibilities among different stem cell populations in the skin, highlight touch dome epithelia as "hot spots" for tumor formation, and implicate cutaneous nerves as mediators of tumorigenesis.

    2014-12-01

    Tumors with similar or identical histopathologic features have been termed basaloid follicular hamartoma (BFH) or infundibulocystic basal cell carcinoma (BCC). BCC typically lacks immunoreactivity with cytokeratin 20 (CK20) and pleckstrin homology-like domain, family A, member 1 protein (PHLDA1). A series of BFH and infundibulocystic BCC were investigated to determine the pattern of CK20 and PHLDA1 labeling in these lesions. Thirty-six samples of BFH (n = 14) and infundibulocystic BCC (n = 22) were collected. CK20 and PHLDA1 staining was performed and evaluated. All the lesions were small (average of 3 mm), well circumscribed, and composed of basaloid to squamoid cells arranged in islands resembling ramifying rootlets with interspersed horn cysts. CK20-positive cells were present in all 36 cases (average, 22/mm(2)), throughout the tumor, including deeper portions, irrespective of original diagnosis. Six of thirty cases (20%; 5 infundibulocystic BCC, 1 BFH) were focally PHLDA1 positive. Findings on hematoxylin and eosin staining and those of CK20 staining in BFH and infundibulocystic BCC were similar, and in most cases were indistinguishable. The CK20 labeling was similar to that of trichoepithelioma. The findings add a degree of support to the argument that BFH and infundibulocystic BCC represent the same lesion and, further, a benign one. © 2014 John Wiley & Sons A/S.

    2015-09-01

    Full Text Available Basal cell carcinoma (BCC is the most common cancer in individuals with fair skin type (I–II and steadily increasing in incidence (70% of skin malignancy. It is locally invasive but metastasis is usually very rare, with an estimated incidence of 0.0028%–0.55%. Conventional therapy is surgery, especially for the H region of the face and infiltrative lesions; in case of inoperable tumors, radiotherapy is a valid option. Recently, topical photodynamic therapy (PDT has become an effective treatment in the management of superficial and small nodular BCC. PDT is a minimally invasive procedure that involves the administration of a photo-sensibilizing agent followed by irradiation at a pre-defined wavelength; this determines the creation of reactive oxygen species that specifically destroy target cells. The only major side effect is pain, reported by some patients during the irradiation. The high cure rate and excellent cosmetic outcome requires considering this possibility for the management of patients with both sporadic and hereditary BCC. In this article, an extensive review of the recent literature was made, in order to clarify the role of PDT as a possible alternative therapeutic option in the treatment of BCC.

    Cutaneous basal cell carcinoma (BCC) is the most common human cancer and its incidence is rising worldwide. Ultraviolet radiation exposure, including tanning bed use, as well as host factors play a role in its development. The majority of cases are treated and cured with local therapies including surgery. Yet, the health care costs of diagnosis and treatment of BCCs in the US is substantial. In the United States, the cost of nonmelanoma skin cancer care in the Medicare population is estimated to be US$426 million per year. While rare, locally advanced BCCs that can no longer be controlled with surgery and/or radiation, and metastatic BCCs do occur and can be associated with significant morbidity and mortality. Vismodegib (GDC-0449), a smoothened inhibitor targeted at the hedgehog pathway, is the first US Food and Drug Association (FDA)-approved agent in the treatment of locally advanced, unresectable, and metastatic BCCs. This class of agents appears to be changing the survival rates in advanced BCC patients, but appropriate patient selection and monitoring are important. Multidisciplinary assessments are essential for the optimal care and management of these patients. For some patients with locally advanced BCC, treatment with a hedgehog inhibitor may eliminate the need for an excessively disfiguring or morbid surgery. PMID:26604681

    We investigate the potential of Raman microspectroscopy (RMS) for automated evaluation of excised skin tissue during Mohs micrographic surgery (MMS). The main aim is to develop an automated method for imaging and diagnosis of basal cell carcinoma (BCC) regions. Selected Raman bands responsible for the largest spectral differences between BCC and normal skin regions and linear discriminant analysis (LDA) are used to build a multivariate supervised classification model. The model is based on 329 Raman spectra measured on skin tissue obtained from 20 patients. BCC is discriminated from healthy tissue with 90+/-9% sensitivity and 85+/-9% specificity in a 70% to 30% split cross-validation algorithm. This multivariate model is then applied on tissue sections from new patients to image tumor regions. The RMS images show excellent correlation with the gold standard of histopathology sections, BCC being detected in all positive sections. We demonstrate the potential of RMS as an automated objective method for tumor evaluation during MMS. The replacement of current histopathology during MMS by a ``generalization'' of the proposed technique may improve the feasibility and efficacy of MMS, leading to a wider use according to clinical need.

    Basal cell carcinoma (BCC) is the most common type of human skin cancer. The traditional diagnostic procedure of BCC is histological examination with haematoxylin and eosin staining of the tissue biopsy. In order to reduce complexity of the diagnosis procedure, a number of noninvasive optical methods have been applied in skin examination, for example, multiphoton tomography (MPT) and fluorescence lifetime imaging microscopy (FLIM). In this study, we explored two-photon optical tomography of human skin specimens using two-photon excited autofluorescence imaging and FLIM. There are a number of naturally endogenous fluorophores in skin sample, such as keratin, melanin, collagen, elastin, flavin and porphyrin. Confocal microscopy was used to obtain structures of the sample. Properties of epidermic and cancer cells were characterized by fluorescence emission spectra, as well as fluorescence lifetime imaging. Our results show that two-photon autofluorescence lifetime imaging can provide accurate optical biopsies with subcellular resolution and is potentially a quantitative optical diagnostic method in skin cancer diagnosis.

    The current guidelines for the management of basal cell carcinoma (BCC) suggest a different therapeutic approach according to histopathologic subtype. Although dermatoscopic and confocal criteria of BCC have been investigated, no specific studies were performed to evaluate the distinct reflectance confocal microscopy (RCM) aspects of BCC subtypes. To define the specific dermatoscopic and confocal criteria for delineating different BCC subtypes. Dermatoscopic and confocal images of histopathologically confirmed BCCs were retrospectively evaluated for the presence of predefined criteria. Frequencies of dermatoscopic and confocal parameters are provided. Univariate and adjusted odds ratios were calculated. Discriminant analyses were performed to define the independent confocal criteria for distinct BCC subtypes. Eighty-eight BCCs were included. Dermatoscopically, superficial BCCs (n=44) were primarily typified by the presence of fine telangiectasia, multiple erosions, leaf-like structures, and revealed cords connected to the epidermis and epidermal streaming upon RCM. Nodular BCCs (n=22) featured the classic dermatoscopic features and well outlined large basaloid islands upon RCM. Infiltrative BCCs (n=22) featured structureless, shiny red areas, fine telangiectasia, and arborizing vessels on dermatoscopy and dark silhouettes upon RCM. The retrospective design. Dermatoscopy and confocal microscopy can reliably classify different BCC subtypes. Copyright © 2014 American Academy of Dermatology, Inc. Published by Elsevier Inc. All rights reserved.

    Basal cell carcinoma (BCC) is the world's leading skin cancer in terms of frequency at the moment and its incidence continues to rise each year, leading to profound negative psychosocial and economic consequences. UV exposure is the most important environmental factor in the development of BCC in genetically predisposed individuals, this being reflected by the anatomical distribution of lesions mainly on sun-exposed skin areas. Early diagnosis and prompt management are of crucial importance in order to prevent local tissue destruction and subsequent disfigurement. Although various noninvasive or minimal invasive techniques have demonstrated their utility in increasing diagnostic accuracy of BCC and progress has been made in its treatment options, recurrent, aggressive, and metastatic variants of BCC still pose significant challenge for the healthcare system. Analysis of gene expression and proteomic profiling of tumor cells and of tumoral microenvironment in various tissues strongly suggests that certain molecules involved in skin cancer pathogenic pathways might represent novel predictive and prognostic biomarkers in BCC.

    Basal cell carcinomas (BCCs) are common malignant skin tumors. Despite having a significant invasion capacity, they metastasize only rarely. Our aim in this study was to detect the expression patterns of the NM23-H1, NDRG1, E-cadherin, RHOGDI2, CD82/KAI1, MKK4, and AKAP12 metastasis suppressor proteins in BCCs. A total of 96 BCC and 10 normal skin samples were included for the immunohistochemical study. Eleven frozen BCC samples were also studied by quantitative real time polymerase chain reaction (qRT-PCR) to detect the gene expression profile. NM23-H1 was strongly and diffusely expressed in all types of BCC. Significant cytoplasmic expression of NDRG1 and E-cadherin was also detected. However, AKAP12 and CD82/KAI1 expression was significantly decreased. The expressions of the other proteins were somewhere between the two extremes. Similarly, qRT-PCR analysis showed down-regulation of AKAP12 and up-regulation of NM23-H1 and NDRG1 in BCC. Morphologically aggressive BCCs showed significantly higher cytoplasmic NDRG1 expression scores and lower CD82/KAI1 scores than non-aggressive BCCs. The relatively preserved levels of NM23-H1, NDRG1, and E-cadherin proteins may have a positive effect on the non-metastasizing features of these tumors. © 2014 The International Society of Dermatology.

    Background: Basal cell carcinoma (BCC) is the most common skin cancer among whites, and several risk factors have been discussed in itsdevelopment and progress. Detection of human papilloma virus (HPV) deoxyribonucleic acid (DNA) BCCs in some studies suggests that the virus may play a role in the pathogenesis of this disease. Several molecular studies showed conflicting reports. Aims: The purpose of this study was to investigate the association between HPV and BCC using polymerase chain reaction (PCR). Materials and Methods: HPV DNA detection was done for 42 paraffin-embedded tissue specimens of BCC and 42 normal skin samples around the lesions by PCR using GP5+/GP6+ primers. Results: HPV DNA was not found in any of the 42 samples of BCC, and only one normal skin sample around the lesions was positive for HPV DNA by PCR. Conclusion: In this study, no statistically significant difference was seen between the presence of HPV DNA in BCC and normal skin around the lesion, and HPV is not likely to have an important role in pathogenesis of BCC.

    2011-01-01

    Basal cell carcinoma (BCC) is the most common neoplasm in the Caucasian population. Only a fraction of BCC exhibits pigmentation. Lack of melanocyte colonization has been suggested to be due to p53-inactivating mutations in the BCC cells interfering with the p53-proopiomelanocortin pathway and the production of alpha melanocyte-stimulating hormone in the tumor. To evaluate this, we determined tumor pigmentation as well as expression of melan-A and of p53 in 49 BCC tissues by means of immunohistochemistry. As expected, we observed a positive relation between tumor pigmentation and melan-A positive intra-tumoral melanocytes. Melanocyte colonization and, to a lesser extent, p53 overexpression showed intraindividual heterogeneity in larger tumors. p53 overexpression, which is indicative of p53 mutations, was not correlated to melanocyte colonization of BCC. Sequencing of exon 5-8 of the p53 gene in selected BCC cases revealed that colonization by melanocytes and BCC pigmentation is neither ablated by p53 mutations nor generally present in BCCs with wild-type p53.

    The number of skin cancer patients, especially patients with basal cell carcinoma (BCC), is rapidly increasing. Resources available at dermato-oncology units have not increased proportionally, which affects the throughput time of patients. To assess the feasibility and safety of implementation of the one-stop-shop concept for the treatment of patients with BCC at a dermato-oncology unit. A pilot study on a one-stop-shop concept for BCC was performed to investigate procedure safety and patient satisfaction. Fresh frozen sections were used to diagnose the tumours, and subsequently treatment with photodynamic therapy or excision was performed on the same day. Time spent in the hospital was measured and questionnaires were used to evaluate patient satisfaction. Sixteen patients, who together had 19 tumours, were included. Diagnoses were made within a mean time of 100 min (range 27-160 min). The mean throughput time was 4 hours and 7 min (range 60-420 min). No complications were observed, and patient satisfaction was high. The one-stop-shop concept for the treatment of skin cancer patients is feasible and efficient for both patients and dermato-oncology units. Further research is necessary to investigate cost-effectiveness when larger patient groups are involved. © 2011 The Authors.

    Full Text Available Background: Histopathology is considered the gold standard for diagnosis of basal cell carcinoma (BCC but is time consuming and needs expertise to make a correct diagnosis. On the other hand, Tzanck test is a simple, easy, inexpensive and rapid test which uses exfoliative cytology to make a diagnosis. Objective: To compare the results of Tzanck test with histopathology in the diagnosis of BCC and to evaluate the diagnostic reliability and accuracy of Tzanck test in BCC. Materials and Method: Twenty-six patients with clinical suspicion of BCC were recruited. Samples for Tzanck test and histopathology were taken and diagnoses made independently. Results of Tzanck test were compared with histopathology. Results: Twenty-three cases were histopathologically proved to be BCC. Tzanck test correlated in 12 cases of BCC and could exclude all three non-BCC lesions. In 11 cases it failed to diagnose BCC. The sensitivity and specificity of Tzanck test were 52.2% and 100%, respectively, and positive and negative predictive values were 100% and 21.4%. Conclusion: Tzanck test can be recommended for initial, rapid evaluation of a clinically diagnosed case of BCC. Under experienced hands, it reliably confirms BCC. The limitation is low negative predictive value. Since it does not give information about subtypes of BCC which is of great value in therapeutic planning, histopathological confirmation is mandatory.

    Basal cell carcinoma (BCC) is the most common skin cancer among Orientals. Data on this malignancy is lacking in Malaysia, prompting a retrospective study to determine the clinical characteristics in the skin clinic, Sarawak General Hospital between 2000 and 2008. Demographic data and clinical features of 64 histopathologically proven BCC from 43 patients were retrieved. Statistical analysis was performed comparing the clinical characteristics based on the region of involvement and gender. The mean age of presentation was 60.9 years. Male to female ratio was 1.05. Majority of the patients were Chinese (44.2%) followed by Malays (32.6%), Bidayuhs (14.0%) and Ibans (6.9%). Nodular BCC accounted for 95.3% of cases while 4.7% were superficial BCC. All the nodular BCC were pigmented. Ulceration was noted in 18%. There were 82.8% of BCC on the head and neck region and 17.2% on the trunk and limb region. BCC on the latter region were larger (mean 35.0 cf. 14.4 mm, p Sarawak were similar to other Asian studies. Additionally, BCC on the trunk and limbs and in men were larger, ulcerative and long standing warranting better efforts for earlier detection.

    Background Basal cell carcinoma (BCC) has a characteristic stroma, but less is known about the dermal characteristics associated with melanoma in situ (MIS) and actinic keratosis (AK). Materials and methods Dermal changes were studied in 301 specimens of AK, BCC and MIS. Subsequently, blinded images of dermal changes from 90 randomly selected cases of those entities were used to assess the predictive value of the dermal changes. Agreement with the final diagnosis was calculated using kappa coefficient (κ). Results Fibromyxoid stroma was present in 82% of BCC cases; fibrous stroma was seen in 25% of BCC, 58% of MIS and 35.6% of AK specimens (p <0.05). A lichenoid inflammatory infiltrate was frequently associated with AK and a perifollicular infiltrate with periadnexal fibrosis with MIS. Blinded evaluation of images of the dermal changes associated with the tumors yielded the correct diagnosis in (54.4, 41.1 and 27.8%; average 41.2%) by the three appraisers. Coefficient of agreement in blinded imaged evaluation with the actual diagnosis was higher in the BCC and MIS compared with AK (κ = 0.37, p = 0.0001; κ = 0.2, p = 0.0005 and κ = −0.06, p = 0.84, respectively). Conclusion Dermal features may be helpful in predicting the correct diagnosis when tumor is not visible. PMID:24117926

    Full Text Available Objective: To study the aggressiveness of basal cell carcinoma (BCC on the mid-face location. Methods: A total of 30 patients were diagnosed using specimen biopsy with hematoxylineosin stain at Moewardi Public Hospital in Surakarta, Central Java, Indonesia. The age, gender distribution, site of the lesion, as well as clinic-pathological appearance were analyzed. Results: There were 30 patients consisting of 46.7% males and 53.3% females with ages ranging from 33 to 91 years old and with the most common occupation, such as farmers (53.6% and housewives (26.7%. Morpheaform subtypes BCC were more frequent than other types. Based on the predilection, most of the BCC were found to be in the mid-face (76.7% and using determined criteria of histopathological examination, the aggressive appearance was 77% and non-aggressive BCC was 23%. The BCC on the mid-face location was more aggressive than the other sites (P < 0.05. Conclusions: BCC is the most common skin tumor in humans with rare metastases, which might cause significant damage due to its local recurrences and aggressiveness. BCC on the mid-face is significantly more aggressive than that on the other predilection sites.

    Background. Few studies have been done that characterize basal cell carcinoma (BCC) in Asians because this tumor is relatively uncommon in this population group. Objective. To characterize BCC in Asians. Methods. We retrospectively examined fifteen patient variables and eight tumor variables of ten Asian patients with BCC and compared these results to those of thirty matched Caucasian controls with BCC. Results. Asians developed their first BCC at an older age than the age of first BCC in Caucasian controls (68.9 years versus 58.3 years; ρ< 0 . 0 5 ). During their lifetime, Asians had fewer BCCs than the number of BCCs in Caucasian controls (1.11 versus 5.41;ρ< 0 . 0 2 ), despite a similar estimated lifetime daily sun exposure (hours/day) for both groups. Compared to BCCs in Caucasian controls, a higher percentage of BCCs in Asians were clinically pigmented (50.0% versus 3.3%; ρ< 0 . 0 1 ). Conclusion. Asians develop BCCs later in life and develop fewer BCCs over their lifetime than Caucasians, despite similar estimated lifetime daily sun exposure. This finding is probably due to skin pigmentation in Asians being more protective of ultraviolet light than skin pigmentation in Caucasians.

  8. Does the peritumoral stroma of basal cell carcinoma recapitulate the follicular connective tissue sheath?

    2011-07-01

    There are compelling embryologic and anatomic relationships within adnexal tumors. However, these are mostly perceived within the epithelial component while the stromal component of the tumors is frequently overlooked. In postnatal skin, nestin is almost exclusively expressed in the perifollicular mesenchyme. This study examines the expression of this neuroepithelial stem cell protein in trichoblastoma/trichoepithelioma and in basal cell carcinoma (BCC), which is increasingly being viewed as follicular in nature. We employed standard immunohistochemical methods with three different antibodies to examine the expression of nestin in 25 BCCs and compared the staining pattern with that of 7 trichoblastomas and 11 trichoepitheliomas. Nestin is expressed in the peritumoral stroma of all tumors examined and is limited to the immediate layer of mesenchymal cells surrounding the tumor epithelium. In BCC, nestin-immunoreactive cells are found as a sheath of thin, spindled fibroblasts, while reactive cells are plump in trichoepitheliomas/trichoblastomas. We postulate that the peritumoral stroma of BCC imitates the perifollicular connective tissue sheath, while in contrast that of trichoepithelioma/trichoblastoma is similar to the papillary and immediate peripapillary follicular mesenchyme. Further functional and animal experimental studies are needed to test this hypothesis. Copyright © 2011 John Wiley & Sons A/S.

    Full Text Available Background: Basal cell carcinoma (BCC is the most common type of skin cancer in humans. Surgery is still the gold standart for treatment of BCCs. However, there are also less-invasive, nonsurgical therapies such as imiquimod cream and intralesional interferon (IFN alpha-2b for the patients who are poor candidates for surgery and who care cosmetic outcomes. Objective: We report 11 BCC cases with various subtypes successfully treated with either imiquimod alone or in combination with interferon alfa-2b. Methods: Patients with various subtypes of histopathologically proven BCCs who were treated with imiquimod or combination of imiquimod and IFN alpha-2b between 2005-2010 years at our outpatient clinic are included in this report. Results: Of 11 patients we reported, only 4 patients (3 infiltrative, 1 solid types recieved intralesional interferon alpha-2b 3 million IU, 3 times a week combined with topical imiquimod. The rest 7 patients recieved only imiquimod 5% cream. All patients were cured with these regimens. Conclusion: Imiquimod is found to be effective not only in superficial, but also infiltrative, solid, and nodular types. Intralesional interferon alpha-2b is also known to be effective in BCCs and it has a synergistic effect when combined with imiquimod.

    Fluorescence confocal microscopy (FCM) is an emerging technology for rapid imaging of excised tissue, without the need for frozen- or fixed-section processing. Basal cell carcinomas (BCCs) can be detected in Mohs excisions although few studies have described the major BCC findings as seen on FCM. To describe the major BCC findings of excised tissue during Mohs surgery and to correlate them with histopathology. Freshly excised tumours and frozen-thawed discarded tissue of BCC during Mohs surgery were analysed by means of FCM. A side-by-side correlation between FCM images and histological sections was performed. The FCM features of overlying skin and adnexal structures were also described. Sixty-four BCC cases were analysed. Distinct BCC types appeared unique in terms of shape and size of tumour islands [bigger in nodular (18/25), smaller and rounded in micronodular (7/7) and tiny cords for infiltrative ones (24/30)] and for the presence of clefting, palisading and increased nucleus/cytoplasm ratio. An excellent correlation was found between FCM and histological findings (Cohen's κ statistics = 0·9). In six cases, the presence of sebaceous glands and intense stroma reaction represented possible confounders. Fluorescence confocal microscopy is a fast and new imaging technique that allows an excellent visualization of skin structures and BCC findings during Mohs surgery. © 2014 British Association of Dermatologists.

    2015-05-01

    Full Text Available Basal cell carcinoma (BCC is the most common cutaneous malignancy among Caucasians. Rare examples of aggressive and neglected BCC have been reported. Here we report a unique case of a neglected BCC with significant jaw involvement. A 50-year-old female, referred by an otorhinologist, presented with a large ulcer on her chin, which was extended to her mandibular vestibule. The ulcer was 9×5.5 cm in size, and tissue destruction, necrosis was observed in the central portion, and the mandibular bone was exposed. On intraoral examination, tooth mobility and severe bone loss were evident. Due to the primary cutaneous origin of the lesion, BCC was considered as preliminary diagnosis. Biopsy was performed and diagnosis of BCC was confirmed. The diseased mandibular bone was resected and reconstructed with a surgical plate. The soft tissue defect was reconstructed with deltopectoral flap. The patient refused secondary stage plastic surgery. Although BCC is not a lethal malignancy, if left untreated and neglected, it can result in severe destruction, disfigurement, and even mortality.

  12. Gene Expression and Proteome Analysis as Sources of Biomarkers in Basal Cell Carcinoma

    Full Text Available Basal cell carcinoma (BCC is the world’s leading skin cancer in terms of frequency at the moment and its incidence continues to rise each year, leading to profound negative psychosocial and economic consequences. UV exposure is the most important environmental factor in the development of BCC in genetically predisposed individuals, this being reflected by the anatomical distribution of lesions mainly on sun-exposed skin areas. Early diagnosis and prompt management are of crucial importance in order to prevent local tissue destruction and subsequent disfigurement. Although various noninvasive or minimal invasive techniques have demonstrated their utility in increasing diagnostic accuracy of BCC and progress has been made in its treatment options, recurrent, aggressive, and metastatic variants of BCC still pose significant challenge for the healthcare system. Analysis of gene expression and proteomic profiling of tumor cells and of tumoral microenvironment in various tissues strongly suggests that certain molecules involved in skin cancer pathogenic pathways might represent novel predictive and prognostic biomarkers in BCC.

