The number of patients with basal cell carcinoma (BCC) treated at our department has been increasing in recent years. We statistically studied seventy-six specimens from seventy-three cases diagnosed as BCC from 1991 to 2000.
There were fewer than ten cases of BCC per year from 1991 to 1996, while there were more than ten cases per year in 1997, 1998 and 2000. The patients consisted of forty-two men and thirty-one women. Sixty-one patients were more than sixty years old. The locus of the BCC in forty-four cases (57%) was the face, in fifteen it was the trunk, in six it was the lower extremities, in four each it was the upper extremities and the pubic region, in two it was the scalp, and in one it was the neck.
The clinical classification of noduloulcerative type was observed in fifty-seven cases (75%), superficial type was observed in twelve, epithelioma-planum-cicatricans type and morphea-like type were observed in three cases each, and epithelioma-terebrans type was observed in one. The histopathological classification of solid type was observed in fifty cases (66%), superficial type was noted in ten, adenoid type was noted in seven, keratotic type was observed in five, morphea-like type was noted in three, and cystic type was observed in one.
