Histopathological study on basal cell carcinoma and squamous cell carcinoma of the skin

A collaborative study on skin cancer h.as been conducted to analyze the risk factors and clinico-pathological characteristics of skin cancers among both thc Indonesian and the Japanese. In this sndy, we have analyzed the histopathological features of non-melanoma skin cancer (NMSC), basal cell carcinoma (BCC) and squamous cell carcinoma (SCC) of Indonesian patients. Considering the fact that uhravioLet light (UV) radiation is the major cause of NMSC, we focus on studying the relationship between the histopathoLogical fnding and the location of the tumors, whether they were developed on swt-e4tosed sites or sun-protected sites. In addition, because it has been revealed thot the size of NMSC in Indonesian was larger than those in Japanese, we also attempted to find the relationship betyveen the tumor size of NMSC and the pathological characteristics. From period of 1996 to 1998, we could analyze the histopathological feotures in 40 cases of BCC and 16 cases
