Basal cell carcinoma in Turkey.

Basal cell carcinoma (BCC) is the most common form of cancer in Caucasians. This study was undertaken to define the clinical features of BCC treated by surgical excision in Turkish patients. A group of 198 patients with 216 BCCs, all treated by surgical excision, were studied prospectively. The age and sex distribution, personal and family histories of the patients, skin type, sites and sizes of the lesions, clinical types of the lesions, status of the surgical margins, and incidences of recurrence were analyzed. The male to female ratio was 0.9, and the average age of the patients was 64.5 years. Of the tumors, 91.5% occurred on the head and neck. There were also personal and/or family histories of cancer in 24.8% of our cases. Of all BCCs treated, 83.8% had a noduloulcerative clinical appearance. The vast majority of our patients were Fitzpatrick type 3 (53.0%) and type 2 (41.5%). There were seven recurrences after follow-up periods varying between three months and two years. In conclusion, the clinical characteristics of BCC in Turkish patients have both similarities and differences compared to those of other countries.