    Basal cell carcinomas (BCCs) were obtained from subjects who had been treated with x-ray for tinea capitis at mean age 8 yr (average dose 3.0 Gy) and who have developed multiple (>5) skin cancers 35-40 years later. By allelic loss analysis, 9/10 tumors from 3 patients exhibited loss of heterozygosity (LOH) in one or more microsatellite markers in chromosome location 9q22.3. The xeroderma pigmentosum A (XPA) and PTCH (nevoid BCC syndrome (NBCCS)) genes are located in region 9q22.3, and often LOH in the region means that alleles of both genes are lost. Mutations were found in the undeleted PTCH allele in 2/9 BCCs, which is consistent with the two-allele inactivation model. A similar analysis for the XPA gene showed 5/9 BCCs with probable inactivating mutations. In 1 patient 5/5 cancers and normal blood showed the same 14 base deletion in codon 256-260 indicating this person was an XPA heterozygote. The same 5 cancers exhibited LOH in region 9q22.3 making it likely that 1 allele of both PTCH and XPA were lost. These results suggest how 2 genes could combine to produce an increase in susceptibility to X-ray-induced carcinogenesis in connection with UV as a second exogenous carcinogen (Supported by NIEHS and NCI).

    The clinical distinction between basal cell carcinoma (BCC) and intradermal melanocytic nevus lesions on the face can be difficult, particularly in young patients or patients with multiple nevi. Dermoscopy is a useful tool for analyzing characteristic dermoscopic features of BCC, such as cartwheel structures, maple leaf-like areas, blue-gray nests and dots, and ulceration. It also reveals arborizing telangiectatic vessels and prominent curved vessels, which are typical of BCC, and comma vessels, which are typical of intradermal melanocytic nevi. It is, however, not always easy to distinguish between these 2 conditions, even when dermoscopy is used. We describe 2 facial lesions that posed a clinical and dermoscopic challenge in two 38-year-old patients; confocal microscopy showed separation between tumor nests and stroma and polarized nuclei, which are confocal microscopy features of basal cell carcinoma.

    2009-06-01

    Full Text Available Basal cell carcinoma (BCC is a very common malignant skin tumor that rarely metastatizes, but is often locally aggressive. Several factors, like large size (more than 3 cm, exposure to ultraviolet rays, histological variants, level of infiltration and perineural or perivascular invasion, are associated with a more aggressive clinical course. These morphological features seem to be more determinant in mideface localized BCC, which frequently show a significantly higher recurrence rate. An immunohistochemical profile, characterized by reactivity of tumor cells for p53, Ki67 and alpha-SMA has been associated with a more aggressive behaviour in large BCCs. The aim of this study was to verify if also little (less than 3 cm basal cell carcinomas can express immunohistochemical markers typical for an aggressive behaviour.

    Ex vivo confocal microscopy is a recent imaging technique for the perioperative control of skin tumour margins. Up to date, it has been used in the fluorescence mode and with vertical sections of the specimen margins. The aim of this study was to evaluate its use in the reflectance mode and with a horizontal ('en face') scanning of the surgical specimen in a series of basal cell carcinoma of the eyelid. Prospective consecutive cohort study was performed at the University Hospital of Saint-Etienne, France. Forty-one patients with 42 basal cell carcinoma of the eyelid participated in this study. Basal cell carcinomas were excised with a 2-mm-wide clinically safe margin. The surgical specimens were analysed under ex vivo confocal microscopy in the reflectance mode and with an en face scanning in order to control at a microscopic level if the margins were free from tumour invasion. Histopathogical examination was later performed in order to compare the results. Sensitivity and specificity of ex vivo confocal microscopy for the presence of tumour-free margins. Ex vivo confocal microscopy results were consistent with histopathology in all cases (tumour-free margins in 40 out of 42 samples; sensitivity and specificity of 100%). Ex vivo confocal microscopy in the reflectance mode with an 'en face' scanning can control tumour margins of eyelid basal cell carcinomas and optimize their surgical management. This procedure has the advantage on the fluorescent mode of not needing any contrast agent to examine the samples. © 2016 Royal Australian and New Zealand College of Ophthalmologists.

    To investigate the accuracy of Medical Benefit Schedule (MBS) item numbers to identify treatments for basal cell carcinomas (BCC) and squamous cell carcinomas (SCC). We linked records from QSkin Study participants (n=37,103) to Medicare. We measured the proportion of Medicare claims for primary excision of BCC/SCC that had corresponding claims for histopathology services. In subsets of participants, we estimated the sensitivity and external concordance of MBS item numbers for identifying BCC/SCC diagnoses by comparing against 'gold-standard' histopathology reports. A total of 2,821 (7.6%) participants had 4,830 separate Medicare claims for BCC/SCC excision; almost all (97%) had contemporaneous Medicare claims for histopathology services. Among participants with BCC/SCC confirmed by histology reports, 76% had a corresponding Medicare claim for primary surgical excision of BCC/SCC. External concordance for Medicare claims for primary BCC/SCC excision was 68%, increasing to 97% when diagnoses for intra-epidermal carcinomas and keratoacanthomas were included. MBS item numbers for primary excision of BCC/SCC are reasonably reliable for determining incident cases of keratinocyte skin cancers, but may underestimate incidence by up to 24%. Medicare claims data may have utility in monitoring trends in conditions for which there is no mandatory reporting. © 2015 Public Health Association of Australia.

    2018-04-08

    Objective: To describe the cytologic features of adenoid cystic carcinoma (ADCC) of salivary glands, and to identify distinguishing cytologic features of ADCC and basal cell adenoma (BCA). Methods: A retrospective review of cytology smears of 30 cases of ADCC and 12 cases of BCA of salivary glands were performed. All cases were collected from Beijing Tongren Hospital, Capital Medical University from January 2010 to January 2017. Except for 2 aspirate smears of ADCC, all were touch imprint smears. All cases had further histological confirmation. Results: Neoplastic ductal cells of ADCC were arranged in three-dimensional clusters, sheets and singles. Hyaline globules were found in most cases (20/30, 66.7%). The nuclei were round to oval, showing varying degrees of nuclear atypia. These included (1) the nuclei were hyperchromatic, demonstrating coarse or slightly coarse, irregularly distributed chromatin; (2) the nuclei were slightly large and vary in size; (3) appearance of the nuclei had a different degree of irregularity (often mild). Nucleoli were common seen (21/30, 70.0%), and were prominent in some cases. Mitosis and necrosis were rare. Cytologically, BCA showed cell arrangements and nuclear features overlapped with those of ADCC. The cytologic difference between these two tumors included: (1) the tumor cells presented rarely in singles; (2) hyaline globules were very uncommon (1/12) in BCA; (3) nuclei of BCA were hypochromatic or slightly hyperchromatic, homogeneous and uniform in appearance and size, overall without nuclear atypia and they were smaller and slender then those of ADCC and (4) individual cells of BCA showed relatively abundant cytoplasm. Conclusions: The cytologic features of ADCC and BCA both overlap and different from each other. Most cases can be diagnosed by cytologic examination. The presence of hyaline globules is an important diagnostic clue of ADCC, although not pathognomonic. Nuclear atypia of neoplastic ductal cells is an essential

    Rates of skin cancer, including basal cell carcinoma (BCC), the most common cancer, have been increasing over the past 3 decades. A better understanding of geographic clustering of BCCs can help target screening and prevention efforts. Present a methodology to identify spatial clusters of BCC and identify such clusters in a northern California population. This retrospective study used a BCC registry to determine rates of BCC by census block group, and used spatial scan statistics to identify statistically significant geographic clusters of BCCs, adjusting for age, sex, and socioeconomic status. The study population consisted of white, non-Hispanic members of Kaiser Permanente Northern California during years 2011 and 2012. Statistically significant geographic clusters of BCC as determined by spatial scan statistics. Spatial analysis of 28 408 individuals who received a diagnosis of at least 1 BCC in 2011 or 2012 revealed distinct geographic areas with elevated BCC rates. Among the 14 counties studied, BCC incidence ranged from 661 to 1598 per 100 000 person-years. After adjustment for age, sex, and neighborhood socioeconomic status, a pattern of 5 discrete geographic clusters emerged, with a relative risk ranging from 1.12 (95% CI, 1.03-1.21; P = .006) for a cluster in eastern Sonoma and northern Napa Counties to 1.40 (95% CI, 1.15-1.71; P Costa and west San Joaquin Counties, compared with persons residing outside that cluster. In this study of a northern California population, we identified several geographic clusters with modestly elevated incidence of BCC. Knowledge of geographic clusters can help inform future research on the underlying etiology of the clustering including factors related to the environment, health care access, or other characteristics of the resident population, and can help target screening efforts to areas of highest yield.

    Follow-up of patients after treatment of basal cell carcinoma (BCC) allows for monitoring of recurrence and detection of new tumours, but adds a significant burden to outpatient clinics. At the skin tumour clinic in the dermatology department, the Royal Hospitals, Belfast, all patients are reviewed for 2 years after surgical excision of a low-risk primary BCC. An audit was undertaken to determine the quality of data set recorded relating to prognostic factors for BCCs to determine the rate of recurrence and number of new primary tumours detected and to determine the completeness of follow-up by patients. Patients who had primary BCCs treated by excision were identified from a database held at the clinic. Medical charts were reviewed to determine data recorded about lesions, the number of recurrent BCCs and new tumours detected, and the number of patients completing follow-up. Between January 1999 and December 2000, 114 patients had 121 primary BCCs excised. BCC location and size were recorded in 100% and 35% of cases, respectively. Histological type was stated for morphoeic or multifocal lesions. Two years of follow-up was completed by 53% of patients and 1 year by 78% of patients. The rate of recurrence was low, with 2 BCC recurring within 2 years of excision. The risk of developing a new BCC was 11.6% in the first year and 6.3% in the second year. Follow-up of patients after excision of a low-risk BCC at the clinic has been reduced to 1 year. A proforma has been developed to encourage documentation of prognostic factors.

    Full Text Available Background: Basal cell carcinoma of the nose is common, with a potential of local recurrence and high-risk features. Materials and Methods: We provide a review on anatomy of the nose, tumour surgery and defect closure on the nose. We analysed our own patients with nasal BCC of a 24 months period. Results: We identified 321 patients with nasal BCC. There was a predominance of female patients of 1.2 to 1. The mean age was 74.8 years. Slow Mohs technique was employed for all tumours until 3D tumour-free margins were achieved. That resulted on average in 1.8 ± 0.7 Mohs stages. The most common histologic types were solitary (n = 182, morpheic (79, and micronodular (20, Perineural infiltration was evident in 56 tumours. Primary closure after mobilisation of soft tissue was possible in 105 BCCs. Advancement flaps were used in 91 tumours, rotation flaps in 47, transposition flaps in 34 tumours, and combined procedures in 6 cases. In 36 patients full-thickness skin grafting was performed. In two patients healing by second intention was preferred. Partial flap loss was seen in four patients (1.4%. All of them had significant underlying pathologies. None of the tumours treated showed a relapse during the observation time. However, this is a limitation of the present study since follow-up was on average only 10 months. Conclusions: BCCs of the nose are common. Only 3D-controlled micrographic surgery (Mohs or slow Mohs guarantee a high rate of complete tumour removal and a very low risk of recurrence.

    Skin cancer is the most commonly diagnosed cancer type worldwide, and 80 % of skin cancers are basal cell carcinoma (BCC). The main risk factor for developing BCC is exposure to ultraviolet radiation (UVR), particularly high-dose exposure at a young age. Outdoor workers, particularly farmers, are at high risk of developing BCC. However, studies of BCC in this population are scant. To comprehensively evaluate all cases of BCC of the head and neck region treated during the years 2007-2013 at our hospital in Poland, and to compare the tumour characteristics in farmers to non-farmers. Retrospective analysis of 312 patients treated for head and neck BCC during the study period (2007-2013). Most patients (198 cases; 63 %) were males, with 114 females (37 %). Median age was 73 years (range 32-96 years). The most common tumour location was the nose and cheek (114 pts; 37 %) followed by the auricle (82 pts; 26 %), lips (54 pts; 18 %), scalp (26 pts; 8 %), and eye (36 pts; 12 %). The most common disease stage on presentation was stage T2 (104 pts, 33 %), followed by stage T1 (79 pts; 25 %), stage T3 (89 pts; 28 %), and stage T4 (40 pts; 14 %). By occupation, farmers accounted for 33 % of all patients (102 of 312 pts). The most common tumour localisations in the farmer subgroup were the nose and cheek (50 pts; 49 %; p farmer group were significantly younger than non-farmers (62 vs. 73 years; p Farmers were significantly more likely to present disease recurrence (27 vs. 12 % of cases; p farmers. It is therefore necessary to consider enhancing educational programmes and other preventative measures in this occupational group and to evaluate the effectiveness of such programmes.

    Early diagnosis of non-melanoma skin cancer (NMSC) is potentially possible using optical coherence tomography (OCT) which provides non-invasive, real-time images of skin with micrometre resolution and an imaging depth of up to 2mm. OCT technology for skin imaging has undergone significant developments, improving image quality substantially. The diagnostic accuracy of any method is influenced by continuous technological development making it necessary to regularly re-evaluate methods. The objective of this study is to estimate the diagnostic accuracy of OCT in basal cell carcinomas (BCC) and actinic keratosis (AK) as well as differentiating these lesions from normal skin. A study set consisting of 142 OCT images meeting selection criterea for image quality and diagnosis of AK, BCC and normal skin was presented uniformly to two groups of blinded observers: 5 dermatologists experienced in OCT-image interpretation and 5 dermatologists with no experience in OCT. During the presentation of the study set the observers filled out a standardized questionnaire regarding the OCT diagnosis. Images were captured using a commercially available OCT machine (Vivosight ® , Michelson Diagnostics, UK). Skilled OCT observers were able to diagnose BCC lesions with a sensitivity of 86% to 95% and a specificity of 81% to 98%. Skilled observers with at least one year of OCT-experience showed an overall higher diagnostic accuracy compared to inexperienced observers. The study shows an improved diagnostic accuracy of OCT in differentiating AK and BCC from healthy skin using state-of-the-art technology compared to earlier OCT technology, especially concerning BCC diagnosis.

    Cutaneous basal cell carcinoma (BCC) is the commonest cancer worldwide. BCC is locally invasive and the surrounding stromal microenvironment is pivotal for tumourigenesis. Cancer associated fibroblasts (CAFs) in the microenvironment are essential for tumour growth in a variety of neoplasms but their role in BCC is poorly understood. Material included facial BCC and control skin from the peritumoural area and from the buttocks. With next-generation sequencing (NGS) we compared mRNA expression between BCC and peritumoural skin. qRT-PCR, immunohistochemical and immunofluorescent staining were performed to validate the NGS results and to investigate CAF-related cyto-and chemokines. NGS revealed upregulation of 65 genes in BCC coding for extracellular matrix components pointing at CAF-related matrix remodeling. qRT-PCR showed increased mRNA expression of CAF markers FAP-α, PDGFR-β and prolyl-4-hydroxylase in BCC. Peritumoural skin (but not buttock skin) also exhibited high expression of PDGFR-β and prolyl-4-hydroxylase but not FAP-α. We found a similar pattern for the CAF-associated chemokines CCL17, CCL18, CCL22, CCL25, CXCL12 and IL6 with high expression in BCC and peritumoural skin but absence in buttock skin. Immunofluorescence revealed correlation between FAP-α and PDGFR-β and CXCL12 and CCL17. Matrix remodeling is the most prominent molecular feature of BCC. CAFs are present within BCC stroma and associated with increased expression of chemokines involved in tumour progression and immunosuppression (CXCL12, CCL17). Fibroblasts from chronically sun-exposed skin near tumours show gene expression patterns resembling that of CAFs, indicating that stromal fibroblasts in cancer-free surgical BCC margins exhibit a tumour promoting phenotype.

    Basal cell carcinoma (BCC) can resemble Merkel cell carcinoma (MCC) on histopathological examination and while CK20 is a useful marker in this differential, it is occasionally negative in MCC. CD56, a sensitive marker of neuroendocrine differentiation, is sometimes used to identify MCC, but has been reportedly variably positive in BCC as well. In contrast, CK5/6 consistently labels BCC but is not expressed in neuroendocrine tumors. We evaluated 20 cases of BCC for the pattern of CD56 and cytokeratin 5/6 (CK5/6) staining, hypothesizing that these 2 stains could differentiate BCC from MCC in difficult cases. Seventeen cases of MCC previously stained with CD56 were also examined. All BCCs showed patchy expression of CD56 except for 2 cases, which showed staining of greater than 70% of tumor. CK5/6 was diffusely positive in all cases of BCC. Fifteen of 17 MCCs were diffusely positive for CD56. The difference in the pattern of CD56 expression between MCC and BCC (diffuse vs patchy, respectively) was statistically significant (P < .05). BCC typically shows patchy CD56 expression and diffuse CK5/6 positivity. These 2 markers can be used to distinguish between BCC and MCC in challenging cases. © 2017 John Wiley & Sons A/S.

    Full Text Available The glycome of one of the largest and most exposed human organs, the skin, as well as glycan changes associated with non-melanoma skin cancers have not been studied in detail to date. Skin cancers such as basal cell carcinoma (BCC and squamous cell carcinoma (SCC are among the most frequent types of cancers with rising incidence rates in the aging population. We investigated the healthy human skin N- and O-glycome and its changes associated with BCC and SCC. Matched patient samples were obtained from frozen biopsy and formalin-fixed paraffin-embedded tissue samples for glycomics analyses using two complementary glycomics approaches: porous graphitized carbon nano-liquid chromatography electro spray ionization tandem mass spectrometry and capillary gel electrophoresis with laser induced fluorescence detection. The human skin N-glycome is dominated by complex type N-glycans that exhibit almost similar levels of α2-3 and α2-6 sialylation. Fucose is attached exclusively to the N-glycan core. Core 1 and core 2 type O-glycans carried up to three sialic acid residues. An increase of oligomannose type N-glycans and core 2 type O-glycans was observed in BCC and SCC, while α2-3 sialylation levels were decreased in SCC but not in BCC. Furthermore, glycopeptide analyses provided insights into the glycoprotein candidates possibly associated with the observed N-glycan changes, with glycoproteins associated with binding events being the most frequently identified class.

    Bartoš, Vladimír; Kullová, Milada

    Basal cell carcinoma (BCC) of the skin exhibits a very heterogeneous histomorphology, on the basis of which it is classified into several subtypes and variants. In many cases, however, a definite categorization remains difficult, because BCC may consist of more than one histopathological subtype. There are limited data exploring the characteristics of these mixed BCCs, since they have not been specifically analysed. The aim of this study was to estimate the prevalence of BCCs with mixed histomorphology observed in a set of primary BCCs and to compare their clinicopathological features with a single type BCC subgroup. A total of 911 histologically proven primary BCCs from 697 patients were investigated. Prevalence of single and mixed type BCCs was 64.9 % and 35.1 %, respectively. In mixed type BCC subgroup, a very heterogeneous histomorphology was found comprising a mixture of two to four different subtypes in various proportions. The most frequent combinations included nodular-infiltrative, superficial-nodular, nodular-trichoepithelial and nodular-micronodular subtype. Comparative analysis of the two given subgroups showed that mixed type BCCs were significantly more frequently localized on the extrafacial regions of the head (30.0 % vs. 20.0 %, p = 0.02) and less often on the face (37.2 % vs. 45.2 %, p = 0.03). There were not convincing differences in the occurrence of single vs mixed type BCCs in other parts of the body. Histologically, mixed type BCCs exhibited an aggressive-growth pattern more frequently (64.6 % vs. 13.0 %, p < 0.0001). Positive surgical margins were significantly more common in mixed type BCC subgroup (17.8 % vs. 12.6 %, p = 0.02). Cutaneous BCCs with mixed histomorphology represented about one third of the cases. It is a common finding in routine pathological practice, probably suggestive of evolution and phenotypic transformation of the cancer. Since mixed type BCCs are frequently composed of aggressive histological subtypes, regardless the

    Basal cell carcinoma (BCC) with matrical differentiation is a fairly rare neoplasm, with about 30 cases documented mainly as isolated case reports. We studied a series of this neoplasm, including cases with an atypical matrical component, a hitherto unreported feature. Lesions coded as BCC with matrical differentiation were reviewed; 22 cases were included. Immunohistochemical studies were performed using antibodies against BerEp4, β-catenin, and epithelial membrane antigen (EMA). Molecular genetic studies using Ion AmpliSeq Cancer Hotspot Panel v2 by massively parallel sequencing on Ion Torrent PGM were performed in 2 cases with an atypical matrical component (1 was previously subjected to microdissection to sample the matrical and BCC areas separately). There were 13 male and 9 female patients, ranging in age from 41 to 89 years. Microscopically, all lesions manifested at least 2 components, a BCC area (follicular germinative differentiation) and areas with matrical differentiation. A BCC component dominated in 14 cases, whereas a matrical component dominated in 4 cases. Matrical differentiation was recognized as matrical/supramatrical cells (n=21), shadow cells (n=21), bright red trichohyaline granules (n=18), and blue-gray corneocytes (n=18). In 2 cases, matrical areas manifested cytologic atypia, and a third case exhibited an infiltrative growth pattern, with the tumor metastasizing to a lymph node. BerEP4 labeled the follicular germinative cells, whereas it was markedly reduced or negative in matrical areas. The reverse pattern was seen with β-catenin. EMA was negative in BCC areas but stained a proportion of matrical/supramatrical cells. Genetic studies revealed mutations of the following genes: CTNNB1, KIT, CDKN2A, TP53, SMAD4, ERBB4, and PTCH1, with some differences between the matrical and BCC components. It is concluded that matrical differentiation in BCC in most cases occurs as multiple foci. Rare neoplasms manifest atypia in the matrical areas

    Full Text Available Background: Photodynamic therapy is frequently applied for non-invasive destruction of basal cell carcinomas (BCC of the skin; though, there is lack of evidence for efficacy of the method. Aim: To assess objective response of BCCs to photodynamic therapy with intralesional administration of photosensitizer Radachlorin in patients with different clinical forms, stages, flow patterns and localization of BCC. Materials and methods: 45  stage I–II BCCs patients with primary and recurrent solitary (ulcerative, superficial, scleroderma-like and nodular forms and multiple lesions (predominantly Т₁– Т₂N₀M₀, with difficult to treat localization and high risk of recurrence were included during the period from March 2004 to March 2007. All patients received one cycle of photodynamic therapy with intralesional Radachlorin (0.5–1  ml/1  cm² tumor surface and irradiation dose 300  J/cm² (wavelength 662 nm. A primary outcome measure was grade of clinical and cytological lesion regression after three months. Secondary outcome measure was stable clinical and cytological reaction at the lesion site. In the long-term, lesion recurrence was assessed yearly during 5 years. Results: Complete regression of BCCs was found in 43  (95.5% patients and 47  (95.9% lesions. In 2 (4.5% patients with partial regression of 2 (4.1% lesions repeated cycles of photodynamic therapy resulted in complete response. In BCCs Т₁N₀M₀, early outcome was independent from the clinical form of the diseases; by contrast, in BCCs Т₂N₀M₀, treatment of scleroderma-like BCCs was non-significantly less effective (66.7% compared to nodular, surface (100% for both and ulcerative (92.8% forms. In the long-term, 1  tumor recurrence was observed after 29 months at the site of completely regressed ulcerative lesion. Conclusion: Photodynamic therapy with intralesional administration of photosensitizer Radachlorin is an effective treatment method for different

    The SafeTy Events in VIsmodEgib study (STEVIE, ClinicalTrials.gov, NCT01367665), assessed safety and efficacy of vismodegib-a first-in-class Hedgehog pathway inhibitor demonstrating clinical benefit in advanced basal cell carcinoma (BCC)-in a patient population representative of clinical practice. Primary analysis data are presented. Patients with locally advanced or metastatic BCC received oral vismodegib 150 mg/d until progressive disease, unacceptable toxicity, or withdrawal. Primary objective was safety. Efficacy variables were assessed as secondary end-points. Evaluable adult patients (N = 1215, 1119 locally advanced; 96 metastatic BCC) from 36 countries were treated; 147 patients (12%) remained on study at time of reporting. Median (range) treatment duration was 8.6 (0-44) months. Most patients (98%) had ≥1 treatment-emergent adverse event (TEAE). The incidence of the most common TEAEs was consistent with reports in previous analyses. No association between creatine phosphokinase (CPK) abnormalities and muscle spasm was observed. Serious TEAEs occurred in 289 patients (23.8%). Exposure ≥12 months did not lead to increased incidence or severity of new TEAEs. The majority of the most common TEAEs ongoing at time of treatment discontinuation resolved by 12 months afterwards, regardless of Gorlin syndrome status. Response rates (investigator-assessed) in patients with histologically confirmed measurable baseline disease were 68.5% (95% confidence interval (CI) 65.7-71.3) in patients with locally advanced BCC and 36.9% (95% CI 26.6-48.1) in patients with metastatic BCC. The primary analysis of STEVIE demonstrates that vismodegib is tolerable in typical patients in clinical practice; safety profile is consistent with that in previous reports. Long-term exposure was not associated with worsening severity/frequency of TEAEs. Investigator-assessed response rates showed high rate of tumour control. CLINICALTRIALS.GOV: NCT01367665.

