    Full Text Available Basal cell carcinoma (BCC remains the most common form of nonmelanoma 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.

    Full Text Available Basal cell carcinoma originates from pluripotent cells of basal layer of epiderm, external covering of hair follicles, sebaceous glands or other skin adnexa. It is characterized by local infiltrating and sometimes destructive growth. There are several types of basal cell carcinomas that may be manifested in over 12 clinical forms. Surgical treatment depends to a large extent on the histological type, localization and its clinical manifestation. The analysis included 250 patients of both gender and different age, operated for basal cell carcinoma. Clinical characteristics of basal cell carcinoma and the width of the excision were described. It was concluded that the width of the excision of basal cell cancer was in relation to histological type. .

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

Here we show the discovery of four new BCC susceptibility loci: 2p24 MYCN (rs57244888[C], OR=0.76, P=4.7 × 10−12), 2q33 CASP8-ALS2CR12 (rs13014235[C], OR=1.15, P=1.5 × 10−9), 8q21 ZFHX4 (rs28727938[G], OR=0.70, P=3.5 × 10−12) and 10p14 GATA3 (rs73635312[A], OR=0.74, P=2.4 × 10−16). Fine mapping reveals that two variants correlated with rs73635312[A] occur in conserved binding sites for the GATA3 transcription factor. In addition, expression microarrays and RNA-seq show that rs13014235[C] and a related SNP rs700635[C] are associated with expression of CASP8 splice variants in which sequences from intron 8 are retained.

    Nevoid Basal Cell Carcinoma Syndrome (NBCCS) is an autosomal-dominant disorder characterized by multiple basal cell carcinomas, jaw cysts, palmar/plantar pits, calcification of the falx cerebri, and spine and rib anomalies. The combination of clinical, imaging, and histological findings is helpful in identifying NBCCS patients. Imaging plays a crucial role in evaluation of these patients. We present a wide variety of clinical and radiological findings characteristic of this disease. (orig.)

    Full Text Available O carcinoma basocelular é a neoplasia maligna mais comum em humanos e sua incidência vem aumentando nas últimas décadas. Sua grande frequência gera significativo ônus ao sistema de saúde, configurando problema de saúde pública. Apesar das baixas taxas de mortalidade e de rara ocorrência de metástases, o tumor pode apresentar comportamento invasivo local e recidivas após o tratamento, provocando importante morbidade. Exposição à radiação ultravioleta representa o principal fator de risco ambiental associado a sua gênese. Entretanto, descrevem-se outros elementos de risco: fotótipos claros, idade avançada, história familiar de carcinomas de pele, olhos e cabelos claros, sardas na infância e imunossupressão, além de aspectos comportamentais, como exercício profissional exposto ao sol, atividade rural e queimaduras solares na juventude. Entre 30% e 75% dos casos esporádicos estão associados à mutação do gene patched hedgehog, mas outras alterações genéticas são ainda descritas. A neoplasia é comumente encontrada concomitantemente com lesões cutâneas relacionadas à exposição solar crônica, tais como: queratoses actínicas, lentigos solares e telangiectasias faciais. A prevenção do carcinoma basocelular se baseia no conhecimento de fatores de risco, no diagnóstico e tratamento precoces e na adoção de medidas específicas, principalmente, nas populações susceptíveis. Os autores apresentam uma revisão da epidemiologia do carcinoma basocelular.Basal cell carcinoma is the most common malignant neoplasm in humans and its incidence has increased over the last decades. Its high frequency significantly burdens the health system, making the disease a public health issue. Despite the low mortality rates and the rare occurrence of metastases, the tumor may be locally invasive and relapse after treatment, causing significant morbidity.

    Full Text Available Basal cell carcinoma is the most common malignant skin tumour. Chronic sun exposure is considered as the main etiologic factor in its development. Although it mainly occurs on sun-exposed areas as the face and neck, it rarely develops on the forearms and/or arms. The etiologic factors which affect the anatomic distribution of basal cell carcinoma are not well-known. Here we report two patients who developed basal cell carcinoma on the forearm. None of the patients had a specific etiologic factor except for chronic sunlight exposure. The aim of our report is to show that this prevalant cutaneous malignancy can be encountered in rare/unusual areas. (Turk J Dermatol 2012; 6: 51-4

    2012-01-01

    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.

    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.

    Prostatic basal cell proliferations range from ordinary basal cell hyperplasia (BCH) to florid basal cell hyperplasia to basal cell carcinoma. The distinction between these forms of BCH, including the variant with prominent nucleoli (formerly called atypical BCH), and basal cell carcinoma depends on morphological and immunohistochemical criteria and, in particular, on the degree of cell proliferation. In florid BCH, the proliferation index is intermediate between ordinary BCH and basal cell c...

The type of tumor in basal cell carcinoma and tumor differentiation in squamous cell carcinoma were noted and the paraffin block that best represented the tumor was chosen. Immunostaining by p53 and COX-2 was performed on sections of the paraffin blocks.Results: p53 expression was observed in 98% of basal cell carcinoma, 88.9% of squamous cell carcinoma and all actinic keratosis cases. p53 expression was also noted in non-dysplastic appearing epithelium in actinic keratosis cases. COX-2 expression was seen in 90, 100 and 88.9% of the basal cell carcinoma, squamous cell carcinoma and actinic keratosis groups, respectively. Skin appendages, inflammatory cells and vascular structures were also stained by COX-2 besides tumor tissue. COX-2 expression increased by the p53 expression increase in basal cell carcinoma and squamous cell carcinoma. p53 and COX-2 expressions were not related in terms of tumor type in the BCC and were not related in terms of differentiation in SCC.Conclusion: The existence of p53 expression in actinic keratosis cases has supported the idea that p53 plays a role in the early steps of carcinogenesis in skin cancers. The fact that the expression of COX-2 increases in line with the increase of p53 expression in basal cell carcinoma and squamous cell carcinoma cases indicates that COX-2 expression may be affected by p53

    Lyubomir A Dourmishev

    2013-01-01

    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.

  11. Novel Hedgehog pathway targets against basal cell carcinoma

    International Nuclear Information System (INIS)

    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 Background. Darier's disease (DD, also known as Keratosis Follicularis or Darier-White disease, is a rare disorder of keratinization. DD can present as a generalized autosomal dominant condition as well as a localized or segmental postzygotic condition (Vázquez et al., 2002. Clinical features of DD include greasy, warty papules and plaques on seborrheic 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 Darier's disease with only 8 previous cases reported to date. In addition, nonmelanoma skin cancer (NMSC arising from DD is rarely reported; however, there may be an association between DD and risk of carcinogenesis.

SNP rs11170164, encoding a G138E substitution in the keratin 5 (KRT5) gene, affects risk of BCC (OR = 1.35, P = 2.1 x 10(-9)). A variant at 9p21 near CDKN2A and CDKN2B also confers susceptibility to BCC (rs2151280[C]; OR = 1.19, P = 6.9 x 10(-9)), as does rs157935[T] at 7q32 near the imprinted gene KLF14 (OR = 1.23, P = 5.7 x 10(-10)). The effect of rs157935[T] is dependent on the parental origin of the risk allele. None of these variants were found to be associated with melanoma or fair-pigmentation traits. A melanoma- and pigmentation-associated variant in the SLC45A2 gene, L374F, is associated with risk of both BCC and squamous cell carcinoma. Finally, we report conclusive evidence that rs401681[C] in the TERT-CLPTM1L locus confers susceptibility to BCC but protects against melanoma. PMID:19578363

    Full Text Available Normal 0 false false false EN-US X-NONE X-NONE MicrosoftInternetExplorer4 Merkel cell carcinoma (MCC or primary cutaneous neuroendocrine carcinoma is a malignant tumor considered to demonstrate differentiation towards Merkel cells that are present at the base of the epidermis or around the apical end of some hair follicles and are thought to play an yet uncertain role in sensory transduction. Here we present the case of a 54-year-old female with a basal cell carcinoma (BCC of the skin with neuroendocrine features (positivity for chromogranin that has evolved during multiple recurrences and radiotherapy into a high-grade neuroendocrine carcinoma with morphologic and immunohistochemical features of MCC (trabecular and nesting arrangement, positivity for chromogranin, cytokeratin 20, neuron specific enolase, and also neurosecretory granules on electron microscopy. The progression from a chromogranin positive basal cell carcinoma of the skin, to a high grade neuroendocrine carcinoma demonstrates the potential for cross differentiation among skin tumors.

    We investigated human cutaneous basal cell carcinoma ex-vivo samples by combined time resolved two photon intrinsic fluorescence and second harmonic generation microscopy. Morphological and spectroscopic differences were found between malignant skin and corresponding healthy skin tissues. In comparison with normal healthy skin, cancer tissue showed a different morphology and a mean fluorescence lifetime distribution slightly shifted towards higher values. Topical application of delta-aminolevulinic acid to the lesion four hours before excision resulted in an enhancement of the fluorescence signal arising from malignant tissue, due to the accumulation of protoporphyrines inside tumor cells. Contrast enhancement was prevalent at tumor borders by both two photon fluorescence microscopy and fluorescence lifetime imaging. Fluorescence-based images showed a good correlation with conventional histopathological analysis, thereby supporting the diagnostic accuracy of this novel method. Combined morphological and lifetime analysis in the study of ex-vivo skin samples discriminated benign from malignant tissues, thus offering a reliable, non-invasive tool for the in-vivo analysis of inflammatory and neoplastic skin lesions.

  1. Perineural Infiltration of Cutaneous Squamous Cell Carcinoma and Basal Cell Carcinoma Without Clinical Features

    International Nuclear Information System (INIS)

    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.

  3. Neglected Basal Cell Carcinomas in the 21st Century

    Full Text Available 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.

  4. Ionizing Radiation Exposure and Basal Cell Carcinoma Pathogenesis.

    2016-03-01

    This commentary summarizes studies showing risk of basal cell carcinoma (BCC) development in relationship to environmental, occupational and therapeutic exposure to ionizing radiation (IR). BCC, the most common type of human cancer, is driven by the aberrant activation of hedgehog (Hh) signaling. Ptch, a tumor suppressor gene of Hh signaling pathway, and Smoothened play a key role in the development of radiation-induced BCCs in animal models. Epidemiological studies provide evidence that humans exposed to radiation as observed among the long-term, large scale cohorts of atomic bomb survivors, bone marrow transplant recipients, patients with tinea capitis and radiologic workers enhances risk of BCCs. Overall, this risk is higher in Caucasians than other races. People who were exposed early in life develop more BCCs. The enhanced IR correlation with BCC and not other common cutaneous malignancies is intriguing. The mechanism underlying these observations remains undefined. Understanding interactions between radiation-induced signaling pathways and those which drive BCC development may be important in unraveling the mechanism associated with this enhanced risk. Recent studies showed that Vismodegib, a Smoothened inhibitor, is effective in treating radiation-induced BCCs in humans, suggesting that common strategies are required for the intervention of BCCs development irrespective of their etiology.

    Background and Objectives. Laser-induced autofluorescence (LIAF) is a promising tool for cancer diagnosis. This method is based on the differences in autofluorescence spectra between normal and cancerous tissues, but the underlined mechanisms are not well understood. The objective of this research is to study the microscopic origins and intrinsic fluorescence properties of basal cell carcinoma (BCC) for better understanding of the mechanism of in vivo fluorescence detection and margin delineation of BCCs on skin patients. A home-made micro- spectrophotometer (MSP) system was used to image the fluorophore distribution and to measure the fluorescence spectra of various microscopic structures and regions on frozen tissue sections. Materials and Methods. BCC tissue samples were obtained from 14 patients undergoing surgical resections. After surgical removal, each tissue sample was immediately embedded in OCT medium and snap-frozen in liquid nitrogen. The frozen tissue block was then cut into 16-μm thickness sections using a cryostat microtome and placed on microscopic glass slides. The sections for fluorescence study were kept unstained and unfixed, and then analyzed by the MSP system. The adjacent tissue sections were H&E stained for histopathological examination and also served to help identify various microstructures on the adjacent unstained sections. The MSP system has all the functions of a conventional microscope, plus the ability of performing spectral analysis on selected micro-areas of a microscopic sample. For tissue fluorescence analysis, 442nm He-Cd laser light is used to illuminate and excite the unstained tissue sections. A 473-nm long pass filter was inserted behind the microscope objective to block the transmitted laser light while passing longer wavelength fluorescence signal. The fluorescence image of the sample can be viewed through the eyepieces and also recorded by a CCD camera. An optical fiber is mounted onto the image plane of the photograph

    2006-05-01

    Full Text Available Basal cell and squamous cell carcinoma of skin are common tumors which can be easily distinguished on hematoxylin and eosin stained sections, but basosquamous carcinoma is a controversial entity. The aim of our study was to distinguish basal cell carcinoma and basosquamous carcinoma using Ber-EP4, immunohistochemically in 52 skin tumors. Twenty basal cell carcinomas, 20 squamous cell carcinomas, 10 basosquamous carcinomas and 2 collision tumors of the skin were stained with Ber-EP4 immunohistochemically. All basal cell carcinomas were stained strongly and diffusely with Ber-EP4, whereas squamous cell carcinomas were not, and basosquamous carcinomas were partially stained. Our results suggest that, distinction of basal cell carcinoma and basosquamous carcinoma can be achieved with routine immunohistochemical Ber-EP4 staining.

    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.

    Long noncoding RNAs (lncRNAs) are fundamental regulators of pre- and post-transcriptional gene regulation. Over 35,000 different lncRNAs have been described with some of them being involved in cancer formation. The present study was initiated to describe differentially expressed lncRNAs in basal cell carcinoma (BCC). Patients with BCC (n = 6) were included in this study. Punch biopsies were harvested from the tumor center and nonlesional epidermal skin (NLES, control, n = 6). Microarray-based lncRNA and mRNA expression profiles were identified through screening for 30,586 lncRNAs and 26,109 protein-coding transcripts (mRNAs). The microarray data were validated by RT-PCR in a second set of BCC versus control samples. Gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses of mRNAs were performed to assess biologically relevant pathways. A total of 1851 lncRNAs were identified as being significantly up-regulated, whereas 2165 lncRNAs were identified as being significantly down-regulated compared to nonlesional skin (p < 0.05). Oncogenic and/or epidermis-specific lncRNAs, such as CASC15 or ANRIL, were among the differentially expressed sequences. GO analysis showed that the highest enriched GO targeted by up-regulated transcripts was "extracellular matrix." KEGG pathway analysis showed the highest enrichment scores in "Focal adhesion." BCC showed a significantly altered lncRNA and mRNA expression profile. Dysregulation of previously described lncRNAs may play a role in the molecular pathogenesis of BCC and should be subject of further analysis. PMID:26861560

  10. Panoramic zonography in evaluation of recurrent basal cell carcinoma of the face

    International Nuclear Information System (INIS)

    Nine patients with recurrent, facial basal cell carcinoma were followed up both clinically and radiographically using a panoramic technique. A cylindrical image track was used for panoramic radiography. Five patients had bony destruction due to tumour re-occurence, four patients had bony defects caused by surgery. The confirmation of the results by surgery and/or follow-up shows that the spread of basal cell carcinoma into bone can be diagnosed using a panoramic technique. (orig.)

    @@ Basal cell carcinoma (BCC) is the most common cancer of the skin. However, BCC occurring on non-sun-exposed sites, especially the genital regions such as scrotum and labia, are very rare. An estimated annual incidence of basal cell carcinoma of the scrotum is 1 per 1 000 000 population.1 Here, we report a man with scrotal BCC with the lesion for 51 years, the longest one in the documents. He was successfully treated by circumferential excision.

  14. A subset of prostatic basal cell carcinomas harbor the MYB rearrangement of adenoid cystic carcinoma.

    Adenoid cystic carcinoma (ACC) is a basaloid tumor consisting of myoepithelial and ductal cells typically arranged in a cribriform pattern. Adenoid cystic carcinoma is generally regarded as a form of salivary gland carcinoma, but it can arise from sites unassociated with salivary tissue. A rare form of prostate carcinoma exhibits ACC-like features; it is no longer regarded as a true ACC but rather as prostatic basal cell carcinoma (PBCC) and within the spectrum of basaloid prostatic proliferations. True ACCs often harbor MYB translocations resulting in the MYB-NFIB fusion protein. MYB analysis could clarify the true nature of prostatic carcinomas that exhibit ACC features and thus help refine the classification of prostatic basaloid proliferations. Twelve PBCCs were identified from the pathology consultation files of Johns Hopkins Hospital. The histopathologic features were reviewed, and break-apart fluorescence in situ hybridization for MYB was performed. All 12 cases exhibited prominent basaloid histology. Four were purely solid, 7 exhibited a cribriform pattern reminiscent of salivary ACC, and 1 had a mixed pattern. The MYB rearrangement was detected in 2 (29%) of 7 ACC-like carcinomas but in none (0%) of the 5 PBCCs with a prominent solid pattern. True ACCs can arise in the prostate as is evidenced by the presence of the characteristic MYB rearrangement. When dealing with malignant basaloid proliferations in the prostate, recommendations to consolidate ACCs with other tumor types may need to be reassessed, particularly in light of the rapidly advancing field of biologic therapy where the identification of tumor-specific genetic alterations presents novel therapeutic targets.

    Basal cell carcinoma is the most common malignant tumor of the skin, and it develops most frequently on the areas of the body that make its treatment and care extremely difficult, especially in cases of neglecting or aggressive growth and invasion. Both typical mild cases as well as locally aggressive tumor types do not tend to metastasize, and it has been postulated that they should share some common biological and morphological features that might explain this behavior. In this study, we have utilized a high-resolution three-dimensional reconstruction technique on pathological samples from 15 cases of common aggressive (fibrosing and adenoid types) and mild (superficial type) basal cell carcinomas, and showed that all these types shared contact points and bridges with the underlying basal cell layer of the epidermis or with the outmost layer of the hair follicle. The connections found had in fact the highest number for fibrosing type (100%), compared to the superficial (85.71%) and adenoid (55%) types. The morphology of the connection bridges was also different, adjacent moderate to abundant inflammatory infiltrate seeming to lead to a loss of basaloid features in these areas. For the adenoid type, tumor islands seemed to be connected also to each other more strongly, forming a common "tumor lace", and while it has been showed that superficial and fibrosing types have higher recurrence risks, all together these data might iterate a connection between the number of bridging points and the biological and clinical manifestation of this skin tumor.

