Lesson It is rare for renal cell carcinoma to involve the peritoneum and cause malignant ascites. Furthermore, it is uncommon for malignant ascites to be a presenting feature of this cancer. An unusual case of renal cell carcinoma presenting with malignant ascites is reported, and its response to sunitinib described.
Most common malignant tumour of the kidney is Renal Cell Carcinoma (RCC) and is known for its unpredictable clinical behaviour. Aetiology and risk factors are not completely understood. Extensive workup is being done in the understanding of the disease, especially to diagnose early and to treat promptly. The objective of this study was to determine the clinical presentation and pathological pattern of RCC. Methods: After approval from ethical committee a retrospective review of records was conducted extending from January 2012 to January 2014 to identify clinical characteristics of renal cell carcinomas. The study included all renal cancer patients presented to Sheikh Zayed Hospital Lahore with in this specified period. The data was retrieved regarding, history, physical examination and necessary investigations such as ultrasonography of abdomen and pelvis and CT scan of abdomen and pelvis. Results: There were total of 50 cases. The male to female ratio was 3:2. Mean age of patients were 52.38 (18-93) years old. Most common clinical presentation was gross haematuria(66%).The mean tumour size was 8.34 (3-24) cm. Tumour histology were clear cell (84%), papillary transitional cell carcinoma (12%) and oncosytoma contributed 4%. Conclusion: We observed that large number of the patients with RCC presented with haematuria and most of them were male. Common pathological type was clear cell carcinoma. (author)
Full Text Available Renal clear cell carcinoma (RCC has different manifestations, including uncommon metastasis and paraneoplastic syndromes. Here we report a rare case of RCC presenting as metastasis to the mandible. A 57-year-old patient with mandibular swelling was referred to the dentist. After necessary evaluations, an incisional biopsy of mandible showed metastatic RCC. The patient was referred to the urologist. The patient underwent right radical nephrectomy. Pathological examination showed clear renal cell carcinoma. Every abnormal bone lesion in the oral cavity should be evaluated carefully and the possibility of a malignant lesion should always be considered.

Renal cell carcinoma rarely presents with typical features of abdominal pain, flank mass and haematuria, and up to 30% of patients present with metastases. We present the case of an 81 year old man who presented with a painless, pulsatile sternal metastasis as an initial presentation of renal cell carcinoma. This case highlights the importance of recognizing even unusual presentations of renal cell carcinoma, and that although sternal metastases are rare, when they do occur there should be a ...
Full Text Available Renal cell carcinoma is one of the most common tumours after lung and breast cancer to metastasize to the head and neck. Initial presentation by tongue metastasis is extremely rare. A 67-year-oldmale presented with a 4.8 cm mass on his tongue. The result of the punch biopsy from the tongue was diagnosed as a clear cell variant of squamous cell carcinoma. The biopsy was reevaluated due to the renal mass found during the check-up and the rapid enlargement of the mass. The excision of the tongue mass and the radical nephrectomy material confirmed the diagnosis of a metastatic renal cell carcinoma in the tongue and renal cell carcinoma in the kidney. Since metastasis of renal cell carcinoma to the tongue is uncommon it may cause difficulties in diagnosis and proper management. The metastasis of renal cell carcinoma should always be considered in the differential diagnosis among the clear cell neoplasms.

Full Text Available Malignancy in pregnancy is rare. Carcinomas in pregnancy are mostly kidney cell mass. Renal cell carcinoma (RCC is the commonest malignancy in pregnancy. Because of softness and increased vascularity, rupture of renal cell carcinoma is not uncommon. Here we are presenting a rare case of renal cell carcinoma in pregnancy with spontaneous rupture resulting in massive hemoperitoneum and serious outcome because of late presentation renal cell carcinoma seldom ruptures. A 26 year old woman G2P1L1 with term pregnancy was referred to hospital 80kms away from periphery with non-progression of labour. There was antenatal record suggesting hypertensive disorder of pregnancy in second trimester. On examination, patient was in hypovolemic shock with profuse distension of abdomen. Diagnosis of abruption grade 3 or rupture uterus was made and immediate laparotomy was done. On opening the abdomen, there was hemoperitoneum but uterus was intact. Emergency LSCS done extracted a stillborn baby. There were no retro placental clots also. There was lot of necrotic tissue in the abdomen and there was a tumour arising from lower pole of left kidney which had invaded the renal vessels and had ruptured. Peripartum hysterectomy and left nephrectomy was done. Women did not respond to treatment and died. The objective of presenting this case is the dilemmas faced by the obstetrician in case of shock in 2nd stage of labour. Simple diagnostic tool like renal ultrasound will help to detect at an early stage which could improve the outcome. All cases of hypertensive disorders of pregnancy should be investigated for secondary causes of hypertension. Abdominal USG must be done for all cases of hypertensive disorders of pregnancy in 2nd trimester. Prompt diagnosis and early treatment is the key in management of such condition in pregnancy.

Full Text Available Large cell neuroendocrine tumor of the urinary bladder is very rare. It is a type of neuroendocrine carcinoma that is morphologically different from small cell carcinoma.This manuscript describes a 67-year-old man who presented with hematuria. Ultrasonogrophic and computer tomography revealed a 5 cm mass in right posterolateral wall of the bladder that invaded perivesical tissue and he subsequently underwent transurethral resection. Microscopic examination showed a tumor with a sheet-like and trabecular growth pattern comprising necrotic areas which infiltrated the muscularis propria. Tumoral cells had coarse chromatin, prominent nucleoli, moderate amount of cytoplasm and immunohistochemically stained strongly positive with synaptophysin, chromogranin and CD56.There are only few case reports of large cell neuroendocrine tumor of the urinary bladder so the biological behavior and the treatment protocol of these tumors are still obscure. Appropriate management protocols and prognostic estimation could be achived by the increased number of cases being reported. Therefore in a case of a poorly differentiated tumor in bladder, although rare, it is important to consider large cell neuroendocrine carcinoma in differential diagnosis.

Full Text Available Lung cancer is the leading cause of death among malignant tumors. Pulmonary neuroendocrine tumors encompass a broad spectrum of tumors including the large-cell neuroendocrine carcinoma. The case of a 57-year-old white housewife with a history of smoking, diabetes, hypothyroidism and hypertension who sought medical attention because of headache, vomiting, weight loss, neuropsychiatric symptoms and metastatic inguinal lymphadenopathy is presented. The symptoms resulted from the extrapulmonary metastases found. Imaging studies, histology and immunohistochemistry confirmed the diagnosis of large-cell carcinoma of the lung with neuroendocrine pattern. This type of highly aggressive tumor is usually diagnosed when there are already multiple metastases, which affects the short-term prognosis. The aim of this paper is to inform the medical community of this case due to the scarce reports in the literature.

Abstract Renal cell carcinoma is a potentially lethal cancer with aggressive behavior and a propensity for metastatic spread. Due to the fact that the patterns of metastases from renal cell carcinomas are not clearly defined, there have been several reports of cases of renal cell carcinoma associated with rare metastatic sites and atypical presenting symptoms. The present review focuses on these atypical rare clinical presentations of renal cell carcinomas both at the time of diagnosis of the...

Full Text Available Abstract Background Primary squamous cell carcinomas of the colorectum are very uncommon. Until now, to the best of our knowledge, only 114 cases of squamous cell carcinoma in the colorectum exist in the reported literature. Here we report a case of squamous cell carcinoma of the rectum in the ethnic Kashmiri population in northern India. Case Presentation The case of a 60-year-old male patient (Asian with a pure squamous cell carcinoma of the rectum is presented here. The patient underwent a curative surgery with concomitant chemotherapy. Two years after the initial curative resection of the tumor he is still alive. Conclusion The prognosis for squamous cell carcinoma of the colorectum is worse than for that of adenocarcinoma, because of the delayed diagnosis. The etiopathogenicity of squamous cell carcinoma of the colorectum is discussed. Surgical resection of the lesion seems to be the treatment of choice. Chemotherapy also helps in improvement of the prognosis.

Full Text Available Introduction: Metastatic lesions of the oral cavity are extremely rare, accounting for approximately 1% of all malignant oral tumors. The most common primary sources of metastatic tumors in the oral region are, from the most to the least common, the breast, lung, kidney, bone, and colon. Renal cell carcinoma accounts for nearly 3% of all adult malignancies. It usually metastasizes to the lungs, bone, adrenal glands, and regional lymph nodes. The incidence of metastasis from renal cell carcinoma to the head and neck region is very low. The tongue is considered a very rare atypical ear, nose, and throat (ENT location for metastasis of renal cell carcinoma. The present case from Iran reports tongue metastasis of renal cell carcinoma (RCC. Case Report: The following report is based on an 80-year old male patient with a tongue lesion and ambiguous past medical history that ultimately leads to diagnosis of a metastatic RCC. We also updated a previous literature review that was published 2008. A histopathological differential diagnosis for clear-cell tumors is also discussed. Conclusion: Because of the rarity of metastatic tumors of the oral region as well as the presence of other lesions with clear cells, diagnosis of metastatic clear-cell RCC in the oral cavity can be very difficult and challenging.
Until the turn of the millennium, metastatic renal cell carcinoma (mRCC) was regarded as one of the most refractory cancers; highly resistant to both radiation and systemic therapy, and only small group of patients responded to immune modulation. Involved targeted therapies, which influence specific signal transduction pathways of tumor formation and progression, opened new options of treatment to give patients a new hope. After the first experiences with the new biologic agents we can claim, that these patients have improved a quality of life, provided stabilization of disease and prolong life of patients, but the cure is not available. However, there are so many studies with target therapies in RCC, but the most correct algorithm of treatment does not exist. Targeted therapies rarely achieve remission, prevailing a stabilisation of disease so patients have to undergo chronic treatment. In choice of optimal treatment is necessary to regard for quality of life, so usually the winner is the drug with the lowest toxic potential. (author)