    Epidemiologic studies consistently find enhanced risk of basal cell carcinoma of the skin among individuals exposed to ionizing radiation, but it is unclear whether the radiation effect occurs for squamous cell carcinoma. It is also not known whether subgroups of individuals are at greater risk, eg, those with radiation sensitivity or high ultraviolet radiation exposure. We analyzed data from a case-control study of keratinocyte cancers in New Hampshire. Incident cases diagnosed in 1993-1995 and 1997-2000 were identified through a state-wide skin cancer surveillance system, and controls were identified through the Department of Transportation and Center for Medicare and Medicaid Service Files (n = 1121 basal cell carcinoma cases, 854 squamous cell carcinoma cases, and 1049 controls). We found an association between history of radiation treatment and basal cell carcinoma. The association was especially strong for basal cell carcinomas arising within the radiation treatment field (odds ratio = 2.6; 95% confidence interval = 1.5-4.3), and among those treated with radiation therapy before age 20 (3.4; 1.8-6.4), those whose basal cell carcinomas occurred 40 or more years after radiation treatment (3.2; 1.8-5.8), and those treated with radiation for acne (11; 2.7-49). Similar age and time patterns of risk were observed for squamous cell carcinoma, although generally with smaller odds ratios. For basal cell carcinoma, early exposure to radiation treatment was a risk factor largely among those without a history of severe sunburns, whereas for squamous cell carcinoma, radiation treatment was a risk factor primarily among those with a sun-sensitive skin type (ie, a tendency to sunburn). Radiation treatment, particularly if experienced before age 20, seems to increase the long-term risk of both basal and squamous cell carcinomas of the skin. These risks may differ by sun exposure or host response to sunlight exposure.

    We present a combined reflectance confocal microscopy (RCM) and optical coherence tomography (OCT) approach, integrated within a single optical layout, for diagnosis of basal cell carcinomas (BCCs) and delineation of margins. While RCM imaging detects BCC presence (diagnoses) and its lateral spreading (margins) with measured resolution of ˜1 μm, OCT imaging delineates BCC depth spreading (margins) with resolution of ˜7 μm. When delineating margins in 20 specimens of superficial and nodular BCCs, depth could be reliably determined down to ˜600 μm, and agreement with histology was within about ±50 μm.

    The authors evoke some characteristics of the basal cell carcinoma (slow evolution, local morbidity) and report and discuss the case of a giant basal cell trunk carcinoma, associated with several symptoms (pain, bleeding, anaemia), already metastatic at the moment of diagnosis, and locally treated by irradiation. Due to its size and expansion, this carcinoma was considered as inoperable. An external radiotherapy has been performed and resulted in a significant clinical tumour reduction. But the metastatic risk is high in such cases. Radiotherapy is then a therapeutic option for a local treatment with a durable efficiency. Short communication

    Lectins bind tightly to carbohydrate moieties on cell surfaces. Alterations in lectin binding have been reported to accompany epidermal cell differentiation, marking alterations in membrane sugars during this process. The presence of UEA I (Ulex europaeus agglutinin I) L-fucose-specific lectin-binding sites has been used as a marker for terminally differentiated (committed) keratinocytes. In this article, we report the presence of UEA-I-binding sites on squamous keratinocytes of well-differentiated squamous cell carcinomas, with patchy loss of UEA I positivity on poorly differentiated cells of squamous cell carcinomas, suggesting a possible use for this technique in the rapid assessment of less differentiated areas within the squamous cell tumor. The absence of UEA-I-binding sites on basal cell carcinomas may be related to an inability of cells comprising this tumor to convert the L-D-pyranosyl moiety on basal cells to the L-fucose moiety, resulting in an inability of basal cell carcinoma cell to undergo terminal differentiation into a committed keratinocyte.

    Yes-associated protein (YAP) is a transcriptional co-activator of hippo signaling pathway, which plays an important role in organ size control and tumorigenesis. Here we report that YAP and its downstream transcriptional targets CCN1 and CCN2 are markedly elevated in keratinocytes in human skin basal cell carcinoma tumor islands. In human keratinocytes, knockdown of YAP significantly reduced expression of CCN1 and CCN2, and repressed proliferation and survival. This inhibition of proliferation and survival was rescued by restoration of CCN1 expression, but not by CCN2 expression. In basal cell carcinoma stroma, CCN2-regulated genes type I collagen, fibronectin, and α-smooth muscle actin were highly expressed. Furthermore, atomic force microscopy revealed increased tissue stiffness in basal cell carcinoma stroma compared to normal dermis. These data provide evidence that up-regulation of YAP in basal cell carcinoma impacts both aberrant keratinocyte proliferation, via CCN1, and tumor stroma cell activation and stroma remodeling, via CCN2. Targeting YAP and/or CCN1 and CCN2 may provide clinical benefit in basal cell carcinoma. Copyright © 2014 American Society for Investigative Pathology. Published by Elsevier Inc.

    The Hedgehog pathway inhibitor vismodegib has shown clinical benefit in patients with advanced basal cell carcinoma and is approved for treatment of patients with advanced basal cell carcinoma for whom surgery is inappropriate. STEVIE was designed to assess the safety of vismodegib in a situation similar to routine practice, with a long follow-up. In this multicentre, open-label trial, adult patients with histologically confirmed locally advanced basal cell carcinoma or metastatic basal cell carcinoma were recruited from regional referral centres or specialist clinics. Eligible patients were aged 18 years or older with an Eastern Cooperative Oncology Group (ECOG) performance status of 0-2, and adequate organ function. Patients with locally advanced basal cell carcinoma had to have been deemed ineligible for surgery. All patients received 150 mg oral vismodegib capsules once a day on a continuous basis in 28-day cycles. The primary objective was safety (incidence of adverse events until disease progression or unacceptable toxic effects), with assessments on day 1 of each treatment cycle (28 days) by principal investigator and coinvestigators at the site. Efficacy variables were assessed as secondary endpoints. The safety evaluable population included all patients who received at least one dose of study drug. Patients with histologically confirmed basal cell carcinoma who received at least one dose of study drug were included in the efficacy analysis. An interim analysis was pre-planned after 500 patients achieved 1 year of follow-up. This trial is registered with ClinicalTrials.gov, number NCT01367665. The study is still ongoing. Between June 30, 2011, and Nov 6, 2014, we enrolled 1227 patients. At clinical cutoff (Nov 6, 2013), 499 patients (468 with locally advanced basal cell carcinoma and 31 with metastatic basal cell carcinoma) had received study drug and had the potential to be followed up for 12 months or longer. Treatment was discontinued in 400 (80

    Full Text Available Backgound/aim: Basal cell carcinoma (BCC is the most frequent form of carcinomas in the whites. Among the environmental factors, the most important risk factor for its occurrence is the exposure to sun radiation. The aim of this study was to assess the role of the sun radiation in the development of basal cell carcinoma BCC in the Montenegrian population. Methods. A case-control study was conducted in a period from 2002-2003. The study group included 100 histopatologically confirmed cases with BCC, while the control group included 100 patients from the same population, who did not present skin cancer and who were individually matched with the cases from the study group by sex and age (± 5 years. All the participants were interviewed using an epidemiological questionnaire. For statistical analysis, the χ2 test and univariate logistic regression analysis were used. Results. The risk for development of BCC was increased in the persons: that always had burns with no tan during the exposure to sunlight (OR = 1.75; 95% CI = 1.20-2.55; p = 0.003; that developed sunburns after two hours of the exposure to sunlight (OR = 3.72; 95% CI = 2.39-5.79; p < 0.001 that kept light tan or remained without changes in childhood and adolescence after the repeated exposures to sunlight (OR = 2.92; 95% CI = 1.89-4.52; p < 0.001 that often had severe and painful sunburns (OR = 4.48; 95% CI = 2.74-7.33; p < 0.001. Conclusion. Our study confirmed the significance of sunlight exposure for the development of BCC.

    The surface-enhanced Raman signals of 4-aminothiophenol (4-ATP) attached to the surface of colloidal gold nanoparticles with size distribution of 2 to 5 nm were used as a labeling agent to detect basal cell carcinoma (BCC) of the skin. The enhanced Raman band at 1075 cm-1 corresponding to the C-S stretching vibration in 4-ATP was observed during attachment to the surface of the gold nanoparticles. The frequency and intensity of this band did not change when the colloids were conjugated with BerEP4 antibody, which specifically binds to BCC. We show the feasibility of imaging BCC by surface-enhanced Raman spectroscopy, scanning the 1075 cm-1 band to detect the distribution of 4-ATP-coated gold nanoparticles attached to skin tissue ex vivo.

    The incidence of skin cancer is still increasing mostly in in industrialized countries with light- skinned people. Late tumour detection is the main reason of the high mortality associated with skin cancer. The accessibility of early diagnostics of skin cancer in Latvia is limited by several factors, such as high cost of dermatology services, long queues on state funded oncologist examinations, as well as inaccessibility of oncologists in the countryside regions - this is an actual clinical problem. The new strategies and guidelines for skin cancer early detection and post-surgical follow-up intend to realize the full body examination (FBE) by primary care physicians (general practitioners, interns) in combination with classical dermoscopy. To implement this approach, a semi- automated method was established. Developed software analyses the combination of 3 optical density images at 540 nm, 650 nm, and 950 nm from pigmented skin malformations and classifies them into three groups- nevi, pigmented basal cell carcinoma or melanoma.

    This work demonstrated the discrimination among basal cell carcinoma (BCC) and normal human skin in vivo using near-infrared Raman spectroscopy. Spectra were obtained in the suspected lesion prior resectional surgery. After tissue withdrawn, biopsy fragments were submitted to histopathology. Spectra were also obtained in the adjacent, clinically normal skin. Raman spectra were measured using a Raman spectrometer (830 nm) with a fiber Raman probe. By comparing the mean spectra of BCC with the normal skin, it has been found important differences in the 800-1000 cm-1 and 1250-1350 cm-1 (vibrations of C-C and amide III, respectively, from lipids and proteins). A discrimination algorithm based on Principal Components Analysis and Mahalanobis distance (PCA/MD) could discriminate the spectra of both tissues with high sensitivity and specificity.

    Purpose: To treat squamous cell and basal cell carcinoma of the skin with the Freiburg flap applicator using a high dose rate modality of an Elekta Flexitron or MicroSelectron for radiation delivery by compensating the dose deviation resulting from the incomplete scatter environment. Methods: Patients were selected to have lesions greater than or equal to 2cm. A mask might be needed depending on special locations. The lesions on the eyelid and face presented in this research were, however, treated without a mask. Cutting the flap into a shape conformal to the target and attaching it to the mask were used in order to make the treatment reproducible. Patients were scanned with a Philips Big Bore Brilliant CT. A 1cm margin was added to the lesion. An Elekta Oncentra Brachy treatment planning system ver. 4.3 was used for treatment planning. 40 Gy in 10 or 8 fractions was prescribed to the 1cm depth. The Freiburg flap was aligned and verified by CT scanning prior to treatment. Results: Three patients with squamous cell and basal cell carcinoma of the skin were treated with the Freiburg flap applicator. Lesion sizes ranged from 2cm to 6 cm in a maximum dimension. With treatment planning, we made a dose correction for compensating the dose deviation resulting from the incomplete scatter environment of the flap applicators exposed to air. The flap was also covered by a 4cm bolus in order to obtain more back scattered radiation during treatment. Six month follow up showed a very good cosmetic result. Conclusion: The Freiburg flap brachytherapy offers a non-invasive skin cancer treatment with a high skin dose delivered to the tumor while a low dose sparing the surrounding health tissue. It is a promising alternative to skin cancer surgery or external beam radiation therapy.

    BACKGROUND Basal cell carcinoma (BCC) greater than 5 cm in diameter is called giant basal cell carcinoma (GBCC), or super giant basal cell carcinoma if it has a diameter larger than 20 cm. Giant BCC only accounts for 0.5% of BCCs and super giant BCC is exceedingly rare. On account of their rarity, there are no established guidelines for GBCC treatment. CASE REPORT We describe a peculiar case of an 82-year-old woman with a GBCC carcinoma of the lower abdominal wall. The tumor was surgically removed with ipsilateral inguinal lymph nodes and the abdominal wall was reconstructed immediately with a pedicled deep inferior epigastric artery perforator (DIEP) flap. CONCLUSIONS Treatment of giant basal cell carcinoma is often difficult, especially in elderly patients with poor general health and multiple pathologies. The pedicled DIEP flap is rotated to cover the loss of substance without tension, and it is easy to harvest and transfer. This flap allowed a good result without local or systemic complication. We present this report as a reminder of the occasional occurrence of extremely aggressive BCCs. We believe that, especially for rare tumors like these, it is very useful for the entire scientific community to publish these cases and the therapeutic strategies used to treat them.

  11. Supraestructure maxillectomy and orbital exenteration for treatment of basal cell carcinoma of inferior eyelid: Case report and review

    2006-01-01

    Full Text Available Basal cell carcinoma (BCC is the most frequent type of skin cancer in humans, with cumulative exposure to ultraviolet radiation as an important risk factor for development of illness such as severe solar burns during childhood or adolescence. BCC is mainly located on sun-exposed sites, head and neck being the areas of more incidences; although nose, eyelids and periorbitary tissue are unfavorable due to cosmetic results that BCC involves. Tumors can be classified as nodular, superficial, micronodular, morphea variety, infiltrating, pigmented, metatypic and fibroepithelioma of Pinkus. Several treatment options such as surgical and nonsurgical are available. The goal of treatment is complete excision of the tumor with preservation of surrounding structures in a way aesthetically acceptable. Mohs′ micrographic surgery is the standard treatment for all nonmelanoma skin cancers. Orbital exenteration is also used for treatment of malignancies of ocular tissues, mainly squamous cell carcinoma, sebaceous cell carcinoma and BCC. The tissue beneath the surgical site can be left for second-intention granulation or covered with a cutaneous implant of partial thickness. The case of a 77-year-old patient is presented with BCC of inferior eyelid of 14 years′ duration, formerly managed with radiotherapy; however, due to recurrent illness and invasion to the maxillary antrum, he needed supraestructure maxillectomy with left orbital exenteration.

    Full Text Available OBJECTIVE: Mohs micrographic surgery is a specialized surgical procedure used to treat skin cancer. The purpose of this study was to better understand the profile of the patients who underwent the procedure and to determine how histology might be related to complications and the number of stages required for complete removal. METHODS: The records of patients who underwent Mohs micrographic surgery from October 2008 to November 2013 at the Dermatology Division of the Hospital of the Campinas University were assessed. The variables included were gender, age, anatomical location, histology, number of stages required and complications. RESULTS: Contingency tables were used to compare the number of stages with the histological diagnosis. The analysis showed that patients with superficial basal cell carcinoma were 9.03 times more likely to require more than one stage. A comparison between complications and histological diagnosis showed that patients with superficial basal cell carcinoma were 6.5 times more likely to experience complications. CONCLUSION: Although superficial basal cell carcinoma is typically thought to represent a less-aggressive variant of these tumors, its propensity for demonstrating “skip areas” and clinically indistinct borders make it a challenge to treat. Its particular nature may result in the higher number of surgery stages required, which may, as a consequence, result in more complications, including recurrence. Recurrence likely occurs due to the inadequate excision of the tumors despite their clear margins. Further research on this subtype of basal cell carcinoma is needed to optimize treatments and decrease morbidity.

    Skin cancer is the most common human malignancy and basal cell carcinoma (BCC) represents approximately 80% of the non-melanoma cases. Current methods of treatment require histopathological evaluation of the tissues by qualified personnel. However, this method is subjective and in some cases BCC can be confused with other structures in healthy skin, including hair follicles. In this preliminary study, we investigated the potential of Raman micro-spectroscopy (RMS) to discriminate between hair follicles and BCC in skin tissue sections excised during Mohs micrographic surgery (MMS). Imaging and diagnosis of skin sections was automatically generated using ' a priori'-built spectral model based on LDA. This model had 90 ± 9% sensitivity and 85 ± 9% specificity for discrimination of BCC from dermis and epidermis. The model used selected Raman bands corresponding to the largest spectral differences between the Raman spectra of BCC and the normal skin regions, associated mainly with nucleic acids and collagen type I. Raman spectra corresponding to the epidermis regions of the hair follicles were found to be closer to those of healthy epidermis rather than BCC. Comparison between Raman spectral images and the gold standard haematoxylin and eosin (H&E) histopathology diagnosis showed good agreement. Some hair follicle regions were misclassified as BCC; regions corresponded mainly to the outermost layer of hair follicle (basal cells) which are expected to have higher nucleic acid concentration. This preliminary study shows the ability of RMS to distinguish between BCC and other tissue structures associated to healthy skin which can be confused with BCC due to their similar morphology.

    Basal Cell Carcinoma (BCC) is one of the most diagnosed cancers worldwide. It develops due to an unrestrained Sonic Hedgehog (SHH) signaling activity in basal cells of the skin. Certain subtypes of BCC are more aggressive than others, although the molecular basis of this phenomenon remains unknown. We have previously reported that Neogenin-1 (NEO1) is a downstream target gene of the SHH/GLI pathway in neural tissue. Given that SHH participates in epidermal homeostasis, here we analyzed the epidermal expression of NEO1 in order to identify whether it plays a role in adult epidermis or BCC. We describe the mRNA and protein expression profile of NEO1 and its ligands (Netrin-1 and RGMA) in human and mouse control epidermis and in a broad range of human BCCs. We identify in human BCC a significant positive correlation in the levels of NEO1 receptor, NTN-1 and RGMA ligands with respect to GLI1 , the main target gene of the canonical SHH pathway. Moreover, we show via cyclopamine inhibition of the SHH/GLI pathway of ex vivo cultures that NEO1 likely functions as a downstream target of SHH/GLI signaling in the skin. We also show how Neo1 expression decreases throughout BCC progression in the K14-Cre:Ptch1 lox/lox mouse model and that aggressive subtypes of human BCC exhibit lower levels of NEO1 than non-aggressive BCC samples. Taken together, these data suggest that NEO1 is a SHH/GLI target in epidermis. We propose that NEO1 may be important in tumor onset and is then down-regulated in advanced BCC or aggressive subtypes.

  2. The SINS trial: A randomised controlled trial of excisional surgery versus imiquimod 5% cream for nodular and superficial basal cell carcinoma

    2010-04-01

    Full Text Available Abstract Background Basal cell carcinoma is the commonest human cancer. Despite increasing incidence it remains poorly researched. While not life threatening it can cause significant cosmetic disfigurement. Imiquimod, a cream which enhances the body's immune response, may help deal with the number of cases that occur in low-risk sites, especially when good cosmetic results and home use without surgery are needed. This study aims 1. To compare excisional surgery with imiquimod cream for nodular or superficial basal cell carcinoma in low risk sites, with respect to 3 year clinical clearance, cost-effectiveness and cosmetic results. 2. To ascertain if certain phenotypic features and gene polymorphisms predict tumour responsiveness to treatment. Methods/Design Five hundred participants with low risk nodular or superficial basal cell carcinoma will be recruited from hospitals to this multi-centre, randomised, parallel group, controlled phase III trial. Treatment in the imiquimod group is for 6 weeks for superficial basal cell carcinoma and 12 weeks for nodular basal cell carcinoma. Both treatment groups are followed up in clinic for 3 years. Primary outcome variable: the proportion of participants with clinical evidence of success (no recurrence at 3 years. The primary outcome will be compared between the two treatment groups. Secondary outcomes include: i clinical success at 1, 2 and 5 years, ii time to first recurrence, iii cosmetic appearance of lesion site after treatment, iv level of pain, and v cost-effectiveness. Safety and tolerability data will also be reported. Discussion This study protocol describes a pragmatic randomised controlled trial which it is hoped will address the above uncertainties. Three-year results will be available towards the end of 2010. Trial registration Meta-register: NCT00066872, Eudract No. 2004-004506-24, ISRCTN48755084.

    Full Text Available Context (Background: Imiquimod (IMQ 5% cream is an immunomodulatory and antitumorigenic agent, which was used as a topical treatment regimen, who had periocular basal cell carcinoma (BCC. Aim: This study aims to present three cases with large BCC at the medial canthal area treated with IMQ 5% cream. Materials and Methods: IMQ 5% cream was used in three patients with ages 45, 49, and 73 who preferred medical treatment over surgery. Following incisional biopsy IMQ cream was used once a day, 5 times a week and the patients were followed up weekly during 12 week treatment period and monthly after the clearance of the lesion. Results: Erythema and erosion on the surface of the lesion, injection of conjunctiva, burning and itching sensation, epiphora and punctate keratitis were seen in all patients during the treatment period. The ophthalmic side effects could be managed by topical lubricating eye drops and the inflammatory reactions resolved within 1 month after cessation of therapy. The patients were followed up for at least 3 years without tumor recurrence and the biopsies taken from the suspected area were found to be tumor free. Conclusion: Surgical excision of carcinoma of the eyelid at medial canthal area can be difficult without causing damage to the lacrimal system and reconstruction of the defect may need grafts or flaps. IMQ may provide an alternative therapy to surgery in certain cases.

    Arecoline, the most abundant areca alkaloid, has been reported to decrease interleukin-6 (IL-6) levels in epithelial cancer cells. Since IL-6 overexpression contributes to the tumorigenic potency of basal cell carcinoma (BCC), this study was designed to investigate whether arecoline altered IL-6 expression and its downstream regulation of apoptosis and the cell cycle in cultured BCC-1/KMC cells. BCC-1/KMC cells and a human keratinocyte cell line, HaCaT, were treated with arecoline at concentrations ranging from 10 to 100 μg/ml, then IL-6 production and expression of apoptosis- and cell cycle progress-related factors were examined. After 24 h exposure, arecoline inhibited BCC-1/KMC cell growth and decreased IL-6 production in terms of mRNA expression and protein secretion, but had no effect on HaCaT cells. Analysis of DNA fragmentation and chromatin condensation showed that arecoline induced apoptosis of BCC-1/KMC cells in a dose-dependent manner, activated caspase-3, and decreased expression of the anti-apoptotic protein Bcl-2. In addition, arecoline induced progressive and sustained accumulation of BCC-1/KMC cells in G2/M phase as a result of reducing checkpoint Cdc2 activity by decreasing Cdc25C phosphatase levels and increasing p53 levels. Furthermore, subcutaneous injection of arecoline led to decreased BCC-1/KMC tumor growth in BALB/c mice by inducing apoptosis. This study demonstrates that arecoline has potential for preventing BCC tumorigenesis by reducing levels of the tumor cell survival factor IL-6, increasing levels of the tumor suppressor factor p53, and eliciting cell cycle arrest, followed by apoptosis. Highlights: ► Arecoline has potential to prevent against basal cell carcinoma tumorigenesis. ► It has more effectiveness on BCC as compared with a human keratinocyte cell line. ► Mechanisms involved including reducing tumor cells’ survival factor IL-6, ► Decreasing Cdc25C phosphatase, enhancing tumor suppressor factor p53, ► Eliciting G2/M

    We report a case of a 66-year-old man with locally advanced and metastatic basal cell carcinoma (BCC) causing spinal cord compression, which was treated with spinal surgery and subsequent vismodegib. The patient presented with a large fungating chest wall lesion and a metastasis in T8 that was causing cord compression. He had neurosurgical decompression of the T8 lesion and fixation of the spine. Punch biopsy from the fungating chest wall lesion showed a BCC with some malignant squamous differentiation (basosquamous). Histopathological examination of the metastatic lesion in T8 at the time of surgical decompression identified features identical to the punch biopsy. The patient was referred to the oncology clinic for adjuvant treatment. In light of his metastatic disease and the large area over his chest wall that could not fully be covered by radiotherapy, he was treated with the novel oral Hedgehog signalling pathway (HHSP) inhibitor vismodegib, which led to marked improvement. © 2016 British Association of Dermatologists.