    Animal experiments have demonstrated the photocarcinogenic properties of furocoumarins, a group of naturally occurring chemicals that are rich in citrus products. We conducted a prospective study for citrus consumption and risk of basal cell carcinoma (BCC) and squamous cell carcinoma (SCC) of the skin based on data from 41530 men in the Health Professionals Follow-up Study (1986-2010) and 63759 women in the Nurses' Health Study (1984-2010) who were free of cancers at baseline. Over 24-26 years of follow-up, we documented 20840 incident BCCs and 3544 incident SCCs. Compared to those who consumed citrus products less than twice per week, the pooled multivariable-adjusted hazard ratios were 1.03 [95% confidence interval (95% CI): 0.99-1.08] for BCC and 1.14 (95% CI: 1.00-1.30) for SCC for those who consumed two to four times per week, 1.06 (95% CI: 1.01-1.11) for BCC and 1.15 (95% CI: 1.02-1.28) for SCC for five to six times per week, 1.11 (95% CI: 1.06-1.16) for BCC and 1.22 (95% CI: 1.08-1.37) for SCC for once to 1.4 times per day and 1.16 (95% CI: 1.09-1.23) for BCC and 1.21 (95% Cl: 1.06-1.38) for SCC for 1.5 times per day or more (P trend = 0.001 for BCC and 0.04 for SCC). In contrast, consumption of non-citrus fruit and juice appeared to be inversely associated with risk of BCC and SCC. Our findings support positive associations between citrus consumption and risk of cutaneous BCC and SCC in two cohorts of men and women, and call for further investigations to better understand the potential photocarcinogenesis associated with dietary intakes.

    A 69-year-old white Italian woman was first seen at Memorial Sloan-Kettering Cancer Center in 1981 concerning several skin growths on her back. The patient had had several basal cell carcinomas surgically removed from her back during the preceding 5 years. There was no history of arsenic ingestion or prolonged sun exposure and her family history was negative for skin cancer. The patient had developed pulmonary tuberculosis in 1938 and was treated with pneumothorax therapy. She had had more than 50 fluoroscopic examinations of the chest following this therapy, as well as multiple diagnostic x-ray films since that time. On the back, clustered in the interscapular region, were multiple scars and nine erythematous nodules with pearly borders, telangiectasia, and translucent surfaces. Within several nodules there were areas of light and dark brown pigmentation. Biopsy of all lesions revealed basal cell carcinoma, some of which were pigmented, without evidence of chronic radiodermatitis. All lesions were treated with curettage and electrodesiccation three times with good cosmetic results

    The patient was a 76-year-old woman with multiple superficial basal cell carcinomas. She had undergone radiotherapy for a 1-year period after hysterectomy for uterine carcinoma 38 years previously, and the basal cell carcinomas coincided with the irradiated parts. No clear symptoms of chronic radioepithelitis could be found macroscopically, but the lesions were thought to represent radiation-induced carcinoma based on the histopathological findings (atrophy of the epidermis, hyalinization and sclerosis of dermal connective tissue, inflammatory cell infiltration, and capillary dilatation). The lesion was removed to the depth of the adipose tissue with a 5 mm margin around the tumor, and primary closure was achieved. No recurrences or new carcinomas have been detected during the 16 months since the operation. (K.H.)

Topical photodynamic therapy (PDT using aminolaevulinic acid or its methyl ester has recently become good treatment options for actinic keratosis and basal cell carcinoma; especielly when treating large areas and areas with field cancerization. The cure rates are usually good, and the cosmetic outcomes excellent. The only major side effect reported is the pain experienced by the patients during treatment. This review covers the fundamental aspects of topical PDT and its application for treatment of actinic keratosis and basal cell carcinoma. Both potentials and limitations will be reviewed, as well as some recent development within the field.Keywords: photodynamic therapy, actinic keratosis, basal cell carcinoma

    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.

  8. Patients' perceptions of their cosmetic appearance more than ten years after radiotherapy for basal cell carcinoma

    International Nuclear Information System (INIS)

    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)

    2013-01-01

    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.

    Full Text Available Basal cell carcinoma (BCC and squamous cell carcinoma are the most common type of nonmelanoma skin cancers (NMSCs. Bowen′s disease (BD, a premalignant condition, has a marginal potential (3-5% to progress to invasive carcinoma. We report here a rarest of a rare case of multiple pigmented BD with overlying squamous cell cancer along with a giant neglected BCC on the scalp of a 76-year-old man. The occurrence of multiple BD and NMSC in a single patient compelled us to explore the following hypothesis: (1 The multiple precancerous and cancerous lesions can be due to common etiopathogenesis. Chronic ultraviolet exposure, immunosupresssion, human papillomavirus infection, dietary factors, and environmental factors including arsenic exposure were probed in to. (2 There is evolution of precancerous lesions into a different type of cancers in different time frame. (3 The new cancerous lesions are subsequent cancers that developed after neglected untreated primary cancer.

    Basal cell carcinomas of the skin and subcutaneous tissue of the face can spread into to orbit directly through the anterior orbit. Nine patients with radiological evidence of orbital involvement by basal cell carcinoma were studied with computed tomography. None of the patients had any previous treatment of the tumor. Ulcerated lesion of the eyelid was the most common sign of the disease (67%) whereas the inferior eyelid was the most frequent site of origin of the neoplasm (44%). All carcinomas extended into the orbit through the anterior orbit, involving mainly the extraconal space (89%). The orbital regions most frequently involved were the anterior, medial and superior compartments. Orbital extension of these carcinomas can result in orbital exenteration. Computed tomography is a valuable method for evaluating tumoral extension into the orbit and should be done when there is clinical suspicion of orbital involvement. (author)

  8. Review of photodynamic therapy with 5-methyl aminolevulinate in actinic keratosis, epidermoid carcinoma and basal cell carcinoma

    International Nuclear Information System (INIS)

    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

    International Nuclear Information System (INIS)

    The coexistence of a basal cell carcinoma and a port-wine stain is a very rare condition that may be associated with previous treatments. We present a case of multiple basal cell carcinomas developing within the boundaries of a port-wine stain, which had been treated with a tholium X and argon laser. Our case suggests that port-wine stains which were previously treated with irradiation or argon laser should be examined carefully and regularly by both physician and patient, because they may hide basal cell carcinomas.

    The nevoid basal cell carcinoma syndrome (NBCCS) is an autosomal dominant disorder characterized by nevi, palmar and plantar pits, falx calcification, vertebrate anomalies and basal cell carcinomas. It is well known in NBCCS that {gamma}-irradiation to the skin induces basal cell carcinomas or causes an enlargement of the tumor size, although the details of the mechanism remain unknown. We have established lymphoblastoid cell lines from three NBCCS patients, and we present here the first evidence of abnormal cell cycle and apoptosis regulations. A novel mutation (single nucleotide deletion) in the coding region of the human patched gene, PTCH, was identified in two sibling patients, but no apparent abnormalities were detected in the gene of the remaining patient. Nevertheless, the three established cell lines showed similar features in the following analyses. Flow cytometric analyses revealed that the NBCCS-derived cells were accumulated in the G{sub 2}M phase after {gamma}-irradiation, whereas normal cells showed cell cycle arrest both in the G{sub 0}G{sub 1} and G{sub 2}M phases. The fraction of apoptotic cells after {gamma}-irradiation was smaller in the NBCCS cells. The level of p27 expression markedly decreased after {gamma}-irradiation in the NBCCS cells, although the effects of the irradiation on the expression profiles for p53, p21 and Rb did not differ in normal and NBCCS cells. These findings may provide a clue to the molecular mechanisms of tumorigenesis in NBCCS. (author)

    Jiménez-Hernández, Fabiola; Caballero-Centeno, Ana M; Barrera-Pérez, María; Ramos-Garibay, José A

    2016-01-01

    Giant basal cell carcinomas (GBCCs) are a strange and aggressive variety of basal cell carcinomas (BCCs); they are characterized by deep tissue invasion, rapid growth, high risk of metastasis, and a poor prognosis. GBCCs represent 0.4%-1% of all BCCs. The pathogenesis of GBCC is sometimes linked to a spontaneous mutation in the PTCH gene, mapped to the q22.33 locus of chromosome 9. The key factor in the development of GBCC, in at least 30% of the cases, is the delay in seeking medical attention (7.5 ± 3.1 years). This is associated to a poor socioeconomic level, deficient hygiene, mental illness, advanced age, and the fact that BCCs are painless lesions. The authors present a Mexican female with a 2-year ulcer diagnosed as a GBCC in the year 2000, its initial therapeutic approach, and her follow-up during the next 12 years. PMID:26332533

    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.

    Malignant skin tumors are known to develop in areas of chronic radiodermatitis. We experienced a patient with multiple basal cell carcinomas that developed about 50 years after irradiation. The patient was a 77-year-old man who underwent radiotherapy in his twenties for caries in the left shoulder joint. The dose given was unknown. Black skin tumor appeared initially about 10 years before the first consultation. The skin around the tumor began to erode about six months before presentation. Biopsy of the tumor was done at another institution and revealed basal cell carcinoma (BCC), so the patients was referred to our department. In addition to the BCC measuring 35 x 20 mm in the left shoulder, BCC measuring 17 x 20 mm and 15 x 15 mm were found on the chest and the left axilla, respectively. The lesions were excised with a margin of 5 mm from the radiodermatitis, and the resultant skin defects were covered with latissimus dorsi flaps. All three tumors were basal cell carcinomas. The patients died of an unrelated disease six years after surgery and there was no recurrence of his tumors. (author)

  10. A case of microcystic adnexal carcinoma with multiple basal cell carcinoma and sebaceous carcinoma complicated radiation dermatitis

    International Nuclear Information System (INIS)

    A 65-year-old Japanese man presented with an asymptomatic nodule of 3-month history on the right side of the nose. He had received radiation therapy for hemangioma of the nose when he was 17 years old. On physical examination, the nodule was dome shaped, dark-red colored and 15 mm in size. Multiple black nodules varying from 1 to 3 mm in size were also scattered on the poikilodermatous skin of his cheek and nose. In addition, an indurated plaque, 10 mm in size, was detected on the right nostril. Histopathologically, the nodule showed solid nests composed of atypical basaloid cells and foamy-vacuolated cells. The black nodules were revealed to be basal cell carcinoma. In the plaque lesion of the nostril, multiple discrete nests were found in the entire dermis and subcutis. The nests were partly continuous with the epidermal keratinocyte, and composed of atypical squamoid and basaloid cells with small keratinous cysts in the upper part. Interestingly, the neoplastic cells composing the discrete nests in the lower dermis showed vacuolated cytoplasm, indicating sebaceous differentiation. (author)

    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.

    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.

    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%.

    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

    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.

    The purpose of the present study was to assess the role of hedgehog signaling pathway in the carcinogenesis of eyelid skin and conjunctival epithelial malignant tumors. The study was conducted on specimens from 41 patients with cutaneous eyelid basal cell carcinoma, 22 with bulbar conjunctival squamous cell carcinoma, 12 with bulbar conjunctival intraepithelial neoplasia. Major molecules of Hedgehog signaling pathway (Sonic Hedgehog [Shh] and Patched-1 [Ptch-1] and Glioma-associated oncogene [Gli-1]) were evaluated in paraffin-embedded tissue specimens using immunohistochemical staining. For each specimen, the percentage (50%) and the intensity of the immunohistochemical staining (graded from 0 to 3) were calculated and the scores obtained by multiplication of two values were analyzed using the Kruskall-Wallis test. Shh and Ptch-1 expression levels were statistically significantly lower in the basal cell carcinoma group compared with the squamous cell carcinoma group (P=0.043 for Shh; P=0.030 for Ptch-1). In the conjunctival squamous cell carcinoma group, the Ptch-1 score was 0 in ~25% of specimens and the Gli-1 score was ≤2 in ~45% of cases. In the conjunctival intraepithelial neoplasia group, the Ptch-1 score was ≥2 in 66% of specimens, the Gli-1 score was ≤2 in ~92% of cases. Ptch-1 mutations contribute to the development of cutaneous eyelid basal cell carcinoma. The present study provides evidence that alterations in hedgehog signaling pathways may lead to transformation of the conjunctival intraepithelial neoplasia into invasive squamous cell carcinoma.

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.

    Chronic lymphedema presents as interstitial fluid retention due to a failure in the lymphatic system drainage. The affected region becomes more vulnerable immunologically and predisposed to the onset of neoplasms. Basal Cell Carcinoma is the most common sort of neoplasm, nevertheless it rarely metastisizes. Sarcomas are malignant mesenchymal neoplasms, locally aggressive, which can spread. Here is reported an infrequent case of multiple basal cell carcinoma, synchronous to a poorly differentiated pleomorphic sarcoma, both spreading to lymph nodes and arising from tissue compromised by chronic lymphedema.

  14. Basal cell carcinoma of the scalp after radiation therapy for tinea capitis: 33 patients

    International Nuclear Information System (INIS)

    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.

    Syringoid carcinoma (syringoid eccrine carcinoma, or eccrine epithelioma) is a rare cutaneous tumor with some controversy regarding its correct definition. This tumor shows a slow growth and has often been for many years, some decades before diagnosis. It may also be difficult to differentiate from its benign counterpart (syringoma) or other adnexal carcinoma and cutaneous metastasis. There have been limited case reports of syringoid carcinoma in foreign literatures but none from Iran. Here we report a case of syringoid carcinoma in a 52 year-old Iranian man. Syringoid eccrine carcinoma is a very rare and uncommon diagnosed tumor thought to be derived from eccrine sweat apparatus. It locally invasive, destructive and often shows recurrence. It may also be difficult to differentiate from metastatic adenocarcinoma.

    Xeroderma pigmentosum (XP) is an autosomal recessive disease characterized by solar sensitivity, photophobia, early onset of freckling, and solar-induced cutaneous neoplastic changes. Management of patients with XP is a therapeutic challenge as they usually develop multiple cutaneous malignancies, making surgical therapy difficult, and continue to form skin malignancies at a high rate. We describe a 30-year-old Chinese man with XP who had been previously treated with excision and dermatoplasty. Upon recurrence of multiple superficial, ulcerative, and pigmented lesions, imiquimod 5% cream was recommended for 4 months. His multiple facial lesions demonstrated an excellent response to topical imiquimod 5% cream with minor side effects. This favorable response indicates that topical application of imiquimod 5% cream is an effective means of treating multiple basal cell carcinomas in XP. PMID:25754701

    To search for new sequence variants that confer risk of cutaneous basal cell carcinoma (BCC), we conducted a genome-wide association study of 38.5 million single nucleotide polymorphisms (SNPs) and small indels identified through whole-genome sequencing of 2230 Icelanders. We imputed genotypes for 4208 BCC patients and 109 408 controls using Illumina SNP chip typing data, carried out association tests and replicated the findings in independent population samples. We found new BCC susceptibility loci at TGM3 (rs214782[G], P = 5.5 × 10−17, OR = 1.29) and RGS22 (rs7006527[C], P = 8.7 × 10−13, OR = 0.77). TGM3 encodes transglutaminase type 3, which plays a key role in production of the cornified envelope during epidermal differentiation. PMID:24403052

    Basal cell carcinomas (BCCs) are one of the most frequent cutaneous malignancies. The majority of BCCs are reported to occur on the auricular helix and periauricular region due to ultraviolet light exposure. Despite the frequency of BCCs, those that develop within scar tissue are rare, and the phenomenon of keloid BCCs has rarely been reported in the literature. Keloid collagen within BCCs is associated with morphoeiform characteristics, ulceration, or necrosis. Extensive keloid collagen is often seen in BCCs of the ear region, a site prone to keloid scarring. This article presents a rare case of a secondary tumor (BCC) which arose on top of a primary tumor (keloid scar) on the right auricle region in a healthy 23-year-old female after an ear piercing 2 years prior. To our knowledge, the tumor described in this case, in contrast to keloidal BCCs, has never been reported in the literature. PMID:27536142

    Full Text Available 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 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.

    Basal cell carcinoma (BCC) is the most common cancer worldwide with an annual incidence of 2.8 million cases in the United States alone. Previous studies have demonstrated an association between 21 distinct genetic loci and BCC risk. Here, we report the results of a two-stage genome-wide association study of BCC, totalling 17,187 cases and 287,054 controls. We confirm 17 previously reported loci and identify 14 new susceptibility loci reaching genome-wide significance (P<5 × 10(-8), logistic regression). These newly associated SNPs lie within predicted keratinocyte regulatory elements and in expression quantitative trait loci; furthermore, we identify candidate genes and non-coding RNAs involved in telomere maintenance, immune regulation and tumour progression, providing deeper insight into the pathogenesis of BCC.

    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.

    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.

    2016-01-01

    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.

    2013-01-01

    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.

    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.