Fibroepithelioma of Pinkus and nodular basal cell carcinoma (BCC) are different morphological variants of BCC. It is very rare to see both the variants together in a single lesion. Here we report a case of a 56-year-old female who presented with a nodule on the trunk, which on biopsy showed features of both nodular BCC and fibroepithelioma of Pinkus. PMID:27559504
Full Text Available Introduction. Rectal large cell neuroendocrine carcinoma (LCNEC is a poorly differentiated neoplasm that is very rare and belongs within the poorest prognostic subgroup among primary colorectal neoplasms. Here, we describe a case of LCNEC of the rectum, which highlights the aggressive clinical course and poor prognosis associated with this disease. Case Presentation. We report a case of a 63-year-old male who presented to our hospital with a one-month history of lower abdominal pain, constipation, and weight loss. A computed tomography (CT scan of the chest, abdomen, and pelvis revealed a rectal mass as well as metastatic disease of the liver and lung. Flexible sigmoidoscopy revealed a fungating, ulcerated and partially obstructing rectal mass located 6 cm from the anal verge. This mass was biopsied and pathological examination of the resected specimen revealed features consistent with a large cell neuroendocrine carcinoma. Conclusion. Rectal large cell neuroendocrine carcinomas are rare and have a significantly worse prognosis than adenocarcinomas. At diagnosis, a higher stage and metastatic disease are likely to be found. It is important to differentiate large cell, poorly differentiated neuroendocrine carcinomas from adenocarcinomas of the colon and rectum pathologically because patients may benefit from alternative cytotoxic chemotherapeutic regimens.

Head and neck tumours presenting as a neck abscess are extremely rare. Two patients with laryngeal squamous cell carcinoma, presenting with a prelaryngeal abscess, are described. Although clinically and on the CT studies these cases were suspect for underlying malignancy, the initial biopsies were negative for cancer. Because of persistent suspicion, repeat biopsies finally confirmed the presence of a squamous cell carcinoma. Pathological examination after total laryngectomy showed cancer localised in one of the true vocal cords, invading the anterior commissure and thyroid cartilage. However, the prelaryngeal soft tissues were free of tumour, showing only inflammatory changes and collections of pus. These cases emphasize the importance of repeat targeted biopsies and follow-up CT-studies in patients with a prelaryngeal abscess of obscure aetiology, in order to exclude or confirm a possible underlying malignancy.

Renal cell carcinomas (RCCs) are neoplasias with high prevalence and mortality. We previously reported that several peptidases may be involved in the pathophysiology of clear cell renal cell carcinoma (CCRCC). Now, to gain insight into the reasons that lead the various RCC types to behave very differently with regard to aggressiveness and response to anticancer treatments, we analyzed subsets of chromophobe renal cell carcinoma (ChRCC), and renal oncocytoma (RO), a benign tumor; as well as different grades and stages of CCRCCs. Particulate APN, APB, and APA activities were decreased in both ChRCC and RO (tumor vs. nontumor tissues). Interestingly, activities were downregulated in a tumor-type specific way and the intensities of the decreases were stronger in the benign tumor than in the malignant type. Moreover, when two key histopathological parameters for tumor prognosis (high vs. low stage and grade) were analyzed, increases of activity were also observed in several of these cell surface peptidases (APN, APB). Some soluble activities (APB, Asp-AP) were also downregulated in the RCCs. With respect to genetic expression, PSA and APN were in a positive correlation related to their activities in both ChRCC and RO; but not APB, Asp-AP, APA, and PGI. These results may suggest an involvement of several peptidases in the pathophysiology of renal cancer, since they presented different patterns of activity and expression in tumors with different behaviors.

Tumors commonly harbor multiple genetic alterations, some of which initiate tumorigenesis. Among these, some tumor-specific somatic mutations resulting in mutated protein have the potential to induce antitumor immune responses. To examine the relevance of the latter to immune responses in the tumor and to patient outcomes, we used datasets of whole-exome and RNA sequencing from 97 clear cell renal cell carcinoma (ccRCC) patients to identify neoepitopes predicted to be presented by each patient's autologous HLA molecules. We found that the number of nonsilent or missense mutations did not correlate with patient prognosis. However, combining the number of HLA-restricted neoepitopes with the cell surface expression of HLA or β2-microglobulin(β2M) revealed that an A-neo(hi)/HLA-A(hi) or ABC-neo(hi)/β2M(hi) phenotype correlated with better clinical outcomes. Higher expression of immune-related genes from CD8 T cells and their effector molecules [CD8A, perforin (PRF1) and granzyme A (GZMA)], however, did not correlate with prognosis. This may have been due to the observed correlation of these genes with the expression of other genes that were associated with immunosuppression in the tumor microenvironment (CTLA-4, PD-1, LAG-3, PD-L1, PD-L2, IDO1, and IL10). This suggested that abundant neoepitopes associated with greater antitumor effector immune responses were counterbalanced by a strongly immunosuppressive microenvironment. Therefore, immunosuppressive molecules should be considered high-priority targets for modulating immune responses in patients with ccRCC. Blockade of these molecular pathways could be combined with immunotherapies targeting neoantigens to achieve synergistic antitumor activity. Cancer Immunol Res; 4(5); 463-71. ©2016 AACR.

Miliary mottling on chest radiography is seen in miliary tuberculosis, certain fungal infections, sarcoidosis, coal miner's pneumoconiosis, silicosis, hemosiderosis, fibrosing alveolitis, acute extrinsic allergic alveolitis, pulmonary eosinophilic syndrome, pulmonary alveolar proteinosis, and rarely in hematogenous metastases from the primary cancers of the thyroid, kidney, trophoblasts, and some sarcomas. Although very infrequent, miliary mottling can be seen in primary lung cancers. Herein, we report the case of a 28-year-old female with chest X-ray showing miliary mottling. Thoracic computed tomography (CT) features were suggestive of tuberculoma with miliary tuberculosis. CT-guided fine needle aspiration cytology confirmed the diagnosis as lower-lobe, left lung non-small cell carcinoma (adenocarcinoma). It is rare for the non-small cell carcinoma of the lung to present as miliary mottling. The rarity of our case lies in the fact that a young, non-smoking female with miliary mottling was diagnosed with non-small cell carcinoma of the lung. PMID:23645961

Here, we present a case of RCC with EBM, in which the primary tumor was detected after the detection of secondary. A 60-year-old man presented with cough for last 2 months. Contrast enhanced computed tomography (CECT chest followed by bronchoscopy revealed an endobronchial mass at left bronhi. CECT whole abdomen revealed a left-sided renal space occupying lesion (SOL. CT guided fine needle aspiration cytology of the SOL proved it as a RCC. Palliative bronchoscopic removal of endobronchial mass by snaring diathermy was done.

Full Text Available "nIntroduction: Squamous cell carcinoma (SCC of the head and neck is usually confined to local and regional sites but occasionally patients may present with rare manifestation of distant metastasis. We reported a case of hypopharyngeal SCC with liver and peritoneal metastasis. "nClinical picture: A 50-year-old female with advanced hypopharyngeal SCC was treated in this center by laryngoesophagectomy and gastric pull up. "nOne year later she presented with signs of bowel obstruction. CT scan showed an 11×15 centimeter mass with a large necrotic center in the peritoneal cavity which caused bowel obstruction. "n Some other necrotic masses were seen in the liver too. After surgery, histopathologic examination shows these masses are metastatic SCC. Abdominal fluid showed malignant cells. "nConclusion: These rare and aggressive presentations of SCC of the head and neck remind us that they may show atypical manifestations and may need more aggressive search of the distant disease in at least some subgroups of the head and neck carcinoma.

Full Text Available Abstract Lymph node metastasis from cutaneous squamous cell carcinoma is uncommon. The popliteal fossa is rarely involved with metastasis. Popliteal lymph node dissection is uncommonly performed and not frequently discussed in the literature. We present a case of squamous cell carcinoma of the heel with popliteal and inguinal metastasis. This is followed by a description of the relevant anatomy of the popliteal fossa and the technique of popliteal lymphadenectomy.

Cytokeratin-positive interstitial reticulum cell (CIRC) sarcoma is a rare type of dendritic cell tumor derived from a subset of fibroblastic reticular cells. Expression of cytokeratins and extranodal location of these tumors can lead to a misdiagnosis of carcinoma. We report two cases of CIRC sarcomas primarily involving the scalp and breast. Patients were referred with an initial diagnosis of carcinoma. Case 1 underwent wide local excision of the scalp tumor with left posterolateral neck dissection. Case 2 had modified radical mastectomy for the tumor in left breast. Histopathological examination of both specimens showed an epithelioid to spindle cell malignant tumor that co-expressed CK 8, CK 18, vimentin, and smooth muscle actin. A diagnosis of CIRC sarcoma was made. Pathologists should be aware of this subset of dendritic cell sarcoma. Carcinomas, other sarcomas of the accessory dendritic cell family, and poorly differentiated malignant tumors have to be ruled out by combination of morphology, immunohistochemistry, and electron microscopic studies.