    Skin carcinoma, particularly basal cell carcinoma, and its treatment can result in large defects of the hairy skull. A 53-year-old man is described who was surgically treated for a large basal cell carcinoma invading the skin and underlying tissue at the top of the hairy skull. Treatment consisted of resecting the tumor and external part of the skull bone. To protect the brain and to cover the defect of the hairy skull, an acrylic resin skull prosthesis with hair was designed to mask the defect. The skull prosthesis was retained on 8 extraoral implants placed at the margins of the defect in the skull bone. The patient was satisfied with the treatment outcome.

    The standard diagnostic procedure for basal cell carcinoma (BCC) is invasive tissue biopsy with time-consuming histological examination. To reduce the number of biopsies, noninvasive optical methods have been developed providing high-resolution skin examination. We present direct comparison of a reflectance confocal microscope (RLSM) and a multiphoton tomograph (MPT) for BCC diagnosis. Both systems are applied to nine patients prior to surgery, and the results are analyzed, including histological results. Both systems prove suitable for detecting typical characteristics of BCC in various stages. The RLSM allows large horizontal overview images to be obtained, enabling the investigator to find the regions of interest quickly, e.g., BCC nests. Elongated cells and palisading structures are easily recognized using both methods. Due to the higher resolution, changes in nucleus diameter or cytoplasm could be visualized with the MPT. Therefore, the nucleus diameter, nucleus/cytoplasm ratio, and cell density are estimated for normal and BCC cells using the MPT. The nucleus of elongated BCC cells is significantly longer than other measured normal skin cells, whereas the cell density and nucleus/cytoplasm ratio of BCC cannot be significantly distinguished from granular cells.

    We present a hand-held implementation and preliminary evaluation of a combined optical coherence tomography (OCT) and reflectance confocal microscopy (RCM) probe for detecting and delineating the margins of basal cell carcinomas (BCCs) in human skin in vivo. A standard OCT approach (spectrometer-based) with a central wavelength of 1310 nm and 0.11 numerical aperture (NA) was combined with a standard RCM approach (830-nm wavelength and 0.9 NA) into a common path hand-held probe. Cross-sectional OCT images and enface RCM images are simultaneously displayed, allowing for three-dimensional microscopic assessment of tumor morphology in real time. Depending on the subtype and depth of the BCC tumor and surrounding skin conditions, OCT and RCM imaging are able to complement each other, the strengths of each helping overcome the limitations of the other. Four representative cases are summarized, out of the 15 investigated in a preliminary pilot study, demonstrating how OCT and RCM imaging may be synergistically combined to more accurately detect BCCs and more completely delineate margins. Our preliminary results highlight the potential benefits of combining the two technologies within a single probe to potentially guide diagnosis as well as treatment of BCCs.

    Raman spectroscopy has been employed to identify differences in the biochemical constitution of malignant [basal cell carcinoma (BCC) and melanoma (MEL)] cells compared to normal skin tissues, with the goal of skin cancer diagnosis. We collected Raman spectra from compounds such as proteins, lipids, and nucleic acids, which are expected to be represented in human skin spectra, and developed a linear least-squares fitting model to estimate the contributions of these compounds to the tissue spectra. We used a set of 145 spectra from biopsy fragments of normal (30 spectra), BCC (96 spectra), and MEL (19 spectra) skin tissues, collected using a near-infrared Raman spectrometer (830 nm, 50 to 200 mW, and 20 s exposure time) coupled to a Raman probe. We applied the best-fitting model to the spectra of biochemicals and tissues, hypothesizing that the relative spectral contribution of each compound to the tissue Raman spectrum changes according to the disease. We verified that actin, collagen, elastin, and triolein were the most important biochemicals representing the spectral features of skin tissues. A classification model applied to the relative contribution of collagen III, elastin, and melanin using Euclidean distance as a discriminator could differentiate normal from BCC and MEL.

    Primary analysis from the pivotal ERIVANCE BCC study resulted in approval of vismodegib, a Hedgehog pathway inhibitor indicated for treatment of adults with metastatic or locally advanced basal cell carcinoma (BCC) that has recurred after surgery or for patients who are not candidates for surgery or radiation. An efficacy and safety analysis was conducted 12 months after primary analysis. This was a multinational, multicenter, nonrandomized, 2-cohort study in patients with measurable and histologically confirmed locally advanced or metastatic BCC taking oral vismodegib (150 mg/d). Primary outcome measure was objective response rate (complete and partial responses) assessed by independent review facility. After 12 months of additional follow-up, median duration of exposure to vismodegib was 12.9 months. Objective response rate increased from 30.3% to 33.3% in patients with metastatic disease, and from 42.9% to 47.6% in patients with the locally advanced form. Median duration of response in patients with locally advanced BCC increased from 7.6 to 9.5 months. No new safety signals emerged with extended treatment duration. Limitations include low prevalence of advanced BCC and challenges of designing a study with heterogenous manifestations. The 12-month update of the study confirms the efficacy and safety of vismodegib in management of advanced BCC. Copyright © 2015 American Academy of Dermatology, Inc. Published by Elsevier Inc.

    In an in vitro study, the effect of light polarization on the efficiency of 5-aminolaevulinic acid (ALA) photodynamic therapy (PDT) of basal cell carcinoma (BCC) was investigated. Three states of light polarization (non-polarized, linearly polarized, and circularly polarized) were considered. Cells were exposed to green (532 pm 20 nm) irradiation from light emitting diodes. Cell survival was measured by the colorimetric assay (WST-1) and Trypan blue staining. The colorimetric assay showed a pronounced decrease in the cell viability (up to 30%) using polarized light compared to the non-polarized one in the wavelength region used. Similar results were obtained by the cell counting method (20-30% increase in cell death). The observed effect was dependent on the concentration of photosensitizer. The effect is more expressed in the case of linearly polarized light compared to the circularly polarized one. Results show that the use of polarized light increases the efficiency of in vitro ALA-PDT of BCC. Utilizing polarized light, it is possible to obtain the same effect from PDT by lower concentrations of photosensitizer. Additionally, the concentration dependency of PDT response and photo-bleaching is also reduced.

    Full Text Available Although malignant melanoma (MM and both basal cell carcinoma (BCC and actinic keratosis (AK are sun-induced lesions, the coexistence of these entities at the same anatomical site (collision tumour is exceedingly rare. We report the case of a 54-year-old woman with a known history of xeroderma pigmentosum variant (XPV who presented with 2 separate skin lesions over the middle and upper right forearm, respectively. The clinical impression was that of BCCs or squamous cell lesions. On histological examination, both specimens showed features of melanoma in situ (MIS. In the first lesion, MIS merged with and colonised a superficial and focally invasive BCC. In the second lesion, MIS merged with an AK. No separate invasive nests of malignant melanoma were seen in either specimen. The atypical melanocytes were highlighted by Melan-A and HMB-45 immunostaining, whereas the epithelial cells in both the BCC and AK stained with the pancytokeratin MNF-116. The patient had a previous history of multiple MMs and non-melanomatous skin cancers and finally developed widespread metastatic malignant melanoma, which proved fatal. The rare and interesting phenomenon of collision tumours may pose diagnostic difficulties. To our knowledge, this is the first reported simultaneous presentation of cytologically malignant collision tumours in a patient with XPV.

    Human papillomaviruses (HPVs) are a large and ubiquitous group of viruses that some of them have been suggested as a co-factor in the development of non-melanoma skin cancers. The aim of this meta-analysis study was to evaluate HPVs' prevalence in basal cell carcinoma (BCC) of the skin and the risk of them in the BCC patients compared with the healthy controls. Five databases were searched from January 1980 to February 2017. A random-effects meta-analysis was done with the event rate (ER) for the prevalence of HPVs and odds ratio (OR) for estimation of the incidence of HPVs. Out of 1087 studies, 45 studies were included in the review. The pooled analysis demonstrated that the incidence of γ-HPV was effective in the BCC patients compared with the healthy controls [OR = 1.97; 95% CI: 1.52-2.55; p 0.05). The pooled ER of incidence of β1-HPV in the BCC patients was z3.3% and for β2-HPV in BCC patients was 44.2%. In conclusion, this meta-analysis showed that probably the risk of γ-HPV was more on BCC patients and also the rate of γ-HPV was higher than α-, β- and EV-HPVs in the BCC patients.

    Vismodegib is an oral inhibitor of the Hedgehog signaling pathway and has been used to treat basal cell carcinoma (BCC) in adults. This article reports clearance of a nodular BCC of the nasal tip in an 8-year-old boy with xeroderma pigmentosum (XP). BCC can pose therapeutic challenges when located in areas that are not amenable to traditional therapies such as Mohs micrographic surgery or topical agents. Vismodegib was used at a dose of 150 mg/day to treat the boy's BCC. After 4 months of therapy, we achieved complete clinical clearance. During 21 months of follow-up, the patient's nose remained clinically clear of tumor. Vismodegib was successfully used to treat a child with XP and nodular BCC. Our goal in using vismodegib was tumor regression while avoiding cosmetic and functional disfigurement. Vismodegib was effective in clinically clearing the tumor, and the patient has shown no signs of recurrence. Further studies are warranted. © 2017 Wiley Periodicals, Inc.

    Fluorescence confocal microscopy (FCM) represents a first step toward a rapid "bedside pathology" in the Mohs surgery setting and in other fields of general pathology. To describe and validate FCM criteria for the main basal cell carcinoma (BCC) subtypes and to demonstrate the overall agreement with classic pathologic analysis of hematoxylin-eosin-stained samples. DESIGN A total of 69 BCCs from 66 patients were prospectively imaged using ex vivo FCM. Confocal mosaics were evaluated in real time and compared with classic pathologic analysis. Department of Dermatology, Hospital Clínic of Barcelona, Barcelona, Spain, between November 2010 and July 2011. Patients with BCC attending the Mohs Surgery Unit. Presence or absence of BCC and histological subtype (superficial, nodular, and infiltrating) in the confocal mosaics. Eight criteria for BCC were described, evaluated, and validated. Although there were minor differences among BCC subtypes, the most BCC-defining criteria were peripheral palisading, clefting, nuclear pleomorphism, and presence of stroma. These criteria were validated with independent observers (κ values >0.7 [corrected] for most criteria). We herein propose, describe, and validate FCM criteria for BCC diagnosis. Fluorescence confocal microscopy is an attractive alternative to histopathologic analysis of frozen sections during Mohs surgery because large areas of freshly excised tissue can be assessed in real time without the need for tissue processing while minimizing labor and costs.

    In this work, we use nonlinear spectral imaging based on two-photon excited fluorescence (TPEF) and second harmonic generation (SHG) for analyzing the morphology of collagen and elastin and their biochemical variations in basal cell carcinoma (BCC), squamous cell carcinoma (SCC) and normal skin tissue. It was found in this work that there existed apparent differences among BCC, SCC and normal skin in terms of their thickness of the keratin and epithelial layers, their size of elastic fibers, as well as their distribution and spectral characteristics of collagen. These differences can potentially be used to distinguish BCC and SCC from normal skin, and to discriminate between BCC and SCC, as well as to evaluate treatment responses.

    Ultraviolet radiation plays an important role in the pathogenesis of non-melanoma skin cancer. Outdoor workers, including farmers, experience higher exposure levels compared to the general population. Available literature data suggest that occupational ultraviolet exposure represents an independent risk factor for squamous cell carcinoma; whereas for basal cell carcinoma (BCC) this association still remains unclarified. To analyse the epidemiological, clinical and histological data of patients diagnosed with BCC, and correlate them with outdoor occupation in farmers. Individuals with histologically diagnosed BCCs, between September 2013 and September 2015, were included in the study. Their medical data, including epidemiological, clinical and histological characteristics, were recorded and analysed in conjunction with the occupation. Farmers were identified based on their specific public health insurance. Three hundred and forty patients, with 542 BCCs were included in the study. One hundred and twenty (35.3%) were farmers. Mean age of farmers was lower than non-farmers (66.0 ± 9.1 years vs. 75 ± 6.6 years, Mann-Whitney U-test, P Farmers had a sixfold higher probability for exhibiting photodamaged skin (OR = 6.02, 95% CI: 3.66-9.90, P Farmer workers were more likely to exhibit infiltrative or morpheaform BCC, but less likely to develop superficial BCC. Our results indicate a higher risk of earlier development of more aggressive histological subtypes of BCCs in farmers. Photodamage was also more common in this group.

    Matrix metalloproteinases (MMPs) mediate the degradation of all types of collagens and other extracellular matrix components (elastin, proteoglycans, and laminin), their synthesis and accumulation play a key role in the hydrolysis of basement membrane. MMPs are involved in a wide range of proteolytic processes in the presence of different physiological and pathological changes, including inflammation, wound healing, angiogenesis, and carcinogenesis. to study the specific features of MMP-1 and MMP-9 expression in different stages of skin photoaging, in the foci of actinic keratosis and basal cell carcinoma by immunohistochemical examination. 12 samples of the healthy skin (6 samples of the eyelid skin with Glogau grade II photoaging; 6 ones of eyelid skin with Glogau grades III-IV photoaging) and biopsies from 8 foci of actinic keratosis and from 8 ones of basal cell carcinoma were examined. A positive reaction to MMPs was shown as different brown staining intensity in the cytoplasm of keratinocytes/tumor cells. MMP-1 and MMP-9 expression was recorded in 67% of the histological specimens of the Glogau grade III photoaged skin and in 100% of those of Glogau grade IV. In the foci of actinic keratosis, the expression of MMP-1 was observed in 62.5% of cases and that of MMP-9 was seen in 87.5%. In basal cell carcinoma, the expression of MMP-1 and MMP-9 was detected in all investigated samples. The immunomorphological findings are indicative of the important role of the level of MMP-1 and MMP-9 expression that is associated with the degree of progression of skin photoaging processes. Minimal MMP-1 and MMP-9 expression was recorded even in grades III-IV photoaging and in the foci of actinic keratosis. Intense MMP-1 and MMP-9 expression was detected in malignant skin epithelial neoplasms as different clinicomorphological types of basal cell carcinoma.

    Higher CXCR4 expression enhances basal cell carcinoma (BCC) invasion and angiogenesis. The underlying mechanism of increased CXCR4 expression in invasive BCC is still not well understood. To investigate the mechanisms involved in the regulation of CXCR4 expression in invasive BCC. We used qRT-PCR, RT-PCR, Western blot, and flow cytometric analyses to examine different CXCR4 levels among the clinical samples, co-cultured BCC cells and BCC cells treated with recombinant transforming growth factor-β1 (TGF-β1) and connective tissue growth factor (CTGF). Immunohistochemical studies were used to demonstrate the correlation between TGF-β1 and CXCR4 expressions. The signal transduction pathway and transcriptional regulation were confirmed by treatments with chemical inhibitors, neutralizing antibodies, or short interfering RNAs, as well as luciferase reporter activity. Invasive BCC has higher TGF-β1 and CTGF levels compared to non-invasive BCC. Non-contact dermal fibroblasts co-culture with human BCC cells also increases the expression of CXCR4 in BCC cells. Treatment with recombinant human TGF-β1, but not CTGF, enhanced the CXCR4 levels in time- and dose-dependent manners. The protein level and surface expression of CXCR4 in human BCC cells was increased by TGF-β1 treatment. TGF-β1 was intensely expressed in the surrounding fibroblasts of invasive BCC and was positively correlated with the CXCR4 expression of BCC cells. The transcriptional regulation of CXCR4 by TGF-β1 is mediated by its binding to the TGF-β receptor II and phosphorylation of the extracellular signal-related kinase 1/2 (ERK1/2)-ETS-1 pathway. TGF-β1 induces upregulation of CXCR4 in human BCC cells by phosphorylation of ERK1/2-ETS-1 pathway. Copyright © 2013 Japanese Society for Investigative Dermatology. Published by Elsevier Ireland Ltd.

  5. Immunohistochemical analysis of the mechanistic target of rapamycin and hypoxia signalling pathways in basal cell carcinoma and trichoepithelioma.

    Directory of Open Access Journals (Sweden)

    Tjinta Brinkhuizen

    Full Text Available BACKGROUND: Basal cell carcinoma (BCC is the most common cancer in Caucasians. Trichoepithelioma (TE is a benign neoplasm that strongly resembles BCC. Both are hair follicle (HF tumours. HFs are hypoxic microenvironments, therefore we hypothesized that hypoxia-induced signalling pathways could be involved in BCC and TE as they are in other human malignancies. Hypoxia-inducible factor 1 (HIF1 and mechanistic/mammalian target of rapamycin (mTOR are key players in these pathways. OBJECTIVES: To determine whether HIF1/mTOR signalling is involved in BCC and TE. METHODS: We used immunohistochemical staining of formalin-fixed paraffin-embedded BCC (n = 45 and TE (n = 35 samples to assess activity of HIF1, mTORC1 and their most important target genes. The percentage positive tumour cells was assessed manually in a semi-quantitative manner and categorized (0%, 80%. RESULTS: Among 45 BCC and 35 TE examined, expression levels were respectively 81% and 57% (BNIP3, 73% and 75% (CAIX, 79% and 86% (GLUT1, 50% and 19% (HIF1α, 89% and 88% (pAKT, 55% and 61% (pS6, 15% and 25% (pMTOR, 44% and 63% (PHD2 and 44% and 49% (VEGF-A. CAIX, Glut1 and PHD2 expression levels were significantly higher in TE when only samples with at least 80% expression were included. CONCLUSIONS: HIF and mTORC1 signalling seems active in both BCC and TE. There are no appreciable differences between the two with respect to pathway activity. At this moment immunohistochemical analyses of HIF, mTORC1 and their target genes does not provide a reliable diagnostic tool for the discrimination of BCC and TE.

    Background: Inorganic arsenic (iAs) is a potent carcinogen, but there is a lack of information about cancer risk for concentrations iAs exposure iAs metabolism. Methods: The Arsenic Health Risk Assessment and Molecular Epidemiology (ASHRAM) study, a case–control study, was conducted in areas of Hungary, Romania, and Slovakia with reported presence of iAs in groundwater. Consecutively diagnosed cases of basal cell carcinoma (BCC) of the skin were histologically confirmed; controls were general surgery, orthopedic, and trauma patients who were frequency matched to cases by age, sex, and area of residence. Exposure indices were constructed based on information on iAs intake over the lifetime of participants. iAs metabolism status was classified based on urinary concentrations of methylarsonic acid (MA) and dimethylarsinic acid (DMA). Associations were estimated by multivariable logistic regression. Results: A total of 529 cases with BCC and 540 controls were recruited for the study. BCC was positively associated with three indices of iAs exposure: peak daily iAs dose rate, cumulative iAs dose, and lifetime average water iAs concentration. The adjusted odds ratio per 10-μg/L increase in average lifetime water iAs concentration was 1.18 (95% confidence interval: 1.08, 1.28). The estimated effect of iAs on cancer was stronger in participants with urinary markers indicating incomplete metabolism of iAs: higher percentage of MA in urine or a lower percentage of DMA. Conclusion: We found a positive association between BCC and exposure to iAs through drinking water with concentrations < 100 μg/L. PMID:22436128

    Full Text Available A incidência do carcinoma basocelular vem aumentando em todos os países. Realizou-se estudo ecológico de 5169 laudos de carcinoma basocelular, da FMB-Unesp, entre janeiro/1999 e dezembro/2009. O incremento médio da incidência para o período foi de 90,6%, projetando-se um diagnóstico para cada 15 pacientes encaminhados à dermatologia. Tal tendência se manteve, mesmo quando indexada pelo número de laudos histopatológicos, movimento hospitalar, atendimentos da dermatologia e população de Botucatu.The incidence of basal cell carcinoma is increasing worldwide. An ecological study was conducted using the pathology reports from 5169 cases of basal cell carcinoma diagnosed at the Botucatu School of Medicine, Universidade Estadual Paulista Julio de Mesquita Filho (UNESP between January 1999 and December 2009. The mean increase in the incidence of basal cell carcinoma over this period was 90.6%, suggesting that one case of basal cell carcinoma could be expected for every 15 patients referred to dermatology. This trend was also found when the incidence was indexed according to the absolute number of histopathology exams, the total number of hospital consultations, the total number of dermatological consultations and the population of the town of Botucatu

    Full Text Available Objective: Nuclear expression of p53 protein is associated with a biological behavior in a variety of human malignancies. In cutaneous basal cell carcinoma (BCC, however, many studies have provided conflicting results in this regard. We aimed to determine whether there is relationship between p53 expression and different histologic subtypes of BCC, and whether it may indicate tumor aggressiveness. Materials and Methods: Biopsy samples from 66 cutaneous BCCs from 57 patients were collected. P53 expression was demonstrated by immunohistochemical staining using the anti-p53 antibody. Among them, 52 cases were also evaluated for Ki-67 antigen. Results: Immunoreactivity of p53 protein varied in the range of 0 to 100% of total tumor tissue (mean value 46.0%. The expression exceeding 5% of cancer tissue (positive staining was found in 54 BCCs (81.8%. Within this group, there were 25 cases (37.9% with low and 29 cases (43.9% with high expression. In superficial, superficial-nodular, nodular, nodular-infiltrative and infiltrative BCCs, p53 protein positivity was found in 100% (8/8, 80% (8/10, 70.4% (19/27, 88.2% (15/17 and 100% (4/4, respectively. We did not reveal a significant correlation between the extent of p53 protein expression and BCC subtypes except for nodular BCC, in which a number of negative cases (8/27, 29.6% were just above the threshold of statistical significance (P = 0.04. After merging cancers into non-aggressive and aggressive growth phenotype, no association with expression of p53 protein was found. There was no relationship between p53 protein expression and topographical sites after they have been gathered into sun-exposed and sun-protected locations. We did not observe any association between expression of p53 protein and Ki-67 antigen. Conclusion: In cutaneous BCC, the expression of p53 protein does not seem to reflect a biological behavior and tumor aggressiveness. Therefore, in a routine dermatopathological practice

    Incisional biopsy may not always provide a correct classification of histologic subtypes of basal cell carcinoma (BCC). High-frequency ultrasound (HFUS) imaging of the skin is useful for the diagnosis and management of this tumor. The main aim of this study was to compare the diagnostic value of HFUS compared with punch biopsy for the correct classification of histologic subtypes of primary BCC. We also analyzed the influence of tumor size and histologic subtype (single subtype vs. mixed) on the diagnostic yield of HFUS and punch biopsy. Retrospective observational study of primary BCCs treated by the Dermatology Department of Hospital Costa del Sol in Marbella, Spain, between october 2013 and may 2014. Surgical excision was preceded by HFUS imaging (Dermascan C © , 20-MHz linear probe) and a punch biopsy in all cases. We compared the overall diagnostic yield and accuracy (sensitivity, specificity, positive predictive value [PPV], and negative predictive value [NPV]) of HFUS and punch biopsy against the gold standard (excisional biopsy with serial sections) for overall and subgroup results. We studied 156 cases. The overall diagnostic yield was 73.7% for HFUS (sensitivity, 74.5%; specificity, 73%) and 79.9% for punch biopsy (sensitivity, 76%; specificity, 82%). In the subgroup analyses, HFUS had a PPV of 93.3% for superficial BCC (vs. 92% for punch biopsy). In the analysis by tumor size, HFUS achieved an overall diagnostic yield of 70.4% for tumors measuring 40mm 2 or less and 77.3% for larger tumors; the NPV was 82% in both size groups. Punch biopsy performed better in the diagnosis of small lesions (overall diagnostic yield of 86.4% for lesions ≤40mm 2 vs. 72.6% for lesions >40mm 2 ). HFUS imaging was particularly useful for ruling out infiltrating BCCs, diagnosing simple, superficial BCCs, and correctly classifying BCCs larger than 40mm 2 . Copyright © 2016 AEDV.