  8. Basal Cell Carcinoma in Gorlin's Patients: a Matter of Fibroblasts-Led Protumoral Microenvironment?

    Directory of Open Access Journals (Sweden)

    Yannick Gache

    Full Text Available 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

  9. External beam radiotherapy for basal cell carcinoma. Local control and cosmetic outcome

    International Nuclear Information System (INIS)

    Background: The basal cell carcinoma which is often occurring in the elderly can be well treated by surgery. For large and recurrent lesions and in cosmetically difficult locations external beam radiotherapy provides an equally effective treatment alternative. Patients and Methods: From 1986 to 1999, 60 females and 39 males received primary radiotherapy for a total of 127 histologically verified basal cell carcinoma lesions. Tumors were mostly localized in the face at the temple, nose and forehead. Radiotherapy was applied with orthovoltage equipment and energies of up to 100 kV. Single doses ranged from 2 to 5 Gy related to the 80%-isodose depth. Weekly doses ranged from 8 to 25 Gy and total doses from 25 to 60 Gy. The mean follow-up period was 36±21 months. The acute sequelae were scored according to CTC criteria. Radiogenic late effects as single events were related to the radiation portal. Results: 3 months after treatment all besides one patient (99%) experienced complete tumor remission (CR). In all cases, acute radiation reaction occurred within the radiation portal: CTC Grade 1 in 100%, CTC Grade 2 in 54% and CTC Grade 3 in 30% of the cases. All side effects regressed under simple local measures without further complications. Late sequelae were observed in three cases. Overall cosmetic outcome was good to excellent in almost all patients (98%). In two cases (2%) a local recurrence was observed 6 and 20 months after radiotherapy. Conclusion: External beam (orthovoltage) radiotherapy is very effective and yields high tumor control rates and good cosmetic results in long-term follow-up. Former dermatological treatment concepts should be replaced by an ICRU-based radiophysical dose prescription and should respect the newer radiobiological fractionation principles. (orig.)

    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.

  12. Metastasis of basal cell carcinoma to lymph nodes in a patient with Gorlin syndrome - case report and literature review

    International Nuclear Information System (INIS)

    Background: Basal cell carcinoma of the skin is the most common malignant cancer worldwide. It is characterized by a low grade of malignancy and it gives very rare metastases to lymph nodes or internal organs. It is also a typical symptom of Gorlin syndrome, which is characterized by multiple basal cell carcinomas, calcifications in the central nervous system and palmar or plantar pits. Mutations in the PTCH gene are responsible for the development of this syndrome, and its inheritance is autosomal dominant. The estimated frequency of Gorlin syndrome is 1/57 000 - 256 000. Case report: The authors present a case of a 34-year-old man with Gorlin syndrome and metastasis of basal cell carcinoma of the face to the submandibular lymph node. Though there are some reports of high radiosensitivity in patients with this syndrome, in this case postoperative radiation treatment was used. Inter- and post-treatment observation did not confirm an early or late postradiation reaction higher than score 2 on the EORTC/RTOG scale. Within 20 months after the treatment no new malignant lesions of the irradiated skin were noticed. Discussion: In the literature there are fewer than 300 cases of basal cell carcinoma metastases, of which only 3 concern patients with Gorlin syndrome. On the basis of the case presented the authors suggest that early and late radiation toxicity in Gorlin syndrome patients is not as high as previously believed. (authors)

    We describe a technique for monitoring excision margins in periocular basal cell carcinoma (BCC) using en face frozen sections and report outcomes. We excised periocular BCC with 3mm margins. An outer 1mm sliver of the perimeter of the specimen was mapped and sent for evaluation by en face frozen section. The central tumour mass was processed using routine paraffin sections. A further 3mm level was excised at the site of any affected margin and the outer 1mm sliver was again evaluated by frozen section. We identified 78 patients from November 2003 to July 2009; 67 had primary tumours and 11 (14%) had recurrent BCC of which 52 (66%) were located on the lower eyelid. Growth patterns were nodular (n=34, 43%), infiltrative (n=25, 32%), micronodular (n=12, 16%), and superficial (n=7, 9%). A third of BCC with a clinically nodular appearance showed additional histological patterns including infiltrative and micronodular growth patterns. Of 30 clinically nodular carcinomas, 29 were excised completely with one level, and one required 2 levels of excision for clearance after evaluation by frozen section. Mean follow-up was 23 months (range 2-60). There was one recurrence (1%). Excision of margins guided by en face frozen section is justified by the low rates of recurrence, and it can easily be taught or imported into hospital practice. Clinically nodular BCC have subclinical extensions that can be missed on bread loaf sectioning, which makes the sampling of margins a standard for periocular BCC. PMID:23219018

  14. Arecoline decreases interleukin-6 production and induces apoptosis and cell cycle arrest in human basal cell carcinoma cells

    International Nuclear Information System (INIS)

    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

    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

  16. Pattern of mRNA expression of β-defensins in basal cell carcinoma

    International Nuclear Information System (INIS)

    Although the human β-defensins hBDs today seem to have diverse functional activities in innate antimicrobial immunity, a few reports also indicated an altered expression of these antimicrobial peptides (AMPs) in tissues of cancers such as oral squamous cell carcinoma. The present work was aimed on the study of hBD gene expression in basal cell carcinoma (BCC) which is the most common cancer in humans. Twenty-two non-ulcerated BCCs (12 nodular type, 10 superficial type) have been analysed for the presence of hBD (1–3) mRNA by quantitative real-time RT-PCR. As controls, non-lesional skin specimens of BCC patients as well as samples of healthy subjects were assessed by RT-PCR. hBD-1 levels in healthy controls and non-lesional skin of BCC patients were significantly (P < 0.05) higher than the levels observed in tumour tissue. Moreover, BCCs showed significantly (P < 0.05) increased mRNA expression of hBD-2 as compared to controls. There was no significant (P > 0.05) difference between lesional mRNA levels for hBD-3 and those levels observed in controls. The mRNA expression of hBDs (1–3) found in nodular and superficial BCCs did not significantly (P > 0.05) differ. The gene expression patterns of hBD-1 and hBD-2 are for the first time shown to be significantly altered in non-ulcerated BCCs as compared to intra-individual and inter-individual controls, respectively. The present findings may indicate that beside the antimicrobial activity of AMPs, hBDs may also play a role in the pathogenesis of BCC. However, functional and immunohistological studies investigating hBDs in patients with BCC are needed to confirm our data

    Full Text Available Incidence of basal cell carcinoma (BCC, the most common skin cancer in humans, is rising. Surgery is the mainstay of treatment but there is no standard of care for locally advanced or metastatic disease. Hedgehog signaling proteins are critical for cell growth and differentiation during embryogenesis; Hh pathway is silenced in adults. Dysregulated or aberrant Hh signaling has been implicated in the pathogenesis of BCC. This hyperactive pathway can be inhibited by use of smoothened inhibitors such as vismodegib. Food and drug administration approved this oral, once-daily medication in 2012 to treat adults with metastatic BCC or locally advanced, recurrent BCC after surgery and also for patients with locally advanced BCC who are not candidates for surgery or radiation treatment. Clinical studies have shown it to be highly efficacious and the most common adverse effects include, muscle spasms, alopecia and dysgeusia. Use of targeted biologic modifiers, exemplified by Hh directed therapeutics offer a new hope to patients with high-surgical morbidity or inoperable tumors.

    Topical photodynamic therapy (PDT) is a promising alternative for malignant skin diseases such as basal-cell carcinoma (BCC), due to its simplicity, enhanced patient compliance, and localization of the residual photosensitivity to the site of application. However, insufficient photosensitizer penetration into the skin is the major issue of concern with topical PDT. Therefore, the aim of the present study was to enable penetration of photosensitizer to the different strata of the skin using a lipid nanocarrier system. We have attempted to develop a nanostructured lipid carrier (NLC) for the topical delivery of second-generation photosensitizer, 5-amino levulinic acid (5-ALA), whose hydrophilicity and charge characteristic limit its percutaneous absorption. The microemulsion technique was used for preparing 5-ALA-loaded NLC. The mean particle size, polydispersity index, and entrapment efficiency of the optimized NLC of 5-ALA were found to be 185.2 ± 1.20, 0.156 ± 0.02, and 76.8 ± 2.58%, respectively. The results of in vitro release and in vitro skin permeation studies showed controlled drug release and enhanced penetration into the skin, respectively. Confocal laser scanning microscopy and cell line studies respectively demonstrated that encapsulation of 5-ALA in NLC enhanced its ability to reach deeper skin layers and consequently, increased cytotoxicity.

    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.

  20. Usefulness of Photodynamic Therapy as a Possible Therapeutic Alternative in the Treatment of Basal Cell Carcinoma

    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.

  1. Basal and squamous cell carcinoma of the eyelids and their treatment by radiotherapy

    International Nuclear Information System (INIS)

    The authors report 1,166 tumors of the eyelids that were treated by single or fractionated exposures to doses of 20-60 Gy. The five year tumor control rate was 95% for basal cell and 93.3% for squamous cell carcinoma. Irradiation was equally successful in primary cases and in those recurrent following surgery. The cosmetic and functional results were generally excellent and readily accepted by most patients. The overall complication rate was 9.6% with fewer than one-half rated as serious; these problems mainly occurred with large tumors that had destroyed normal tissues. In only 14 (1.2%) patients was death related to the tumor. Approximately one-half of the patients received a dose of 35 Gy in five daily fractions, one-quarter, 20 to 22.5 Gy in a single exposure and the others with larger tumors 42.5-60 Gy in 10 to 30 exposures in two to six weeks

    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.

    Advanced basal cell carcinoma (aBCC) encompasses locally advanced BCC (laBCC) and metastatic BCC (mBCC), two variants of BCC with a limited prevalence worldwide. Treatment of aBCC is still very challenging for the lack of randomized controlled trials/guidelines and the scarcity of available therapeutic options. Based on current data, surgical procedures and radiotherapy are considered the treatments of choice for aBCC although often associated with substantial morbidity and/or deformity. Alternatively, systemic chemotherapy and electrochemotherapy can be used but standardized treatment schedules and randomized clinical trials are not available for both treatments. In recent years, novel tumor-specific and pathogenesis-based molecules have been developed for the treatment of aBCC. A number of clinical trials have recently demonstrated the efficacy and tolerability of vismodegib, the first novel systemic, anti-Smo target cancer therapy for aBCC. Additional molecules currently investigated in phase I-III clinical trials include other Smo antagonists and itraconazole. The contribution of a multidisciplinary team composed of dermatologists, surgeons, oncologists, pathologists, radiologists and radiotherapists is required to deal with the spectrum of issues that emerge from managing patients affected by aBCC.

    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.

    Traditionally, marking sutures have been used to orientate specimens of non-melanomatous skin cancers, and they provide an identifiable point as a reference for monitoring and further treatment. For histopathological purposes, the orientated specimen is marked with different inks, which enables measurement to the nearest lateral and deep margins, and if invaded, guides further excision. We retrospectively analysed 688 specimens of basal cell carcinoma (BCC) from the head and neck from two separate years: 2010 and 2012. Marking sutures were used in 663 (96%) cases. There were 21 invaded margins (3%), 17 (81%) at the lateral margin and 4 (19%) at the deep margin. Of the 17 with invaded lateral margins, 10 were from the nose, and the remaining 7 from other sites including the ear (n=2), and neck, forehead, temple, eyelid, and cheek (n=1 each). Of the 663 marked specimens, the marking stitch was useful in only one patient who needed another operation (0.2%). We suggest that routine orientation of BCC, even from high risk areas, is not necessary. If the operating surgeon questions the size of the margin when a lesion is ill-defined or of a high-risk histological subtype, then excision with monitored en-face margins should be considered with traditional Mohs surgery or a reliable modified version.

    Full Text Available Objective: The aim of this study was to verify the bcl-2 protein expression in 22 cutaneous basal cell carcinomas (BCC of the head and neck, and to compare it with its aggressive behavior. Method: Tumors were histologically classified in non-aggressive (BCC 1 and aggressive (BCC 2 and then submitted to the immunohistochemistry technique with the streptavidin-biotin peroxidase method using the anti-bcl-2 antibody. Results: After proceeding to morphological analysis, sixteen tumors (72.7% were considered aggressive and six (27.3% non-aggressive. Immunohistochemistry analysis showed that thirteen (59.1% lesions were positive staining and nine (40.9% were negative to the bcl-2 protein. Considering the positive lesions, 12 (92.3% were aggressive and one (7.7% non-aggressive. The relation between bcl-2 protein staining and the tumor aggressiveness was statistically significant (p<0.05 - Fisher's exact Test. Conclusion: The results suggest a relationship between the bcl-2 protein expression and the histological aggressiveness grade in the BCC of the head and neck group studied may exist.

    Treatment options for localized resectable basal cell carcinoma (BCC) include micrographically controlled surgery, simple excision, curettage, laser ablation, cryosurgery, imiquimod, 5-fluorouracil, photodynamic therapy and radiotherapy. The aim of this study was to assess the preferences of patients with BCC for outcome (cure and recurrence rate, cosmetic outcome, risk of temporary and permanent complications) and process attributes (type of therapy, treatment location, anaesthesia, method of wound closure, duration of wound healing, out-of-pocket costs) of these treatments with conjoint analysis. Participants (n = 124) attached greatest importance to recurrence rate (relative importance score (RIS) = 17.28), followed by cosmetic outcome (RIS = 16.90) and cure rate (RIS = 15.02). Participants with BCC on the head or neck were particularly interested in cosmetic outcome. Those with a recurrence were willing to trade risk of recurrence, treatment location and duration of wound healing for a better cosmetic result. In summary, participants particularly valued cure and cosmetic outcome, although preferences varied with individual and tumour-associated characteristics. PMID:26537095

    Full Text Available 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.

    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.

    Full Text Available Basal cell carcinomas (BCC on the genital area account for less than 1% of all BCCs. Surgical management is indicated. Recurrence rate of vulvar BCC has been reported to be 10-20%. Mohs micrographic surgery (MMS is a superior surgical option. Other treatments include radiation and topical immuntherapy. Cryosurgery for vulvar BCC has not been reported. We present the case of a 88-year-old Hispanic woman with a vulvar ulcer that was confirmed as BCC by histopathology and treated with liquid nitrogen cryosurgery. Control biopsy was performed on day 90 was negative for BCC. No clinical evidence of recurrence was detected after one year. Although, the vulva is considered to be a high-risk site with respect to BCC and MMS is the gold standard for treatment, the delicate nature of the area may preclude complete removal by a surgical technique without compromising vital anatomical function. Liquid nitrogen cryosurgery uses the effects of extreme cold to effect deep destruction of the tumor and surrounding tissues. This is the first report of a vulvar BCC successfully treated with liquid nitrogen cryosurgery. We suggest this technique could be of benefit as an alternative treatment in cases where excisional procedures cannot be performed.

    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.

    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.

  13. Immunohistochemical evaluation of E-cadherin expression in basal cell carcinoma of the skin

    Vladimír Bartoš

    2015-08-01

    Full Text Available Introduction: E-cadherin is important cell-cell adhesion molecule, that plays a crucial role in the maintenance of tissue microarchitecture. In many human malignancies, reduced or loss of E-cadherin production in neoplastic cells correlates with tumor dedifferentiation and acquisition of the invasive and metastatic potential. In contrast to most other cancers, basal cell carcinoma (BCC of the skin possess some unique features, such as slow local growth, strong stroma-dependency, and virtual absence of metastases. Aim: In the present study, we immunohistochemically evaluated expression of E-cadherin in a set of cutaneous BCCs. Material and methods: Study group consisted of 41 primary BCCs cathegorized into non-infiltrative subroup (superfical and nodular subtypes and infiltrative subroup (nodular-infiltrative and infiltrative subtypes. Results: E-cadherin was expressed in all tumor specimens with variable quantitative range and intensity. There were 19 cases (46.3 % with preserved and 22 cases (53.7 % with reduced E-cadherin expression. In superficial, nodular, nodular-infiltrative and infiltrative BCC subtypes, reduced E-cadherin immunoreactivity was found in 40 % (2/5, 56.2 % (9/16, 54.5 % (6/11 and 55.5 % (5/9, respectively. We did not confirm a significant correlation between expression of E-cadherin and both given, non-infiltrative and infiltrative BCC subgroup. None of the tumors examined showed apparent decreasing immunostaining intensity in tumor tissue with increasing depth of invasion. There were not convincing differences either between the central and peripheral parts of tumor mass, or in the vertical dimension. Conclusions: Reduction of E-cadherin expression per se does not seem to directly contribute to the acqusition of more aggressive phenotype in cutaneous BCC. This may represent another peculiarity, by which BCC differs from the most other epithelial malignancies and reflect a distinct tumor biology.

    2011-11-01

    Full Text Available Abstract Background The pathogenic role of beta-HPVs in non melanoma skin cancer (NMSC, is not still completely understood, and literature data indicate that they might be at least cofactors in the development of certain cutaneous squamous cell carcinomas. However, only few reports contain data on basal cell carcinoma (BCC. The HPVs interact with many cellular proteins altering their function or the expression levels, like the p16INK4a and Akt. Our study aimed to determine the presence of different beta -HPV types and the expression of p16INK4a and Akt in BCC, the commonest NMSC, in the normal appearing perilesional skin and in forehead swab of 37 immunocompetent patients. Methods The expression of p16INK4a and Akt, by immunohistochemistry, and the HPV DNA, by nested PCR, were investigated in each sample. Results No correspondence of HPV types between BCC and swab samples was found, whereas a correspondence between perilesional skin and BCC was ascertained in the 16,7% of the patients. In BCC, 16 different types of beta HPV were found and the most frequent types were HPV107 (15,4%, HPV100 (11,5% and HPV15 (11,5% all belonging to the beta HPV species 2. Immunohistochemistry detected significant p16INK4a expression in almost all tumor samples (94,3% with the highest percentages (> 30% of positive cells detected in 8 cases. A statistically significant (p = 0,012 increase of beta HPV presence was detected in p16INK4a strongly positive samples, in particular of species 2. pAkt expression was detected in all tumor samples with only 2 cases showing rare positive cells, whereas Akt2 expression was found in 14 out of 35 BCC (40%; in particular in HPV positive samples over-expressing p16INK4a. Conclusions Our data show that p16INK4a and pAkt are over-expressed in BCC and that the high expression of p16INK4a and of Akt2 isoform is often associated with the presence of beta-HPV species 2 (i.e. HPV 15. The association of these viruses with the up

    We have used ultra-low light level fluorescence microscopy to examine the suggestion that the relatively poor response of human basal cell carcinomas (BCC) to topical 5-aminolaevulinic acid (ALA)-based photodynamic therapy (PDT) arises from limited drug penetration into the lesion. The distribution of ALA-induced protoporphyrin IX (PpIX) in human BCC and Bowen's disease was examined and, in almost all cases, was found to be most intense in those regions of tumor immediately adjacent to the dermis. This distribution was independent of tumor type, and did not appear to be affected by tumor depth in the skin. It is suggested that ALA penetration may not limit the efficacy of ALA-PDT in the treatment of BCC. Failure of superficial ALA-based PDT in basal cell carcinoma may, instead, be related to the histological structure of this type of lesion.