Full Text Available Background & objectives: Clinical spectrum of most of the diseases in developing countries is different from the west. Similarly whether renal cell carcinomas (RCC in a developing country like India is seen in the same spectrum in relation to the age at presentation as in the west is not described in the literature. This study was carried out to investigate the spectrum of RCC in India with regards to age of onset, stage at presentation and survival. Methods: Patients with renal tumour, treated between January 2000 to December 2012 in a tertiary care hospital in north India, were analyzed for age at presentation, clinical features and histopathological characteristics. Clinical diagnosis was made by contrast enhanced computerized tomography (CECT scans and/or magnetic resonance imaging (MRI. Renal masses diagnosed as angiomyolipoma, infective masses and hydatid cysts were excluded from the analysis. Impact of various age groups on gender, tumour size, TNM stage, Fuhrman grade, histopathological subtypes, lymph node, inferior vena cava (IVC involvement and survival was analyzed. Patients were grouped in five age groups i.e. ≤39, 40-49, 50-59, 60-69 and more than 70 yr of age. Results: Of the total 617 patients with 617 renal tumours (2 patients had bilateral tumours but only the larger tumour was considered clinically suspected as RCC, 586 had epithelial cell tumour and the remaining 31 had non epithelial cell tumour. The mean tumour size was 8.08±3.5 cm (median 7, range 1-25 cm. Tumour of less than 4 cm size was present in only 10.4 per cent patients. The mean age at diagnosis was 55.15±13.34 (median 56, range 14-91 yr years. A total of 30.03 per cent of renal tumours presented in patients younger than 50 yr of age. Though there was no difference in stage, Fuhrman′s grade, IVC involvement and lymph nodal spread among various age groups, younger patients had higher proportion of non clear cell RCC and only 48.59 per cent of them presented

Head neck squamous cell carcinoma (HNSCC) is a common kind of malignancies in human body. For HNSCC in early stage, either surgical operation or radiotherapy can acquire satisfactory treatment results. However, any single treatment modality such as surgery alone or single radiation is insufficient to gain satisfactory tumor control. Multidisciplinary treatment (MDT) has become a mainstay and important therapeutic strategy in the management of HNSCC. Among various approaches in the MDT, concurrent chemoradiotheraqpy (CCR) constitutes a major progress, which implicates a lot in improving outcomes and organ preservations in managing HNSCC. In the present review, the history, mechanisms, indications along with side effects and drawbacks, and perspectives of CCR are to be described and discussed, in the hope of providing effective guidance for the domestic MDT, especially CCR in the management of HNSCC.

Background Renal cell carcinoma is well known for its frequency to metastasise, particularly to lungs, liver, bones and brain. Metastasis to the skin is much less common. Presentation as a result of the skin lesion is even more unusual, with only 14 previously reported cases in the English literature. The majority of these cases have been reported in patients with recurrent disease or with other metastases. Case presentation We present only the second case of non-recurrent renal cell carcinom...

Merkel cell carcinoma (MCC) is a rare malignant cutaneous neuroendocrine tumour with an aggressive behaviour and frequent regional lymph node and distant metastases. It mostly occurs in old patients and the commonest sites are the skin of the head, neck and the extremities. Typically, the primary tumour presents as a fast-growing, painless, reddish nodule with an iceberg-like effect, broadening in the depth. Although the pathogenesis of MCC remains largely unknown, ultraviolet radiation and immunosuppression are likely to play a significant pathogenetic role. The authors describe an unusual case of MCC clinically presenting as lymphedema on the right leg due to an inguinal lymphonodal metastasis. Although extensive investigations were performed the authors were unable to discover the cutaneous primary tumor. The authors examine the etiopathogenesis and hypothesis of this rare tumour and describe the clinical differential diagnosis. They suggest that clinical features together with imaging studies and morphological and immuno-histochemical findings are important for the correct diagnosis. PMID:18497730

Primary clear cell carcinoma of the vagina or uterine cervix is a very rare tumor. We report radiologic findings of two cases of clear cell carcinoma, arising in the vagina and uterine cervix in a 16-year-old and a 26-year-old female. These were presented as a large polypoid mass with a stalk and expanding the vaginal fornix. One case with ultrasonography showed relatively homogeneous echoic solid mass; the other case with a CT showed heterogeneously and strongly enhancing mass. All of the two cases showed non-specific signal intensity with heterogeneous and strong enhancement on MRI.

The small bowel rarely suffers from metastatic tumors from outside the abdomen. Small bowel obstructions caused by the metastatic spread of squamous cell carcinoma (SCC) of the hand to the intestines are even rarer. A 71-year-old man with intermittent abdominal distension and pain for 4 months was diagnosed with partial bowel obstruction. The patient underwent a video capsule endoscopic examination; however, the patient was unable to pass the capsule, which worsened the abdominal distension. ...

Conclusion: With initial unsuccessful treatment, his lesion was excised and pathological evaluation reported Merkel Cell Carcinoma (MCC. Despite further surgical excision and adjuvant chemotherapy, increased hyper metabolism was found in the left descending colon and left prostate of unknown etiology. There have been reports of metastasis of primary MCC to the small bowel mesentery; therefore new focal hyper metabolism cannot be delineated precisely as unrelated to MCC until biopsy and histochemical staining are performed.

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...

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 dend...

Purpose: Penile squamous cell carcinoma (SCC) is a rare entity, with few published series on outcomes. We evaluated the stage distributions and outcomes for surgery and radiation therapy in a U.S. population database. Methods and Materials: Subjects with SCC of the penis were identified using the National Cancer Institute Surveillance, Epidemiology and End Results (SEER) Program database between 1988 and 2006. Descriptive statistics were performed, and cause-specific survival (CSS) was estimated using Kaplan-Meier analysis. Comparisons of treatment modalities were analyzed using multivariate Cox regression. Subjects were staged using American Joint Committee on Cancer, sixth edition, criteria. Results: There were 2458 subjects identified. The median age was 66.8 years (range, 17-102 years). Grade 2 disease was present in 94.5% of cases. T1, T2, T3, T4, and Tx disease was present in 64.8%, 17.1%, 9.5%, 2.1%, and 6.5% of cases, respectively. N0, N1, N2, N3, and Nx disease was noted in 61.6%, 6.9%, 4.0%, 3.7%, and 23.8% of cases, respectively. M1 disease was noted in 2.5% of subjects. Individuals of white ethnicity accounted for 85.1% of cases. Lymphadenectomy was performed in 16.7% of cases. The CSS for all patients at 5 and 10 years was 80.8% and 78.6%. By multivariable analysis grades 2 and 3 disease, T3 stage, and positive lymph nodes were adverse prognostic factors for CSS. Conclusion: SCC of the penis often presents as early-stage T1, N0, M0, grade 1, or grade 2 disease. The majority of patients identified were treated with surgery, and only a small fraction of patients received radiation therapy alone or as adjuvant therapy.

Differential diagnosis of neck tumours puts precedence on diagnosing neoplastic lesions. In the case of neck tumours, these are unfortunately late signs, but in patients with a primary neoplastic focus within the head and neck, neck tumour is often the first sign of the disease. The authors describe a clinical case of neck tumour with initially unclear etiology. The preoperative diagnostics including ultrasonography, thin-needle puncture, MRI, carotid angiography and videostroboscopy was significant for surgical treatment planning; yet it was the intraoperative clinical picture which indicated that the tumour derived from the inferior parotid pole. The preoperative histopathological diagnosis using thin-needle biopsy: cellulae carcinomatosae and the clinical picture resulted in block operation with neck lymphatic system removal and tissue defect reconstruction by means of a pectoral flap. The histopathological examination confirmed non-cornifying basal cell epithelioma only in the essential lesion with no metastases to lymph nodes and surrounding tissue margins free of infiltrates. Two and a half years after the procedure, the patient presented with a tumour localized on the front thoracic wall and two rapidly enlarging tumours in the nape of the neck. In the collected specimen of the tumour on the front thoracic wall, a diagnosis of acinic cell carcinoma was made. The deteriorating general condition of the patient, his cancer emaciation, problems with movement and suspected liver metastases confirmed by abdominal USG as well as radiological bone lesions resulted in the abandonment of surgical treatment due to disseminated neoplastic process and the patient was referred for palliative care.

Partial nephrectomy (PN) preserves renal function and has become the standard approach for T1a renal cell carcinoma (RCC). However, there is still an ongoing debate as to which patients will actually derive greater benefit from partial than from radical nephrectomy (RN). The aim of this study was to retrospectively evaluate the impact of the type of surgery on overall survival (OS) in patients with localized RCC. Renal surgery was performed in 4326 patients with localized RCC (pT ≤ 3a N/M0) at six German tertiary care centers from 1980 to 2010: RN in 2955 cases (68.3%), elective (ePN) in 1108 (25.6%), and imperative partial nephrectomy (iPN) in 263 (6.1%) cases. The median follow-up for all patients was 63 months. Kaplan-Meier and Cox regression analyses were carried out to identify prognosticators for OS. PN was performed significantly more often than RN in patients presenting with lower tumor stages, higher RCC differentiation, and non-clear cell histology. Accordingly, the calculated 5 (10)-year OS rates were 90.0 (74.6)% for ePN, 83.9 (57.5)% for iPN, and 81.2 (64.7)% for RN (p < 0.001). However, multivariate analysis including age, sex, tumor diameter and differentiation, histological subtype, and the year of surgery showed that ePN compared to RN still qualified as an independent factor for improved OS (HR 0.79, 95% CI 0.66-0.94, p = 0.008). Even allowing for the weaknesses of this retrospective analysis, our multicenter study indicates that in patients with localized RCC, PN appears to be associated with better OS than RN irrespective of age or tumor size

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

Renal cell carcinoma is the most common neoplasm of the kidney comprised of different histological variants. Chromophobe renal cell carcinoma (ChRCC) is a rare subtype of renal cell carcinoma (RCC) mainly diagnosed in the sixth decade of life. It is important to identify this entity because it has significantly better prognosis than the clear cell (conventional) and papillary renal cell carcinomas. The chromophobe renal cell carcinoma should be differentiated from oncocytoma and clear cell ca...

Renal cell carcinoma (RCC) accounts for approximately 3%of all cancer cases. RCCs usually metastasize to the lungs, bones, liver, or brain. Only<1%of patients with bone metastases manifested clavicular RCC metastases. hTus, clavicular metastasis as the initial presentation of RCC is extremely rare. We report a patient with RCC metastasis to the letf clavicle, which was ifrst presented with pain caused by a pathological fracture. Magnetic resonance image revealed a renal tumor, and technetium-99m–methylene diphosphonate bone scintigraphy showed multiple osseous metastases. The patient eventually underwent surgery to remove the lateral end of the letf clavicle and right kidney. Histopathology revealed renal tumor and clear cell carcinoma in the clavicle. Finally, we review 17 cases of clavicular metastases originating from different malignancies.