    Full Text Available Several immune-related markers have been implicated in basal cell carcinoma (BCC pathogenesis. The BCC inflammatory infiltrate is dominated by Th2 cytokines, suggesting a specific state of immunosuppression. In contrast, regressing BCC are characterized by a Th1 immune response with IFN-γ promoting a tumor suppressive activity. IL-23/Th17-related cytokines, as interleukin (IL-17, IL-23 and IL-22, play a significant role in cutaneous inflammatory diseases, but their involvement in skin carcinogenesis is controversial and is poorly investigated in BCC. In this study we investigated the expression of IFN-γ, IL-17, IL-23 and IL-22 cytokines in BCC at the protein and mRNA level and their modulation during imiquimod (IMQ treatment or photodynamic therapy (PDT. IFN-γ, IL-17, IL-23 and IL-22 levels were evaluated by immunohistochemistry and quantitative Real Time PCR in 41 histopathologically-proven BCCs (28 superficial and 13 nodular from 39 patients. All BCC samples were analyzed at baseline and 19 of 41 also during medical treatment (9 with IMQ 5% cream and 10 with MAL-PDT. Association between cytokines expression and clinico-pathological variables was evaluated. Higher levels of IFN-γ, IL-17, IL-23 and IL-22 were found in BCCs, mainly in the peritumoral infiltrate, compared to normal skin, with the expression being correlated to the severity of the inflammatory infiltrate. IFN-γ production was higher in superficial BCCs compared to nodular BCCs, while IL-17 was increased in nodular BCCs. A significant correlation was found between IFN-γ and IL-17 expression with both cytokines expressed by CD4+ and CD8+ T-cells. An increase of all cytokines occurred during the inflammatory phase induced by IMQ and at the early time point of PDT treatment, with significant evidence for IFN-γ, IL-23, and IL-22. Our results confirm the role of IFN-γ and support the involvement of IL-23/Th17-related cytokines in BCC pathogenesis and in the inflammatory response

    Basal cell carcinoma (BCC) is an indolent form of skin cancer that is rarely life threatening, but can cause significant cosmetic and functional morbidity. Surgical treatments often result in disfiguring scars, while topical therapies frequently result in recurrence. The need for a more effective nonsurgical alternative has led to the investigation of laser treatment of BCC. We have previously conducted a pilot study which showed 100% histologic clearance at high fluences. Treatments were well tolerated with no significant adverse events. The objective of this larger study was to confirm preliminary results that the 1064 nm Nd:YAG laser is a safe and effective method for treating non-facial BCC. This is an IRB-approved, prospective, multi-center study evaluating the safety and efficacy of the 1064 nm Nd:YAG laser for the treatment of BCC on the trunk and extremities. Thirty-three subjects seeking treatment for biopsy-proven BCC that did not meet the criteria for Mohs surgery were recruited. Subjects on current anticoagulation therapy, or with a history of immunosuppression were excluded. Subjects received one treatment with the 1064 nm Nd:YAG laser as follows: 5-6 mm spot, fluence of 125-140 J/cm 2 and a pulse duration of 7-10 ms. Standard excision with 5 mm clinical margins was performed at 30 days after laser treatment to evaluate clinical and histologic clearance of BCC. Standardized photographs and adverse assessments were taken at the baseline visit, immediately after laser treatment and on the day of excision. Thirty-one subjects completed the study. BCC tumors had a 90% (28 of 31 BCC tumors) histologic clearance rate after one treatment with the long-pulsed 1064 nm Nd:YAG laser. Treatments were generally well tolerated without any anesthesia. Immediate side effects included edema and erythema. At 1-month follow-up, some patients had residual crusting. No significant adverse events occurred. The 1064 nm long-pulsed Nd:YAG laser is an

    Squamous cell carcinoma (SCC) and basal cell carcinoma (BCC) are 2 skin neoplasms with distinct potentials to invasion and metastasis. Actinic keratosis (AK) is a precursor lesion of SCC. Immunohistochemistry was performed to evaluate the expression of MMP-2 and MT1-MMP in samples of BCC (n = 29), SCC (n = 12), and AK (n = 13). The ratio of positive cells to total cells was used to quantify the staining. Statistical significance was considered under the level P < .05. We found a higher expression of MMP-2 in tumor stroma and parenchyma of SCC as compared to BCC. The expression of this protein was also similar between SCC and its precursor actinic keratosis, and it was higher in the stroma of high-risk BCC when compared to low-risk BCC. MT1-MMP, which is an activator of MMP-2, was similarly expressed in all groups. Our results suggest that MMP-2 expression may contribute to the distinct invasive patterns seen in SCC and BCC. © The Author(s) 2014.

    Mohs micrographic surgery can be employed in recurrent basal cell carcinoma, although it is a time-consuming technique. Recently, ex vivo fluorescence confocal microscopy (FCM) has been employed to obtain a fast assessment of tumor margins at the bedside. In our case we successfully employed ex vivo FCM to assess the tumor margins and we treated the persistent tumor with intensity-modulated radiation therapy. Our case demonstrates that a multidisciplinary approach is very efficient in managing complex and recurrent tumors and highlights the benefits of FCM as a new technique that can be used in the surgical theater to speed up the entire procedure.

    Full Text Available Abstract Background Immunohistochemistry using antibody cocktails against basal cell specific and cancer-associated markers is important in the diagnosis of prostate carcinoma in needle biopsies. We compared the usefulness for detecting prostate carcinoma of a three-marker cocktail of antibodies to α-methylacyl-CoA racemase (AMACR, p63 and cytokeratin (CK 5 with a traditional two-marker cocktail of AMACR and p63. Methods Sixty-six prostate needle biopsies were analysed prospectively. Serial sections were immunostained with the two- and three- antibody cocktails. Blinded slides were assessed individually by two pathologists and sensitivity, specificity and kappa statistics were calculated. Results Both antibody cocktails contributed to the detection of prostate carcinoma in needle biopsies. There was an acceptable level of agreement between the pathologists for both the cocktails. Sensitivity was similar for one pathologist comparing both the cocktails (76.4% and 75.7%, but was slightly lower comparing the three-antibody with the two-antibody cocktail for the other pathologist (66.6% vs. 77.4%, respectively. Higher specificity values of 90.3% were achieved by both pathologists using three-antibody as compared with two-antibody cocktails (68.7% and 71.8%. Conclusions Antibody cocktails are important in diagnosing prostate carcinoma in needle biopsies. Adding an extra basal cell marker to the traditional two-antibody cocktail improves the specificity of detecting prostate carcinoma in limited needle biopsy material, and should be considered for routine diagnostic use.

OBJECTIVE: To characterize the clinical and anatomopathological aspects of the basal cell carcinomas diagnosed by the two services of Pernambuco region. METHODS: For the clinical study, the data were collected from the patient files and for the anatomopathological, macro and microscopic study a revision was made of the histological specimens. For determination of vertical growth, methods were used based on Clark and Breslow's histoprognostic techniques applied to malignant melanoma. RESULTS: Clinical: the highest incidence was in the feminine sex (55.7% and in the 55 to 72-year-old age group. Disease duration was highly variable, ranging from one month to 40 years, and the head was the most frequent topographical area (73.8%, mainly nasal (21.1% and zygomatic (18.5%. The nodular pigmented form (47.4% was found most frequently and the size of the lesions did not depend on the disease duration. Histologically the patterns considered based only on the parenchymal arrangements, were the adenoid, compact, plexiform Pinkus fibroepithelioma, pseudocystic, reticulated, superficial and trichoepithelioid, though predominantly the adenoid form (28.3%. The mean growth involved 2/3 of the reticular dermis (32.4%, and the deepest tumors presented intense fibroplasia. There was concomitance of several cellular types within a single tumor and melanin pigment was found mostly in the trichoepithelioid type. CONCLUSION: The clinical and anatomopathological characterization of the basal cell carcinomas is of fundamental importance at these services, where there is no major difference between groups, calling attention to behavioral definitions and propositions for the

    The distinction between cutaneous basal cell carcinoma (BCC), squamous cell carcinoma (SCC) and seborrheic keratosis (SK), which are common entities in clinical practice, can be difficult clinically and histologically. CD10 and Bcl2 antigens are important factors in tumor growth, survival and spread. The aim of the present study is to define the frequency of CD10 and Bcl2 expression in such cutaneous tumors and its relation to the clinicopathological characteristics as well as their possible diagnostic utility. CD10 and Bcl2 immunohistochemistry was performed on 30 BCC, 20 SCC and 15 SK. 93.3% of SK cases and 53.3% of BCC cases showed significant expression of CD10 in tumor cells when compared either with each other or with SCC cases (100% negative). Stromal CD10 expression was positive in 50% of BCC cases and 75% of SCC cases. Stromal CD10 expression was significantly higher in high risk BCC and BCC with infiltrating deep margins; furthermore, it showed a significant positive correlation with grade of SCC. A significant inverse correlation between CD10 expression in stromal and tumor cells of BCC was present. Bcl2 was significantly expressed in 93.3% of SK cases and 80% of BCC cases when compared with SCC cases (100% negative). It was found that for distinguishing BCC from SK, only CD10 expression in tumor cells provided a high diagnostic value with positive likelihood ratio (PLR) was 7.00. In addition, CD10 and Bcl2 expression in tumor cells could give convincing diagnostic value to distinguish SCC from SK (PLR=15.00 for each marker). Moreover, for differentiating BCC from SCC, only Bcl2 in the tumor cells could provide a high diagnostic value (PLR=5.5). In conclusion, CD10 and Bcl2 can help in differentiating cutaneous BCC from SK and SCC. The overexpression of CD10 in the stromal cells of SCC and some variants of BCC suggests the invasive properties of such tumors. Copyright © 2015 Elsevier GmbH. All rights reserved.

    In present paper, an ability to differentiate basal cell carcinoma (BCC) and healthy skin by combining multi-spectral autofluorescence imaging, principle component analysis (PCA), and linear discriminant analysis (LDA) has been demonstrated. For this purpose, the experimental setup, which includes excitation and detection branches, has been assembled. The excitation branch utilizes a mercury arc lamp equipped with a 365-nm narrow-linewidth excitation filter, a beam homogenizer, and a mechanical chopper. The detection branch employs a set of bandpass filters with the central wavelength of spectral transparency of λ = 400, 450, 500, and 550 nm, and a digital camera. The setup has been used to study three samples of freshly excised BCC. PCA and LDA have been implemented to analyze the data of multi-spectral fluorescence imaging. Observed results of this pilot study highlight the advantages of proposed imaging technique for skin cancer diagnosis.

    Basal cell carcinoma (BCC) is one of the most common types of nonmelanoma skin cancer affecting the white population; however, little is known about how the incidence varies across the U.K. To determine the variation in BCC throughout the U.K. Data from 2004 to 2010 were obtained from The Health Improvement Network database. European and world age-standardized incidence rates (EASRs and WASRs, respectively) were obtained for country-level estimates and levels of socioeconomic deprivation, while strategic health-authority-level estimates were directly age and sex standardized to the U.K. standard population. Incidence-rate ratios were estimated using multivariable Poisson regression models. The overall EASR and WASR of BCC in the U.K. were 98.6 per 100,000 person-years and 66.9 per 100,000 person-years, respectively. Regional-level incidence rates indicated a significant geographical variation in the distribution of BCC, which was more pronounced in the southern parts of the country. The South East Coast had the highest BCC rate followed by South Central, Wales and the South West. Incidence rates were substantially higher in the least deprived groups and we observed a trend of decreasing incidence with increasing levels of deprivation (P < 0.001). Finally, in terms of age groups, the largest annual increase was observed among those aged 30-49 years. Basal cell carcinoma is an increasing health problem in the U.K.; the southern regions of the U.K. and those in the least deprived groups had a higher incidence of BCC. Our findings indicate an increased incidence of BCC for younger age groups below 49 years. © 2013 British Association of Dermatologists.

    Desmoplastic trichoepithelioma (DTE), morpheaform basal cell carcinoma (BCC) and microcystic adnexal carcinoma (MAC) are sclerosing adnexal neoplasms with overlapping histopathologic features. We compared cytokeratin 15, (CK15), T-cell death-associated gene 51 (TDAG51), cytokeratin 20 (CK20) and androgen receptor (AR) in differentiating these tumors and assessed their expression in BCC subtypes. Fifteen DTE, 15 infundibulocystic BCC, 18 micronodular BCC, 18 morpheaform BCC and 6 MAC were assessed for CK15, TDAG51, CK20 and AR expression. Quantitative CK15 staining was higher in DTE compared with BCC (p < 0.0001) and MAC (p = 0.02). Quantitative TDAG51 staining was higher in DTE than BCC (p < 0.0001). The CK20+AR- immunophenotype was 100% sensitive and specific in diagnosing DTE. The CK20-AR+ immunophenotype was 95.24% specific and 83.33% sensitive for BCC. The CK20-AR- immunophenotype was 83.33% sensitive and 90.91% specific for MAC. CK15, CK20 and AR were positive in 87, 53 and 67% of infundibulocystic BCC cases, respectively. Combination of CK20 and AR best differentiated these sclerosing adnexal neoplasms. Greater positivity for CK15 and TDAG51 generally favors benign lesions. Infundibulocystic BCC has higher CK20 and lower AR immunopositivity than other BCC variants and a high degree of CK15 and TDAG51 positivity. © 2015 John Wiley & Sons A/S.

    The facial embryologic fusion planes as regions of mesenchymal and ectodermal fusion of the primordial facial processes during embryological development have been suggested to influence the spread, invasiveness, pathogenesis, and recurrence of cutaneous carcinoma. This study sought to establish whether basal cell carcinoma (BCC) originating in embryologic fusion planes has a greater propensity for earlier depth of invasion, leading to an increased rate of lesion recurrence. Facial BCCs excised in a single surgeon practice over 2 years were allocated into 2 anatomic domains according to their correlation with embryologic fusion planes. Lesion depth of invasion, surface area, and margins of excision were analyzed in conjunction with recurrence data over the following 70-80 months. Of the 331 lesions examined, 70 were located in embryologic fusion planes. No difference was found in the mean surface area and depth of invasion for lesions located in the 2 domains (P > 0.05). Ten lesion recurrences were identified, none of which were located in embryologic fusion planes. Recurrent lesions were excised with a significantly greater percentage of close and incomplete excision margins (P planes are not more invasive or at greater risk of recurrence. Excision margins seem to have the greatest influence on lesion recurrence. Because of the paucity of superfluous tissue and the cosmetic and functionally sensitive nature of these areas of embryologic fusion, specialist treatment of these lesions is recommended to ensure that adequacy of excision is not neglected at the cost of ease of closure and cosmesis.

    The aim of this study was to investigate the role of occupational and nonoccupational ultraviolet (UV)-exposure concerning the development of basal cell carcinoma (BCC). We undertook a population-based multicenter case-control study. Patients with first incident BCC (n = 836) were propensity score matched by age and sex to controls without skin cancer (n = 836). Sociodemographic characteristics, clinical characteristics, and lifetime UV-exposure were assessed by trained investigators. The differential estimation of occupational and nonoccupational UV-exposure dosages was based on validated instruments and established reference values. Associations were assessed using multivariable-adjusted conditional logistic regression models. Individuals with high levels of occupational UV-exposure were at significantly increased BCC-risk compared with individuals with low [odds ratio (OR) 1.84; 95% confidence interval (95% CI) 1.19 to 2.83 and moderate (OR 1.97; 95% CI 1.20 to 3.22) occupational UV-exposure. Nonoccupational UV-exposure was not independently associated with BCC. Skin cancer prevention strategies should be expanded to the occupational setting.

    The patient was a 77-year-old male former smoker, with history of several basal cell carcinomas (BCCs) in sun-protected areas around the waistline, who presented with another small ulceration on the anterior right upper scrotum near the base of the penis. BCC was suspected clinically and the lesion was treated with cryosurgery. The tumor recurred, became raised, and began to bleed. An excisional biopsy was performed. It showed nodular BCC surrounded by a cellular proliferation of round histiocytic cells with convoluted, lobulated and reniform nuclei and abundant cytoplasm . The patient had no history of exposure to ionizing radiation, chemotherapy, immunosuppressive medications, prior lymphoma or other malignancy. However, he spent 4 years on a ship loading coal into the furnace of a steam engine, during which he slept in adjacent quarters that were covered with coal dust. Additionally, he had a several-year history of occupational skin exposure to machine oil, oil refinery waste, sulfur waste, hydraulic fluid, and asbestos. He also reported a history of nude sunbathing. The scrotal lesion was re-excised and the patient remains disease-free more than 1 year after the diagnosis.

    Itraconazole is a triazole agent that is routinely used for treatment of nail infections and other fungal infections. Recent studies indicate that itraconazole can also inhibit the growth of basal cell carcinoma (BCC) through suppression of the Sonic Hedgehog (SHH) signaling pathway. In this study, polyglycolic acid microneedle arrays and stainless steel microneedle arrays were used for transdermal delivery of itraconazole to a human BCC model which was regenerated on mice. One-by-four arrays of 642- μm-long polyglycolic acid microneedles with sharp tips were prepared using injection molding and drawing lithography. Arrays of 85 stainless steel 800- μm-tall microneedles attached to syringes were obtained for comparison purposes. Skin grafts containing devitalized split-thickness human dermis that had been seeded with human keratinocytes transduced to express human SHH protein were sutured to the skin of immunodeficient mice. Mice with this human BCC model were treated daily for 2 weeks with itraconazole dissolved in 60% dimethylsulfoxane and 40% polyethylene glycol-400 solution; transdermal administration of the itraconazole solution was facilitated by either four 1 × 4 polyglycolic acid microneedle arrays or stainless steel microneedle arrays. The epidermal tissues treated with polyglycolic acid microneedles or stainless steel microneedles were markedly thinner than that of the control (untreated) graft tissue. These preliminary results indicate that microneedles may be used to facilitate transdermal delivery of itraconazole for localized treatment of BCC.

    A system has been developed to assess the feasibility of using motion tracking to enable pre-surgical margin mapping of basal cell carcinoma (BCC) in the clinic using optical coherence tomography (OCT). This system consists of a commercial OCT imaging system (the VivoSight 1500, MDL Ltd., Orpington, UK), which has been adapted to incorporate a webcam and a single-sensor electromagnetic positional tracking module (the Flock of Birds, Ascension Technology Corp, Vermont, USA). A supporting software interface has also been developed which allows positional data to be captured and projected onto a 2D dermoscopic image in real-time. Initial results using a stationary test phantom are encouraging, with maximum errors in the projected map in the order of 1-2mm. Initial clinical results were poor due to motion artefact, despite attempts to stabilise the patient. However, the authors present several suggested modifications that are expected to reduce the effects of motion artefact and improve the overall accuracy and clinical usability of the system.

    Basal cell carcinoma (BCC) may present as superficial subtype alone (sBCC) or superficial combined with other subtypes. The objective of this study was to compare sBCC without or with other BCC subtypes by age, sex and anatomic site. We retrospectively collected superficial BCC with the above characteristics from an Australian center during 2009 to 2014. We recorded 1528 sBCC and 1622 superficial BCC combined with other BCC subtype cases. Males numbered 2007 and females 1140. On males, head sites (forehead, cheek, nose and ear combined) compared to limb plus trunk sites displayed a higher incidence of superficial BCC combined with either nodular and or aggressive BCC subtypes (OR 13.15 CI 95% 8.9-19.5 P < .0001). On females a similar comparison also found a higher incidence of superficial BCC combined with solid subtype BCC on head sites compared to trunk and limb sites (OR 9.66 CI 95% 5.8-16.1 P < .0001). Superficial BCC alone is more likely on younger females on trunk and limb sites. Small partial biopsies reported as sBCC may miss other BCC subtypes present with higher risk on facial sites for males and females. Males had smaller proportions of superficial only subtype BCC on facial and ear sites compared to females. © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    We present protoporphyrin IX (PpIX) fluorescence measurements acquired from patients presenting with superficial basal cell carcinoma during photodynamic therapy (PDT) treatment, facilitating in vivo photobleaching to be monitored. Monte Carlo (MC) simulations, taking into account photobleaching, are performed on a three-dimensional cube grid, which represents the treatment geometry. Consequently, it is possible to determine the spatial and temporal changes to the origin of collected fluorescence and generated singlet oxygen. From our clinical results, an in vivo photobleaching dose constant, β of 5-aminolaevulinic acid-induced PpIX fluorescence is found to be 14 +/- 1 J/cm2. Results from our MC simulations suggest that an increase from our typical administered treatment light dose of 75-150 J/cm2 could increase the effective PDT treatment initially achieved at a depth of 2.7-3.3 mm in the tumor, respectively. Moreover, this increase reduces the surface PpIX fluorescence from 0.00012 to 0.000003 of the maximum value recorded before treatment. The recommendation of administrating a larger light dose, which advocates an increase in the treatment time after surface PpIX fluorescence has diminished, remains valid for different sets of optical properties and therefore should have a beneficial outcome on the total treatment effect.

    Background Non-invasive techniques to assess subclinical spread of non-melanoma skin cancer (NMSC) may improve surgical precision. High frequency ultrasound (HIFU) has shown promise to evaluate the extent of NMSC. Objective To determine the accuracy of HIFU to assess the margins of basal cell (BCC) and squamous cell carcinomas (SCC) prior to Mohs micrographic surgery (MMS). Methods We enrolled 100 patients with invasive SCC or BCC. Prior to the first stage of MMS, a Mohs surgeon delineated the intended surgical margin. Subsequently, a trained ultrasound technologist independently evaluated disease extent using the EPISCAN I-200 to evaluate tumor extent beyond this margin. The accuracy of HIFU was subsequently tested by comparison to pathology from frozen sections. Results The test characteristics of the ultrasound were sensitivity= 32%, specificity= 88%, positive predictive value= 47%, and negative predictive value=79%. Subgroup analyses demonstrated improved test characteristics for tumors larger than the median (area >1.74 cm2). Qualitative analyses showed that HIFU was less likely to identify extension from tumors with subtle areas of extension, such as small foci of dermal invasion from infiltrative SCC and micronodular BCC. Conclusions HIFU requires additional refinements to improve the preoperative determination of tumor extent prior to surgical treatment of NMSC. PMID:19018815

    A high incidence of skin cancers has been noted around the Semipalatinsk Nuclear Testing Site (SNTS) in Kazakhstan. Recently, basal cell carcinoma (BCC) susceptibility genes, human homolog of the Drosophila pathed gene (PTCH), and the xeroderma pigmentosa group A-complementing gene (XPA), have been cloned and localized on chromosome 9q22.3. To clarify the effect of low-dose irradiation on the occurrence of BCC, we used microdissection and polymerase chain reaction to identify loss of heterozygosity (LOH) at 9q22.3 using BCC samples obtained from this region. Ten Japanese samples were analyzed as controls. LOH with at least 1 marker was identified in 5 of 14 cases from around SNTS, whereas only 1 case with 1 marker was identified among the 10 Nagasaki cases. The total number of LOH alleles from SNTS (8 of 45) was significantly higher than the number from Nagasaki (1 of 26) (P = 0.03). The higher incidence of LOH on 9q22.3 in BCC from around SNTS suggests involvement of chronic low-dose irradiation by fallout from the test site as a factor in the cancers.