    Full Text Available Cutis verticis gyrata is a rare disease characterized by convoluted folds and deep furrows of the scalp, resembling the gyri and sulci of the cerebral cortex. Basal cell carcinoma is the most frequent cancer in Caucasians, patients frequently presenting multiple tumors. We report the case of a 62 year old male, Caucasian patient, from the urban area, who addressed the dermatology department of our hospital for multiple tumors located on the face and upper trunk. A careful examination revealed cerebriform folding of the skin of the scalp. Neurological, psychological, ophthalmological and endocrine disorders were disproven. The patient was diagnosed with cutis verticis gyrata based on the clinical picture and anamnesis, and basal cell carcinoma based on the histopathological examination. Since cutis verticis gyrata predated the BCCs by four decades, and no other conditions were associated, the patient was diagnosed with primary essential cutis verticis gyrata.

    Background The large airways of the lungs (trachea and bronchi) are lined with a pseudostratified mucociliary epithelium, which is maintained by stem cells/progenitors within the basal cell compartment. Alterations in basal cell behavior can contribute to large airway diseases including squamous cell carcinomas (SQCCs). Basal cells have traditionally been thought of as a uniform population defined by basolateral position, cuboidal cell shape, and expression of pan-basal cell lineage markers l...

    Abnormal activation of hedgehog pathway signaling is a key driver in the pathogenesis of basal cell carcinoma (BCC). Vismodegib, a first-in-class small-molecule inhibitor of hedgehog pathway signaling, is approved by regulatory authorities for the treatment of adults who have metastatic BCC or locally advanced BCC that has recurred after surgery, or who are not candidates for surgery and who are not candidates for radiation. A second inhibitor, sonidegib, was also recently approved for the sa...

    Full Text Available PURPOSE: The objective of this study was to compare the estimated cost of clinical and surgical treatment for basl cell carcinoma of the eyelid. METHODS: This was a pilot study of 12 patients with basal cell carcinoma receiving treatment with 5% imiquimod cream at the ocular plastic surgery center, medical school University of São Paulo (HC-FMUSP, Brazil. The cost of clinical treatment was estimated based on the time of treatment and amount of medication consumed by patients in the home setting. The cost of surgical treatment was estimated by ophthalmologists with experience in reconstructive plastic surgery based on analysis of images of the same patients. Surgeons responded to a questionnaire with four questions about surgical technique, surgical materials required, estimated duration of surgery and type of anesthesia. RESULTS: Immunotherapy lasted from 8 to 12 weeks.All patients reported each coldstored sachet with 5% imiquimod cream lasted 3 days.According to the institution, a box with 12 sachets costs BRL 480.00. Patients required 1.58-3.11 boxes for complete treatment, corresponding to a total cost of BRL 758.401,492.80. Based on image analysis, surgeons evaluated surgery would require 1-3 hours. The estimated cost of surgery room and staff was BRL 263.00, to which the cost of supplies was added. Thus, the total cost of surgical treatment was BRL 272.61-864.82. On the average, immunotherapy was 57,64% more costly than surgical treatment. CONCLUSIONS: Malignant eyelid tumors are a common finding in clinical ophthalmology. Surgery is still the treatment of choice at our institution, but immunotherapy with 5% imiquimod cream may be indicated for patients with multiple lesions or high surgical risk and for patients declining surgery for reasons of fear or esthetic concerns.The ability to estimate costs related to the treatment of malignant eyelid tumors is an important aid in the financial planning of health care institutions.

    Full Text Available Background and Design: Basal cell carcinoma (BCC is the most frequently observed cancer. Its ethiopathogenesis is not totally clarified. In recent years one of the factors mentioned on ethiopathogenesis is ‘fusion regions’. In our study we aimed to investigate whether the number of BCC is more or not in anatomic areas which contain more fusion regions. Materials and Methods: Three hundred twenty-eight BCC case whose anatomic region is indicated in histopathology report is taken into study. Fusion regions are determined according to the mapping system given in Tessier’s publication. First the number of total fusion region for each anatomic area on face is calculated. Then, the number of BCC located in each anatomic area and the number of fusion region located in the same anatomic area are compared. In conclusion findings are commented with respect to cause result relationship. Results: The most important anatomic areas with respect to fusion region number were forehead and lip. In forehead and lip there were 11 fusion regions. 34 BCC on forehead and 14 BCC on lip are observed. There were 10 fusion regions on around the eye and a total of 74 BCC were observed on both periorbital area. But 9 fusion area is detected on nose area where BCC is mostly present (135. Conclusion: More BCC is not observed in anatomic areas where fusion region is plenty compared to anatomic areas where fusion region is less. As a result; in BCC development, it is seen that only fusion regions do not have ethiopathogenetic importance.

    Full Text Available Background/Aim. Basal cell carcinoma (BCC is the most common form of skin cancer in the white population. Increasing incidence of BCC imposes the requirement to identify the risk factors due to eventual preventive action. The aim of this study was to assess the role of some constitutional characteristics in development of BCC among the Montenegrin population. Methods. A case-control study was conducted at the Dermatology Department of Clinical Center of Montenegro in Podgorica from 2002−2003. The study group included 100 histopatologically confirmed BCC cases, while the control group consisted of 100 patients from the same department, who did not present skin cancer and who were individually matched to the cases by sex and age (±5 years. All participants were interviewed using an epidemiological questionnaire. For statistical analysis t test and McNemar χ2 test for matched pairs and multivariate logistic regression analyses were used. Results. The risk for development of BCC was increased among the persons with lighter hair color (t = 4.63; df = 99; p < 0.001, fair skin (t = 2.37; df = 99; p = 0.020, lighter eyes color (t = 2.86; df = 99; p = 0.005, with nevuses (OR = 13.13; p = 0.025; 95% IP = 1.39-12.03, and among those whose skin tone after sun exposure remained light (OR = 3.14; p = 0.001; 95%IP = 1.59-6.18. Conclusion. Our study confirmed the significance of constitutional characteristics such as lighter hair color, fair skin, lighter eyes color, and the presence of nevuses in the development of BCC. .

  4. Smoothened (SMO) receptor mutations dictate resistance to vismodegib in basal cell carcinoma.

    Basal cell carcinomas (BCCs) and a subset of medulloblastomas are characterized by loss-of-function mutations in the tumor suppressor gene, PTCH1. PTCH1 normally functions by repressing the activity of the Smoothened (SMO) receptor. Inactivating PTCH1 mutations result in constitutive Hedgehog pathway activity through uncontrolled SMO signaling. Targeting this pathway with vismodegib, a novel SMO inhibitor, results in impressive tumor regression in patients harboring genetic defects in this pathway. However, a secondary mutation in SMO has been reported in medulloblastoma patients following relapse on vismodegib to date. This mutation preserves pathway activity, but appears to confer resistance by interfering with drug binding. Here we report for the first time on the molecular mechanisms of resistance to vismodegib in two BCC cases. The first case, showing progression after 2 months of continuous vismodegib (primary resistance), exhibited the new SMO G497W mutation. The second case, showing a complete clinical response after 5 months of treatment and a subsequent progression after 11 months on vismodegib (secondary resistance), exhibited a PTCH1 nonsense mutation in both the pre- and the post-treatment specimens, and the SMO D473Y mutation in the post-treatment specimens only. In silico analysis demonstrated that SMO(G497W) undergoes a conformational rearrangement resulting in a partial obstruction of the protein drug entry site, whereas the SMO D473Y mutation induces a direct effect on the binding site geometry leading to a total disruption of a stabilizing hydrogen bond network. Thus, the G497W and D473Y SMO mutations may represent two different mechanisms leading to primary and secondary resistance to vismodegib, respectively. PMID:25306392

  5. 18-FDG PET/CT assessment of basal cell carcinoma with vismodegib

    International Nuclear Information System (INIS)

    The use of 18-fluorodeoxyglucose (FDG) positron emission tomography with computed tomography (PET/CT) in subjects with advanced basal cell carcinoma (BCC) has not been fully explored due to the rarity of disease presentation. This study evaluated PET/CTs from subjects with advanced BCC participating in a phase I dose-escalation clinical trial of vismodegib. Fourteen subjects with BCC were imaged with 18-FDG PET/CT for lesion identification and response categorizing (European Organisation for Research and Treatment for Cancer [EORTC] and PET response criteria in solid tumors [PERCIST] 1.0). Several parameters including metabolic activity of target lesions, site of disease presentation and spread, treatment response, and prognostic significance of metabolic activity following therapy were evaluated. All subjects exhibited at least one hypermetabolic lesion. Most subjects had only four organ systems involved at study enrollment: skin–muscle (93%), lung (57%), lymph nodes (29%), and bone (21%). SUVmax measured across all lesions decreased (median 33%, SD ± 45%) following therapy with metabolic activity normalizing or disappearing in 42% of lesions. No significant difference was observed between EORTC and PERCIST 1.0. Subjects that demonstrated at least a 33% reduction in SUVmax from baseline had a significantly longer progression-free survival (PFS) (median 17 months, 95% confidence interval [CI] ±4 months vs. 9 months, 95% CI ±5 months, P = 0.038) and overall survival (OS) (median 24 months, 95% CI ±4 months vs. 17 months, 95% CI ±13 months, P = 0.019). BCC lesions are hypermetabolic on 18-FDG PET/CT. A decrease in SUVmax was associated with improved PFS and OS. These results further support the incorporation of 18-FDG PET/CT scans in advanced BCC management

    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.

    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.

    Immune surveillance of skin cancer involves the stimulation of effector T cells by tumor-derived antigens and antigen-presenting cells (APCs). An effective APC must not only display processed antigen in the context of MHC molecules but also express co-stimulatory molecules that are required to fully activate T cells. One of the most common cutaneous neoplasms is basal cell carcinoma. To investigate expression of the co-stimulatory molecules CD80 (B7-1) and CD86 (B7-2) on tumor-associated dendritic cells (TADCs), cryosections from basal cell carcinomas were immunostained. In basal cell carcinomas, only 1 to 2% of intratumor and 5 to 10% of peritumor APCs expressed CD80 or CD86. In contrast, biopsies of immunological/inflammatory dermatoses revealed that 38 to 73% of APCs expressed CD80 and CD86. To further evaluate their phenotype and function, TADCs were isolated from tissue samples of basal cell carcinomas; they were non-adherent to plastic, displayed a typical dendritic morphology, and expressed high levels of major histocompatibility class II molecules on their surface. When TADCs were compared with dendritic cells from blood for presentation of superantigens (staphylococcal enterotoxins A and B) to resting autologous T cells, TADCs were consistently weaker stimulators of T cell proliferation than blood dendritic cells. When analyzed by flow cytometry, TADCs expressed high levels of HLA-DR, but only 5 to 10% co-expressed CD80 or CD86. A 3-day culture in granulocyte/macrophage colony-stimulating factor-containing medium partially reconstituted the TADC expression of CD80 and CD86 as well as their immunostimulatory capacity. Thus, in this common skin cancer, although there are prominent collections of HLA-DR-positive APCs in and around tumor cells, the TADCs are deficient in important co-stimulatory molecules as well as being weak stimulators of T cell proliferation. The paucity of co-stimulatory molecule expression and functional activity of TADCs may explain why

  17. Cultured diploid fibroblasts from patients with the nevoid basal cell carcinoma syndrome are hypersensitive to killing by ionizing radiation

    International Nuclear Information System (INIS)

    Nevoid basal cell carcinoma syndrome (NBCCS) is an autosomal dominant disease. About 20% of the gene carriers studied developed medulloblastoma before the age of 5 years. Clinical follow-up of these patients, treated with radiotherapy, revealed a predisposition to radiogenic basal cell carcinomas with an unusually short latent period of 6 months to 3 years. The authors have therefore cultured skin fibroblasts from 5 NBCCS patients and measured their radiosensitivity in terms of clonogenic survival. Our results showed that, compared with 6 normal controls, the NBCCS cells were hypersensitive to X-rays. The average D0 (the inverse of the slope of the survival curve) for the NBCCS cells was 98 rads, compared with 142 rads for the normal controls and 44 rads for an ataxia telangiectasia (AT) strain. The average D10 values (the dose required to reduce survival to 10%) were 258, 351, and 123 rads for the NBCCS, normal, and AT strains, respectively. Unscheduled DNA synthesis measurements showed that NBCCS cells were not defective in excision repair of X-ray-damaged DNA. Pulse labeling index measurements showed that NBCCS cells were abnormally inhibited in the initiation of DNA synthesis following X-irradiation. The mechanisms underlying the radiosensitivity of NBCCS differ in several respects from those of AT. NBCCS appears to be potentially a useful model for studying the cellular processes that are important in radiation carcinogenesis

    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

    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.

  2. Ultraviolet Radiation Exposure and Epidemiological Characteristics among Patients with skin Basal Cell Carcinoma in a National Dermatology Center in Colombia

    International Nuclear Information System (INIS)

    Objective: To describe patients with skin basal cell carcinoma attending a national dermatology center in Colombia, and explore history of exposure to ultraviolet radiation. Methods: A descriptive study was carried out among patients with histological diagnosis of skin basal cell carcinoma. Socio-demographic characteristics, and practices around exposure to ultraviolet radiation were analyzed through clinical examination and clinical history. Results: Average age was 65 years. More than 80% live in the Andean Region of the country. The higher percentage of ultraviolet radiation exposure occurred during school-age (76,4%), and simultaneously the lower rate of protective practices (hat: 8%; long sleeves: 9%; sun blocker: 0%). Countryside labor is the most common cause of labor exposure to ultraviolet radiation (ages under 15: 89%; ages over 30: 48%). In total 22% of cases corresponded to skin photo type III and 53% presented concomitant actinic keratosis. Conclusions: School-age children and countryside workers represent a priority for preventive campaigns, focusing educational activities mostly on schools. There is a need for evaluating risk factors, knowledge, and attitudes related to ultraviolet radiation among the Colombian population.

    The expression of c-erbB-1 and c-erbB-2 oncogenes were investigated by immunohistochemistry using monoclonal antibodies to c-erbB-1 and c-erbB-2 protein in 43 cases of basal cell carcinoma (BCC) and 26 cases of squamous cell carcinoma (SCC). We found that the expression of c-erbB-1 oncogene in all BCC increased by different degrees and the expression of c-erbB-2 oncogene in BCC was significantly reduced or lost when compared to that in normal epidermal cells.Furthermore,apparent negative and positive relationships were observed respectively between the tumor differentiation and the expression of c-erbB-1 and c-erbB-2 oncogenes in SCC.It is suggested that the abnormal expression of c-erbB-1 and c-erbB-2 oncogenes in BCC and SCC may play a role in the development of skin tumors.The pattern of the c-erbB-1 and c-erbB-2 oncogenes expression in SCC may assist in distinguishing the biological behavior and prognosis of SCC.

    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 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.

    We did a morphometric analysis of 130 histological sections of basal cell carcinoma (BCC) of the face to find out whether morphometric variables in the structure of the nuclei of BCC cells could serve as predictors of the biological behaviour. We considered the following variables: maximum and minimum diameters, perimeter, nuclear area and five form factors that characterise and quantify the shape of a structure (axis ratio, shape factor, nuclear contour index, nuclear roundness and circumference ratio). We did a statistical analysis of primary and recurring tumours and four histology-based groups (multifocal superficial BCCs, nodular BCCs, sclerosing BCCs and miscellaneous forms) using a two-sided t test for independent samples. Multifocal superficial BCCs showed significantly smaller values for the directly measured variables (maximum and minimum diameters, perimeter and nuclear area). Morphometry could not distinguish between primary and recurring tumours. PMID:12804537

    The object of this study was to investigate whether laser-induced skin autofluorescence (LIF) and/or light reflectance spectra could provide a useful contrast between basal cell carcinoma (BCC) tissues and the surrounding healthy skin. Unstained human skin samples, excised from humans undergoing biopsy examination, were irradiated with a nitrogen laser (lambda = 337 nm) for excitation of autofluorescence and a tungsten halogen lamp for the reflectance measurements. The ex vivo spectroscopic results were correlated with the histopathology images to distinguish the areas of BCC from those of the surrounding health skin. A simple spectral analysis technique was also applied for better skin diagnosis. In conclusion, it seems that LIF and reflectance spectra could be used to differentiate neoplastic from normal skin tissue using an appropriate classification model analysis. PMID:19365155

    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.

    2013-01-01

    Full Text Available The odontogenic keratocysts (OKC usually represent a particular entity that has been of interest mainly 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 mini review 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 perspective.

    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.

    2013-06-01

    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.

    Purpose Basal cell carcinoma (BCC) is a very common cancer in the Caucasian population. Treatment aims to eradicate the tumor with the lowest possible functional and aesthetic impact. Electronic brachytherapy (EBT) is a treatment technique currently emerging. This study aims to show the outcomes of two consecutive prospective pilot clinical trials using different radiation doses of EBT with Esteya® EB system for the treatment of superficial and nodular basal cell carcinoma. Material and methods Two prospective, single-center, non-randomized, pilot studies were conducted. Twenty patients were treated in each study with different doses. The first group (1) was treated with 36.6 Gy in 6 fractions of 6.1 Gy, and the second group (2) with 42 Gy in 6 fractions of 7 Gy. Cure rate, acute toxicity, and late toxicity related to cosmesis were analyzed in the two treatment groups. Results In group 1, a complete response in 90% of cases was observed at the first year of follow-up, whereas in group 2, the complete response was 95%. The differences with reference to acute toxicity and the cosmetic results between the two treatment groups were not statistically significant. Conclusions Our initial experience with Esteya® EB system to treat superficial and nodular BCC shows that a dose of 36.6 Gy and 42 Gy delivered in 6 fraction of 7 Gy achieves a 90% and 95% clinical cure rate at 1 year, respectively. Both groups had a tolerable toxicity and a very good cosmesis. The role of EBT in the treatment of BCC is still to be defined. It will probably become an established option for selected patients in the near future. PMID:26985197

    2015-11-01

    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.