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.

Transitional cell carcinoma (TCC) and large bowel obstructions are both common disease processes typically considered unrelated. Presented below is the case of a 49-year-old male with a large bowel obstruction caused by a bladder TCC metastasis. One year prior to large bowel obstruction presentation, the patient had a T2, Grade III TCC of the bladder with no nodal involvement or metastasis, which was removed via radical cystoprostatectomy. This case serves as a reminder that cancer, despite common pathogenesis patterns, can present in atypical ways. PMID:26197806

Full Text Available High-grade neuroendocrine carcinoma of the urinary bladder comprehends small-cell and large-cell variants. It is a rare and aggressive neoplasm, mostly diagnosed in advanced stages. It is more frequently encountered among Caucasian men in the sixth decade of life. Urinary symptoms are the most common clinical presentation. Diagnosis is generally not troublesome once the lesions are easily detectable by imaging exams and cystoscopy. This neoplasia is associated with tobacco smoking, and is frequently associated with other carcinomatous components such as urothelial carcinoma, adenocarcinoma, and sarcomatoid carcinoma. The authors report a case of an apparently healthy female patient who presented cervical lymph node enlargement not accompanied by systemic symptoms. The supraclavicular lymph node biopsy revealed metastatic small cell carcinoma. The computed tomography scan showed a bladder wall nodular thickening, enlarged lymph nodes along the iliac, periaortic, mediastinal, cervical and supraclavicular chains, as well as an insufflating lytic bone lesion in the right iliac wing. The positron emission tomography-fluorodeoxyglucose (PET-FDG added to these findings, the presence of a paraesophageal lymph node, lymphadenomegaly in the gluteal region and a vertebral lytic lesion in T10. Resected specimen of the bladder tumor revealed a high-grade neuroendocrine carcinoma with small-cell and large-cell features.

Renal cell carcinoma (RCC) is often concomitant with distant metastasis, and these metastases are the first sign of an otherwise occult primary. Whereas metastasis of RCC to the head and neck has been reported, metastasis to the masseter muscle, which is composed of skeletal muscle, is quite rare. We now report the case of a 66-year-old man who had a past history of pulmonary tuberculosis, with RCC metastasis of a well-defined intensely enhancing hypervascular mass in the masseter muscle as the initial presentation. We present the imaging findings of this case and a literature review about radiologic differential diagnosis of intramasseteric masses.

A case of carcinoma of the penis in a 55-year-old landlord is described. He presented with a fungating growth on the shaft of his penis with an unusual history. The lesion started as a nodule in the coronal sulcus leading to thinning of urinary stream and ultimately retention of urine, which was diagnosed and treated as a case of urethral stricture. Wedge biopsy of the growth revealed the case of squamous cell carcinoma of penis. Ultrasonography and CT scan of pelvis and abdomen proved the disease to be localized to penis and total penectomy was carried out. (author)

This was distinguished from squamous differentiation and keratotic basal cell carcinoma by a comparative study of 40 cases of compact lobular and 40 cases of keratotic basal cell carcinoma. Areas of intermediate tumour differentiation between basal cell and squamous cell carcinoma were found. Basal cell carcinomas with ...

Lung cancer-associated paraneoplastic syndromes affecting the central nervous system present significant diagnostic and treatment challenges. In this case, the patient presented with personality change, cognitive impairment, complex partial seizures, ataxia, dyspraxia, and dysphasia. Shortly after admission, the patient suffered refractory generalized tonic-clonic seizures and a decreased level of consciousness and required intubation, ventilation, and admission to the ICU. He was subsequently diagnosed with paraneoplastic limbic encephalitis based on recognized criteria, including a compatible clinical picture, elevated protein content in his cerebrospinal fluid with negative cytology, a positive positron emission tomography-computed tomography scan showing a right upper lobe tumor, and the exclusion of other neuro-oncological complications. Histopathology confirmed the tissue diagnosis as squamous cell cancer. Initial immunotherapy with steroids and intravenous immunoglobulin and subsequent lobectomy and adjuvant chemotherapy were partially successful, leading to partial resolution of his cognitive impairment. This report highlights the diagnostic and therapeutic challenges of lung-related paraneoplastic syndromes. In addition, it illustrates the poor outcomes for patients and identifies squamous cell cancer as an extremely rare cause of paraneoplastic limbic encephalitis. PMID:25784771

Horner syndrome, a combination of pupillary miosis, ptosis and facial anhidrosis, results from damage to the oculosympathetic nerve pathways. It can occur anywhere from the hypothalamus to the eye, but to our knowledge, metastatic disease to a node in the neck from a mucosal squamous cell carcinoma (SCC) of the head and neck has not previously been reported as a primary cause in humans. It is surprising that it does not present more often given the frequency of metastatic disease in the neck. We discuss how it may have occurred, and highlight the importance of a thorough examination and investigation of the head and neck in patients who present with unusual neurological signs.

Introduction. Clear cell basal cell carcinoma (BCC) is an uncommon and unusual variant of BCC, which is characterized by a variable component of clear cells. The pathogenesis of this histological variant and its clinical significance has not been clarified. Differentiation of this uncommon variant of BCC from other clear cell tumors is important for the treatment. Case Presentation. A 65-year-old male presented with a 0.9 cm dome-shaped lesion on his upper chest. A shave biopsy revealed a der...
Full Text Available Context Small cell carcinoma of the lung is an aggressive cancer with gloomy prognosis. Links to acute pancreatitis is extremely rare. Case report We are reporting a 53-year-old patient who was admitted because of acute pancreatitis. She had no history of gallstones, alcohol abuse, medications or any other predisposition for acute pancreatitis. Further investigations of blood, CT of chest abdomen and neck and ultrasound scan of abdomen, bone marrow and neck lymph node biopsies confirmed advanced small cell carcinoma of the lung with hypercalcemia, which was the only definite cause of acute pancreatitis. The patient made good recovery from pancreatitis after controlling the hypercalcemia. She was referred to respiratory team for further management of lung cancer. Conclusion Acute pancreatitis due to hypercalcemia of advanced small cell carcinoma of the lung is an extremely rare condition. Acute pancreatitis due to hypercalcemia should be thoroughly investigated to exclude serious pathology as in our case.

Basal cell carcinoma of the penis is rare. A patient who presented with a penile and scrotal ulcer due to basal cell carcinoma is reported. Wide local excision and split skin grafting were performed to excise the lesion completely.
Full Text Available Abstract We present one case with symptom of paroxysmal abdominal pain for over 20 days. Abdominal computerized tomography (CT scan revealed intestinal obstruction and a mass of 6.0 cm × 6.0 cm in size located at the left adrenal. Chest CT scan showed a lobulated mass of 2.7 cm × 2.7 cm in size at the upper left lung. Core needle biopsy of the lung mass confirmed the diagnosis of large cell carcinoma. The patient underwent an emergency abdominal laparotomy and received a chemotherapy regimen that consisted of pemetrexed and cisplatin postoperatively. In addition, we made a review of the literature of the occurrence, diagnosis and outcome of this manifestation.

Metastatic renal carcinoma is the third most common source of ocular and second most common source of orbital metastases. This is the first published case of von Hippel-Lindau (vHL) disease that developed renal cell carcinoma metastatic to an eye with a retinal hemangioblastoma. A 73-year-old woman had a history of vHL disease that included prior retinal hemangioblastomas, 2 cerebellar hemangioblastomas, and bilateral renal cell carcinomas with sacral metastasis. After presenting with progressive, painful proptosis secondary to a large mass observable by ocular CT, an enucleation-orbitotomy was performed, and the surgical specimen was sent for histopathological analysis. The ophthalmic renal metastatic tumor, like the primary tumor, was a clear cell variant that involved both the eyeball and orbit in continuity. The intraocular component was larger than the extraocular portion, which was interpreted as an outward extension of an initial retinal metastasis that probably first settled within a hemangioblastoma. Clusters of ectatic ghost vessels with thickened walls produced by periodic acid Schiff-positive, redundant basement membrane material were partially infiltrated by tumor cells at their periphery, thereby lending some support for this hypothesis. Immunohistochemical positivity for the biomarkers cytokeratin 18, vimentin, carbonic anhydrase IX, PAX2, and PAX 8 confirmed the diagnosis. The patient has refused further treatment. Her anophthalmic socket has comfortably retained a porous polyethylene implant without clinical evidence of local recurrence during 5 months of follow up. PMID:24828963

We present the case of a 60 year-old male patient who was referred to our department for surgical management of lymph node disease for UPMCC. The patient had undergone excisional biopsy of an inguinal lump, which was found to be an infiltrated lymph node by MCC. The patient underwent full imaging staging including a PET/CT, which failed to identify a primary site, and revealed only intra-abdominal lymph node disease. The patient underwent extended retroperitoneal and inguinal lymph node dissection and remains free of recurrence 16 months postoperatively.