    Basal-cell carcinomas may show irregular, asymmetric subclinical growth. This study analyzed the efficacy of 'breadloaf' microscopy (serial sectioning) and three-dimensional (3D) microscopy in detecting positive tumor margins. Two hundred eighty-three (283) tumors (51.2%) were put into the breadloaf microscopy group; 270 tumors (48.8%) into the 3D microscopy group. The position of any detected tumor outgrowths was identified in clock face fashion. The time required for cutting and embedding the specimens and the examination of the microscopic slides was measured. Patient/tumor characteristics and surgical margins did not differ significantly. Tumor outgrowths at the excision margin were found in 62 of 283 cases (21.9%) in the breadloaf microscopy group and in 115 of 270 cases (42.6%) in the 3D microscopy group, constituting a highly significant difference (p < 0.001). This difference held true with incomplete excision of fibrosing (infiltrative/sclerosing/morpheaform) tumors [32.9% in the breadloaf microscopy group and 57.5% in the 3D microscopy group (p = 0.003)] and also with solid (nodular) tumors [16.1 and 34.2%, respectively (p < 0.001)]. The mean overall examination time required showed no important difference. In summary, for detection of tumor outgrowths, 3D microscopy has almost twice the sensitivity of breadloaf microscopy, particularly in the situation of aggressive/infiltrative carcinomas. © 2015 John Wiley & Sons A/S.

    Full Text Available In an attempt to investigate the neoplastic progression in different stages of actinic keratosis (AK, a standardized AgNOR analysis was performed in 94 cases of AK, 35 of which were associated with squamous cell carcinoma (SCC or basal cell carcinoma (BCC, and in 31 cases of SCC and 22 cases of BCC. The cases were subdivided into low- and high- AgNOR-expressing (AgNOR status AK by using the mean area of AgNORs per cell (NORA value (3.996 ?m2 as the cut-off. In AK samples, a progressive increase of the mean NORA value from Stage I to Stage IV was encountered. In addition, a significantly higher mean NORA value was found in the AK cases associated with SCC, in comparison to those without SCC; by contrast, no significant differences in the mean NORA value were noted between AK cases with or without BCC. A highly significant association between a high AgNOR quantity and the coexistence of SCC was encountered in AK; no association was appreciable between the AgNOR quantity and the co-occurrence of BCC. Moreover, when the co-existence of SCC in AK was considered as the reference point, the AK cases associated with SCC mostly (95.5% presented a high AgNOR quantity (high sensitivity, but only 57.6% of cases without SCC displayed a low AgNOR quantity (low specificity. Additionally, our data document that the standardised AgNOR analysis represents a strong negative predictor for the association between SCC and AK. Indeed, a low AgNOR quantity mostly is associated with AK cases without SCC.

    Full Text Available FUNDAMENTOS: O carcinoma basocelular é tumor constituído por diferentes tipos histológicos, que demonstram diversificado potencial de agressividade. Sabe-se que a correlação entre os tipos histológicos de carcinoma basocelular encontrados no material de biópsia pré-operatória e no material da peça cirúrgica excisional não é total. Na literatura essa correlação varia de 42,7 a 80%. OBJETIVO: Avaliar a correlação entre os tipos histológicos de carcinoma basocelular nas biópsias incisionais e respectivas peças cirúrgicas excisionais. MÉTODOS: Análise retrospectiva de 70 casos de carcinoma basocelular primário submetidos a biópsia pré-operatória e cirurgia excisional. A avaliação histológica foi feita de modo padronizado, determinando tanto o tipo histológico predominante quanto os tipos histológicos acessórios encontrados no material das biópsias préoperatórias e nas peças cirúrgicas excisionais. RESULTADOS: Houve 78,3% de correlação entre tipo histológico predominante da biópsia e peça cirúrgica e 87% de correlação entre tipo histológico predominante e/ou tipo histológico acessório da biópsia e tipo histológico predominante da peça cirúrgica. CONCLUSÃO: A biópsia pré-operatória é útil para predizer o tipo histológico predominante de carcinoma basocelular da peça cirúrgica excisional na maioria dos casos. No entanto, é importante ressaltar que, quando descrito apenas o tipo histológico predominante encontrado na biópsia, ocorre 21,7% de falha no diagnóstico.BACKGROUND: Basal cell carcinoma is a tumor with many histologic types, each one with different aggressiveness potential.

    Basal cell carcinoma (BCC) is the most common cancer worldwide, and its current treatment options are insufficient and toxic. Surprisingly, unlike several other malignancies, chemopreventive efforts against BCC are almost lacking. Silibinin, a natural agent from milk thistle seeds, has shown strong efficacy against several cancers including ultraviolet radiation-induced skin (squamous) cancer; however, its potential activity against BCC is not yet examined. Herein, for the first time, we report the efficacy of silibinin and its oxidation product 2,3-dehydrosilibinin (DHS) against BCC both in vitro and in vivo using ASZ (p53 mutated) and BSZ (p53 deleted) cell lines derived from murine BCC tumors. Both silibinin and DHS significantly inhibited cell growth and clonogenicity while inducing apoptosis in a dose- and time-dependent manner, with DHS showing higher activity at lower concentrations. Both agents also inhibited the mitogenic signaling by reducing EGFR, ERK1/2, Akt, and STAT3 phosphorylation and suppressed the activation of transcription factors NF-κB and AP-1. More importantly, in an ectopic allograft model, oral administration of silibinin and DHS (200 mg/kg body weight) strongly inhibited the ASZ tumor growth by 44% and 71% (P < 0.05), respectively, and decreased the expression of proliferation biomarkers (PCNA and cyclin D1) as well as NF-κB p50 and c-Fos in the tumor tissues. Taken together, these results provide the first evidence for the efficacy and usefulness of silibinin and its derivative DHS against BCC, and suggest the need for additional studies with these agents in pre-clinical and clinical BCC chemoprevention and therapy models. © 2014 Wiley Periodicals, Inc.

    The burden of advanced basal cell carcinoma (aBCC) is not fully understood. To compare BCC disease burden and treatment patterns for aBCC with those for non-aBCC. A retrospective, insurance claims-based study design was used. Adults with ≥2 claims associated with a BCC diagnosis (ICD-9-CM 173.x1) separated by ≥30 days on or after October 1, 2011, were classified as aBCC or non-aBCC by using an algorithm based on metastasis diagnosis, radiation therapy use, and medical oncologist/other specialist use. Non-aBCC and aBCC patients were matched 1:1 on the basis of age, sex, and region, and assigned the same index date (date of first qualifying diagnosis or event). Comparisons were made using Wilcoxon signed-rank (continuous variables) and McNemar's (categorical variables) tests. In total, 847 matched aBCC/non-aBCC patient pairs were selected (mean age 75 years; 57% men; locally advanced BCC, n = 826; metastatic BCC, n = 21). During the 12-month study period following the index date, aBCC patients had a significantly higher mean Charlson Comorbidity Index (P = .0023), significantly higher mean numbers of outpatient/dermatologist/medical oncologist visits (all P < .0001), and significantly higher mean total/medical/inpatient/outpatient/BCC treatment costs (all P < .05). This study only included information from a database on commercial insurance and Medicare claims. The algorithm criteria might have restricted patient numbers; data were not fully reflective of targeted therapy era. aBCC patients had a higher disease burden than non-aBCC patients. Cost differences were largely driven by higher BCC treatment costs, specifically radiation therapy. Copyright © 2017 American Academy of Dermatology, Inc. Published by Elsevier Inc.

    Cytology may become the diagnostic method of choice with the advent of new non-invasive treatments for non-melanoma skin cancer, as the sampling technique for cytology entails little tissue disfiguration. The aim of this study was to compare and evaluate the diagnostic performance of scrape cytology using two different cytological staining techniques, and to evaluate additional touch imprint cytology, with that of histopathology of basal cell carcinoma (BCC) and actinic keratosis (AK). We investigated 50 BCC and 28 AK histologically verified lesions, from 41 and 25 patients, respectively. Two separate skin scrape samples and one touch imprint sample were taken from each lesion. The smears were stained with Papanicolaou (Pap) or May-Grünwald-Giemsa (MGG) stains. All cytological specimens were examined in random order by pathologists without knowledge of the histology. Cytodiagnostic results were compared with the histopathological report. Scrape cytodiagnosis agreed with histopathology in 48 (Pap) and 47 (MGG) of the 50 BCC cases, and in 26 of 28 (Pap) and 21 of 26 (MGG) AK cases, yielding sensitivities of 96%, 94%, 93% and 81%, respectively. No significant difference in sensitivity between the two staining methods was found but a trend towards higher Pap sensitivity for AK was noted (P = 0.10). Touch imprint cytology confirmed histopathology in 38 of the 77 cases of BCC and AK. Cytological diagnosis with either Pap or MGG stain for BCC and AK is reliable, and differentiates well between BCC and AK. Imprint cytology proved to be non-diagnostic in half of the examined cases.

    The aim of this study was to compare morphological aspects of basal cell carcinoma (BCC) as assessed by two different imaging methods: in vivo reflectance confocal microscopy (RCM) and multiphoton tomography with fluorescence lifetime imaging implementation (MPT-FLIM). The study comprised 16 BCCs for which a complete set of RCM and MPT-FLIM images were available. The presence of seven MPT-FLIM descriptors was evaluated. The presence of seven RCM equivalent parameters was scored in accordance to their extension. Chi-squared test with Fisher's exact test and Spearman's rank correlation coefficient were determined between MPT-FLIM scores and adjusted-RCM scores. MPT-FLIM and RCM descriptors of BCC were coupled to match the descriptors that define the same pathological structures. The comparison included: Streaming and Aligned elongated cells, Streaming with multiple directions and Double alignment, Palisading (RCM) and Palisading (MPT-FLIM), Typical tumor islands, and Cell islands surrounded by fibers, Dark silhouettes and Phantom islands, Plump bright cells and Melanophages, Vessels (RCM), and Vessels (MPT-FLIM). The parameters that were significantly correlated were Melanophages/Plump Bright Cells, Aligned elongated cells/Streaming, Double alignment/Streaming with multiple directions, and Palisading (MPT-FLIM)/Palisading (RCM). According to our data, both methods are suitable to image BCC's features. The concordance between MPT-FLIM and RCM is high, with some limitations due to the technical differences between the two devices. The hardest difficulty when comparing the images generated by the two imaging modalities is represented by their different field of view. © 2012 John Wiley & Sons A/S.

OBJECTIVE: Epidemiologic characterization of the population with Non-melanoma skin cancer. METHODS: Retrospective analysis of all patients diagnosed with Non-melanoma skin cancer based on histopathologic analysis of all incisional or excisional skin biopsies performed between 2004 and 2008 in a Department of Dermatology. RESULTS: A total of 3075 Non-melanoma skin cancers were identified, representing 88% of all malignant skin neoplasms (n=3493 diagnosed in the same period. Of those, 68,3% were basal cell carcinomas. Most Non-melanoma skin cancer patients were female and over 60 years old. Of all Non-melanoma skin cancer, 81,7% (n=1443 were located in sun-exposed skin, and represented 95,1% of malignant skin neoplasms in sun-exposed skin. Non-melanoma skin cancer was the most frequent malignant skin neoplasm in most topographic locations, except for abdomen and pelvis - over 95% of all malignant skin neoplasms in the face, neck and scalp were Non-melanoma skin cancer. Basal cell carcinomas were clearly predominant in all locations, except in upper and lower limbs, lower lip and genitals, where squamous cell carcinomas represented respectively 77,7%, 77,4%, 94,7% and 95,3% of the Non-melanoma skin cancers. CONCLUSION: Being the most common skin cancer, Non-melanoma skin cancer should be under constant surveillance, in order to monitor its epidemiologic dynamics, the efficiency of preventive measures and the adaptation of the healthcare resources.FUNDAMENTOS: O cancro cutâneo não-melanoma, designação conjunta para os carcinomas basocelulares e espinhocelulares, é o tipo de neoplasia cutânea maligna mais frequente.

    Definitive radiotherapy and vismodegib, an oral inhibitor of the hedgehog pathway, are both established treatment options for locally advanced basal cell carcinomas (BCC). Both have shown good results in local tumor control; however, the effects concerning advanced tumors are often not of a lasting nature and to date no systematic data about the combination of the two modalities are available. We retrospectively analyzed four patients who received vismodegib and radiotherapy in combination. Radiation doses varied between 50.4 Gy and 66.0 Gy. Three patients had recurrent BCC. One patient had locoregional lymph node involvement. Vismodegib was taken once a day (150 mg) during the entire time of irradiation and beyond upon instructions of the attending dermatologist. In three cases a persistent complete response was observed, in one case the tumor remained stable for approximately 6 months until further tumor progression was documented. The combined therapy was well tolerated in all cases. No exceptional side effects pointing at a drug-radiation interaction were observed. The combination of vismodegib and radiation seems feasible and the initial results are promising. In our cohort, there was no increase in unexpected side effects. Further research is needed to evaluate the significance of this combined therapy. (orig.)

    Thyroid hormones (THs) mediate pleiotropic cellular processes involved in metabolism, cellular proliferation, and differentiation. The intracellular hormonal environment can be tailored by the type 1 and 2 deiodinase enzymes D2 and D3, which catalyze TH activation and inactivation respectively. In many cellular systems, THs exert well-documented stimulatory or inhibitory effects on cell proliferation; however, the molecular mechanisms by which they control rates of cell cycle progression have not yet been entirely clarified. We previously showed that D3 depletion or TH treatment influences the proliferation and survival of basal cell carcinoma (BCC) cells. Surprisingly, we also found that BCC cells express not only sustained levels of D3 but also robust levels of D2. The aim of the present study was to dissect the contribution of D2 to TH metabolism in the BCC context, and to identify the molecular changes associated with cell proliferation and survival induced by TH and mediated by D2 and D3. We used the CRISPR/Cas9 technology to genetically deplete D2 and D3 in BCC cells and studied the consequences of depletion on cell cycle progression and on cell death. Cell cycle progression was analyzed by fluorescence activated cell sorting analysis of synchronized cells, and the apoptosis rate by annexin V incorporation. Mechanistic investigations revealed that D2 inactivation accelerates cell cycle progression thereby enhancing the proportion of S-phase cells and cyclin D1 expression. Conversely, D3 mutagenesis drastically suppressed cell proliferation and enhanced apoptosis of BCC cells. Furthermore, the basal apoptotic rate was oppositely regulated in D2- and D3-depleted cells. Our results indicate that BCC cells constitute an example in which the TH signal is finely tuned by the concerted expression of opposite-acting deiodinases. The dual regulation of D2 and D3 expression plays a critical role in cell cycle progression and cell death by influencing cyclin D1-mediated

    The Nevoid Basal Cell Carcinoma Syndrome (NBCCS) is an uncommon disorder caused by a mutation in Patched, tumor suppressor gene. It is mainly characterized by numerous early onset basal cell carcinomas, odontogenic cysts of jaw and skeletal abnormalities. Due to the wide clinical spectrum, treatment and management of its modalities are not standardized and should be individualized and monitored by a multidisciplinary team. We report a typical case in a 30-year-old man with multiple basal cell carcinomas, keratotic pits of palmar creases and bifid ribs, with a history of several corrective surgeries for keratocystic odontogenic tumors, among other lesions characteristic of the syndrome.

    The metabolism of benzo(a)pyrene (BP), and its subsequent binding to DNA, and the repair of UV-induced DNA damage were studied in fibroblasts cultured from the skin of a 61-year-old male who had multiple basal cell carcinoma (BCC) (>100) on his left upper trunk. Results suggest that BP metabolism and repair of DNA are altered in tumor-bearing site (TSB) cells and that patients with this type of metabolic profile may be at higher risk of the development of cutaneous neoplasms. It is also possible that fibroblasts from tumour bearing skin undergo some as yet unexplained alteration in carcinogen metabolism as a consequence of the induction of neoplasia. (author)

    Topical photodynamic therapy (PDT) has limitations in the treatment of thick skin tumours. The aim of the study was to evaluate the effect of pre-PDT deep curettage on tumour thickness in thick (≥2 mm) basal cell carcinoma (BCC). Additionally, 3-month treatment outcome and change of tumour thickness from diagnosis to treatment were investigated. At diagnosis, mean tumour thickness was 2.3 mm (range 2.0-4.0). Pre- and post-curettage biopsies were taken from each tumour prior to PDT. Of 32 verified BCCs, tumour thickness was reduced by 50% after deep curettage (ρ≤0.001) . Mean tumour thickness was also reduced from diagnosis to treatment. At 3-month followup, complete tumour response was found in 93% and the cosmetic outcome was rated excellent or good in 100% of cases. In conclusion, deep curettage significantly reduces BCC thickness and may with topical PDT provide a favourable clinical and cosmetic short-term outcome.

    Occurrence of basal cell carcinoma (BCC) following radiotherapy for tinea capitis is well known. The aim of this study was to specify the clinical and histological features of these BCC seen in 33 patients (1995 000). Twenty seven men and six women were diagnosed with BCC. The age of onset varied between 32 an 62 years. Radiotherapy was received between 5 and 17 years of age. The interval between irradiation and the onset of carcinoma varied between 21 and 51 years. Total number of lesions was 55. Forty percent of BCC occurred on the occipital area, the number varied from 1 to 5 and the size from 2 to 45 mm. Clinically, the nodular type was found in 51% of cases. Pigment was present in 64% of cases. Histological study showed a nodular aspect in 76% and pigmentation in 63% of cases. Nodular and pigmented type were the predominant BCC occurring after radiotherapy for tinea capitis in our series. In the literature, BCC are the most frequent carcinomas occurring after radiotherapy (70-100%). Pigmentation was not described in other series. The nodular histological form was the most frequent.

    Full Text Available El epitelioma basocelular es el tumor maligno más frecuente de la piel. Su histogénesis se relaciona con la exposición actínica, por lo que su mayor incidencia se da a nivel de la cara. Normalmente la dermis actúa como factor de resistencia a la invasión tisular del tumor, situación que no se da en ciertas zonas en las que se observa un crecimiento con mayor invasión en profundidad. De estas zonas reviste importancia por su cercanía a órganos vitales el canto interno ocular, sobre todo en lesiones con extensa invasión local, por la disyuntiva del compromiso ocular y la decisión de su conservación o no. Comentamos nuestra experiencia en el tratamiento de lesiones infiltrativas de canto interno, así como la secuencia de estudio y las opciones terapéuticas.Basal cell epithelioma is the most common malignant tumor affecting the skin. It is mainly located in sun-exposed areas of the body surface due to solar actinic radiation. The facial skin is the most exposed, and the one with the highest incidence of these tumors. The dermis normally acts as a barrier against deepening, a fact which does not occur in certain areas. Among these critical sites the inner canthus region has a critical interest due to its proximity to vital organs with doubts about eye involvement and its preservation. We comment our experience in the management of infiltrative tumors of the inner canthus, diagnostic steps and therapeutical alternatives.

    Full Text Available The Gorlin-Goltz syndrome (GGS (the nevoid basal cell carcinoma syndrome—NBCCS is a rare autosomal dominant syndrome caused due to mutations in the PTCH (patched gene found on chromosome arm 9q. The syndrome, characterized by increased predisposition to develop basal cell carcinoma and associated multiorgan anomalies, has a high level of penetrance and variable expressiveness. GGS is a multidisciplinary problem, early diagnosis of which allows introduction of secondary prophylaxis and following an appropriate treatment to delay the progress of the syndrome. The following report emphasizes the need for awareness of the diagnostic criteria of this syndrome in cases with no typical skin lesions.

    Identification of early presenting signs of the Basal Cell Nevus (BCNS; synonyme Gorlin-Goltz) syndrome, which is associated with a principal triad of multiple basal cell nevi, jaw odontogenic keratocysts, and skeletal anomalies, in stomatological and neurological practices. Proposal of multidisciplinary diagnostic algorithm comprising other medical specialists, including pathology, imaging, laboratory and molecular analyses based on the study outcomes. Case report of a male patient reporting paresthesia of their lower jaw, with right facial asymmetry (maxilla and mandible) and radiological detection of large osteolytic lesions in both jaws, including a retrospective analysis of a representative Czech cohort with BCNS from within the last decade. Clinical, imaging and laboratory analyses were carried out at a national tertiary centre. A multidisciplinary clinical approach followed by surgical management lead to the identification of odontogenic cysts, which were substantiated by histological examination. DNA sequencing of the PTCH1 gene detected a c.2929dupT resulting in p. Tyr977Leufs*16 pathogenic variant. This finding confirmed the clinical and laboraoty diagnosis of BCNS. Parental DNA analysis showed that this causal genetic defect arose de novo. Surgical management and orthodontic therapy were successful. Analysis of the reported case and retrospective data analysis provided evidence that paresthesia of the lower jaw should be considered as one of the early presenting signs of this rare disorder in stomatological and neurological practice. Obtained results allowed us to formulate recommendations for diagnostic practice in stomatology and neurology.

    Full Text Available The human airway epithelium consists of 4 major cell types: ciliated, secretory, columnar and basal cells. During natural turnover and in response to injury, the airway basal cells function as stem/progenitor cells for the other airway cell types. The objective of this study is to better understand human airway epithelial basal cell biology by defining the gene expression signature of this cell population.Bronchial brushing was used to obtain airway epithelium from healthy nonsmokers. Microarrays were used to assess the transcriptome of basal cells purified from the airway epithelium in comparison to the transcriptome of the differentiated airway epithelium. This analysis identified the "human airway basal cell signature" as 1,161 unique genes with >5-fold higher expression level in basal cells compared to differentiated epithelium. The basal cell signature was suppressed when the basal cells differentiated into a ciliated airway epithelium in vitro. The basal cell signature displayed overlap with genes expressed in basal-like cells from other human tissues and with that of murine airway basal cells. Consistent with self-modulation as well as signaling to other airway cell types, the human airway basal cell signature was characterized by genes encoding extracellular matrix components, growth factors and growth factor receptors, including genes related to the EGF and VEGF pathways. Interestingly, while the basal cell signature overlaps that of basal-like cells of other organs, the human airway basal cell signature has features not previously associated with this cell type, including a unique pattern of genes encoding extracellular matrix components, G protein-coupled receptors, neuroactive ligands and receptors, and ion channels.The human airway epithelial basal cell signature identified in the present study provides novel insights into the molecular phenotype and biology of the stem/progenitor cells of the human airway epithelium.

    Full Text Available Abstract Background Non-melanoma skin cancer (NMSC, comprised of basal (BCC and squamous (SCC cell carcinomas, is the most common cancer in Caucasians. Ultraviolet radiation (UVR exposure is the most important environmental risk factor for NMSC. However, the precise relationship between UVR and the risk of NMSC is complex, and the relationship may differ by skin cancer type. Methods A case–control study was conducted among Florida residents to investigate measures of patterns (intermittent vs. continuous and timing (childhood vs. adulthood of sunlight exposure in BCC and SCC. Participants included 218 BCC and 169 SCC cases recruited from a university dermatology clinic and 316 controls with no history of skin or other cancers. Results A history of blistering sunburn (a measure of intermittent sunlight exposure was associated with both BCC (OR = 1.96, 95% CI = 1.27-3.03 and SCC (OR = 2.02, 95% CI = 1.22-3.33. Additionally, having a job in the sun for ≥3 months for 10 years or longer (a measure of continuous sunlight exposure was also associated with both BCC and SCC in our study population. With the exception of younger age at first blistering sunburn, measures of younger age at sunlight exposure tended to be associated with SCC, but not BCC risk. Conclusions Results from the current study suggest that sunlight exposure is associated with both BCC and SCC risk regardless of the pattern in which the exposure was received (i.e. intermittent vs. continuous. The data also suggest that sunlight exposure at a younger age may be more important for SCC but not BCC, however additional studies are needed to further characterize sunlight exposure-response relationships in different types of NMSC.

    premalignant lesions. OBJECTIVES: To identify the risk factors and dermatological risk markers for cutaneous malignancies. METHODS: A case-control study nested in a population-based prevalence survey was performed in adults aged 50 living in the urban area of Pelotas. In the prevalence study, a questionnaire was applied to identify possible malignant or premalignant lesions and these subjects were examined by two doctors (gold standard. A sub-sample of the persons who answered No to the questions was also sent to the Ambulatory for the same procedure. The sample was constituted of 288 persons: 74 cases and 214 controls. The number and the type of efflorescence was evaluated at the interview with the doctors. The questionnaire also investigated socioeconomic level, behavioral variables and skin examination. The measure of effect used was the Odds Ratio (OR; and to control confounding factors, logistic regression, with hierarchical pattern, was utilized. RESULTS: In the multivariate analysis, the following variables remained significant: age 80 years (OR = 10.21, white skin (OR = 4.85, blond or red hair (OR = 3.69 and risk markers: solar elastosis (OR = 4.35, cutis rhomboidalis nuchae (OR = 2.88 and more than 10 melanoses on the back of the hands (OR = 6.0. CONCLUSION: Elderly individuals, with fair skin and hair, solar elastosis, cutis rhomboidalis nuchae and a great number of melanoses on the hands, are at high risk for actinic keratosis and basal cell carcinoma.

