title: [Profile of basal cell carcinomas of the scalp after radiotherapy for tinea capitis (about 63 cases)].
abstract: The induction of basal cell carcinoma (BCC) of the scalp by X-ray therapy for tinea capitis is well known. The aim of the study was to specify the epidemiological, clinical and histological characteristics of this disease. In a retrospective study, we collected data from the files of 63 patients, with a history of radiotherapy for tinea capitis, followed between January 1995 and December 2004. Fifty one men and 12 women with a total of 108 BCC of the scalp are reported (1.76 lesion per patient and 1.13 cm on average of diameter). The mean age at the occurrence of the BCC was 45.5 years. Thirty seven percent of BCC occurred on the occipital area; 28.7% were in the parietal site. The most frequent clinical aspect was the nodular BCC (51%) and the cicatricial BCC (35%). Histological study showed a nodular aspect in 74 % and pigmentation in 62% of cases. It is concluded that BCC of the scalp following X-ray therapy for tinea capitis have some clinical and histological particularities. It represents the most frequent tumour developing on irradiated scalp.