Squamous cell carcinoma (SCC) of the bladder is uncommon, but can arise in the setting of long-term bladder catheterization and chronic inflammation. SCC can arise primarily from the suprapubic catheter tract, but fewer than 10 such cases have been reported. We document 2 cases of SCC arising from the suprapubic tract associated with chronic indwelling urinary catheters. SCC must be differentiated from granulomatous conditions, which are quite common in patients with suprapubic catheters. PMID:25132900

Small cell carcinoma (SCC) of the prostate is an uncommon condition; there are very few cases in which presenting symptoms are consistent with Cushing Syndrome (CS). We report a new case in which CS triggers the suspicion of an SCC of the prostate and a review of the published cases of SCC of the prostate presenting with CS. The origin of these neoplasms is still unclear. It may be suspected when laboratory features appear in patients diagnosed with prostatic adenocarcinoma which becomes resistant to specific therapy. SCC usually occurs after the 6th decade. Patients suffering SCC of the prostate presenting with CS usually present symptoms such as hypertension, hyperglycemia, alkalosis or hypokalemia; cushingoid phenotype is less frequent. Cortisol and ACTH levels are often high. Prostatic-specific antigen levels are usually normal. CT scan is the preferred imaging test to localize the lesion, but its performance may be improved by adding other tests, such as FDG-PET scan. All patients have metastatic disease at the time of diagnosis. Lymph nodes, liver and bone are the most frequent metastases sites. Surgery and Ketokonazole are the preferred treatments for CS. The prognosis is very poor: 2- and 5-year survival rates are 27.5 and 14.3%, respectively. Key messages When a patient presents with ectopic Cushing Syndrome but lungs are normal, an atypical localization should be suspected. We should suspect a prostatic origin if Cushing Syndrome is accompanied by obstructive inferior urinary tract symptoms or in the setting of a prostatic adenocarcinoma with rapid clinical and radiological progression with relatively low PSA levels. Although no imaging test is preferred to localize these tumors, FDG-PET-TC can be very useful. Hormone marker scintigraphy (e.g. somatostatin) could be used too. As Cushing Syndrome is a paraneoplastic phenomenon, treatment of the underlying disease may help control hypercortisolism manifestations. These tumors are usually metastatic by the

From January 1988 to December 1993, we identified six men with minimally invasive (stage I) squamous cell carcinoma of the anus and 10 men with anal carcinoma in situ (CIS). Of the six patients with invasive carcinoma, four were infected with human immunodeficiency virus (HIV), including one with AIDS. Of the 10 patients with CIS, eight were infected with HIV, including four with AIDS. Anal pain and bleeding were the most common symptoms of minimally invasive anal cancer and anal CIS. Anal irritation, burning, or pruritus occurred more frequently in patients with CIS, whereas anal ulcers, masses, or abscesses were more frequent in patients with minimally invasive cancer. Several patients with CIS had a discrete area of leukoplakia in the anal canal or a pigmented plaque of the anus and anal canal. These lesions were not observed in patients with minimally invasive anal cancer. The symptoms and signs of early-stage anal cancer in men at risk for developing HIV infection or men infected with HIV often resemble those of other common anorectal diseases in homosexual men. Anal cancer in HIV-infected men is not limited to those individuals with AIDS. PMID:8527551

Ninety percent of patients with head and neck squamous cell carcinomas (HNSCC) have overexpression of epidermal growth factor receptor (EGFR), which is correlated with poor prognosis. Complete surgical resection of HNSCC tumors has a large impact on patient survival, where detection of tumor at or close to surgical margins increases the risk of death at 5-years by 90%. In addition, large surgical margins can greatly increase the morbidity experienced by the patient due to functional and cosmetic damage of oral and facial structures. Single fluorescence targeting agents are often used for tumor detection in in vivo pre-clinical imaging; however, the arising signal is qualitative at best because it is a complex mixture of vascular perfusion, vascular leakage, inhibited lymphatic clearance, and receptor binding. In vivo ratiometric receptor concentration imaging (RCI) allows quantification of receptor expression (hence identification of cancerous tissue) by utilizing co-administered paired-agents consisting of a targeted agent and non-targeted perfusion agent to reference the plasma delivery and leakage. A panel of HNSCC tumors with varying levels of EGFR expression (SCC-15 >SCC-25 > SCC-09) have been imaged using ABY-029, a clinically relevant anti-EGFR affibody labeled with IRDye 800CW, and affibody control imaging agent labeled with IRDye 680RD. RCI maps of in vivo tissue have been created and are spatially correlated with EGFR and CD31 immunohistochemistry and basic H and E staining. The RCI threshold parameters for distinguishing tumor from normal tissues (skin and muscle) and the accuracy of margin detection in these tumors will be presented. RCI surgical resection will be further developed using a novel multi-channel, gated fluorescence-guided surgery (FGS) imaging system that is capable of performing RCI in normal room light.
Full Text Available Metastatic lesions of renal cell carcinoma (RCC occasionally regress spontaneously after surgical removal of the primary tumor. Although this is an exceptionally rare occurrence, RCC has thus been postulated to be immunogenic. Immunotherapies, including cytokine therapy, peptide-based vaccines, and immune checkpoint inhibitors have therefore been used to treat patients with advanced, metastatic RCC. We review the history, trends, and recent progress in immunotherapy for advanced RCC and discuss future perspectives, with consideration of our experimental work on galectin 9 and PINCH as promising specific immunotherapy targets.

Thymic carcinomas are very rare and heterogeneous groups of anterior mediastinum neoformations with an extremely aggressive behavior. Often, the diagnosis is made in the advanced stages. Paraneoplastic syndromes associated with thymic carcinoma are extremely rare. We report a case of a 64-year-old man presenting with early stage thymic carcinoma which was discovered because of associated paraneoplastic dermatomyositis. The dermatomyositis disappeared completely after radical resection of the tumor. After 20-month follow-up, the patient is in good clinical condition without recidivism of disease. PMID:22907201

Purpose: Breast carcinoma presenting with axillary lymphadenopathy and no clinical or radiological evidence of a primary tumor is a rare presentation. We aimed to examine the management of the breast by observation, radiation therapy, or mastectomy. Methods and Materials: Departmental records from 1979 to 1996 of unknown primary presentations and cases of T0N1-2M0 breast carcinoma were reviewed to find cases of occult breast carcinoma presenting as axillary lymphadenopathy with no clinical or imaging evidence of a primary tumor. Results: There were 6047 presentations of breast carcinoma with 20 cases of occult breast carcinoma meeting the criteria. The breast was treated by observation in 6 cases, mastectomy in 2 cases, and radiotherapy to the intact breast in 12 cases. Eighty-three percent of patients (5 of 6 patients) who had observation of the breast had a local recurrence, compared to 25% who had radiotherapy to the intact breast (3 of 12 patients) and 0% who had a mastectomy (0 of 2 patients). The median recurrence-free survival was 7 months in patients who had observation of the breast, compared to 182 months in patients who had local treatment. Three of the 6 patients who underwent breast observation have died whereas 1 of the 14 who had local treatment have died, with a mean follow-up of 73 months. It was found that patients having observation of the breast had a poorer recurrence-free survival (p = 0.003) and overall survival (p = 0.05) compared to those having local treatment of the breast. Conclusions: Patients with such a presentation should have a complete physical examination, mammography, ultrasound, and MRI of the breasts. If there remains no evidence of a primary tumor, an axillary dissection should be carried out and the breast treated by radiotherapy or mastectomy. Observation of the breast is not a recommended option

During fluorescence-guided surgery, a cancer-specific optical probe is injected and visualized using a compatible device intraoperatively to provide visual contrast between diseased and normal tissues to maximize resection of cancer and minimize the resection of precious adjacent normal tissues. Six patients with squamous cell carcinomas of the head and neck region (oral cavity (n=4) or cutaneous (n=2)) were injected with an EGFR-targeting antibody (Cetuximab) conjugated to a near-infrared (NIR) fluorescent dye (IRDye800) 3, 4, or 7 days prior to surgical resection of the cancer. Each patient's tumor was then imaged using a commercially available, open-field NIR fluorescence imaging device each day prior to surgery, intraoperatively, and post-operatively. The mean fluorescence intensity (MFI) of the tumor was calculated for each specimen at each imaging time point. Adjacent normal tissue served as an internal anatomic control for each patient to establish a patient-matched "background" fluorescence. Resected tissues were also imaged using a closed-field NIR imaging device. Tumor to background ratios (TBRs) were calculated for each patient using both devices. Fluorescence histology was correlated with traditional pathology assessment to verify the specificity of antibody-dye conjugate binding. Peak TBRs using the open-field device ranged from 2.2 to 11.3, with an average TBR of 4.9. Peak TBRs were achieved between days 1 and 4. This study demonstrated that a commercially available NIR imaging device suited for intraoperative and clinical use can successfully be used with a fluorescently-labeled dye to delineate between diseased and normal tissue in this single cohort human study, illuminated the potential for its use in fluoresence-guided surgery.
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

Full Text Available Carcinoma gall bladder is a very aggressive disease with poor outcomes. Despite achievements in the field of advanced imaging techniques, there is a very high mortality rate of the disease Cancer is the second most common disease in India responsible for maximum mortality with about 0.3 million deaths per year. The magnitude of cancer problem in the Indian Sub-continent (sheer numbers is increasing due to poor to moderate living standards and inadequate medical facilities. Women are more commonly affected than men. The peak incidence occurs in people in their 60s, but the disease age range is from 29 to 90 years of age and there is great geographic and ethnic variation. Carcinoma gall bladder, a disease of old age, is now found in the younger age group and presents with greater ferocity.

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 Abstract Pilomatrix carcinoma is the rare malignant counterpart of pilomatrixoma, a skin adnexal tumour originating from hair matrix cells. Pilomatrix carcinoma can arise as a solitary lesion de novo, or through transformation of a pilomatrixoma. Pilomatrixoma was first described erroneously as being of sebaceous gland origin but was later discovered to be derived from hair matrix cells. They are rare, slow growing tumours of the skin found in the lower dermis and subcutaneous fat and are predominantly found in the neck and the scalp. While known to be locally aggressive, no malignant form was thought to exist until it was described relatively recently. Since then, approximately ninety cases of pilomatrix carcinoma have been reported. We report the case of a 41 year old mentally retarded male who had a longstanding lesion in the left neck for approximately fifteen years previously diagnosed as a pilomatrixoma. He presented with severe headache, falls and visual disturbance and a biopsy showed pilomatrix carcinoma of the occipital region which, on computed tomography ( CT invaded the occipital bone, the cerebellum and the left temporal lobe. At his initial presentation he had a craniotomy and subtotal excision of the lesion but received no adjuvant therapy. After an early intracranial recurrence he had further debulking and adjuvant external beam radiotherapy. He has had no further intracranial recurrence after three and a half years of follow-up. Here we present the pathological features of this uncommon tumour.