    Gorlin-Goltz syndrome or nevoid basal cell carcinoma syndrome is a rare hereditary autosomal-dominant disorder characterized by multiple basal cell carcinomas in young patients, odontogenic keratocysts, palmar or plantar pits, calcification of the falx cerebri and skeletal malformations. This syndrome is due to mutations in PTCH1 (patched homolog 1 da Drosophila), a tumor suppressor gene. Diagnostic criteria were defined by Evans, revised by Kimonis and include major and minor criteria. The authors review in particular the neuroradiological and maxillofacial characteristics of the syndrome. The authors describe the clinical presentation of two children with Gorlin-Goltz syndrome without affected first degree relatives. In both the clinical suspicion of the syndrome is raised by the presence of multiple odontogenic cysts surgically removed. Histopathological exam revealed keratocysts. None of the patients has basal cell carcinomas but both present with skeletal anomalies, namely marked pectus deformity. The absence of major diagnostic criteria like basal cell carcinomas or palmar or plantar pits in young patients delay the early diagnosis and the correct screening for medulloblastoma, basal cell carcinomas and cardiac fibromas. Odontogenic keratocysts are the most consistent clinical finding in Gorlin-Goltz syndrome in the first one or two decades of life. These patients are very sensitive to ionizing radiation, being able to develop basal cell carcinomas and meningiomas. Treatment should accomplish the complete resection of the tumors.

    Highlights: Black-Right-Pointing-Pointer Nanoelectroablation is a new, non-thermal therapy that triggers apoptosis in tumors. Black-Right-Pointing-Pointer Low energy, ultrashort, high voltage pulses ablate the tumor with little or no scar. Black-Right-Pointing-Pointer Nanoelectroablation eliminates 99.8% of the BCC but may leave a few remnants behind. Black-Right-Pointing-Pointer Pilot clinical trials on human BCCs are ongoing and leave no remnants in most cases. -- Abstract: When skin tumors are exposed to non-thermal, low energy, nanosecond pulsed electric fields (nsPEF), apoptosis is initiated both in vitro and in vivo. This nanoelectroablation therapy has already been proven effective in treating subdermal murine allograft tumors. We wanted to determine if this therapy would be equally effective in the treatment of autochthonous BCC tumors in Ptch1{sup +/-}K14-Cre-ER p53 fl/fl mice. These tumors are similar to human BCCs in histology and in response to drug therapy . We have treated 27 BCCs across 8 mice with either 300 pulses of 300 ns duration or 2700 pulses of 100 ns duration, all at 30 kV/cm and 5-7 pulses per second. Every nsPEF-treated BCC began to shrink within a day after treatment and their initial mean volume of 36 {+-} 5 (SEM) mm{sup 3} shrunk by 76 {+-} 3% over the ensuing two weeks. After four weeks, they were 99.8% ablated if the size of the treatment electrode matched the tumor size. If the tumor was larger than the 4 mm wide electrode, multiple treatments were needed for complete ablation. Treated tumors were harvested for histological analysis at various times after treatment and exhibited apoptosis markers. Specifically, pyknosis of nuclei was evident as soon as 2 days after nsPEF treatment, and DNA fragmentation as detected via TUNEL staining was also evident post treatment. Nanoelectroablation is effective in triggering apoptosis and remission of radiation-induced BCCs with a single 6 min-long treatment of 2700 pulses.

    The Gorlin-Goltz syndrome (GGS) (the nevoid basal cell carcinoma syndrome-NBCCS) is an autosomal dominant syndrome caused by mutations found on chromosome 9. The syndrome is characterized by increased predisposition to develop a basal cell carcinoma and associated with multiorgan anomalies. To present a case of GGS and explain modern standards of care for patients with this syndrome. Authors report the case of a 36-year-old patient who was admitted to the Plastic Surgery Clinic due to numerous basal cell carcinomas. Previously patient underwent an orthopaedic, neurologic, dermatologic, stomatologic and surgery treatment due to particular anomalies which characterize this syndrome. Comprehensive interview and broadening of the diagnostics enabled to diagnose GGS and to introduce the appropriate treatment. GGS is a multidisciplinary problem and widespread knowledge of this syndrome could accelerate the diagnosis process. Early diagnosis of GGS allows to introduce the secondary prophylaxis and to apply the appropriate treatment to slow the progress of the syndrome.

    Full Text Available As caderinas compreendem uma classe de moléculas de adesão celular expressa na superfície de todas as camadas epidérmicas. A E-caderina é a principal caderina envolvida na adesão celular epitelial. A redução de sua expressão está envolvida na progressão de alguns tipos de câncer, no potencial metastático e ainda na definição do prognóstico, principalmente nos carcinomas. O carcinoma de células escamosas e o tumor de células basais são neoplasias cutâneas malignas que afetam os cães. O objetivo deste estudo foi avaliar a expressão da E-caderina no carcinoma de células escamosas (n=20 e no tumor de células basais (n=15, buscando-se relacionar sua expressão ao comportamento biológico desses tumores. Os carcinomas de células escamosas apresentaram significativa redução da expressão da molécula comparado aos tumores de células basais, quando avaliado pelo teste de Fisher (P=0,0039. Também foi observado que células neoplásicas mais diferenciadas apresentaram coloração mais intensa que as menos diferenciadas. Em conclusão, sugere-se que a expressão reduzida da E-caderina em tumores cutâneos pode indicar maior poder infiltrativo e consequentemente mau prognóstico na espécie canina.The cadherins are a group of cellular adhesion molecules that are expressed on the surface of all epidermic layer. The E-cadherin is the main cadherin involved in epithelial cellular adhesion; the decrease in its expression is related to the progression of some types of cancer, to its metastatic characteristics, and to the prognosis, specially carcinomas. The squamous cell carcinoma and the basal cells tumors are a malignant epithelial neoplasm which affects dogs. The goal of this study was to evaluate E-cadherin's expression in canine tissues that were classified as squamous cell carcinoma or basal cell tumor, and to find a correlation with the biological behavior of the tumors. The squamous cell carcinomas showed significantly

    1996-05-01

    Basal cell adenocarcinoma of salivary glands is an uncommon and recently described entity occurring almost exclusively at the major salivary glands. This report provides an overview of the clinicopathologic profile of this neoplasm by including the personal experience on the clinical features, microscopic and ultrastructural characteristics, proliferation activity, and DNA tumor patterns of 12 lesions occurring at the minor salivary glands of the head and neck region, where basal cell adenocarcinoma is probably an underecognized entity, previously reported under different designations. Basal cell adenocarcinoma predominates at the seventh decade without sex preference. The tumors affecting the minor salivary glands occur most frequently at the oral cavity (jugal mucosa, palate) and the upper respiratory tract. The prevalent histologic tumor pattern is represented by solid neoplastic aggregates with a peripheral cell palisading arrangement frequently delineated by basement membrane-like material. The neoplastic clusters are formed by two cell populations: the small dark cell type (that predominates) and a large cell type. Necrosis, either of the comedo or the apoptotic type, is a frequent finding. Perineural growth occurs in 50% of the cases and vascular permeation in 25%. Immunohistochemistry identifies a dual differentiation with a reactivity pattern indicative of ductal epithelial and myoepithelial differentiation, which can be confirmed by electron microscopy. The differential diagnosis of the neoplasm includes its benign counterpart, the basal cell adenoma, solid variant of adenoid cystic carcinoma, undifferentiated carcinoma, and basaloid squamous carcinoma. The tumors recur more frequently than lesions originating in major salivary glands. Mortality is associated with the anatomic site of the lesion, advanced stage, residual neoplasia at surgery, and tumor recurrence. The importance of recognizing basal cell adenocarcinoma outside major salivary glands is

    Thirty patients with basal cell epithelioma received high energy electron beam therapy. They were irradiated with a dose ranging from 4,800 rad (24 fractions, 35 days) to 12,000 rad (40 fractions, 57 days). Tumors disappeared in all cases. These were no disease-related deaths; in one patient there was recurrence after 2 years. We conclude that radiotherapy with high energy electron beam is very effective in the treatment of basal cell epithelioma.

    Full Text Available It has been held studying of the remote results of treatment of 80 patients sick of a bazalioma by 30 % glyciphon ointment in the Republican Oncologic Dispensary of the Ministry of Health of Republic of Tatarstan. It is established that daily use of glyciphon ointment during the 20– 30 days cures patients with primary tumours, both single, and initially-plural I and II stages, in 98,3 % cases. The preparation is effective at recidivations of bazalioma arising after radiotherapy, surgical treatment, criotherapy. The using at recidivations after the combined treatment is inexpedient. Reduction of an exposition of ointment from 24 hours till 6 hours gives good clinical effect with absence of relapses of recidivations of tumors.

  11. Learning semantic histopathological representation for basal cell carcinoma classification

    Diagnosis of a histopathology glass slide is a complex process that involves accurate recognition of several structures, their function in the tissue and their relation with other structures. The way in which the pathologist represents the image content and the relations between those objects yields a better and accurate diagnoses. Therefore, an appropriate semantic representation of the image content will be useful in several analysis tasks such as cancer classification, tissue retrieval and histopahological image analysis, among others. Nevertheless, to automatically recognize those structures and extract their inner semantic meaning are still very challenging tasks. In this paper we introduce a new semantic representation that allows to describe histopathological concepts suitable for classification. The approach herein identify local concepts using a dictionary learning approach, i.e., the algorithm learns the most representative atoms from a set of random sampled patches, and then models the spatial relations among them by counting the co-occurrence between atoms, while penalizing the spatial distance. The proposed approach was compared with a bag-of-features representation in a tissue classification task. For this purpose, 240 histological microscopical fields of view, 24 per tissue class, were collected. Those images fed a Support Vector Machine classifier per class, using 120 images as train set and the remaining ones for testing, maintaining the same proportion of each concept in the train and test sets. The obtained classification results, averaged from 100 random partitions of training and test sets, shows that our approach is more sensitive in average than the bag-of-features representation in almost 6%.

In the study group of 204 patients (146 male and 58 female with proven bronchogenic carcinoma, PNS was present in 18 (8.62% patients. The patients with PNS were divided into two groups. The first one consisted of 13 (72.2% patients with symptoms related to primary tumours while the second one consisted of 5 (27.7% patients with symptoms, at initial appearance, indicative of disorders of other organs and systems. The predominant disorder was Lambert-Eaton Syndrome, associated with small-cell carcinoma. Endocrine manifestations included: inappropriate antidiuretic hormone production syndrome (small-cell carcinoma, a gonadotropin effect with gynaecomastia and testicular atrophy (planocellular carcinoma, small-cell carcinoma, a case of Cushing Syndrome (small-cell carcinoma, and hyper-calcaemia, due to the production of the parathyroid hormone-related peptide, which was associated with planocellular carcinoma. A rare case of bilateral exophthalmos was found as PNS at adenocarcinoma. Digital clubbing and hypertrophic osteoarthropathy (HO were associated with planocellular and adenocarcinoma, while clubbing was much more common than HO, especially among women. The differences between the two groups were related to the time of PNS appearance. In the first group, PNS occurred late on in the illness, while in the second group, PNS preceded the diagnosis of BC. Alternatively, the disappearance of a clinical or a radiological manifestation of PNS after surgery or chemotherapy may be an indicator of an improvement in health or PNS may be the first sign of illness recurrence. Radiological manifestations of PNS in asymptomatic patients may serve as a useful screen for identifying primary BC. In symptomatic patients, it may be an

While the risk has been quantified, to our knowledge there is no description of how this population of patients with Lynch syndrome and upper urinary tract cancer differs from the general population with upper urinary tract cancer. We obtained retrospective data on a cohort of patients with Lynch syndrome from the Hereditary Cancer Center in Omaha, Nebraska and compared the data to those on a control general population from western Sweden. These data were supplemented by a new survey about exposure to known risk factors. Of the patients with Lynch syndrome 91% had mutations in MSH2 rather than in MSH1 and 79% showed upper tract urothelial carcinoma a mean of 15.85 years after prior Lynch syndrome-type cancer. Median age at diagnosis was 62 years vs 70 in the general population (p Lynch syndrome 51% had urothelial carcinoma in the ureter while it occurred in the renal pelvis in 65% of the general population (p = 0.0013). Similar numbers of high grade tumors were found in the Lynch syndrome and general populations (88% and 74%, respectively, p = 0.1108). Upper urinary tract tumors develop at a younger age and are more likely to be in the ureter with an almost equal gender ratio in patients with Lynch syndrome. It has high grade potential similar to that in the general population. Copyright © 2011 American Urological Association Education and Research, Inc. Published by Elsevier Inc. All rights reserved.

    The authors report two cases of bronchogenic carcinoma in patients with acquired immunodeficiency syndrome. The first patient, a ee-year-old male, developed a left hilar adenocarcinoma, with spleen and bilateral adrenal metastases. The disease progressed unfavourably, resulting in the patient's death in less than a month. The second patient, a 47-year-old male, developed a large mass in the left upper lobe, with invasion of the thoracic wall and destruction of adjacent ribs. The histopathologic study revealed a non-oat-cell carcinoma. Both patients received palliative treatment since diagnosis was established late in the course of the disease. Recent studies suggest an association between bronchogenic carcinoma and human immunodeficiency virus infection. However, an actual increase in the prevalence of bronchogenic carcinoma in HIV-positive patients remains controversial. (author)

    Screening for DNA mismatch repair (MMR) deficiency in colorectal and endometrial carcinomas identifies patients at risk for Lynch syndrome. Some patients with MMR-deficient tumors have no evidence of a germline mutation and have been described as having Lynch-like syndrome. We compared the clinicopathological features of colorectal and endometrial carcinomas in patients with Lynch-like syndrome and Lynch syndrome. Universal screening identified 356 (10.6%) of 3352 patients with colorectal carcinoma and 72 (33%) of 215 patients with endometrial carcinoma with deficient DNA MMR. Sixty-six patients underwent germline mutation analysis with 45 patients (68%) having evidence of a germline MMR gene mutation confirming Lynch syndrome and 21 patients (32%) having Lynch-like syndrome with no evidence of a germline mutation. Most patients with Lynch-like syndrome had carcinoma involving the right colon compared to patients with Lynch syndrome (93% versus 45%; P Lynch syndrome confirmed by germline mutation analysis. Synchronous or metachronous Lynch syndrome-associated carcinoma was more frequently identified in patients with Lynch syndrome compared to Lynch-like syndrome (38% versus 7%; P = .04). There were no significant differences in clinicopathological variables between patients with Lynch-like syndrome and Lynch syndrome with endometrial carcinoma. In summary, 32% of patients with MMR deficiency concerning Lynch syndrome will have Lynch-like syndrome. Our results demonstrate that patients with Lynch-like syndrome are more likely to have right-sided colorectal carcinoma, less likely to have synchronous or metachronous Lynch syndrome-associated carcinoma, and less likely to demonstrate isolated loss of MSH6 expression within their tumor.

    Lynch syndrome confers an increased risk for urothelial carcinoma (UC). Molecular subtypes may be relevant to prognosis and therapeutic possibilities, but have to date not been defined in Lynch syndrome-associated urothelial cancer. We aimed to provide a molecular description of Lynch syndrome-associated UC. Thus, Lynch syndrome-associated UC of the upper urinary tract and the urinary bladder were identified in the Danish hereditary non-polyposis colorectal cancer (HNPCC) register and were transcriptionally and immunohistochemically profiled and further related to data from 307 sporadic urothelial carcinomas. Whole genome mRNA expression profiles of 41 tumors and immunohistochemical stainings against FGFR3, KRT5, CCNB1, RB1, and CDKN2A (p16) of 37 tumors from Lynch syndrome patients were generated. Pathological data, microsatellite instability, anatomic location, and overall survival data was analyzed and compared with sporadic bladder cancer. The 41 Lynch syndrome-associated UC developed at a mean age of 61 years with 59% women. mRNA expression profiling and immunostaining classified the majority of the Lynch syndrome-associated UC as Urothelial-like tumors with only 20% being Genomically Unstable, Basal/SCC-like or other subtypes. The subtypes were associated with stage, grade, and microsatellite instability. Comparison to larger data sets revealed that Lynch syndrome-associated UC share molecular similarities with sporadic UC. In conclusion, transcriptomic and immunohistochemical profiling identifies a predominance of the Urothelial-like molecular subtype in Lynch syndrome and reveals that the molecular subtypes of sporadic bladder cancer are relevant also within this hereditary, mismatch-repair defective subset.

    Gorlin-Goltz syndrome is an uncommon hereditary condition caused by mutations in the PTCH1 gene causing a wide range of developmental abnormalities. Multiple basal cell carcinomas, palmoplantar pits and jaw cysts are cardinal features. Many clinicians are unfamiliar with the different manifestations and the fact that patients are especially sensitive to ionizing radiation. This was a retrospective analysis of patients with Gorlin-Goltz syndrome seen at the Department of Dermatology and Allergy Centre or at Department of Plastic Surgery, Odense University Hospital, Denmark, in the period from 1994 to 2013. A total of 17 patients from eight families fulfilled the diagnostic criteria. In all, 14 patients had basal cell carcinomas, 12 patients had jaw cysts and ten patients had calcification of the falx cerebri. Other clinical features were frontal bossing, kyphoscoliosis, rib anomalies, coalitio, cleft lip/palate, eye anomalies, milia and syndactyly. In one family, medulloblastoma and astrocytoma occurred. Traditional treatment principles of basal cell carcinomas were used including radiotherapy performed in six patients. PTCH1 mutations were identified in five families and none of these mutations had previously been described. The patient cohort illustrates classic and rare disease manifestations. It is necessary to remind clinicians that radiation therapy in Gorlin-Goltz syndrome is relatively contraindicated. Today, mutation analysis can be used for confirmation of the diagnosis and for predictive genetic testing. Patients should be offered genetic counselling and life-long surveillance. not relevant. not relevant.

    Nevoid basal cell carcinoma syndrome is a syndrome with wide variety of manifestations ranging from oral lesions to skeletal deformities. It calls for due responsibility of maxillofacial surgeon to diagnose the syndrome because very often they are the first health professionals to see the patient for the treatment of keratocystic odontogenic tumor. Keratocystic odontogenic tumor has been the topic of numerous investigators, is known for its potentially aggressive behavior, significant rate of recurrences. KCOT often occurs as a solitary lesion, in some instances multiple keratocysts may occur in association with a syndrome called Gorlin-Goltz syndrome (nevoid BCC, jaw cyst bifid rib basal cell nevus syndrome). Here, we present a case of multiple keratocysts in the mandible in association with skeletal, ocular, cutaneous anomalies in the given clinical scenario, which has profound relevance in the clinical dental practice.

    To date, cervical carcinoma complicated with Cushing's syndrome were all diagnosed as small cell carcinoma histo- logically, but not adenosquamous carcinoma. Here the authors present the diagnosis, management, and prognosis of a case of melanocytic cervical adenosquamous carcinoma complicated with Cushing's syndrome. A 28-year-old woman was admitted with the chief complaint of post-coital bleeding for one month. Gynecological examination revealed a nodular yellowish-pigmented vegetation (6x5 cm) on the cervix. Laboratory findings proved the diagnosis of Cushing's syndrome. Histopathological diagnosis showed the adenosquamous carcinoma with melanoma differentiation. Immunohistochemical stainings for melanoma A and anti- adrenocorticotropic hormone (ACTH) were positive in the majority of the tumor cells, which indicated that this melanocytic cervical carcinoma lesion was the source of ectopic ACTH production resulting in Cushing's syndrome. This is a unique case of a rare type of cervical carcinoma.

    Full Text Available Basal cell adenoma (BCA of the salivary glands is a rare benign tumor resembling pleomorphic adenoma, but with a prominent basaloid cell layer. The majority of these tumors arise in the parotid glands and account for only 1% of all salivary gland epithelial tumors. We report one such case of a swelling in the floor of the mouth in a 55-year-old female where BCA is the most likely diagnosis; however, histological variation does show a similarity to malignant adenoid cystic carcinoma, thereby making the diagnosis difficult. The incidence of malignancy is relatively higher in the submandibular, sublingual and minor salivary glands. Approximately, 85% of sublingual gland tumors are malignant. Thus, we should be more careful when making a diagnosis in minor salivary gland tumors. [Arch Clin Exp Surg 2016; 5(4.000: 246-249

    2009-12-01

    Full Text Available The degree of DNA-instability as revealed by immunohistochemical staining with anti-cytidine antibody after acid hydrolysis (DNA-instability test has been recently used as a marker of malignancy. This technique was applied to examine 17 skin tissue samples of Bowen’s disease, 47 of actinic keratosis, 15 of squamous cell carcinoma, 5 of seborrheic keratosis, and 10 of normal skin. All benign neoplastic cells of seborrheic keratosis and normal epidermal cells were negative. On the other hand, all cancer cells were positive with the DNA-instability test, indicating their malignancy, but all basal cells in Bowen’s disease were completely negative. Compatible with this result, the basal cells in Bowen’s disease were characteristically normal as evident in other histochemical examinations. Thus, they were negative with p53 immunohistochemistry, with normal signals of chromosome 17 in situ hybridisation and argyrophilic nucleolar organiser region, and showed slightly enhanced proliferative activity as revealed by proliferating cell nuclear antigen immunohistochemistry. Immunohistochemical staining with 34 ß E12 (monoclonal antibody against cytokeratins 1, 5, 10, and 14, which stains all normal epidermal keratinocytes including basal cells, showed that only the basal cells of Bowen’s disease stained strongly and homogeneously, while all cancer cells in the upper layers of Bowen’s disease and all layers of actinic keratosis were only sporadically or weakly stained. Staining with 34 ß B4 (monoclonal antibody against cytokeratin 1, which recognises the whole epidermis except for the basal layer in the normal epidermis, showed that the basal cells in the Bowen’s disease were completely negative, and lower layer cells in the actinic keratosis and upper layer cells in Bowen’s disease were only sporadically stained positive, although the superficial layer cells in actinic keratosis stained strongly and homogeneously.

    Gorlin-Goltz syndrome is a rare multisystemic disease inherited in an autosomal dominant pattern. It is characterized by numerous basal cell carcinoma of the skin, jaw cysts, and skeletal anomalies such as frontal bossing, vertebral anomalies, palmoplantar pits, and falx cerebri calcification. There is a tendency to tumors including medullablastoma, fibroma, rabdomyoma, leiomyosarcoma etc.. The diagnosis is based on major and minor clinical and radiologic criteria. Early diagnosis and treatment are of utmost importance in reducing the severity of long-term sequelae of this syndrome. In this article, we present a 15-year-old boy who was admitted to our clinic with brown-black papules and plaques on his scalp and was thought to have Gorlin-Goltz syndrome. He had a history of medulloblastoma that was treated with surgical resection followed by cranial radiotherapy and unilateral retinoblastoma. We present this case, because association of Gorlin-Goltz syndrome and retinoblastoma has not been described previously in the literature and we aimed to draw attention to radiation-induced basal cell carcinomas.

