OBJECTIVE To determine the incidence and clinical characteristics of non-melanoma skin cancer in Hong Kong Chinese patients. DESIGN Retrospective study. SETTING Social Hygiene Services, Hong Kong. PATIENTS Records of 528 Chinese patients with a histological diagnosis of non-melanoma skin cancer from 1990 to 1999 were reviewed. MAIN OUTCOME MEASURES Demographic data, site and clinical ty...

BACKGROUND A dermoscopic method based on the absence of a pigment network and the presence of at least one of six positive features has been described for diagnosis of pigmented basal cell carcinoma (BCC). OBJECTIVE To evaluate the observers' global agreement and interobserver agreement on each dermoscopic parameter of the method recently proposed. METHODS Dermoscopic images of 56 pigmented...

In this work, Raman and autofluorescence spectroscopy in the near-infrared region has been used for examining amelanotic melanoma as most dangerous type of malignant melanoma. There were 9 patients with melanoma, 60 pigmented 120 basal cell carcinoma enrolled study. We studied cases to differentiate them from (n = 120) 60) using portable setup laser excitation source at 785 nm low-cost spectrom...

A case of pigmented basal cell carcinoma developing in a smallpox revaccination site is presented. Any progressive change within a smallpox vaccination scar should be thoroughly evaluated and treated appropriately after tissue diagnosis.