Pilomatrix carcinoma is the rare malignant counterpart of pilomatrixoma, a skin adnexal tumour originating from hair matrix cells. Pilomatrix carcinoma can arise as a solitary lesion de novo, or through transformation of a pilomatrixoma. Pilomatrixoma was first described erroneously as being of sebaceous gland origin but was later discovered to be derived from hair matrix cells. They are rare, slow growing tumours of the skin found in the lower dermis and subcutaneous fat and are predominantly found in the neck and the scalp. While known to be locally aggressive, no malignant form was thought to exist until it was described relatively recently. Since then, approximately ninety cases of pilomatrix carcinoma have been reported.We report the case of a 41 year old mentally retarded male who had a longstanding lesion in the left neck for approximately fifteen years previously diagnosed as a pilomatrixoma. He presented with severe headache, falls and visual disturbance and a biopsy showed pilomatrix carcinoma of the occipital region which, on computed tomography ( CT ) invaded the occipital bone, the cerebellum and the left temporal lobe. At his initial presentation he had a craniotomy and subtotal excision of the lesion but received no adjuvant therapy. After an early intracranial recurrence he had further debulking and adjuvant external beam radiotherapy. He has had no further intracranial recurrence after three and a half years of follow-up. Here we present the pathological features of this uncommon tumour.

Cutaneous metastases can have many different clinical presentations. They are seen in patients with advanced malignant disease; however, they can be the initial manifestation of undetected malignancies. Inflammatory breast carcinoma is a rare and aggressive form of breast cancer that has a nonspecific appearance mimicking many benign conditions including mastitis, breast abscesses, and/or dermatitis. The authors report the case of a 40-year-old woman with inflammatory breast carcinoma present...

Choroidal metastases from renal carcinoma are rare. Most reported cases describe a clear cell carcinoma histologic subtype. Metastatic tubulopapillary renal cell carcinoma to the choroid plexus is very exceptional. We report the case of a 31-year-old man with a history of tubulopapillary renal cell carcinoma who presented two years later with metastatic disease to lungs and presternal soft tissue and three months after with choroidal metastasis revealed on ophtalmoscopic examination and magne...
Full Text Available Thyroid surgeons are becoming increasingly more aware of a histologically distinct subset of thyroid carcinoma whose classification falls between well-differentiated and anaplastic carcinomas with respect to both cell differentiation and clinical behavior. This subtype of tumors has been categorized as poorly differentiated or insular carcinoma, based on its characteristic cell groupings. Although the differentiation of insular carcinoma from other thyroid carcinomas has important prognostic and therapeutic significance, relatively little about insular carcinoma has been published in the otolaryngology literature. In this article, we discuss a case of insular carcinoma of thyroid presenting with concurrent distant metastasis to skull, lung, ribs, and inguinal region with review of the literature. We conclude that insular thyroid carcinoma warrants aggressive management with total thyroidectomy and excision of accessible giant lesion followed by radioactive iodine ablation of any remaining thyroid tissue.
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)
Background: We report a case of planoepitheliale cell carcinoma located in the ampulla of Vater. We report the surgical results and pathological findings of a patient with an ampullary planoepitheliale cell carcinoma. From what we know it is the first case with successful surgical treatment. Case Report: A 58-year-old woman who presented with jaundice and preoperative endoscopic and radiological procedures could not show whether the tumour was carcinoma planoepitheliale. The clinical presentation, biochemical, radiographic and endoscopic investigation pronounced advanced pancreatic adenocarcinoma. Results: We performed pancreaticoduodenectomy with curative intention. Histological examination revealed: planoepitheliale cell carcinoma of the ampullo-pancreatic unit. Conclusions: In conclusion, preoperative endoscopic and radiological evaluations can all prove insufficient to distinguish between benign and malignant tumour. Thus, for malignant tumours surgeons may be forced to perform extensive surgery. (authors)

Full Text Available Tumors of the nasosinuous tract developed in the air cavities usually present a considerable growing before the patient feel any symptom or sign. Great part of the symptomatology is given due to the invasion of the tumor to neighbour structures such as oral and nasal cavities and orbits. A case of a 62 year-old male patient is presented after being under a dental extraction. A bucco-sinuous communication was diagnosed. It did not respond to different treatments and after some moths an epidermoid carcinoma of the right maxillary sinus appeared. It is of great interest to let this case been known in order to outstand the importance of an early diagnosis to get a better vital prognosis in this kinds of lesions.

Full Text Available Xanthogranulomatous endometritis (XGE is an uncommon but well-established histopathological entity seen affecting the kidney and gallbladder. Involvement of the endometrium is very rare, with only a few case reports in world literature till date. Histologically, it is characterized by the replacement of the endometrium by sheets of foamy histiocytes, plasma cells, lymphocytes, giant cells, and siderophages. We present a case of a 74-year-old female who presented with foul-smelling discharge and postmenopausal bleeding of a short duration. Clinical examination and imaging studies revealed a pyometra, cervical stenosis. A suspicion of carcinoma was raised. Since XGE may mimic an endometrial carcinoma clinically and pathologically, knowledge of this unusual and rare inflammatory pathology is important for both the gynecologists and the pathologists.

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.
Full Text Available Thyroid carcinoma is rare comprising 1% of all malignancies and commonly presents as a neck lump. Papillary thyroid carcinoma unlike follicular thyroid carcinoma tends not to metastasise to distant sites.We present a case of papillary thyroid carcinoma presenting as a solitary asymptomatic pelvic bone metastases and highlight current management of bone metastases. A 59-year old female was found on abdominal computerised tomography to have an incidental finding of a 4.5 cm soft tissue mass in the right iliac bone. Biopsy of the lesion confirmed metastatic thyroid carcinoma. There was no history of a neck lump, head and neck examination was normal. Further imaging confirmed focal activity in the right lobe of the thyroid. A total thyroidectomy and level VI neck dissection was performed and histology confirmed follicular variant of papillary carcinoma.Early detection of bone metastases have been shown to improve prognosis and thyroid carcinoma should be considered as a potential primary malignancy.

Simultaneous occurrence of multifocal urothelial carcinoma (UC) and ipsilateral renalcell carcinoma (RCC) is rare. We report a 67-year-old woman with multifocal, infiltratingurothelial carcinoma and unilateral renal cell carcinoma. She was referred to our departmentbecause of painless gross hematuria. Cystoscopy, computed tomography and retrogradepyelography studies revealed bladder, bilateral renal and ureter UC. She was treated withtransurethral resection of the bladder tumor followed by bi...
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.

A multifocal biphasic squamoid alveolar renal cell carcinoma in a 68-year-old man is reported. Four different peripheral tumor nodules were identified on gross examination. A fifth central tumor corresponded to a conventional clear cell renal cell carcinoma. Biphasic squamoid alveolar renal cell carcinoma is a rare tumor that has been very recently characterized as a distinct histotype within the spectrum of papillary renal cell carcinoma. Immunostaining with cyclin D1 seems to be specific of this tumor subtype. This is the first reported case with multifocal presentation. PMID:27158455
Full Text Available Basal cell carcinoma preferentially occurs in the face where the surgical excision with adequate margin is curative. Sometimes basal cell carcinoma is also reported rarely in other sites especially associated with basal cell carcinoma syndrome. The histological variants are Nodular basal cell carcinoma, Keratotic basal cell carcinoma, Adenoid basal cell carcinoma, Basal cell carcinoma with sebaceous differentiation. Of these variants, Basal cell carcinoma with eccrine differentiation is practically very rare.

Cryotherapy has proved to be an effective tool in the management of various dermatoses. We report 6 patients with histopathologically proven basal cell carcinoma of variable sizes treated with liquid nitrogen cryotherapy by the open spray technique. Lesions tended to heal with depigmentation and scar formation. However depigmented areas often repigmented over a period of time.
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)

Large cell neuroendocrine carcinomas of the ampulla of Vater are rare and confer a very poor prognosis despite aggressive therapy. There are few case reports of large cell neuroendocrine carcinomas of the ampulla of Vater in the literature and to date no studies have been done to establish optimal management. We describe a pooled case series from published reports of neuroendocrine carcinomas of the ampulla of Vater including a case which presented to our institution.

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.

Primary squamous cell carcinoma of the thyroid gland is rare, and mixed squamous cell and follicular carcinoma is even rarer still, with only a few cases reported in the literature. The simultaneous presentation of three primary cancers of the thyroid has not been reported previously. Here we report a case of primary squamous cell carcinoma of the thyroid, follicular thyroid carcinoma, and micropapillary thyroid carcinoma. A 62-year-old female patient presented with complaints of pain and a 2-month history of progressively increased swelling in the anterior region of the neck. Fine-needle-aspiration cytology of both lobes indicated the possibility of the presence of a follicular neoplasm. Total thyroidectomy with left-sided modified radical neck dissection was performed. Postoperative pathological examination confirmed the diagnosis of thyroid follicular carcinoma with squamous cell carcinoma and micropapillary carcinoma of the thyroid. Thyroid-stimulating hormone suppressive therapy with l-thyroxine was administered. Radioiodine and radiotherapy also were recommended, but the patient did not complete treatment as scheduled. The patient remained alive more than 9 months after operation. The present case report provides an example of the coexistence of multiple distinct malignancies in the thyroid. PMID:26589365

Full Text Available Skeletal metastasis as a primary presentation of gall bladder carcinoma is rare. A 50-year-old lady presented with neck pain and weakness in her right upper limb of 3 months duration. Clinical and imaging work-up suggested locally advanced gall bladder carcinoma with metastasis to cervical vertebra and sternum. Only one case till date has been reported where the patient presented with neurological symptoms due to pathological fracture secondary to metastasis from an occult gall bladder carcinoma. Although rare, an occult gall bladder cancer may present with neurological symptoms due to pathological fracture of spine secondary to metastasis. We present a brief review of literature of patients who presented with skeletal metastases in clinically silent gall bladder malignancy. Palliative care issues in advanced gall bladder carcinoma have also been discussed.