    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.

    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.

    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.

    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.

    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.

    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.

  14. Constitutive NF-κB activity influences basal apoptosis and radiosensitivity of head-and-neck carcinoma cell lines

    International Nuclear Information System (INIS)

    Purpose: Nuclear factor-κB (NF-κB) has been implicated in anti-apoptotic gene transactivation, according to its transcriptional activity. The present study was designed to investigate whether constitutive NF-κB activity could modulate basal apoptosis and intrinsic radiosensitivity of KB head-and-neck carcinoma cell line and KB3 subline. The KB3 subline was more radiosensitive (SF2=0.48, α=0.064) than the radioresistant KB parental cell line (SF2=0.80, α=0.114). Methods and Materials: Constitutive NF-κB DNA-binding activity was determined using electrophoretic mobility shift assay. Modulation of NF-κB activity was performed by exposing both cell lines to tumor necrosis factor α or dexamethasone. Apoptotic cell population was analyzed using flow cytometry (annexin V/propidium iodide). Radiosensitivity was assessed from determination of the surviving fraction at 2 Gy (SF2), and α and β parameters were determined using the linear-quadratic model. Results: Constitutive NF-κB activity was found to be significantly lower in KB3 than in KB. KB cell line exposure to dexamethasone significantly decreased NF-κB DNA-binding activity and, consequently, enhanced baseline apoptosis and radiosensitivity (α values: 0.114 vs. 0.052). Conversely, exposure of KB3 cells to tumor necrosis factor α increased NF-κB DNA-binding activity and resulted in a significant decrease (50%) in rate of apoptosis and in radiosensitivity (SF2 values: 0.48 vs. 0.63). Conclusions: Modulation of NF-κB DNA-binding activity influences baseline apoptosis and intrinsic radiosensitivity

    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).

    Full Text Available Background. Photodynamic therapy (PDT has become a therapeutic option for basal cell carcinoma (BCC in the last decade. Objectives. To study the results and predictors of BCC response to treatment with PDT and to evaluate fluorescence diagnosis of BCC. Methods. A descriptive, retrospective, and observational study was carried out. Patients with biopsy-confirmed BCC who were treated with methyl aminolevulinate and red light according to standard treatment protocols (2 sessions separated by 2 weeks, 630 nm, 37 J/cm2, 8 minutes, Aktilite were selected. Response was scored as clinically complete and incomplete and the patients were followed up every three months. Results. Data from 191 BCC in 181 patients with a mean age of 69.55 years and a mean follow-up period of 34.4 months were collected. The overall response was 74% of the BCC treated, with the best response in superficial BCC with a 95% of complete response. The regression analysis revealed that the superficial histological type was the primary factor predictive of a complete response. Conclusions. In the treatment of BCC with PDT, the most significant factor for predicting response is the histological type.

    Full Text Available Background: Basal cell carcinoma (BCC is the most common type of skin cancer in humans. Photodynamic therapy (PDT is a non-invasive therapeutic modality that may be considered as a valuable treatment option for BCC. This study was designed with the aim of evaluating the efficacy of PDT in treatment of BCC and factors that may affect the response rate. Materials and Methods: This clinical trial was conducted on 12 patients (28 BCC lesions who were treated with aminulevulinic acid (ALA-PDT, monthly, up to 6 sessions and the clinical response, cosmetic results, and possible side effects were evaluated. Results: The study was performed on 28 BCC lesions from 12 patients. Complete response was achieved in 9 (32.1% lesions. Complete response rate was higher in younger patients ( P < 0.01 and those with smaller lesions ( P < 0.001. Superficial type also had significant higher response rate ( P < 0.05. Patients with history of radiotherapy for the treatment of tinea capitis in childhood showed less response ( P < 0.05. Cosmetic results were excellent or good in 77.5% cases. After 6 months of follow-up, none of the resolved lesions recurred. Conclusion: PDT would be a good therapeutic option in treatment of BCC with acceptable efficacy and low side effects. Younger patients, superficial BCCs, and smaller lesions show better response to ALA-PDT. History of radiotherapy may be associated with a lower response rate.

    Seven hundred sixty three basal cell carcinomas (BCCs) in 122 patients were treated by photodynamic therapy by 5-aminolevulinic acid (ALA) in cream topically applied, either alone, in combination with dimethyl sulphoxide (DMSO) and ethylenediaminetetraacetic acid disodium salt (EDTA), or with DMSO as a pretreatment. After 3 hours cream exposure 40 - 200 Joules/cm2 of 630 nm laser light was given. Fluorescence imaging of biopsies showed highly improved ALA penetration depth and doubled ALA-induced porphyrin production using DMSO/EDTA. Treatment response was recorded after 3 months. After a single treatment 90% of 393 superficial lesions responded completely, independent of using DMSO/EDTA. In 363 nodulo-ulcerative lesions the complete response rate increased from 67% to above 90% with DMSO/EDTA for lesions less than 2 mm thickness and from 34% to about 50% for lesions thicker than 2 mm. Recurrence rate observed during a follow-up period longer than 12 months was 2 - 5%. PDT of superficial thin BCCs with ALA-induced porphyrins and DMSO/EDTA equals surgery and radiotherapy with respect to cure rate and recurrence. Cosmetic results of ALA-based PDT seemed to be better than those after other therapies. In patients with the nevoid BCC syndrome the complete response rate after PDT was far lower.

    Aberrant activation of the Hedgehog (Hh) signaling pathway is implicated in the pathogenesis of many cancers, including medulloblastoma and basal cell carcinoma (BCC). In this study, using neonatally irradiated Ptch1(+/-) mice as a model of Hh-dependent tumors, we investigated the in vivo effects of MK-4101, a novel SMO antagonist, for the treatment of medulloblastoma and BCC. Results clearly demonstrated a robust antitumor activity of MK-4101, achieved through the inhibition of proliferation and induction of extensive apoptosis in tumor cells. Of note, beside antitumor activity on transplanted tumors, MK-4101 was highly efficacious against primary medulloblastoma and BCC developing in the cerebellum and skin of Ptch1(+/-) mice. By identifying the changes induced by MK-4101 in gene expression profiles in tumors, we also elucidated the mechanism of action of this novel, orally administrable compound. MK-4101 targets the Hh pathway in tumor cells, showing the maximum inhibitory effect on Gli1 MK-4101 also induced deregulation of cell cycle and block of DNA replication in tumors. Members of the IGF and Wnt signaling pathways were among the most highly deregulated genes by MK-4101, suggesting that the interplay among Hh, IGF, and Wnt is crucial in Hh-dependent tumorigenesis. Altogether, the results of this preclinical study support a therapeutic opportunity for MK-4101 in the treatment of Hh-driven cancers, also providing useful information for combination therapy with drugs targeting pathways cooperating with Hh oncogenic activity.

    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.

Células de Langerhans participam ativamente do sistema imune da pele. OBJETIVO - Avaliar quantitativamente as células de Langerhans sobrepostas aos carcinomas basocelulares de maior e menor potencial de agressividade local, assim como nas respectivas epidermes sãs adjacentes. MÉTODOS - Dois grupos com 14 preparações histológicas cada. No primeiro, carcinoma basocelular de menor potencial de agressividade local e, no segundo, carcinoma basocelular de maior potencial. Empregou-se a imunoistoquímica com proteína S100 para identificação das células de Langerhans. Utilizando microscópio óptico em aumento de 400 vezes e a grade morfométrica de Weibel, foram contadas as células de Langerhans presentes em sete campos, obtendo-se a média em cada lâmina. Foi utilizado teste estatístico de Wilcoxon para análise estatística. RESULTADOS - No grupo de menor potencial de agressividade local, na epiderme sã adjacente houve aumento significativo no número de células de Langerhans comparado ao da epiderme sobreposta ao carcinoma basocelular (p d 0,05. No grupo de maior potencial de agressividade local, não houve diferença com significado estatístico (p > 0,05. CONCLUSÃO - O maior número de células de Langerhans na epiderme sã vizinha à lesão tumoral de menor potencial de agressividade local poderia representar uma maior resistência imunológica da epiderme, limitando a agressividade da neoplasia.BACKGROUNDS - Basal cell carcinoma affects areas of the body that have been exposed to the sun, and this disorder has different clinical and histopathologic presentations.

    Background: The basal cell carcinoma which is often occurring in the elderly can be well treated by surgery. For large and recurrent lesions and in cosmetically difficult locations external beam radiotherapy provides an equally effective treatment alternative. Patients and Methods: From 1986 to 1999, 60 females and 39 males received primary radiotherapy for a total of 127 histologically verified basal cell carcinoma lesions. Tumors were mostly localized in the face at the temple, nose and forehead. Radiotherapy was applied with orthovoltage equipment and energies of up to 100 kV. Single doses ranged from 2 to 5 Gy related to the 80%-isodose depth. Weekly doses ranged from 8 to 25 Gy and total doses from 25 to 60 Gy. The mean follow-up period was 36{+-}21 months. The acute sequelae were scored according to CTC criteria. Radiogenic late effects as single events were related to the radiation portal. Results: 3 months after treatment all besides one patient (99%) experienced complete tumor remission (CR). In all cases, acute radiation reaction occurred within the radiation portal: CTC Grade 1 in 100%, CTC Grade 2 in 54% and CTC Grade 3 in 30% of the cases. All side effects regressed under simple local measures without further complications. Late sequelae were observed in three cases. Overall cosmetic outcome was good to excellent in almost all patients (98%). In two cases (2%) a local recurrence was observed 6 and 20 months after radiotherapy. Conclusion: External beam (orthovoltage) radiotherapy is very effective and yields high tumor control rates and good cosmetic results in long-term follow-up. Former dermatological treatment concepts should be replaced by an ICRU-based radiophysical dose prescription and should respect the newer radiobiological fractionation principles. (orig.)

    Full Text Available INTRODUÇÃO: Aproximadamente 80% das neoplasias malignas de pele não-melanomas são carcinomas basocelulares (CBC. Apesar das raras metástases, esses tumores são localmente agressivos. As metaloproteinases de matriz (MMPs, especialmente as MMP-2 e 9, são importantes no processo de invasão. Em contrapartida, os inibidores teciduais das MMPs (TIMPs têm como principal função a inibição dessas enzimas. OBJETIVO: Investigar a associação de variáveis clinicopatológicas de pacientes portadores de CBC com a expressão de MMP-2, MMP-9, TIMP-1 e TIMP-2. MATERIAL E MÉTODOS: Foram selecionados 31 casos de CBC, sendo então obtidos, retrospectivamente, os dados referentes a idade, sexo e tamanho da lesão. Cortes histológicos das lesões foram submetidos a reação imuno-histoquímica pela técnica estreptavidina-biotina-peroxidase para detecção dos antígenos de interesse. Índices de imunomarcação foram construídos e comparados com os dados previamente obtidos. RESULTADOS: Observou-se correlação significativa entre idade e tamanho da lesão (R = 0,532; p = 0,008. Não foram observadas correlações significativas entre as outras variáveis e a expressão imuno-histoquímica dos antígenos de interesse. CONCLUSÃO: A expressão das metaloproteinases e de seus inibidores teciduais não parece ser influenciada pelos parâmetros investigados. Estudos adicionais são necessários para melhor compreensão de sua associação com o comportamento biológico do CBC.INTRODUCTION: Approximately 80% of non-melanoma skin neoplasias are basal cell carcinomas (BCC. Although metastasis is rare, BBC carcinomas are locally aggressive tumors. Matrix metalloproteinases (MMPs, mainly MMP-2 and MMP-9, play an important role on the invasion process.

    Nevoid basal cell carcinoma syndrome is an autosomal dominant condition characterized by multiple basal cell carcinomas, skeletal abnormalities and sometimes mental retardation. The large number of tumors, which are often disfiguring, presents extreme difficulties in the treatment of these patients. Microscopically controlled excision, compared to other modalities (radiation therapy, photodynamic therapy, intralesional interferon alpha-2b) offers the highest cure rate. However, because of the large size and involvement of wide areas of the skin, this approach is sometimes impractical. The ultrapulse CO2 laser with high energy and short pulses achieves char-free ablation of the tumors, bloodless surgical field, minimal nonspecific thermal damage, rapid healing and diminished postoperative pain. Also, a number of lesions can be removed in a single session. We present a 48-year-old man with a 6.5 x 4.5 cm large basal cell carcinoma involving the anterior abdomen and navel area. The central thick portion of the tumor was resected by microscopically controlled excision with 3 stages, and wide thinner peripheral crescentic plaque vaporized with ultrapulse CO2 laser. The laser settings were 300 mJ energy/pulse and 100 W average power, which corresponds to the fluence of 7.5 J/cm2. Computerized pattern generator (ultrascan handpiece) was adjusted to patterns of 3 (circle) and 1 (square) with sizes varying from 5 to 7, and density of 9 (60% overlapping). The tumor was vaporized with 6 passes, all the way to deep reticular dermis. A fifteen month-follow up disclosed no recurrent disease. Subsequent biopsies revealed only a scar with postinflammatory hyperpigmentation. Our experience indicates that combined treatment with microscopically controlled excision and ultrapulse CO2 laser ablation is a suitable modality for the large tumor plaques involving concave and convex areas of the skin respectively. Microscopically controlled excision of thicker, concave portions of basal

    Full Text Available Background: Basal cell carcinoma (BCC is the most common skin cancer among Caucasians, and in most cases, occurs in the sun-exposed areas. In recent years, in addition to many other etiologies such as exposure to UV radiation, and occasionally xeroderma pigmentosa, burns, tattoos, and pox scars, human papillomavirus (HPV is also considered to have an etiologic role. Different studies were conducted with varied results in this regard. Aims: We evaluate this plausible relationship between HPV and BCC by means of immunohistochemistry (IHC staining method. Methods: This is an analytic cross-sectional study in which 160 samples were selected randomly consisting of 80 BCC lesions and 80 safe margins. Sampling was done among paraffin-embedded blocks in pathology ward of Kashani and Alzahra hospitals, Isfahan-Iran, from 2004-2007. A section of each block was IHC stained for HPV immunoreactivity (DAKO, Denmark. This was followed by microscopic evaluation in terms of being positive or negative. Results: Fifty seven point five percent of the samples belonged to men and the others to women. In 10%, HPV marker was positive, both in lesion and margin. In 83.8% neither the lesions nor the margins were immunoreactive for HPV. Only in 5 cases (6.3% the lesion was positive and the margin was negative for this marker. There was no case of immunoreactivity for HPV marker in margins, while it was negative in lesions. Our study results followed by McNemar analysis did not show a significant relationship between BCC incidence and HPV existence. This was consistent in both genders ( P > 0.05, power > 90%. Conclusion: In this study we did not find a significant relationship between BCC and HPV, but based on review of articles it appears that large multicentric studies are to be conducted in this regard.

Estudos que utilizam recursos da biologia molecular e genética, associados à histomorfologia, permitem a identificação de fatores de risco no desenvolvimento de lesões mais recorrentes e agressivas. OBJETIVO: Correlacionar a expressão dos marcadores de apoptose (p53 e Bcl-2 e proliferação celular (Ki-67 e PCNA com os indicadores histológicos de gravidade do tumor. MÉTODOS: Estudaram-se cinco amostras das formas nodular, morfeiforme e superficial, respectivamente, e um grupo-controle com três pacientes livres de lesão. Empregou-se o teste de Mann-Whitney na comparação da expressão desses marcadores com a forma de apresentação do carcinoma basocelular. RESULTADOS: Verificou-se que a marcação do Bcl-2 foi expressiva nos CBCs ditos agressivos (variantes morfeiforme e nodular. Dos tumores estudados, 66,7% (n = 10 indicaram fortemente o p53. Nossos resultados mostram maior expressão do Ki-67 no carcinoma basocelular nodular e superficial, sem expressão nos controles. O PCNA mostrou forte marcação em todos os tipos de tumores e nos controles. CONCLUSÃO: Os achados nos permitem concluir que o Bcl-2 e o p53 apresentam tendência para diagnosticar gravidade do carcinoma basocelular e o Ki-67, por seu comportamento variável, não pode ser considerado como marcador de gravidade, assim como o PCNA, que não foi um bom marcador de proliferação celular.BACKGROUND: - Basal cell carcinoma is the most common form of human cancer.

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

    International Nuclear Information System (INIS)

    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

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.

    Objective This study aimed to investigate the expression and significance of PIN2/TERF1 interacting, telomerase inhibitor 1 (PinX1) and human telomerase reverse transcriptase (hTERT) in basal cel carcino-ma (BCC). Methods Real-time polymerase chain reaction and immunohistochemistry were performed to quantify the mRNA expressions and integrated optical density (IOD), respectively, of PinX1 and hTERT in BCC specimens (n = 30), as wel as in normal skin specimens (n = 15). Results The mRNA expression level and IOD of PinX1 in the BCC samples were both significantly lower than those in the control specimens (P 0.05). Conclusion Downregulation of PinX1 and upregulation of hTERT expression may be associated with the activation and maintenance of telomerases in the induction of BCC.

    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.

  16. Patterns and timing of sunlight exposure and risk of basal cell and squamous cell carcinomas of the skin – a case–control study

    International Nuclear Information System (INIS)

    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. 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. 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. 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

    Full Text Available The review deals with the results of clinical and experimental studies of the original Russian drug glyciphon used to treat basal cell carcinoma (BCC. Glyciphon is diglycidyl ether of methylphosphonic acid, which has been synthesized at the A. E. Arbuzov Institute of Organic and Physical Chemistry, Kazan Research Center, Russian Academy of Sciences, belongs to a class of organophosphors epoxides. The drug has been experimentally tested by Kazan scientists who revealed the selectivity of its antiblastoma activity, relatively low toxicity, and high safety when it was used long. The antiproliferatve activity of glyciphon in inhibiting DNA synthesis, retarding all mitotic phases, and blocking the entry of cells into S and M phases plays an important role in its mechanism of antiblastoma action. Glyciphon ointment 30 % is effective in the treatment of primary BCC (solitary tumors and polyneoplasms and its recurrences after radiation and surgery in the absence of a side skin resorption effect. It may be successfully used to treat BCC that are refractory to radiotherapy and surgical dissection and to detect latent foci of multiple BCC. The ointment is registered as an agent for the treatment of Stage I squamous cell carcinoma, as well as basaliomas (including recurrences after surgery and radiotherapy, Bowen,s disease, senile keratosis.

