Clear Cell Change

Background: Clear cell squamous cell carcinoma (ccSCC) is an uncommon subtype of squamous cell carcinoma. This tumor subtype arises more commonly in elderly individuals and occurring greater upon sun-exposed areas of the body.Objective: To determine the age range and locations of ccSCC, and occurrence in men as compared with women.Methods: An observational study of ccSCC accessioned at a dermatopathology laboratory (Cleveland Skin Pathology, CSP) over an 18-month interval. Cases were retrieved and included based on a search of the terms “clear cell squamous cell carcinoma” in the diagnosis field of the CSP database and reviewed for accuracy and the degree of clear cell change in each lesion. Pathology requisition forms from these cases were used only to identify patients’ age, gender, and anatomic region of the ccSCC reviewed.Results: Of the 17,838 cases of in situ and invasive SCC, there were a total of 107 ccSCC, 77 in situ and 30 invasive (0.6% of total SCC). Of patients with ccSCC, 71% had a history of skin cancer, many (57.9%) in the same anatomic region. When the degree of clear cell change was evaluated there was no statistically significant increase of percentage clear cell change in tumors with age.Conclusions: Along with confirming past observations made with previous studies, our series shows that more men than women develop such tumors before 70 years of age, and more women than men after 70 years of age with men developing ccSCC on average 7 years earlier than women.

Abstract We present a unique carcinoma of the pancreas with predominantly clear cell morphology (>95% clear cells). Mucicarmine stain revealed abundant intraluminal and intracytoplasmic mucin. Immunohistochemically, the cells were positive for the epithelial markers cytokeratin 7 and CAM 5.2, and were focally positive for cytokeratin 20. These cells also expressed monoclonal carcinoembryonic antigen. Stains for the neuroendocrine markers synaptophysin and chromogranin were negative, as were stains for vimentin, p53, HMB-45, and CD10. An additional outstanding feature was the presence of dense intraluminal and intracytoplasmic hyaline globules, which were immunohistochemically positive for α1-antitrypsin. Sequencing of the K-ras oncogene revealed a point mutation in codon 12, providing molecular evidence of ductal origin. In the proper morphologic context supported by immunohistochemistry, clear cell carcinoma can be regarded as a rare variant of ductal adenocarcinoma.

The authors present the autopsy findings of two related patients and the biopsy findings of a thrid member of the family. The oldest member was 34 years old at death and on postmortem examination he had haemangioblastomas in the retina, cerebellum, medulla and spinal cord. Other findings were renal cell carcinoma, phaechromocytoma, cysts of kidney and pancreas, hydromyelia and atypical meningiomas. His brother died when 30 years old. The autopsy revealed haemangioblastomas of cerebellum, renal cell carcinoma and a clear cell cystadenoma of epididymus. The third patient was the daughter of the first and presented with headache and dizziness. CT-scan showed a cerebellar haemangioblastoma. Epidemiological considerations on the commonest visceral and CNS lesions and a review of current diagnostic criteria are discussed.