A 58-year-old woman with a 2-month history of atypical chest pain was referred to the chest pain clinic by the general practitioner. Exercise stress test was positive and subsequent coronary angiogram revealed significant triple vessel disease with left ventricular impairment requiring a coronary artery bypass graft (CABG). The patient had a chest X-ray as part of the preoperative work up. Chest X-ray revealed a large anterior mediastinal mass. Subsequent thorax CT revealed a 7.2 cm anterior mediastinal mass. CT-guided biopsy of the mass revealed the diagnosis of a poorly differentiated thymic basaloid carcinoma. The patient was successfully treated with concomitant surgery involving complete resection of the mass and a CABG procedure. PMID:26607199
Basal cell carcinoma is the most easily cured carcinoma, but because of the many forms it can take, and because it grows so slowly, it can be misdiagnosed or neglected. The author discusses its more common forms and etiologic considerations.
Full Text Available Laryngeal carcinoma is rarely associated with paraneoplastic syndrome. Inflammatory myopathy presenting as paraneoplastic event is commonly associated with carcinomas of ovary, lung, pancreas, stomach, colorectal, and non-Hodgkin′s lymphoma. We report a case of elderly male, who presented with proximal muscle weakness and found to be associated with laryngeal carcinoma. Diagnosis of polymyositis (PM was confirmed based on clinical features, laboratory test, and muscle biopsy. Exclusion of other commonly associated malignancies was done. This patient improved gradually after 6 months of immunosuppressive therapy and management of underlying cancer.
An interesting case of a 09 years old girl is reported who presented with a painless, mobile, spherical, fluctuant and brilliantly translucent swelling in front of left ear. The fine needle aspiration revealed turbid dark yellow colour fluid. This cystic swelling was completely excised and the specimen on histopathology was reported as low grade Mucoepidermoid carcinoma. Recovery was uneventful. This unusual presentation of Mucoepidermoid carcinoma as a preauricular cyst is one of the rare unique reported case. (author)

An eight-year-old, neutered male Burmese cat presented with five days vomiting and anorexia. Physical examination, clinical pathology and diagnostic imaging findings suggested a perirenal pseudocyst. After partial resection of the perirenal capsule clinical signs temporarily resolved, but the cat was euthanased 34 days postoperatively as a result of seizures and recurrence of vomiting. Postoperative histopathology showed neoplastic transitional cells within and lining the resected perirenal capsule; a diagnosis of transitional cell carcinoma was confirmed post-mortem. To the authors' knowledge, this is the first report of this presentation of transitional cell carcinoma. Transitional cell carcinoma should be a differential diagnosis for the aetiology of perirenal pseudocyst. PMID:17784930

associated with its cause. However, other elements of risk are described, such as light skin phototypes, advanced age, family history of skin carcinoma, light eyes and blond hair, freckles in childhood and immunosuppression. Behavioral aspects such as occupational sun exposure, rural labor and sunburns at a young age also play a role. Between 30% and 75% of the sporadic cases are associated with patched hedgehog gene mutation, but other genetic changes are also described. The tumor is commonly found in concomitance with skin lesions related to chronic sun exposure, such as actinic keratoses, solar lentigines and facial telangiectasia. The prevention of basal cell carcinoma is based on the knowledge of risk factors, early diagnosis and treatment, as well as on the adoption of specific measures, particularly in susceptible populations. The authors present a review of the epidemiology of basal cell carcinoma.

Full Text Available Xp11 translocation renal cell carcinoma (TRCC is a rare subtype of renal cell carcinoma characterized by chromosomal translocations involving the TFE3 gene located at the Xp11.2 locus. Initial cases were more common in children, but cases in older adults have begun to accrue and suggest a relatively more aggressive course. We report a case of Xp11 TRCC in a 63-year-old female patient with initial presentation mimicking upper urinary tract urothelial cell carcinoma, with biopsy proving TRCC. She underwent a radical nephrectomy and paracaval lymph node dissection and is followed up with the intent to initiate vascular endothelial growth factor–targeted therapy in case of recurrence.

Renal cell carcinoma is the most common type of renal malignancy and it originates from the renal tubular epithelium. Due to the diversity in the histopathological and molecular characteristics, it is typically subclassified into five different categories. Papillary renal cell carcinoma is one subclassification and it includes two variants: sporadic and hereditary. Although the hereditary form comprises a smaller number of cases of papillary renal cell carcinoma, an understanding of the molec...

Basal cell carcinoma (BCC) is the most common nonmelanoma skin cancer. Most BCCs are found on areas of UV-damaged skin, The study of BCCs of sun-protected regions, however, suggests a more complex pathogenesis. We present a case of BCC of the perineum in a man with no previous history of skin cancer. This is the first report of BCC in this region and one of a small body of cases arising on or near the genital and perianal regions.

Bony metastases develop in 30% of all the cancers, but out of which only 1% to 3% occurs in the hand. Lung is the most common site for acrometastasis, followed by breast and renal cell cancer. Metastases to the digits are with non-specific presentation. We reported a case of 79-year-old male patient with initial presentation of swelling over left index finger, which was found to be squamous cell carcinoma of finger on histopathological examination. He was subsequently diagnosed as a case of squamous cell carcinoma of lung with acrometastasis. PMID:27504389

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 Small cell carcinoma of bladder, which does not have a common and accepted treatment protocol, is a rare and highly aggressive tumor. It is mostly pulmonary originated; however, it can rarely be seen in extrapulmonary sites. We presented an interesting and uncommon case, in which the transitional cell tumor was found in the transurethral resection specimen, but the small cell carcinoma was detected in the final radical cystectomy material.

Full Text Available Carcinoma en cuirasse is a form of cutaneous metastasis. Although this condition is rare, it is most commonly associated with breast carcinoma with local recurrence after mastectomy. Cutaneous metastasis presents most commonly a few months or years after the primary has been diagnosed. Less frequently a metastasis is diagnosed at the same time as the primary tumor or presents as the first manifestation of the disease. We report a case of carcinoma en cuirasse in a 50-year-old female who presented with elevated, finely nodular, indurated skin lesions on left anterior chest wall, axillary region and keloid - like patch on left upper arm. On further examination a breast mass was detected. Fine needle aspiration of all the lesions was performed. Cytodiagnosis was given as infiltrating duct carcinoma of breast with metastatic carcinoma involving left anterior chest wall, axilla and left upper arm. We should not disregard keloid-like or indurated patches on skin which should be investigated thoroughly.

Objective: To analyze the CT features of renal cell carcinoma, so as to improve the diagnostic accuracy of renal cell carcinoma. Methods: Three hundred cases of renal cell carcinoma proved by pathology were examined by means of CT. There were 214 male and 86 female in this group. Their age ranged from 9 to 81 years, with a mean of 53.7 years. Their CT features were retrospectively reviewed. Results: The masses were 1.5-16.0 cm (mean, 4.8 cm) in greatest dimension, 125 masses on left kidney and 175 masses on right kidney. According to WHO histological classification of tumours of the kidney in 2004, there were 238 cases of clear cell renal cell carcinoma, 6 cases of multilocular clear cell renal cell carcinomas, 23 cases of papillary renal cell carcinoma, 14 cases of chromophobe renal cell carcinoma and 19 eases of renal cell carcinoma, unclassified. The above subtype of renal cell carcinoma demonstrated characteristic features. Clear cell renal cell carcinoma exhibited inhomogenous (due to hemorrhage, necrosis or cystic degeneration) and hypervascular. Multilocular clear cell renal cell carcinoma presented as a multilocular cystic mass lacking an expansile nodule, and with regular thin cyst wall and septa. Papillary renal cell carcinoma exhibited inhomogenous and hypovascular. Chromophobe renal cell carcinoma was relatively homogenous and hypovascular. Renal cell carcinoma, unclassified showed inhomogenous and hypervascular, and was more invading growth compared to clear cell renal cell carcinoma. Conclusion: Common subtype of renal cell carcinoma demonstrated characteristic features in CT and it is helpful for differentiation. (authors)

Full Text Available We previously published our and Johns Hopkins data titled: "Platinum-based therapy in adenosquamous pancreatic cancer: experience at two institutions” . 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 . 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 . 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 . 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

Small cell lung carcinoma (SCLC) commonly metastasizes to distant organs. However, metastasis to the pancreas is not a common event. Moreover, obstructive jaundice as a first clinical presentation of SCLC is extremely unusual. This case reports a 51-year-old male with SCLC, manifesting with obstructive jaundice as the initial clinical presentation. Endoscopic retrograde cholangiopancreatograghy (ERCP) and abdominal computed tomography (CT) scan showed a mass at the head of the pancreas. The patient underwent pancreatoduodenectomy (Whipple procedure). Histopathology revealed a chromogranin- A-positive poorly-differentiated neuroendocrine carcinoma of the pancreas. No imaging study of the lung was performed before surgery. A few months later, a follow-up CT revealed unilateral lung nodules with ipsilateral hilar nodes. A lung biopsy was done and histopathology reported a TTF- 1-positive, chromogranin A-positive, small cell carcinoma of the lung. On review, the pancreatic tumour was also TTF-1-positive. He was then treated with combination chemotherapy (cisplatin, etoposide). These findings highlight that presentation of a mass at the head of pancreas could be a manifestation of a metastatic tumour from elsewhere such as the lung, and thorough investigations should be performed before metastases can be ruled out.