    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.

    Salivary gland basaloid neoplasms are diagnostically challenging. Limited publications report that some basal cell adenomas harbor CTNNB1 mutations, and nuclear β-catenin expression is prevalent. We evaluated β-catenin expression in basal cell adenomas and adenocarcinomas in comparison with salivary tumors in the differential diagnosis and performed targeted genetic analysis on a subset of cases. β-catenin immunohistochemistry was performed on formalin-fixed, paraffin-embedded whole sections from 73 tumors. Nuclear staining was scored semiquantitatively by extent and intensity. DNA was extracted from 6 formalin-fixed, paraffin-embedded samples (5 basal cell adenomas, 1 basal cell adenocarcinoma) for next-generation sequencing. Nuclear β-catenin staining was present in 18/22 (82%) basal cell adenomas; most were diffuse and strong and predominant in the basal component. Two of 3 basal cell adenocarcinomas were positive (1 moderate focal; 1 moderate multifocal). All adenoid cystic carcinomas (0/20) and pleomorphic adenomas (0/20) were negative; 2/8 epithelial-myoepithelial carcinomas showed focal nuclear staining. Most β-catenin-negative tumors showed diffuse membranous staining in the absence of nuclear staining. Four of 5 basal cell adenomas had exon 3 CTNNB1 mutations, all c.104T>C (p.I35T). Basal cell adenocarcinoma showed a more complex genomic profile, with activating mutations in PIK3CA, biallelic inactivation of NFKBIA, focal CYLD deletion, and without CTNNB1 mutation despite focal β-catenin expression. Nuclear β-catenin expression has moderate sensitivity (82%) for basal cell adenoma but high specificity (96%) in comparison with its morphologic mimics. CTNNB1 mutation was confirmed in most basal cell adenomas tested, and findings in basal cell adenocarcinoma suggest possible tumorigenic mechanisms, including alterations in PI3K and NF-κB pathways and transcriptional regulation.

    2015-01-01

    Abstract Background: 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. Methods: 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. Results: 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 < 0.05). Conclusions: BCC arising in embryologic fusion 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.

    Full Text Available Photodynamic therapy (PDT with aminolevulinic acid (ALA to treat nodular basal cell carcinoma (BCC has been shown to be beneficial. The success rate of ALA-PDT in the treatment of nodular BCC is dependent on optimal penetration of the photosensitizing agent and subsequent PpIX production. To enhance topical delivery of drugs intradermally, a needleless jet injection (NLJI, which employs a high-speed jet to puncture the skin without the side effects of needles, was used in one patient with recurrent BCC of the nose. Photoactivation was then performed using red light emitting diode [CW @ λ 630 nm, irradiance 50 mW/cm2, total fluence 51 J/cm2] for 17 minutes. Excellent cosmesis was obtained. Aside from mild crusting present for six days, no other adverse signs were noted. Clinically, there was no recurrent lesion up two years postintervention. Additional studies in larger samples of subjects are needed to further evaluate this promising technique.

    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.

  6. Hedgehog pathway inhibitor in combination with radiation therapy for basal cell carcinomas of the head and neck. First clinical experience with vismodegib for locally advanced disease

    International Nuclear Information System (INIS)

    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.)

    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.

    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.

    tumor that contains a mixture of malignant cells with squamous and glandular differentiation. The literature points to the importance of making this diagnosis when the cellular components are still well differentiated in the sample, otherwise the tumor may be erroneously interpreted as squamous carcinoma or adenocarcinoma. This study describes an unusual presentation of a adenosquamous carcinoma in a 47 year old patient. After conflicting cytological diagnoses and a history of abnormal uterine bleeding caused by cervical endometriosis, the patient was subjected to radical hysterectomy and a final diagnosis was obtained. The tumor was diagnosed as adenosquamous carcinoma. In many aspects, however, it was similar to the adenoid basal carcinoma. Characteristic features of the adenoid basal carcinoma such as the presence of high-grade squamous intraepithelial lesion in the surface epithelium, squamous and glandular differentiation in the center of the neoplastic mass, and basaloid cells in deep areas of the tumor were observed. Therefore, the following elements usually absent from adenoid basal carcinoma were present in this case: atypia and mitotic figures in undifferentiated cells, squamous-mucinous intraepithelial lesion (SMILE in the superficial areas. Epidemiological and clinical data, such as patient age (47, race (white and presentation (a cervical mass, concurred to exclude the diagnosis of adenoid basal carcinoma. Other differential diagnoses include pure squamous carcinoma or adenocarcinoma, collision tumor, and endometrial adenocarcinoma with squamous differentiation invading the uterine cervix.

    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.

    Full Text Available Abstract Background The SINS trial (Controlled Clinical Trials ISRCTN48755084; Eudract No. 2004-004506-24 is a randomised controlled trial evaluating long term success of excisional surgery vs. imiquimod 5% cream for low risk nodular and superficial basal cell carcinoma (BCC. The trial included a discrete choice experiment questionnaire to explore patient preferences of a cream versus surgery for the treatment of their skin cancer. Methods The self-completed questionnaire was administered at baseline to 183 participants, measuring patients’ strength of preferences when choosing either alternative ‘surgery’ or ‘imiquimod cream’ instead of a fixed ‘current situation’ option (of surgical excision as standard practice in UK. The treatments were described according to: cost, chance of complete clearance, side effects and appearance. Participants had to choose between various scenarios. Analysis was performed using a mixed logit model, which took into account the impact of previous BCC treatment and sample preference variability. Results The analysis showed that respondents preferred ‘imiquimod cream’ to their ‘current situation’ or ‘surgery’, regardless of previous experience of BCC symptoms and treatment. Respondents were more likely to be worried about their cosmetic outcomes and side effects they might experience over and above their chance of clearance and cost. Those with no experience of surgery (compared with experience valued more the choice of ‘imiquimod cream’ (£1013 vs £781. All treatment characteristics were significant determinants of treatment choice, and there was significant variability in the population preferences for all of them. Conclusions Patients with BCC valued more ‘imiquimod cream’ than alternative ‘surgery’ options, and all treatment characteristics were important for their choice of care. Understanding how people with a BCC value alternative interventions may better inform the

    Skin cancer, the most common cancer in the general population, is strongly associated with exposure to the ultraviolet component of sunlight. To investigate the relationship between DNA damage processing and skin tumour development, we determined the POLH status of a cohort of skin cancer patients. The human POLH gene encodes DNA polymerase eta (poleta), which normally carries out accurate translesion synthesis past the major UV-induced photoproduct, the dithymine cyclobutane dimer. In the absence of active poleta in xeroderma pigmentosum variant (XPV) patients, mutations accumulate at sites of UV-induced DNA damage, providing the initiating step in skin carcinogenesis. Forty patients diagnosed with skin cancer were genotyped for polymorphisms in the POLH protein-coding sequence, using glycosylase-mediated polymorphism detection (GMPD) and direct DNA sequencing of POLH PCR products derived from white blood cell genomic DNA. All individuals carried the wild-type POLH sequence. No POLH mutations were identified in genomic DNA from skin tumours derived from 15 of these patients. As determined by RT-PCR, POLH mRNA was expressed in all normal and skin tumour tissue examined. Poleta protein was also detectable by Western blotting, in two matched normal and skin tumour extracts. An alternatively spliced form of POLH mRNA, lacking exon 2, was more readily detected in skin tissue than in white blood cells from the same patient. Real-time PCR was used to quantify POLH expression in matched normal and skin tumour-derived mRNA from a series of patients diagnosed with either basal or squamous cell carcinoma. Compared to matched normal skin tissue from the same patient, 1 of 7 SCC, and 4 of 10 BCC tumours examined showed at least a 2-fold reduction in POLH expression, while 1 of 7 SCC, and 3 of 10 BCC tumours showed at least a 2-fold increase in POLH expression. Differences in gene expression, rather than sequence changes may be the main mechanism by which POLH status varies

    Full Text Available Myiasis is a disease caused by infestation of fly larvae in human and other vertebrate tissues. It is a skin condition common in tropical and subtropical countries and its predisposing factors are: chronic diseases, immunodeficiency, poor hygiene, senility, psychiatric disorders, skin cancers and ulcerated mucosae. We report the case of a healthy patient who after traumatic injury of a preexisting lesion showed a tumor on the dorsal region parasitized by fly larvae. The histopathological examination performed for the diagnosis of skin neoplasm surprisingly revealed the presence of a partially degenerated larva with characteristics of Dermatobia hominis, suggesting an association of primary and secondary myiasis on basal cell carcinoma.A miíase é uma doença causada por infestação de larvas de moscas nos tecidos humanos ou de outros animais vertebrados.

    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.)

    A randomized controlled trial including 601 patients previously showed that the effectiveness of imiquimod and fluorouracil cream were not inferior to methyl aminolevulinate photodynamic therapy (MAL-PDT) in patients with superficial basal cell carcinoma after 1 year of follow-up. We now present the 3-year follow-up results. The probability of tumor-free survival at 3 years post-treatment was 58.0% for MAL-PDT (95% confidence interval [CI] = 47.8-66.9), 79.7% for imiquimod (95% CI = 71.6-85.7), and 68.2% for fluorouracil (95% CI = 58.1-76.3). The hazard ratio for treatment failure comparing imiquimod with MAL-PDT was 0.50 (95% CI = 0.33-0.76, P = 0.001). Comparison of fluorouracil with MAL-PDT and fluorouracil with imiquimod showed hazard ratios of 0.73 (95% CI = 0.51-1.05, P = 0.092) and 0.68 (95% CI = 0.44-1.06, P = 0.091), respectively. Subgroup analysis showed a higher probability of treatment success for imiquimod versus MAL-PDT in all subgroups with the exception of elderly patients with superficial basal cell carcinoma on the lower extremities. In this subgroup, the risk difference in tumor-free survival was 57.6% in favor of MAL-PDT. In conclusion, according to results at 3 years post-treatment, imiquimod is superior and fluorouracil not inferior to MAL-PDT in treatment of superficial basal cell carcinoma. PMID:27113429

    Full Text Available OBJECTIVES: Biological markers that predict the development of invasive breast cancer are needed to improve personalized therapy for patients diagnosed with ductal carcinoma in situ. We investigated the role of basal cytokeratin 5/6 in the risk of invasion in breast ductal carcinoma in situ. METHODS: We constructed tissue microarrays using 236 ductal carcinoma in situ samples: 90 pure samples (group 1 and 146 samples associated with invasive carcinoma (group 2. Both groups had similar nuclear grades and were obtained from patients of similar ages. The groups were compared in terms of estrogen (ER and progesterone receptor (PR status, human epidermal growth factor receptor 2 (HER2 expression, cytokeratin 5/6 immunostaining, human epidermal growth factor receptor 1 (EGFR membrane staining and molecular subtype, as indicated by their immunohistochemistry profiles. RESULTS: ER/PR-negative status was predictive of invasion, whereas HER2 superexpression and cytokeratin 5/6-positive status were negatively associated with invasion. Among the high-grade ductal carcinoma in situ cases, a triple-positive profile (positive for estrogen receptor, progesterone receptor, and HER2 and cytokeratin 5/6 expression by neoplastic cells were negatively associated with invasion. In the low-grade ductal carcinoma in situ subgroup, only cytokeratin 5/6 expression exhibited a negative association with the probability of invasion. CONCLUSION: The immunohistochemical expression of cytokeratin 5/6 by ductal carcinoma in situ epithelial cells may provide clinically useful information regarding the risk of progression to invasive disease.

    Purpose To investigate the clinicopathologic features of cervical adenoid basal cell carcinoma. Methods Clinical and pathological data were analyzed in 12 cases of cervical adenoid basal cell carcinoma and the relevant literatures were reviewed. Results The age of 12 cases of with cervical adenoid basal cell cancer patients ranged from 36~70 years ( mean:53. 3 years) , with a medi-an age of 51. 5 years. Amongst 12 patients who contained no gross definite lesion, 5 patients (41. 7%) had the symptoms of vaginal bleeding. 8 cases of patients underwent hysterectomy, while the other four received cervical conization. Cervical intraepithelial neopla-sia ( CIN) lesions were observed in all 12 cases. The tumor cells were small and uniform, with dark oval nuclei without conspicuous nucleoli and scanty cytoplasm. Tumor infiltrated into the stroma in nests and cords. Glandular differentiation within tumor nests were seen in 12 cases, including two cases of squamous cell differentiation accompanied by partial and minor interstitial edema. Peripheral palisading cells around tumor nests were also found. The infiltrating depth of tumor ranged from 0. 5~10 mm with the average 4. 12 mm.

    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 Chronic lymphedema presents as interstitial fluid retention due to a failure in the lymphatic system drainage. The affected region becomes more vulnerable immunologically and predisposed to the onset of neoplasms. Basal Cell Carcinoma is the most common sort of neoplasm, nevertheless it rarely metastisizes. Sarcomas are malignant mesenchymal neoplasms, locally aggressive, which can spread. Here is reported an infrequent case of multiple basal cell carcinoma, synchronous to a poorly differentiated pleomorphic sarcoma, both spreading to lymph nodes and arising from tissue compromised by chronic lymphedema.Linfedema crônico se manifesta pelo acúmulo de líquido intersticial por falha da drenagem linfática. A região afetada torna-se imunologicamente vulnerável e predisposta ao desenvolvimento de neoplasias. Carcinoma basocelular é a neoplasia maligna mais comum, entretanto raramente metastatiza. Sarcomas são neoplasias mesenquimais malignas, localmente agressivas e capazes de metastatizar. Apresentamos um caso raro de múltiplos carcinomas basocelulares concomitantes a sarcoma pleomórfico pouco diferenciado, metastáticos para linfonodos, originando-se em área de linfedema crônico.

    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 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.

    Sarcomatoid renal cell carcinoma (SRCC) is an aggressive tumor variant thought to arise predominantly from differentiation of clear cell carcinoma. A few reports of SRCC asso-ciated with non-clear cell tumors led to the presumption that SRCC may arise from any renal cell carcinoma, although direct evidence of this is lacking. We report a case of a 70-year-old male patient, who presented with acute left upper quadrant abdominal pain and was diagnosed to have SRCC after pathological examination...

  1. Undifferentiated Carcinoma of the Endometrium: An Expanded Immunohistochemical Analysis Including PAX-8 and Basal-Like Carcinoma Surrogate Markers.

    Undifferentiated carcinoma of the endometrium (UCAe) is an aggressive, underrecognized high-grade carcinoma that can occur either in pure form or in conjunction with low-grade endometrioid adenocarcinoma (i.e. dedifferentiated carcinoma). The typical solid growth pattern of UCAe can create a diagnostic dilemma as it is frequently misinterpreted as the solid component of an endometrial carcinoma or as a sarcoma. In addition, the high nuclear:cytoplasmic ratio, high mitotic index, and geographic necrosis are reminiscent of basal-like carcinoma of breast (BLCB). This study was undertaken to determine the role of a selected group of immunomarkers in the distinction of UCAe from other endometrial carcinomas, and assess the expression of DNA mismatch repair proteins, and surrogate BLCB immunomarkers in this type of tumor. Cases of UCAe were stained with antibodies against keratin cocktail, CK8/18, PAX-8, and estrogen receptor: 35 cases; progesterone receptor and Her-2/neu: 33 cases; CD44, e-cadherin, p16, and p53: 32 cases; and CK5/6, EGFR, and c-Kit: 18 cases. In addition, mismatch repair protein markers MLH1, MSH2, MSH6, and PMS2 were performed in 34 cases. We found that PAX-8 expression was lost in most cases (83%). In addition, estrogen and progesterone receptors were negative in 83% and 82% of cases, respectively. Seventy-seven percent of cases were positive for keratin cocktail and keratin 8/18, whereas only 11% of cases were positive for keratin 5/6. p16 was diffusely positive in 34% of cases, whereas p53 was expressed in >75% of the tumor cells in 31% of cases. MLH1 and PMS2 were concurrently lost in 50% of cases, whereas MSH2 and MSH6 were lost in 1 case (3%). E-cadherin and CD44 were completely lost in 50% of cases, whereas Her-2/neu was negative in all cases. EGFR was negative in 67% of cases, whereas 22% of cases showed diffuse membranous staining for this marker. UCAe is a high-grade carcinoma of Müllerian origin which tends to be negative for PAX-8.

    Full Text Available Neurofibromatosis I (NF I, an autosomal dominant disorder is associated with increased risk of benign and malignant peripheral nerve sheath tumors and central nervous system tumors. There are only few case reports of breast carcinoma in known patients of NF I. We report a case of basal like carcinoma of the breast in a 69-year-old lady who had NF I. Considering the rare association of carcinomas with NF I and finding that both the NF I gene and a breast cancer pre-disposition gene, BRCA 1 are located in close proximity on chromosome 17q makes the association of these two conditions intriguing.

  4. Nanoelectroablation therapy for murine basal cell carcinoma

    International Nuclear Information System (INIS)

    Highlights: ► Nanoelectroablation is a new, non-thermal therapy that triggers apoptosis in tumors. ► Low energy, ultrashort, high voltage pulses ablate the tumor with little or no scar. ► Nanoelectroablation eliminates 99.8% of the BCC but may leave a few remnants behind. ► 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+/−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) mm3 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.

