Because it is not possible to monitor skin cancer accurately using routine methods, special surveys have been undertaken in Nambour, a typical subtropical community in Queensland, Australia. Estimates of incidence reported here are based on skin cancers medically treated between 1985 and 1992 and new cases diagnosed by dermatologists in two examination(More)
Apoptosis is a distinctive mode of cell death with characteristic morphologic features which serves as a balance to mitosis in regulating the size of animal tissues. In contrast to coagulative necrosis, the cytologic features of apoptosis suggest active self-destructive rather than progressive disintegration. It typically affects scattered individual cells(More)
Atypical fibroxanthoma is a controversial entity with a disputed histogenesis. It has recently been suggested that most atypical fibroxanthoma are actually variants of squamous cell carcinoma. We reviewed 100 purported cases of atypical fibroxanthoma received over 4 years to perform clinical follow up and immunohistochemical markers. In particular, we(More)
BACKGROUND/OBJECTIVES Tinea nigra is a relatively uncommon dematiaceous fungal infection of the palms and soles, which clinically may mimic a melanocytic lesion. We sought to ascertain how frequently misdiagnosis of this infection occurred and whether the use of dermoscopy helped in its diagnosis. METHODS Fifty consecutive cases of tinea nigra diagnosed(More)
A large series of 211 Spitz nevi is reviewed. 30% of the lesions were from patients 20 years of age and over. The trunk and lower extremity were most commonly involved. There were no significant histologic differences between cases from adults and children. Features which may help in differentiating atypical Spitz nevi from malignant melanoma include the(More)
BACKGROUND Skin cancer is an increasing problem in fair-skinned populations worldwide. It is important that doctors are able to diagnose skin lesions accurately. OBJECTIVES To compare the clinical with the histological diagnosis of excised skin lesions from a set of epidemiological data. We analysed diagnostic accuracy stratified by histological subtype(More)
Following an increase in the reported incidence of melanoma of Hutchinson's melanotic freckle type (HMFM) in Queensland, a review of its histological diagnosis was undertaken. Ninety-nine pigmented lesions reported by 13 different pathology laboratories throughout Queensland as having an in-situ component of Hutchinson's melanotic freckle (HMF) were(More)