Full Text Available Abstract Background Leptomeningeal carcinomatosis occurs in patients with cancer at the rate of approximately 5%; it develops particularly in patients with breast cancer, lung cancer, melanoma, leukemia, or malignant lymphoma. We describe a rare case of leptomeningeal carcinomatosis in which spinal intradural squamous cell carcinoma with no lesions in the cerebral meninges and leptomeninx, was the primary lesion. Methods A 64-year-old man complained of sacral pain. Although the patient was treated with analgesics, epidural block and nerve root block, sacral pain persisted. Since acute urinary retention occurred, he was operated on. The patient was diagnosed as having an intradural squamous cell carcinoma of unknown origin. Results Since the patient presented with a slightly decreased level of consciousness 2 months after surgery, he was subjected to MRI scanning of the brain and spinal cord, which revealed disseminated lesions in the medulla oblongata. The patient died of pneumonia and sepsis caused by methicillin-resistant Staphylococcus aureus 5 months after surgery. Conclusion We report the first case of a patient with intradural squamous cell carcinoma with unknown origin that developed independently in the sacrum.

Full Text Available Spindle cell carcinoma (SpCC is a unique variant of squamous cell carcinoma (SCC. SpCC confined to the nasal cavity is extremely rare, with only one case having been previously reported. We present a case report of nasal cavity SpCC and review the literature on this rare entity. A 29-year-old male presented with intermittent epistaxis from the left nasal cavity. On physical examination, the patient had an ulcerated mass in the left nasal vestibule and a biopsy showed a proliferation of spindle and epitheliod cells. The patient underwent wide local excision of the mass via a lateral alotomy approach and reconstruction with a composite conchal bowl skin and cartilage graft. Histologically, the mass had dyplastic squamous epithelium and spindle-shaped cells admixed with epitheliod cells. Immunohistochemistry was only positive for pancytokeratin AE1/AE3 and vimentin. Six months after surgery, the patient continues to have no evidence of disease. On literature review, only one previous case of SpCC confined to the nasal cavity was identified. We present a rare case of nasal cavity SpCC. No definite treatment protocol exists for this unique entity, but we believe that this tumor should primarily be treated with aggressive, wide local excision. Adjuvant radiation and/or chemotherapy have also been used anecdotally.

Full Text Available Abstract Renal cell carcinoma constitutes about 3% of adult malignancies. It has a high metastatic potential associated with synchronous or metachronous metastatic disease. Further, it is known to metastasize mainly to the lung, bone, brain, liver, or adrenal glands. In very rare cases it can metastasize to the gallbladder mimicking acute cholecystitis on clinical exam. In this case we present a patient who developed a gallbladder metastasis five years after a renal cell carcinoma mimicking acute cholecystitis.

Squamous cell carcinoma (SCC) of the endometrium, whether primary or secondary to cervical cancer, is a rare entity. Primary endometrial squamous cell carcinoma in situ is even more uncommon; it usually occurs in postmenopausal women and has a strong association with pyometra. We report a 60-year-old multiparous postmenopausal woman who presented to the Hakeem Abdul Hameed Centenary Hospital, New Delhi, India, in May 2014 with a lower abdominal swelling corresponding in size to a pregnancy of 26 gestational weeks and vaginal discharge of one year’s duration. A total abdominal hysterectomy with a bilateral salpingooophorectomy was performed, which revealed an enlarged uterus with pyometra. Histopathology showed that the entire endometrial lining had been replaced with malignant squamous cells without invasion of the myometrium. Immunohistochemistry revealed that the tumour cells were positive for p63 with a high Ki-67 labelling index. No adjuvant therapy was required and the patient was disease-free at a seven-month follow-up. PMID:26629388

Background Papillary renal cell carcinoma, accounting for 15% of renal cell carcinoma, is a heterogeneous disease consisting of different types of renal cancer, including tumors with indolent, multifocal presentation and solitary tumors with an aggressive, highly lethal phenotype. Little is known about the genetic basis of sporadic papillary renal cell carcinoma; no effective forms of therapy for advanced disease exist. Methods We performed comprehensive molecular characterization utilizing whole-exome sequencing, copy number, mRNA, microRNA, methylation and proteomic analyses of 161 primary papillary renal cell carcinomas. Results Type 1 and Type 2 papillary renal cell carcinomas were found to be different types of renal cancer characterized by specific genetic alterations, with Type 2 further classified into three individual subgroups based on molecular differences that influenced patient survival. MET alterations were associated with Type 1 tumors, whereas Type 2 tumors were characterized by CDKN2A silencing, SETD2 mutations, TFE3 fusions, and increased expression of the NRF2-ARE pathway. A CpG island methylator phenotype (CIMP) was found in a distinct subset of Type 2 papillary renal cell carcinoma characterized by poor survival and mutation of the fumarate hydratase (FH) gene. Conclusions Type 1 and Type 2 papillary renal cell carcinomas are clinically and biologically distinct. Alterations in the MET pathway are associated with Type 1 and activation of the NRF2-ARE pathway with Type 2; CDKN2A loss and CIMP in Type 2 convey a poor prognosis. Furthermore, Type 2 papillary renal cell carcinoma consists of at least 3 subtypes based upon molecular and phenotypic features. PMID:26536169
Pancreatic cancer is characterized by its late detection, aggressive growth, intense infiltration into adjacent tissue, early metastasis, resistance to chemo- and radiotherapy and a strong “desmoplastic reaction”. The dense stroma surrounding carcinoma cells is composed of fibroblasts, activated stellate cells (myofibroblast-like cells), various inflammatory cells, proliferating vascular structures, collagens and fibronectin. In particular the cellular components of the stroma produce the tumor microenvironment, which plays a critical role in tumor growth, invasion, spreading, metastasis, angiogenesis, inhibition of anoikis, and chemoresistance. Fibroblasts, myofibroblasts and activated stellate cells produce the extracellular matrix components and are thought to interact actively with tumor cells, thereby promoting cancer progression. In this review, we discuss our current understanding of the role of pancreatic stellate cells (PSC) in the desmoplastic response of pancreas cancer and the effects of PSC on tumor progression, metastasis and drug resistance. Finally we present some novel ideas for tumor therapy by interfering with the cancer cell-host interaction

The clinical and pathological findings in three patients with clear cell carcinoma of the larynx are described. This type of neoplasm in the larynx is extremely rare. The aggressiveness of the tumour and its high biological malignancy are stressed.
Findings from clinical trial patients with metastatic renal cell carcinoma, a common kidney cancer, show they did not have accelerated tumor growth after treatment with sunitinib, in contrast to some study results in animals.
Fibrolamellar hepatocellular carcinoma is a rare primary malignant liver tumor, significantly different from generic hepatocellular carcinoma with distinct demographics, risk factors, imaging features, histopathology and prognosis. Unlike conventional hepatocellular carcinoma, it presents in young individuals with no preexisting hepatitis or cirrhosis and does not cause elevation of serum alpha feto proteins in most cases. This paper presents a case report of this rare tumor in a young female with an unusual clinical manifestation of obstructive jaundice (which has not been reported so far) along with a review of its imaging and pathological features, with treatment options. Fibrolamellar HCC is a rare variant of classic HCC with different epidemiology, risk factors, clinical manifestations, radiological, pathological and prognostic features. Therefore, it is important to be familiar with the entity for its early diagnosis and management

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.

Breast cancer in men is uncommon, accounting for ratio and familial history (BRCA 2 and 1). The authors present a case of a 52-year-old man with no relevant predisposing factors to breast cancer, who presented with a painless, firm nodule, fixed to the nipple on the left breast, associated with nipple retraction and ulceration, and fully characterised by mammogram and ultrasound. Histopathological and immunohistochemical analysis revealed the diagnosis of invasive lobular breast carcinoma and the patient underwent left radical mastectomy, followed by adjuvant chemotherapy, radiotherapy and hormonotherapy. A brief review of the literature is presented. PMID:27151060

A 63-year-old man consulted for a non-toxic thyroid nodule of 2 years’ duration. Fine needle aspiration revealed cell findings consistent with papillary thyroid carcinoma. He eventually underwent total thyroidectomy. Microscopic examination revealed histologic features of Hurthle cell carcinoma of the thyroid. He received radioactive iodine therapy and suppressive levothyroxine treatment. Post-therapy whole body iodine-131 scan revealed thyroid tissue remnants limited to the anterior neck. Fo...
Squamous cell carcinoma of the anal canal is rather rare and amounts to 3.5% of all rectal neoplasms. Though it has a clear-cut clinical picture, 29.5% of patients admitted for specialized treatment suffer from stage 4 due to inadequate diagnosis. Surgery is the most effective method of management of squamous cell carcinoma of the anal canal. Radiation therapy may be an adjuvant procedure to surgery

Abstract Nevoid basal cell carcinoma syndrome (NBCCS), also known as Gorlin syndrome, is a hereditary condition characterized by a wide range of developmental abnormalities and a predisposition to neoplasms. The estimated prevalence varies from 1/57,000 to 1/256,000, with a male-to-female ratio of 1:1. Main clinical manifestations include multiple basal cell carcinomas (BCCs), odontogenic keratocysts of the jaws, hyperkeratosis of palms and soles, skeletal abnormalities, intracranial ectopic ...
Full text: A rare case of renal transitional cell carcinoma (TCC) associated with bland thrombus of the renal vein extending into the inferior vena cava is described. Tumour thrombus in renal cell carcinoma is frequently encountered, but only very rarely occurs with TCC. Bland renal vein thrombosis occurring with renal TCC has not been described before. Contrast enhanced computed tomography assisted in distinguishing between bland and tumour thrombosis and aided in surgical management