    Basal cell carcinoma has much difference with trichoblastoma in therapy and prognosis. In the past years, due to the lack of definite classification and distinctions of basal cell carcinoma and trichoblastoma, misdiagnosis and mismanagement were often encountered and the patients underwent inappropriate treatment. So we must differentiate basal cell carcinoma from trichoblastoma early and accurately. It is difficult to distinguish them distinctly only by clinical presentation and pathologic features. In recent years, with the development of molecular biology, research in immunohistochemisty and genetics have increased, and provide us some new identification. This review article mainly describes the recent development of molecular biological markers AR, CD10, Ln5γ2, Nestin, PHLDAl and CK20 for the differential diagnosis of basal cell carcinoma and trichoblastoma.%基底细胞癌与毛母细胞瘤在治疗和预后方面有很大的不同。过去由于对两者的分类和诊断比较混乱,给临床治疗带来诸多不便,也给患者增加了不必要的痛苦。这就要求临床医师能及时、准确、有效地鉴别诊断基底细胞癌和毛母细胞瘤。临床上,尤其在病理上,明确鉴别两者很困难。近些年,随着分子生物学技术的发展,从免疫组织化学和遗传学等方面对两者的研究增多,为我们提供一些新的鉴别依据。本文综述几种近年来研究较多的用于两者鉴别诊断的分子生物学标记物AR、CD10、Ln5γ2、Nestin、PHLDAl和CK20的进展。

  13. Papillary renal cell carcinoma

    International Nuclear Information System (INIS)

    Between 1976 and 1987, 395 patients with kidney tumors were studied with radiological techniques and sonography. In 37 cases (9.4%) histopathology diagnosed pure papillary renal cell carcinoma. Analyzing the radiographic patterns of these neoplasms, the authors observed constantly diminished vascularity (100%) frequent calcifications (35.1%) and necrotic areas (51.3%). Such X-ray features are not specific: nevertheless, their coexistence is strongly suggestive of papillary renal cell cancer. No consistent US pattern was found; however, necrotic areas were easily demonstrated in most cases. It must be stressed how patients with papillary carcinoma experienced a longer post-operative survival; it has not yet been established whether such favorable behavior is due to low biological aggressiveness or to earlier diagnosis

    Basal cell nevus syndrome, also known as Gorlin-Goltz syndrome, is an autosomal dominant inherited disorder which is characterised by the presence of multiple maxillary keratocysts and facial basal cell carcinomas, along with other less frequent clinical characteristics such us musculo-skeletal disturbances (costal and vertebrae malformations), characteristic facies, neurological (calcification of the cerebral falx, schizophrenia, learning difficulties), skin (cysts, lipomas, fibromas), sight, hormonal, etc. On occasions it can be associated with aggressive basal cell carcinomas and malignant neoplasias, for which early diagnosis and treatment is essential, as well as family detection and genetic counselling. Currently there are new lines of investigation based on biomolecular studies, which aim at identifying the molecules responsible for these cysts and thus allowing an early diagnosis of these patients. In its clinical management and follow up, the odonto-stomatologist, the maxillofacial surgeon and several other medical specialists are involved. In this paper a review of the literature, and six cases of patients affected by multi-systemic and varied clinical expression of basal cell nevus syndrome, are presented. PMID:15800468

    Full Text Available Mesothelin is a cell surface associated antigen expressed on mesothelial cells and in some malignant neoplasms. Mesothelin-targeted therapies are in phase I/II clinical trials. The clinicopathologic and prognostic significance of mesothelin expression in triple negative breast carcinomas (TNBC has not been fully assessed. We evaluated the expression of mesothelin and of basal markers in tissue microarrays of 226 TNBC and 88 non-TNBC and assessed the clinicopathologic features of mesothelin-expressing breast carcinomas. Furthermore, we investigated the impact of mesothelin expression on the disease-free and overall survival of patients with TNBC. We found that mesothelin expression is significantly more frequent in TNBC than in non-TNBC (36% vs 16%, respectively; p = 0.0006, and is significantly correlated with immunoreactivity for basal keratins, but not for EGFR. Mesothelin-positive and mesothelin-negative TNBC were not significantly different by patients' race, tumor size, histologic grade, tumor subtype, lymphovascular invasion and lymph node metastases. Patients with mesothelin-positive TNBC were older than patients with mesothelin-negative TNBC, developed more distant metastases with a shorter interval, and had significantly lower overall and disease-free survival. Based on our results, patients with mesothelin-positive TNBC could benefit from mesothelin-targeted therapies.

  4. Isolation of basal and mucous cell populations from rabbit trachea

    International Nuclear Information System (INIS)

    The application of a unit gravity sedimentation procedure to monodispersed rabbit tracheal cells resulted in the isolation of enriched (2-fold to 2.5-fold) basal and mucous cell populations. Cellular integrity was confirmed by a trypan blue dye exclusion index of 93%, [3H] leucine incorporation, and ultrastructural analysis. Unit gravity sedimentation is an affective and rapid procedure for obtaining viable, homogeneous preparations of basal and mucous cells that may be used for in vitro studies of cellular proliferation, differentiation, and glycoprotein biosynthesis in respiratory mucous epithelia

  6. Ancestral vascular lumen formation via basal cell surfaces.

    Directory of Open Access Journals (Sweden)

    Tomás Kucera

    Full Text Available The cardiovascular system of bilaterians developed from a common ancestor. However, no endothelial cells exist in invertebrates demonstrating that primitive cardiovascular tubes do not require this vertebrate-specific cell type in order to form. This raises the question of how cardiovascular tubes form in invertebrates? Here we discovered that in the invertebrate cephalochordate amphioxus, the basement membranes of endoderm and mesoderm line the lumen of the major vessels, namely aorta and heart. During amphioxus development a laminin-containing extracellular matrix (ECM was found to fill the space between the basal cell surfaces of endoderm and mesoderm along their anterior-posterior (A-P axes. Blood cells appear in this ECM-filled tubular space, coincident with the development of a vascular lumen. To get insight into the underlying cellular mechanism, we induced vessels in vitro with a cell polarity similar to the vessels of amphioxus. We show that basal cell surfaces can form a vascular lumen filled with ECM, and that phagocytotic blood cells can clear this luminal ECM to generate a patent vascular lumen. Therefore, our experiments suggest a mechanism of blood vessel formation via basal cell surfaces in amphioxus and possibly in other invertebrates that do not have any endothelial cells. In addition, a comparison between amphioxus and mouse shows that endothelial cells physically separate the basement membranes from the vascular lumen, suggesting that endothelial cells create cardiovascular tubes with a cell polarity of epithelial tubes in vertebrates and mammals.

  9. Luminal and basal-like breast cancer cells show increased migration induced by hypoxia, mediated by an autocrine mechanism

    International Nuclear Information System (INIS)

    Some breast cancer patients receiving anti-angiogenic treatment show increased metastases, possibly as a result of induced hypoxia. The effect of hypoxia on tumor cell migration was assessed in selected luminal, post-EMT and basal-like breast carcinoma cell lines. Migration was assessed in luminal (MCF-7), post-EMT (MDA-MB-231, MDA-MB-435S), and basal-like (MDA-MB-468) human breast carcinoma cell lines under normal and oxygen-deprived conditions, using a collagen-based assay. Cell proliferation was determined, secreted cytokine and chemokine levels were measured using flow-cytometry and a bead-based immunoassay, and the hypoxic genes HIF-1α and CA IX were assessed using PCR. The functional effect of tumor-cell conditioned medium on the migration of neutrophil granulocytes (NG) was tested. Hypoxia caused increased migratory activity but not proliferation in all tumor cell lines, involving the release and autocrine action of soluble mediators. Conditioned medium (CM) from hypoxic cells induced migration in normoxic cells. Hypoxia changed the profile of released inflammatory mediators according to cell type. Interleukin-8 was produced only by post-EMT and basal-like cell lines, regardless of hypoxia. MCP-1 was produced by MDA-MB-435 and -468 cells, whereas IL-6 was present only in MDA-MB-231. IL-2, TNF-α, and NGF production was stimulated by hypoxia in MCF-7 cells. CM from normoxic and hypoxic MDA-MB-231 and MDA-MB-435S cells and hypoxic MCF-7 cells, but not MDA-MB-468, induced NG migration. Hypoxia increases migration by the autocrine action of released signal substances in selected luminal and basal-like breast carcinoma cell lines which might explain why anti-angiogenic treatment can worsen clinical outcome in some patients

    Full Text Available The association of squamous cell carcinoma of the larynx with thyroid papillary carcinoma is an unusual finding. From 2004 to 2011, approximately 250 patients underwent laryngectomies due to squamous cell carcinoma of the larynx at the Otolaryngology Department of Khalili Hospital, affiliated with Shiraz University of Medical Sciences, Shiraz, Iran. In three patients, synchronous occurrence of squamous cell carcinoma and thyroid papillary carcinoma was found. Histopathologic study of the lymph nodes revealed metastatic papillary thyroid carcinoma in one case. We report three cases of thyroid papillary carcinoma incidentally found on histological examinations of resected thyroid lobes, as a procedure required for treatment of head and neck squamous cell carcinoma. In comparison, laryngeal squamous cell carcinoma needs more aggressive treatment than well-differentiated thyroid carcinoma. The prevalence of thyroid papillary carcinoma, as an incidental finding in our study was 0.01%. Therefore, preoperative evaluation of the thyroid gland by ultrasonography and fine needle aspiration biopsy of suspicious lesions is recommended in patients who are candidates for open laryngectomy.

  12. Recurrent peripheral odontogenic fibroma associated with basal cell budding

    2014-01-01

    Full Text Available Peripheral odontogenic fibroma (POdF is a rare benign odontogenic neoplasm. It represents the soft tissue counterpart of central odontogenic fibroma. The embryonic source of POdF has been suggested by many as arising from the rest of dental lamina that has persisted in the gingiva following its disintegration. It presents clinically as a firm, slow growing and sessile gingival mass, which is difficult to distinguish with more common inflammatory lesions. Very few cases of recurrence have been documented. It has been stated that histological budding of basal cell layer of the surface squamous epithelium is associated with higher recurrence and the presence of calcification in direct apposition to the epithelial rest is associated with lower recurrence. Hereby, we present a case which histologically exhibited budding of the basal cell layer, which could have been the reason for its recurrence.

Hepatitis B basal core promoter mutants, precore mutants, genotypes,hepatitis B viral DNA (HBV DNA) level and hepatitis B e antigen (HBeAg) were measured. Univariate analysis and logistic regression were used to assess odds ratios for viral factors related to liver deaths and hepatocellular carcinoma development.RESULTS: During follow-up, 38 patients had liver deaths not related to hepatocellular carcinoma. On multivariate analysis, older age [odds ratio: 95.74 (12.13-891.31);P < 0.0001], male sex [odds ratio: 7.61 (2.20-47.95);P = 0.006], and higher log10 HBV DNA [odds ratio:4.69 (1.16-20.43); P < 0.0001] were independently predictive for these liver related deaths. Also, 31 patients developed hepatocellular carcinoma. Multivariate analysis showed that older age [odds ratio: 26.51 (2.36-381.47);P = 0.007], presence of precore mutants [odds ratio:4.23 (1.53-19.58); P = 0.02] and presence of basal core promoter mutants [odds ratio: 2.93 (1.24-7.57); P =0.02] were independent predictors for progression to hepatocellular carcinoma.CONCLUSION: Our results show that high levels of baseline serum HBV DNA are associated with nonhepatocellular carcinoma-related deaths of liver failure,while genetic mutations in the basal core promoter and precore regions are predictive for development of hepatocellular carcinoma.

    Merkel cell carcinoma is a rare aggressive neuroendocrine carcinoma of the skin predominantly affecting elderly Caucasians. It has a high rate of local recurrence and regional lymph node metastases. It is associated with a poor prognosis. Complete spontaneous regression of Merkel cell carcinoma has been reported but is a poorly understood phenomenon. Here we present a case of complete spontaneous regression of metastatic Merkel cell carcinoma demonstrating a markedly different pattern of events from those previously published.

  1. MRI analysis of renal cell carcinoma

    International Nuclear Information System (INIS)

    Objective: To analyze MRI manifestation and enhancement of renal cell carcinoma, and to improve the diagnosis of renal cell carcinoma. Methods: 48 cases of renal cell carcinoma proven by surgery and pathology were reviewed. MRI scans including T1WI, T2WI, TRUFI and contrast enhancement were carried out in all cases and dynamic contrast-enhanced MRI was performed in 15. Results: Of the 48 cases, there were clear cell carcinoma in 41, chromophobe cell carcinoma in 4 and papillary cell carcinoma in 3. The tumors were homogeneously T1 iso- or hypointense in 33 and heterogeneous in 15; homogeneously T2 hyperintense in 14, isointense in 6 and heterogeneous in 28 patients. Pseudocapsule was found in 10 cases. Contrast enhancement was homogeneous in 6, heterogeneous in 34, irregularly peripheral within the wall in 5, and homogeneously circular in 3. Conclusion: MRI can accurately diagnose renal cell carcinoma and help to determine the cell subsets. (authors)

    Full Text Available PURPOSE: To assess the current treatment of metastatic renal cell carcinoma, focusing on medical treatment options. MATERIAL AND METHODS: The most important recent publications have been selected after a literature search employing PubMed using the search terms: advanced and metastatic renal cell carcinoma, anti-angiogenesis drugs and systemic therapy; also significant meeting abstracts were consulted. RESULTS: Progress in understanding the molecular basis of renal cell carcinoma, especially related to genetics and angiogenesis, has been achieved mainly through of the study of von Hippel-Lindau disease. A great variety of active agents have been developed and tested in metastatic renal cell carcinoma (mRCC patients. New specific molecular therapies in metastatic disease are discussed. Sunitinib, Sorafenib and Bevacizumab increase the progression-free survival when compared to therapy with cytokines. Temsirolimus increases overall survival in high-risk patients. Growth factors and regulatory enzymes, such as carbonic anhydrase IX may be targets for future therapies. CONCLUSIONS: A broader knowledge of clear cell carcinoma molecular biology has permitted the beginning of a new era in mRCC therapy. Benefits of these novel agents in terms of progression-free and overall survival have been observed in patients with mRCC, and, in many cases, have become the standard of care. Sunitinib is now considered the new reference first-line treatment for mRCC. Despite all the progress in recent years, complete responses are still very rare. Currently, many important issues regarding the use of these agents in the management of metastatic renal cancer still need to be properly addressed.

  3. Inverting adherent cells for visualizing ECM interactions at the basal cell side

    International Nuclear Information System (INIS)

    Interactions with the extracellular matrix (ECM) govern a wide range of cellular functions, including survival, migration and invasion. However, in adherent cells these interactions occur primarily on the basal cell side, making them inaccessible to high-resolution, surface-scanning imaging techniques such as atomic force microscopy (AFM) or scanning electron microscopy (SEM). Here we describe a fast and reliable method for inverting adherent cells, exposing the basal cell membrane for direct analysis by AFM or SEM in combination with fluorescence microscopy. Cells including their matrix adhesion sites remain intact during the inversion process and are transferred together with the complete array of basally associated ECM proteins. Molecular features of ECM proteins, such as the characteristic 67 nm collagen D-periodicity, are well preserved after inversion. To demonstrate the versatility of the method, we compared basal interactions of fibroblasts with fibrillar collagen I and fibronectin matrices. While fibroblasts remodel the fibronectin layer exclusively from above, they actively invade even thin collagen layers by contacting individual collagen nanofibrils both basally and apically through a network of cellular extensions. Cell–matrix entanglement coincides with enhanced cell spreading and flattening, indicating that nanoscale ECM interactions govern macroscopic changes in cell morphology. The presented cell inversion technique can thus provide novel insight into nanoscale cell–matrix interactions at the basal cell side. - Highlights: ► We present a novel method for inverting adherent cells to expose the basal cell side. ► Basal cell sides can be imaged at high resolution by AFM and SEM. ► Cells can be inverted together with the underlying extracellular matrix. ► AFM images of inverted cells provide a nanoscale look at basal cell–ECM interactions

  8. Stimulated Tg level measurements may be avoided in differentiated thyroid carcinoma patients who have undetectable basal Tg levels

    International Nuclear Information System (INIS)

    Full text of publication follows. Objective: the aim of this retrospective study is to evaluate the diagnostic value of undetectable basal thyroglobulin (Tg) levels measured 6 months after ablative 131I treatment (AIT) in patients with differentiated thyroid carcinoma (DTC). Materials and methods: the study included 159 patients (140 women, 19 men with, mean age 43.4±15.6 years) who had undetectable basal Tg levels (<0.2 ng/ml) and negative anti-Tg antibodies, 6 months after AIT. Histologic examination was papillary thyroid carcinoma in 151 patients and follicular thyroid carcinoma in 8 patients. To control the AIT efficacy, diagnostic whole body scan (DWBS) was planned 6 months after AIT. Before DWBS, basal and stimulated Tg levels were measured and compared. Then all patients underwent DWBS. Results: all patients (with undetectable basal Tg level) had a stimulated Tg level under 2 ng/ml. Stimulated Tg levels were undetectable (<0.2 ng/ml) in 142 (89.3%) patients and 0.58±0.26 ng/ml (range 0.3-1.3 ng/ml) in 17 (10.7%) patients. The control DWBS, 6 months after thyroid ablation, was negative in 151 (95%) patients and was positive for minimal residual uptake on the thyroid bed in 8 (5%) patients. Stimulated Tg levels of patients with residual thyroid bed uptake on control DWBS, were undetectable (<0.2 ng/ml) in 4 patients and 0.8±0.19 ng/ml (range 0.3-1.3 ng/ml) in 4 patients. Conclusion: our data suggest that stimulated Tg level measurements may be avoided in DTC patients with undetectable basal Tg levels. Thus, unnecessary Tg stimulation with rhTSH or endogen TSH, diagnostic procedures (DWBS) and radiation exposure can be reduced. (authors)

    Basal cell carcinoma (BCC) is one of the commonest malignancies occurred on sun-exposed skin, mainly by UV-B radiation, of lighter-skinned individuals. The aim of the present study was to develop advanced drug delivery formulations used in BCC therapy that overcomes chemotherapy-induced side-effects of skin photosensitivity by an integrative approach of nanoencapsulation in conjunction with combination therapy that uses chemotherapeutic, chemoprotective and sunscreen agents. The combination of anticancer drug together with sunscreen agent is very useful in therapy, especially for individuals who are more exposed to the sun without using a sunscreen. Nanostructured lipid carriers (NLCs) employed as drug delivery systems were co-loaded with 5-fluorouracil (5-FU), a hydrophilic chemotherapeutic drug, and ethylhexyl salicylate (EHS), a lipophilic UV-B sunscreen agent. The NLCs were developed using bioactive squalene (50.8% w/w) from amaranth seed oil as chemoprotective agent. By varying the concentrations of 5-FU and EHS, the co-loaded NLCs presented particle sizes of about 100nm, acceptable physical stability with values smaller than -25mV and appropriate entrapment efficiency that reaches values over 65% for both types of drugs. The UV-B blocking ability of EHS loaded into NLCs were influenced by the concentration of 5-FU. The amaranth oil offered a capacity of 70% in scavenging the free radicals. In vitro drug release showed that NLCs presented sustained release of 5-FU that followed the Fick's law of diffusion. PMID:25828466

    Patients with metastatic renal cell carcinoma continue to present a therapeutic challenge. Current therapeutic approaches involve surgery and various types of immunotherapy. The rationale for this latter form of therapy include the observations of spontaneous tumor regression, the presence of a T-cell-mediated immune response, and the tumor responses observed in patients receiving cytokine therapy. Analysis of prognostic factors in these patients demonstrates that clinical responses occur most frequently in individuals with good performance status. The cytokines interleukin-2 (IL-2, aldesleukin [Proleukin], interferon-alfa (Intron A, Roferon-A), or the combination produce responses in 15% to 20% of patients. Randomized trials suggest that administration of interferon-alfa may result in a modest improvement in median survival. Investigation of the molecular genetics of renal cell carcinoma and the presence of T-lymphocyte immune dysregulation have suggested new therapeutic strategies. Further preclinical and clinical studies investigating inhibitors of angiogenesis or pharmacologic methods to reverse immune dysregulation are ongoing. Therapeutic results in patients with renal cell carcinoma remain limited, and investigational approaches are warranted. PMID:10378218

    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.

