RESUMO
A 12-year-old girl had a lesion located on the upper part of the scalp that was clinically interpreted as a melanocytic nevus and corresponded histologically to a basal cell carcinoma. At age 2 years she had been diagnosed as having acute lymphoblastic leukemia L1, for which she was treated with systemic chemotherapy. She also received telecobalt therapy to the whole cranium for prophylaxis of meningeal leukosis. Having rejected other possible causes that can favor the appearance of basal cell carcinoma during childhood (basal cell nevus syndrome, nevus sebaceus, albinism, etc.), we believe that this case should be added to the five previously reported in the literature as basal cell carcinoma developing at an early age in cranial radiation portals with megavoltage radiotherapy. We draw attention to the need to explore radiated areas of skin as part of the long-term follow-up of these patients, and to the advisability of obtaining a biopsy from any persistent lesion in these areas.

A 51-year-old promiscuous heterosexual man with no history of venereal diseases or porphyria had a large genital chancre and deep erosions on the hands. The HIV serology was positive; the CD4 lymphocyte count was 187/mm3, but the patient did not fulfill the CDC criteria for AIDS. Five months later he developed a clinical and biochemically typical porphyria cutanea tarda.

An epidemiologic study of the dermatophytoses in Salamanca (Spain) from 1973 to 1976 was performed. Dermatophyte species were identified in 224 patients with clinical tinea infections; 31 bovines, 18 rodents and 70 soil samples. The prevalence of Trichophyton verrucosum and Epidermophyton floccosum was strikingly high in relation to other statistics. The most common clinical forms were tinea corporis and tinea cruris. Tinea capitis by anthropophilic species was uncommon.