    Gorlin and Goltz described a syndrome in which multiple basal cell carcinomas, odontogenic keratocysts and bifid ribs occurred in combination. The jaw keratocysts are a consistent feature of 'Gorlin-Goltz' or naevoid basal cell carcinoma syndrome. Central nervous system and ocular involvement occurred together with the fairly typical facial features of frontal bossing and hypertelorism. This case report documents the pathology associated with an impacted maxillary canine tooth in a boy with Gorlin-Goltz syndrome. The patient presented for investigation of the failure of eruption of the right permanent maxillary canine tooth. Radiographic investigation showed the presence of a well circumscribed radiolucency located around the crown of an impacted right maxillary canine tooth. The patient's medical history revealed a medulloblastoma that was treated 13 years ago. The right maxillary canine tooth and associated peri-coronal tissue were removed under general anaesthetic. A diagnosis of a keratocystic odontogenic tumour with an associated adenomatoid odontogenic tumour was made. The common differential diagnoses for a peri-coronal radiolucency in the maxilla that need to be considered by dentists include a dentigerous cyst, follicular keratocystic odontogenic tumour and adenomatoid odontogenic tumour. A rare case of both keratocystic odontogenic tumour and associated follicular adenomatoid odontogenic tumour is described in a patient with naevoid basal cell carcinoma syndrome. © 2014 Australian Dental Association.

    Full Text Available A malignant transformation is known to occur in many nevi such as a sebaceous nevus or a basal cell nevus, but a verrucous epidermal nevus has only rarely been associated with neoplastic changes. Keratoacanthoma, multifocal papillary apocrine adenoma, multiple malignant eccrine poroma, basal cell carcinoma and cutaneous squamous cell carcinoma (CSCC have all been reported to develop from a verrucous epidermal nevus. CSCC has also been reported to arise from other nevoid lesions like a nevus comedonicus, porokeratosis, a sebaceous nevus, an oral sponge nevus and an ichthyosiform nevus with CHILD syndrome. Here we report a case of progressive poorly differentiated CSCC arising from a localized verrucous epidermal nevus, which caused both spinal cord and brain metastasis.

    Full Text Available Renal cell carcinoma is the ninth most common malignancy. The commonest histopathological type is clear cell carcinoma. The occurrence of sarcomatoid carcinoma is very rare and confers a very poor prognosis. Only 10-20% patients present with paraneoplastic syndromes. Out of the common paraneoplastic syndromes, leucocytosis is one of the least reported. Here, we present a case of sarcomatoid carcinoma of kidney who presented with low-grade fever and leucocytosis, followed by a short review of literature.

    2015-01-01

    Full Text Available Keratocystic odontogenic tumors (KCOTs are one of the most frequent features of nevoid basal cell carcinoma syndrome (NBCCS. The condition is linked with mutation in the PTCH gene. Partial expression of the gene may result in occurrence of multiple recurring odontogenic keratocysts (OKCs. Although KCOTs are common in clinical practice, simultaneous occurrence of multiple cysts in both the maxilla and mandible of a patient is rare. These patients have early propensity to develop multiple neoplasms like basal cell carcinoma and medulloblastoma. Hence, early diagnosis and treatment is of utmost importance in reducing the severity of the long-term sequelae of NBCCS. We report a rare case of multiple KCOTs in a non-syndromic male patient, with emphasis on its diagnosis, radiographic features, and treatment.

  6. Endothelial MMP14 is required for endothelial-dependent growth support of human airway basal cells

    2015-01-01

    ABSTRACT Human airway basal cells are the stem (or progenitor) population of the airway epithelium, and play a central role in anchoring the epithelium to the basement membrane. The anatomic position of basal cells allows for potential paracrine signaling between them and the underlying non-epithelial stromal cells. In support of this, we have previously demonstrated that endothelial cells support growth of basal cells during co-culture through vascular endothelial growth factor A (VEGFA)-mediated signaling. Building on these findings, we found, by RNA sequencing analysis, that basal cells expressed multiple fibroblast growth factor (FGF) ligands (FGF2, FGF5, FGF11 and FGF13) and that only FGF2 and FGF5 were capable of functioning in a paracrine manner to activate classical FGF receptor (FGFR) signaling. Antibody-mediated blocking of FGFR1 during basal-cell–endothelial-cell co-culture significantly reduced the endothelial-cell-dependent basal cell growth. Stimulation of endothelial cells with basal-cell-derived growth factors induced endothelial cell expression of matrix metallopeptidase 14 (MMP14), and short hairpin RNA (shRNA)-mediated knockdown of endothelial cell MMP14 significantly reduced the endothelial-cell-dependent growth of basal cells. Overall, these data characterize a new growth-factor-mediated reciprocal ‘crosstalk’ between human airway basal cells and endothelial cells that regulates proliferation of basal cells. PMID:26116571

    Full Text Available Gorlin-Goltz syndrome is an uncommon autosomal dominant inherited disorder, which is characterized by multiple odontogenic Keratocysts and basal cell carcinomas, skeletal, dental, ophthalmic, and neurological abnormalities, intracranial ectopic calcifications of the falx cerebri, and facial dysmorphism. Pathogenesis of the syndrome is attributed to abnormalities in the long arm of chromosome 9 (q22.3-q31 and loss or mutations of human patched gene (PTCH1 gene. Diagnosis is based upon established major and minor clinical and radiological criteria and ideally confirmed by deoxyribo nucleic acid analysis. We report a case of a 9-year-old girl presenting with three major and one minor feature of Gorlin-Goltz syndrome. Radiologic findings of the syndrome are easily identifiable on Orthopantomogram, chest X-ray, and Computed tomography scans. These investigations prompt an early verification of the disease, which is very important to prevent recurrence and better survival rates from the coexistent diseases.

    We describe a patient with Klinefelter's syndrome associated with multi-focal breast carcinoma and Paget's disease of the nipple. Reviewing the 16 previously documented cases in the world literature, it is apparent that patients with this syndrome have an increased incidence of breast carcinoma. There is no evidence to date to suggest that such tumour is morphologically or biologically different from breast cancer in females and normal men.

    Gorlin-Goltz Syndrome, also known as nevoid basal cell carcinoma syndrome (NBCCS), is an autosomal dominant trait caused due to mutations in the patched tumor suppressor gene (PTCH) gene found on the long arm of chromosome 9. The syndrome is characterized by the presence of odontogenic keratocysts (OKCs), basal cell carcinomas, and skeletal malformations. Early diagnosis of the syndrome can be done by pedodontist as OKC is one of the early manifestations of the syndrome. Early diagnosis and treatment is important for long-term prognosis of the syndrome by reducing the severity of cutaneous carcinomas and deformities due to jaw cyst. The present case describes an 11-year-old patient with some typical features of NBCCS, which were diagnosed through its oral and maxillofacial manifestations. This case emphasizes the importance of pedodontist in early recognition of the syndrome. Tandon S, Chauhan Y, Sharma M, Jain M. Gorlin-Goltz Syndrome: A Rare Case Report of a 11-Year-Old Child.

    Gorlin-Goltz syndrome is an uncommon disorder transmitted through autosomal dominant inheritance. This syndrome is characterized by multiple odontogenic keratocysts, along with congenital skeletal anomalies and basal cell carcinomas. A 16-year-old girl was admitted with a complaint of swelling on the lower jaw. She had multiple basal cell nevi on both hands. Multiple lytic bone lesions on radiographs were defined as odontogenic keratocysts following the biopsy. The patient was referred to the Department of Physical Medicine and Rehabilitation for detailed musculoskeletal evaluation. Adam's forward bend test revealed a hump on the right side representing right thoracic scoliosis. Cervical kyphosis, thoracic lordosis and scoliosis, bifid rib and sacral and lumbar spina bifida on plain radiographs led to the diagnosis of Gorlin-Goltz syndrome. Since early diagnosis may provide optimum surveillance for related neoplasms, it is of paramount importance for pediatricians as well as physicians dealing with the musculoskeletal system to be aware of this rare condition.

    Patients with Lynch syndrome are at risk for upper tract urothelial carcinoma. We sought to identify the incidence and most reliable means of point of care screening for Lynch syndrome in patients with upper tract urothelial carcinoma. A total of 115 consecutive patients with upper tract urothelial carcinoma without a history of Lynch syndrome were universally screened during followup from January 2013 through July 2016. We evaluated patient and family history using AMS (Amsterdam criteria) I and II, and tumor immunohistochemistry for mismatch repair proteins and microsatellite instability. Patients who were positive for AMS I/II, microsatellite instability or immunohistochemistry were classified as potentially having Lynch syndrome and referred for clinical genetic analysis and counseling. Patients with known Lynch syndrome served as positive controls. Of the 115 patients 16 (13.9%) screened positive for potential Lynch syndrome. Of these patients 7.0% met AMS II criteria, 11.3% had loss of at least 1 mismatch repair protein and 6.0% had high microsatellite instability. All 16 patients were referred for germline testing, 9 completed genetic analysis and counseling, and 6 were confirmed to have Lynch syndrome. All 7 patients with upper tract urothelial carcinoma who had a known history of Lynch syndrome were positive for AMS II criteria and at least a single mismatch repair protein loss while 5 of 6 had high microsatellite instability. We identified 13.9% of upper tract urothelial carcinoma cases as potential Lynch syndrome and 5.2% as confirmed Lynch syndrome at the point of care. These findings have important implications for universal screening of upper tract urothelial carcinoma, representing one of the highest rates of undiagnosed genetic disease in a urological cancer.

    Increased risk for upper tract urothelial carcinoma is described in patients with Lynch syndrome, caused by germline mutations in mismatch repair genes. We aimed to identify the frequency of mismatch repair protein loss in upper tract urothelial carcinoma and its potential for identifying an association with Lynch syndrome. We queried our database to identify upper tract urothelial carcinomas. Patients were cross-referenced for history of colorectal carcinoma or other common Lynch syndrome-associated neoplasms to enrich for potential Lynch syndrome cases. Tumor histopathologic characteristics were reviewed and each case was analyzed for loss of mismatch repair proteins, MLH1, MSH2, MSH6, and PMS2, by immunohistochemistry. Of 444 patients with upper tract urothelial carcinoma, a subset of 215 (encompassing 30 with upper tract urothelial carcinoma and another common Lynch syndrome-associated neoplasm) was analyzed for loss of mismatch repair protein expression. Of 30 patients with Lynch syndrome-associated neoplasms, six had documented Lynch syndrome, including two with Muir-Torre syndrome. Mismatch repair protein loss was identified in 7% of total upper tract urothelial carcinomas and 30% of patients with Lynch syndrome-associated neoplasms (including all patients with Lynch syndrome/Muir-Torre syndrome). Of patients without history of Lynch syndrome-associated neoplasms, 5 of 184 (2.7%) had loss of mismatch repair protein expression. Twelve cases with mismatch repair protein loss demonstrated loss of MSH2 and MSH6, and 2 had isolated loss of MSH6. MLH1 and PMS2 expression were consistently retained. Although increased intratumoral lymphocytes, inverted growth, pushing tumor-stromal interface, and lack of nuclear pleomorphism were more commonly seen in cases with mismatch repair protein loss, only intratumoral lymphocytes and presence of pushing borders were statistically significant. MLH1 and PMS2 testing appear to have little utility in upper tract urothelial

    'Keratinocyte cancer' is now the preferred term for the most commonly identified skin cancers basal cell carcinoma (BCC) and cutaneous squamous cell carcinoma (cSCC), which were previously commonly categorised as non-melanoma skin cancers (NMSC). Keratinocyte cancer (KC) represents about 95% of malignant skin tumours. Lifestyle changes have led to increased exposure to the sun, which has, in turn, led to a significant increase of new cases of KC, with a worldwide annual incidence of between 3% and 8%. The successful use of preventive measures could mean a significant reduction in the resources used by health systems, compared with the high cost of the treatment of these conditions. At present, there is no information about the quality of the evidence for the use of these sun protection strategies with an assessment of their benefits and risks. To assess the effects of sun protection strategies (i.e. sunscreen and barrier methods) for preventing keratinocyte cancer (that is, basal cell carcinoma (BCC) and cutaneous squamous cell carcinoma (cSCC) of the skin) in the general population. We searched the following databases up to May 2016: the Cochrane Skin Group Specialised Register, CENTRAL, MEDLINE, Embase, and LILACS. We also searched five trial registries and the bibliographies of included studies for further references to relevant trials. We included randomised controlled clinical trials (RCTs) of preventive strategies for keratinocyte cancer, such as physical barriers and sunscreens, in the general population (children and adults), which may provide information about benefits and adverse events related to the use of solar protection measures. We did not include trials focused on educational strategies to prevent KC or preventive strategies in high-risk groups. Our prespecified primary outcomes were BCC or cSCC confirmed clinically or by histopathology at any follow-up and adverse events.

  18. Hereditary syndromes with enhanced radiosensitivity

    Lohmann, D.

    2000-01-01

    Sensitivity to ionizing radiation is modified by heritable genetic factors. This is exemplified by heritable disorders that are characterized by predisposition to the development of neoplasms. Cells derived from patients with ataxia telangiectasia, Nijmegen breakage syndrome and ataxia telangiektasia-like disorder show a markedly changed reaction to exposure to ionizing radiation. Correspondingly, at least in patients with ataxia telangiectasia, an enhanced radiosensitivity that is of clinical importance has been observed. In addition to these recessive disorders, some autosomal dominant cancer predisposition syndromes are associated with increased radiosensitivity. As cells from these patients still have a normal allele (that is dominant over the mutant allele), the cellular phenotype is most often normal. Specifically, there is no overtly altered reaction in response to ionizing radiation. Nevertheless, two dominant cancer predisposition syndromes, namely hereditary retinoblastoma and naevoid basal cell carcinoma syndrome, are associated with a enhanced radiosensitivity as indicated by increased development of tumors following radiation therapy.

    Gorlin-Goltz syndrome is a rare hereditary disease that can have negative effects on one's quality of life. The main clinical features are multiple nevoid basal cell carcinomas, odontogenic keratocysts, congenital skeletal abnormalities, calcification of the falx cerebri, facial dysmorphism, and skin depressions (pits) on the palms and soles. Diagnosis is based on major and minor clinical and radiological criteria and can be confirmed by DNA analysis. This article describes the case of a child with Gorlin-Goltz syndrome and outlines the clinical manifestations of the disease.

    Gorlin-Goltz syndrome (GGS), also known as nevoid basal cell carcinoma syndrome (MIM 109 400), is a rare genetic condition with a prevalence between 1/56 000 and 1/256 000. Clinical presentation is usually characterized by multiple basal cell carcinomas, odontogenic jaw keratocysts, palmar or plantar pitting and skeletal anomalies. It is furthermore associated with the development of various tumors beside basal cell carcinoma, among which medulloblastoma is the most frequent. Increased incidence of other mesenchymal neoplasms, however, is also well known: recently the first adult case of gastric leiomyoma in GGS was reported, and the inclusion of "fibromas and leiomyomas of other organs" in the minor criteria for the diagnosis was suggested. We report the first case of a pediatric patient with GGS who also developed a gastric leiomyoma: the present case illustrates the need for this change to the diagnostic criteria to encompass the highly variable presentations and phenotype in GGS. © 2015 Japan Pediatric Society.

    A 32-year-old woman in whom basal cell epithelioma (BCE) arose on the P-32 irradiated area is reported. At the age of 2, the patient had received superficial irradiation with P-32 for hemangioma simplex on the right precordial site. A black, ill-defined mass has occurred and gradually increased 3 years earlier. Chronic radiodermatitis characterized by teleangiectasis and skin atrophy was seen in the area surrounding the mass, which corresonded to that exposed to P-32. Histopathological examination leads to the diagnosis of BCE developing in part of chronic radiodermatitis. Review of the literature shows 3 cases of squamous cell carcinoma of the skin resulting from P-32 therapy. This is the first report on a patient with BCE resulting from irradiation with P-32.

    Ectopic adrenocorticotropic hormone (ACTH) is rarely secreted by neuroendocrine tumors. Although neuroendocrine tumors may occur at any site in the gastrointestinal system, they very rarely occur in the ampulla of Vater and have a poor prognosis. The present study described the first Cushing's syndrome as a result of ectopic ACTH arising from the ampulla of Vater neuroendocrine carcinoma. A 69-year-old female was admitted with clinical features of Cushing's syndrome, confirmed biochemically by hypokalemia, and elevated levels of ACTH and cortisol. In further investigations, a tumor of the ampulla of Vater and liver metastases were detected. Pathological analysis of the biopsy confirmed a neuroendocrine carcinoma, which was immunohistochemically positive for chromogranin A, synaptophysin, cluster of differentiation 56 and ACTH. Therefore, the present study diagnosed a functional and metastatic neuroendocrine carcinoma of the ampulla of Vater with ectopic ACTH production causing Cushing's syndrome. The patient succumbed to mortality 4 months later, despite administration of combined chemotherapy with irinotecan and cisplatin.

    A 66-year-old woman with Pendred's syndrome underwent a partial thyroidectomy when she was 17 years old. At the age of 52 years, she had a second thyroid operation because of hyperthyroidism due to a toxic multinodular goiter with a mediastinal extension consisting of several separate nodules. Five years later a hyperfunctioning metastatic follicular carcinoma was diagnosed histologically. After treatment with radioactive iodine, the patient was well. To the authors' knowledge, this is the first description of a metastatic follicular thyroid carcinoma in Pendred's syndrome and the first report of hyperthyroidism occurring after malignant degeneration of a dyshormonogenetic goiter.

    Lynch syndrome, a hereditary cancer syndrome, occurs because of germline mutations in at least one of four DNA mismatch repair genes (MutL Homolog 1 (MLH1), MutS Homolog 2 (MSH2), MutS Homolog 6 (MSH6), and PMS1 Homolog 2 (PMS2)). The disorder is associated with colorectal, endometrial, and other epithelial malignancies, but not cervical cancer. We report a woman with Lynch syndrome with synchronous cervical cancer. This is the first report of Lynch syndrome-related clear cell carcinoma of the cervix, which indicates the possibility of an association between cervical cancer and Lynch syndrome. Suitable genetic tests are required to determine whether common genetics can account for synchronous or subsequent malignancies in Lynch syndrome patients and their families. Such knowledge will also enhance our understanding of the genetic mechanisms governing the development of apparently unrelated cancers. PMID:29587389

  8. Expression of basal cell marker revealed by RAM11 antibody during epithelial regeneration in rabbits.

    Full Text Available RAM11 is a mouse monoclonal anti-rabbit macrophage antibody recognizing connective tissue and vascular macrophages. Our previous report showed that RAM11 reacted with basal cells of stratified squamous epithelia of rabbit skin, oral mucosa and esophagus. The aim of the present study was to follow the appearance of RAM11 immunoreactivity in basal cells of regenerating oral epithelium in rabbits. No RAM11 immunostaining was observed in the regenerating epithelium examined on days 1 and 3 of wound healing. A weak immunofluorescence first appeared on day 7 in single basal cells and 32% of RAM11- positive basal cells were observed on day 14. These findings indicate that expression of the antigen recognized by RAM11 antibody is a transient event in the differentiation of oral keratinocytes which not always occurs during epithelial repair, although it is a constant feature of epithelial turnover in mature epithelium. Therefore this antigen can be regarded as basal cell marker only in mature stratified squamous epithelia.

    In the normal mammary gland, the basal epithelium is known to be bipotent and can generate either basal or luminal cells, whereas the luminal epithelium has not been demonstrated to contribute to the basal compartment in an intact and normally developed mammary gland. It is not clear whether cellular heterogeneity within a breast tumor results from transformation of bipotent basal cells or from transformation and subsequent basal conversion of the more differentiated luminal cells. Here we used a retroviral vector to express an oncogene specifically in a small number of the mammary luminal epithelial cells and tested their potential to produce basal cells during tumorigenesis. This in-vivo lineage-tracing work demonstrates that luminal cells are capable of producing basal cells on activation of either polyoma middle T antigen or ErbB2 signaling. These findings reveal the plasticity of the luminal compartment during tumorigenesis and provide an explanation for cellular heterogeneity within a cancer.

    A 81-year-old male had perioral radiodermatitis of 50 years' duration which was associated with Bowen's disease and basal cell epitheliomas since age 59 years. One of those basal cell epitheliomas treated with topical 5-FU and bleomycin ointments increased to form an ulcer of 25 x 15mm in size nearby the right side of nose, accompanying with a fistule to the oral cavity while he hesitated to visit the hospital. 5-FU was intralesionally injected into the tumor. After the injections in total dose of 6,550mg the ulcer got epithelized and the biopsy could not reveal the tumor cell. The case proves the effectiveness of intralesional injection of 5-FU for basal cell epithelioma which avoids the surgical excision.

    Full Text Available Basal cell epithelioma is one of the most frequent malignant skin neoplasms. Angiogenesis plays an important part in the development of basal cell epithelioma. The article presents a review of the angiogenesis of this tumor with the help the immunohistochemistry analysis using CD31 and CD34 markers. The authors established a reliable relationship between the number of vessels expressing CD31 and those expressing CD34 in the superficial and nodular forms of the tumor as well as superficial, multi-center, nodular and infiltrative basal cell epitheliomas. A comparison of the number of vessels expressing CD31 and CD34 markers in different histological types made revealed a trend to their growth in the infiltrative type vs. superficial, multi-center and nodular ones.

    Lynch syndrome (LS) is an autosomal dominant condition that predisposes to colorectal cancer and specific other tumors. Extracolonic tumors occur mainly in the endometrium, stomach, ovary, small intestine and urinary tract. The presence of rare tumors in patients belonging to families who have Lynch syndrome is always interesting, because the question arises whether these tumors should be considered as a coincidence or are related with the syndrome. In this last case, they are also the result of the defect in the mismatch repair system, opening the possibility of extending the tumor spectrum associated with the syndrome. Here we describe a patient from a Lynch syndrome family with a germline mutation c.2063T>G (p.M688R) in the MSH2 gene, who developed an adrenal cortical carcinoma, a tumor not usually associated with LS. We analyzed the adrenocortical tumour for microsatellite instability (MSI), LOH and the presence of the germline c.2063T>G (M688R) mutation. The adrenal cortical carcinoma showed the MSH2 mutation, loss of heterozygosity of the normal allele in the MSH2 gene and loss of immunohistochemical expression for MSH2 protein, but no microsatellite instability. Additionally, the adrenal cortical carcinoma did not harbour a TP53 mutation. The molecular study indicates that this adrenal cortical cancer is probably due to the mismatch repair defect.

    Gorlin-Goltz syndrome, also known as nevoid basal cell carcinoma syndrome, is caused by genetic alteration produced by a mutation in the 'patched' tumour suppressor gene, and is inherited in a dominant autosomal way. Although sporadic cases have been found, this syndrome has rarely been reported in twin patients. The syndrome is characterised by a wide range of developmental abnormalities and has a predisposition to neoplasms such as multiple pigmented basal cell carcinomas and keratocysts in jaws; it also has other features such as palmar and/or plantar pits and calcification of falx cerebri. Owing to the critical oral and maxillofacial manifestations of this syndrome, it is important to recognise its characteristics in order to make a diagnosis, and to plot early preventive treatment and establish the right genetic evidence. Based on a combination of imaging, clinical and histopathological findings, we present a diagnosed case of Gorlin-Goltz syndrome in 18-year-old twin brothers. All cystic lesions were enucleated and 1 year follow-up showed no recurrence. 2015 BMJ Publishing Group Ltd.

    Full Text Available A 3.5-year-old wild born cheetah (Acinonyx jubatus, living in a large enclosure on a private Namibian farm, developed a large exophytic nodular neoplasm in its skin at the height of the left shoulder blade. We describe the clinical appearance, the surgical removal, and histological examination of the tumor, which was diagnosed as a moderately pigmented benign basal cell tumor. A three-year follow-up showed no evidence of recurrence after the surgery. Although neoplasia is reported in nondomestic felids, only very few concern cheetahs. So far, no case of basal cell tumor was described in this species.
