BACKGROUND Merkel cell carcinoma (MCC) is an uncommon but aggressive cutaneous skin cancer. Even with the appropriate treatment, MCC is prone to recurrence, and metastases are common. Exposure to ultraviolet radiation has been suggested as contributing towards the development of MCC. MCC has not been extensively investigated in Australia, even though(More)
The clinical and histological features of 171 atypical fibroxanthomas (AFX) from a single institution in Western Australia are outlined. This area experiences high levels of solar radiation, and all assessable biopsies showed solar elastosis. Patients were aged between 41 and 97 years (median age 74), with 76% of tumors occurring in men (male to female(More)
The diagnosis of diffuse axonal injury (DAI), which may be of considerable importance in forensic medicine, necessitates widespread sampling of the brain for histology. Because a limited sampling method for screening brains for axonal damage would be of value for medico-legal work, the authors have tested the findings of an earlier study which suggested(More)
AIMS Seventy-five skin tumours were studied to investigate the value of immunohistochemistry in differentiating basal cell, squamous cell and basosquamous carcinomas of the skin. METHODS AND RESULTS Archived paraffin-embedded tissue samples of basal cell carcinomas (n = 39), squamous cell carcinomas (n = 23) and basosquamous carcinomas (n = 13) were(More)
The aims of this study were to evaluate the use of the proliferation marker MIB 1 and histological subtype as indicators of prognosis in malignant mesothelioma. Sections from 41 cases of malignant mesothelioma were histologically subtyped on hematoxylin and eosin sections and stained immunohistochemically for the proliferation marker MIB 1. A proliferation(More)
Angiomyolipomas are uncommon tumors in the skin. Neoplasms with the same name are more typically associated with a renal location, many in the context of tuberous sclerosis. Three cases of cutaneous angiomyolipoma are reported, which were all HMB45 negative and not associated with tuberous sclerosis. This is the first series of such tumors to be stained(More)
AIMS To document the histopathological features of self-treatment of cutaneous lesions with the escharotic agent black salve. METHODS Retrospective review of cutaneous lesions treated with black salve retrieved from the files of four pathology practices in Western Australia and review of the published literature. RESULTS 16 lesions from 11 patients who(More)
BACKGROUND Mohs surgeons have expanded the range of cancers treated using the Mohs technique. Mohs surgeons today are expected to diagnose perineural invasion (PNI) when as little as one nerve is involved. OBJECTIVE To address the issue of identification and significance of perineural invasion from the perspective of the Mohs surgeon. The experience of(More)