    Aberrant sonic hedgehog signalling, mostly due to PTCH1 mutations, has been shown to play a central role in the pathogenesis of basal cell carcinoma (BCC), as well as in basal cell naevus syndrome (BCNS). Mutations in smoothened (SMO) encoding a receptor for sonic hedgehog have been reported in sporadic BCCs but not in BCNS. We report a case with multiple BCCs, pits and comedones in a segmental distribution over the upper part of the body, along with other findings compatible with BCNS. Histopathologically, there were different types of BCC. A heterozygous mutation (c.1234C>T, p.L412F) in SMO was detected in three BCCs but not in peripheral blood lymphocytes or the uninvolved skin. These were compatible with the type 1 mosaic form of BCNS. The p.L412F mutation was found experimentally to result in increased SMO transactivating activity, and the patient responded to vismodegib therapy. Activating mutations in SMO may cause BCNS. The identification of a gain-of-function mutation in SMO causing a type 1 mosaic form of BCNS further expands our understanding of the pathogenesis of BCC, with implications for the treatment of these tumours, whether sporadic or inherited.

    Basal cell carcinoma (BCC) of the skin is the most common cancer, with a higher incidence than all other malignancies combined. Although it is rare to metastasize, patients with multiple or frequently recurring BCC can suffer substantial comorbidity and be difficult to manage. Assessment of risk is a key element of management needed to inform treatment selection. The overall management of BCC primarily consists of surgical approaches, with radiation therapy as an alternate or adjuvant option. Many superficial therapies for BCC have been explored and continue to be developed, including topicals, cryosurgery, and photodynamic therapy. Two hedgehog pathway inhibitors were recently approved by the FDA for systemic treatment of advanced and metastatic BCC, and others are in development. The NCCN Guidelines for Basal Cell Skin Cancer, published in full herein, include recommendations for selecting among the various surgical approaches based on patient-, lesion-, and disease-specific factors, as well as guidance on when to use radiation therapy, superficial therapies, and hedgehog pathway inhibitors.

    Our knowledge of renal cell carcinoma (RCC) is rapidly expanding. For those who diagnose and treat RCC, it is important to understand the new developments. In recent years, many new renal tumors have been described and defined, and our understanding of the biology and clinical correlates of these tumors is changing. Evolving concepts in Xp11 translocation carcinoma, mucinous tubular and spindle cell carcinoma, multilocular cystic clear cell RCC, and carcinoma associated with neuroblastoma are addressed within this review. Tubulocystic carcinoma, thyroid-like follicular carcinoma of kidney, acquired cystic disease-associated RCC, and clear cell papillary RCC are also described. Finally, candidate entities, including RCC with t(6;11) translocation, hybrid oncocytoma/chromophobe RCC, hereditary leiomyomatosis and RCC syndrome, and renal angiomyoadenomatous tumor are reviewed. Knowledge of these new entities is important for diagnosis, treatment and subsequent prognosis. This review provides a targeted summary of new developments in RCC. PMID:24364021

    Full Text Available We previously published our and Johns Hopkins data titled: "Platinum-based therapy in adenosquamous pancreatic cancer: experience at two institutions” [1]. We will here like to submit a related case report as a letter to the editor to JOP in reference to the above paper. Squamous cell carcinoma of the pancreas has various reported incidence rates, ranging from 0.5% to as high as 5% of pancreatic ductal carcinomas [2, 3]. Of the 1300 cases of pancreatic cancers observed at autopsy in a survey in Japan in 1992, 0.7% were squamous cell carcinoma [4]. A Mayo clinic review of very rare exocrine tumors showed an even rarer incidence of squamous cell carcinoma when compared to acinar and small cell carcinoma of the pancreas [5]. This discrepancy in the reported incidence rates related to the fact that some of the cases represent adenosquamous carcinoma rather than pure squamous cell carcinoma of pancreas. In an analysis of 25 patients, mean age at diagnosis of pancreatic squamous cell carcinoma was 62 years (range: 33–80 years and there was no gender difference [6]. There is no study about the molecular profile of squamous carcinoma of the pancreas. There are no retrospective or prospective studies about the best therapy for these tumors

  11. Oxidative stress and counteracting mechanisms in hormone receptor positive, triple-negative and basal-like breast carcinomas

    International Nuclear Information System (INIS)

    Triple-negative breast cancer (TNBC) and basal-like breast cancer (BLBC) are breast cancer subtypes with an especially poor prognosis. 8-Hydroxydeoxyguanosine (8-OHdG) is a widely used marker of oxidative stress and the redox-state-regulating enzymes peroxiredoxins (PRDXs) are efficient at depressing excessive reactive oxygen species. NF-E2-related factor 2 (Nrf2) and Kelch-like ECH-associated protein 1 (Keap1) are redox-sensitive transcription factors that regulate PRDX expression. This is the first study to assess oxidative stress and or cell redox state-regulating enzymes in TNBC and BLBC. We assessed immunohistochemical expression of 8-OHdG, Nrf2, Keap1, PRDX III and PRDX IV in 79 women with invasive ductal breast carcinomas. Of these tumors, 37 represented TNBC (grade II-III tumors with total lack of ER, PR and human epidermal growth factor receptor 2 [HER2] expression). Control cases (n = 42) were ER-positive, PR-positive and HER2-negative. Of the 37 TNBCs, 31 had BLBC phenotype (TNBC with expression of cytokeratin 5/6 or epidermal growth factor receptor 1). Patients with TNBC had worse breast cancer-specific survival (BCSS) than the control group (p = 0.015). Expression of 8-OHdG was significantly lower in TNBC than in the non-TNBC group (p < 0.005). 8-OHdG immunostaining was associated with better BCSS (p = 0.01), small tumor size (p < 0.0001) and low grade (p < 0.0005). Keap1 overexpression was observed in the TNBC cohort (p = 0.001) and Keap1-positive patients had worse BCSS than Keap1-negative women (p = 0.014). PRDX IV was overexpressed in the TNBC vs. the non-TNBC group (p = 0.022). Cellular redox state markers may be promising targets when elucidating the pathogenesis of TNBC

    2010-11-01

    Full Text Available Abstract Background Basal-like carcinoma are aggressive breast cancers that frequently carry p53 inactivating mutations, lack estrogen receptor-α (ERα and express the cancer stem cell markers CD133 and CD44. These tumors also over-express Interleukin 6 (IL-6, a pro-inflammatory cytokine that stimulates the growth of breast cancer stem/progenitor cells. Results Here we show that p53 deficiency in breast cancer cells induces a loss of methylation at IL-6 proximal promoter region, which is maintained by an IL-6 autocrine loop. IL-6 also elicits the loss of methylation at the CD133 promoter region 1 and of CD44 proximal promoter, enhancing CD133 and CD44 gene transcription. In parallel, IL-6 induces the methylation of estrogen receptor (ERα promoter and the loss of ERα mRNA expression. Finally, IL-6 induces the methylation of IL-6 distal promoter and of CD133 promoter region 2, which harbour putative repressor regions. Conclusion We conclude that IL-6, whose methylation-dependent autocrine loop is triggered by the inactivation of p53, induces an epigenetic reprogramming that drives breast carcinoma cells towards a basal-like/stem cell-like gene expression profile.

    T regulatory cells (Tregs) are a lineage of lymphocytes involved in immune response suppression that are characterized by the expression of the forkhead box P3 (FOXP3) transcription factor. Notch pathway regulates FOXP3 transcription in Tregs, but its role in breast cancer is unknown. We aimed at studying whether Notch pathway regulates FOXP3 expression and Tregs content in breast cancer, and its association with luminal breast carcinomas. We analyzed by quantitative Real-Time PCR the mRNA levels of FOXP3, Notch pathway genes (Notch1, Notch2, Notch4 and Jagged1) and STAT3 in a series of 152 breast carcinomas including hormone receptor-positive and -negative phenotypes (luminal and Triple Negative/Basal-like). We also studied the protein expression of Notch1, STAT3 and FOXP3 by immunohistochemistry. High FOXP3 mRNA levels correlated with larger tumor size (p=0.010), histological grade 3 (p=0.008) and positive lymph-node status (p=0.031). Also, low levels of Notch pathway genes mRNA correlated with poor prognostic factors such as larger tumor size, positive lymph-node status, tumor phenotype and infiltrating tumor Tregs. A survival analysis for the patients showed that large tumor size, histological grade 3, vascular invasion, infiltrating Tregs and low Notch1 mRNA expression were significantly associated with a decreased patients' overall survival (p≤0.05). On a multivariate analysis, high Tregs content (HR=3.00, 95% CI 1.04-8.90, p=0.042) and low Notch1 mRNA levels (HR=3.33, 95% CI 1.02-10.86, p=0.046) were independent markers for overall survival. Our results support that the Notch pathway up-regulation promotes luminal breast carcinomas, whereas down-regulation correlates with the expression of FOXP3, favors tumor Tregs infiltration and associates with Triple Negative/Basal-like tumors.

    2011-01-01

    Full Text Available Introduction. Prostatic gland basal cell proliferations exhibit morphological continuum ranging from basal cell hyperplasia to basal cell carcinoma. In the following report, we described clinical features, morphological spectrum, neuroendocrine differentiation and histogenesis of prostatic gland basal cell carcinoma in our patient. Case report. Hematoxylineosin (HE, Alcian blu-periodic acid schiff (ABPAS at pH 2.5 stained sections and the avidin-biotinperoxidase complex (ABC, were performed on prostate gland paraffin-embedded tissue. Monoclonal antibodies directed against cytokeratin (34βE12 which selectively stains basal cells, prostate specific antigen (PSA, chromogranine A, neuron-specific enolase (NSE, synaptophysin and CD56, were used. Basal cell proliferations exhibited a morphological continuum ranging from basal cell hyperplasia to prostatic gland carcinoma. In these prostatic lesions, positive reactivity was demonstrated for 34βE12 and CD56. These findings indicate that the basaloid cells of basal cell hyperplasia, florid basal cell hyperplasia, atypical basal cell hyperplasia and basal cell carcinoma are derived from basal cells of the normal prostate gland suggesting a continuum in the progression of hyperplasia to benign and then malignant neoplasia. The presence of CD56 protein in the discovered lesions may be related to their neuroendocrine differentiation. Conclusion. The fact, that our patient was well six years after the radical prostatectomy supports the belief of some authors that basal cell carcinoma represents a low grade carcinoma with an excellent prognosis.

  6. Learning semantic histopathological representation for basal cell carcinoma classification

    2013-03-01

    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%.

Methods Cultured A431 cells were exposed to 0.05—50.0 μmol/L methylarsonous acid (MMAⅢ), 0.05-200.0 μmol/L arsenic trioxide (As2O3,As3+) , 0.5-500.0 μmol/L disodium hydrogen arsenate(As5+) or sodium dimethylarsonate(DMAⅤ) for 24 h, respectively. MTT assay were used to evaluate the cell viability, the malondialdehyde (MDA) content and the activity of the superoxide dismutase (SOU) in HaCaT were detected respectively. The intracellular reactive oxygen species (ROS) were detected with flow cytometry and the atomic fluorescence were used to analyze intracellular or extracellular levels of different speciations of arsenic. Results When the dose was in a certain range, MMAⅢ (≥0.5μmol/L), As2O3 (≥200.0 μmol/L), disodium hydrogen arsenate (0.5, ≥200.0 μmol/L)and sodium dimethylarsonate (500.0 μmoL/L) could all decrease the cell viability (P50.0 μmol/L As2O3> 100.0 μmol/L disodium hydrogen arsenate > 100.0 μmol/L sodium dimethylarsonate. As for As2O3 and disodium hydrogen arsenate, the methylation ratios in low—dose groups were higher than the high—dose ones' , and the ratios in As2O3 groups was higher than those in As5+ groups. Conclusion Arsenides may inhibit A431 cells proliferation in higher exposure levels and promote proliferation in lower exposure levels, the mechanism probably relates to oxidative stress and arsenic metabolism in A431 cells induced by different speciations of arsenide with various concentrations.%目的 探讨不同砷化合物致人表皮癌细胞(A431)的细胞毒性及氧化应激和砷代谢的情况.方法 培养的A431细胞分别暴露于0.05~50.0 μmol/L一甲基亚胂酸(MMAⅢ),0.05~200.0 μmol/L三氧化二砷(As2O3,As3+),0.5~500.0μmol/L砷酸氢二纳(As5+)和二甲基胂酸钠(DMAV)24 h,应用四甲基偶氮唑盐(MTT)法测定细

    In Western countries, breast cancer is the most common cancer in women, whereas metastases to the breast from extramammary malignancies are extremely rare. We present the case of a 60-year-old woman, who underwent surgery in 2007 for clear cell renal cell carcinoma and who 4 years later presented with a breast metastasis from clear cell renal cell carcinoma.

    Hyalinizing clear cell carcinoma (HCCC) is an uncommon malignant salivary gland tumor accounting for about 1% of all intra-oral salivary gland tumors. Microscopic diagnosis of clear cell carcinoma may be challenging because of the spectrum of features which frequently overlaps with the other salivary gland tumors that contain clear cells, and thus it may be a diagnosis of exclusion. Here we, report a case of HCCC in a 36 years old female with detailed histological, histochemical and immunohis...

    Primary small cell carcinoma of the urinary bladder is very rare; only several studies have been reported in the English literature. A 62-year-old woman was admitted to our hospital because of hematuria and dysuria. Bladder endoscopy revealed a large polypoid tumor at the bladder base. Transurethral bladder tumorectomy (TUR-BT) was performed. Many TUR-BT specimens were obtained. Histologically, the bladder tumor was pure small cell carcinoma. Immunohistochemically, the tumor cells were positi...

    Full Text Available An uncircumcised 65 year male, with history of phimosis presented with retention of urine and ulceration and bleeding in the prepuce. Circumcision was done under local anesthesia which revealed an ulcero-proliferative growth involving the prepuce and glans. The prepucial skin was sent for histopathological examination. The diagnosis was histopathologically confirmed as Acantholytic Squamous Cell Carcinoma. Acantholytic squamous cell carcinoma is a highly malignant, unusual variant of squamous cell carcinoma invading deeper anatomic structures and is associated with a higher incidence of regional metastasis and mortality.

    Full Text Available Small Cell Carcinoma of the bladder accounts for less than 1% of all bladder tumors. Small Cell Carcinoma of the bladder has an aggressive behaviour and is usually metastatic at diagnosis. Due to its infrequent occurence, the literature on this entity is limited; which unsurprisingly leads to an uncertanity in defining an ideal therapeutic approach. This report, overviews the literature while describing a 70- year- old female patient who is diagnosed with small cell carcinoma of the bladder arising in an unusual localization.

  16. Small cell carcinoma of the urinary bladder

    International Nuclear Information System (INIS)

    Small cell carcinoma of the urinary bladder (SCCUB) is an extremely rare tumor that exhibits aggressive behavior and accounts for approximately less than 1% of all primary bladder tumors. Small cell carcinoma generally occurs in the lung, accounting for 25% of all pulmonary malignancies. SCCUB exhibits a similar microscopic and immunohistochemical appearance to that of small cell carcinoma of the lung. There is no consensus about the standard therapy, owing to its rarity. Surgical resection seems to be the mainstay of treatment for patients with limited stage, together with neoadjuvant or adjuvant platinum-based chemotherapy. Radiation therapy has same small effect for palliative purposes, as well as being an alternative to radical cystectomy. Patients with advanced stage, although given platinum-based chemotherapy, have a poor prognosis. We herein review epidemiology, clinical presentation, diagnosis, pathological features, and current management of small cell carcinoma of the urinary bladder. (author)

    Squamous cell carcinoma arising in an odontogenic cyst is uncommon. The diagnosis of carcinoma arising in a cyst requires that there must be an area of microscopic transition from the benign epithelial cyst lining to the invasive squamous cell carcinoma. We report a histopathologically proven case of squamous cell carcinoma arising in a residual mandibular cyst in a 54-year-old woman.
