Basal cell carcinoma in a girl after cobalt irradiation to the cranium for acute lymphoblastic leukemia: case report and literature review.

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.

Diffuse whitening of the oral mucosa in a child.

We report a healthy 16-year-old Caucasian boy, who consulted us for white, asymptomatic lesions in the mouth. The lesions were stable and had been present for 6 years. On physical examination, there were diffuse white, soft, corrugated plaques involving the buccal and labial mucosa, oral commissures, and floor of the mouth. No other mucosae were affected and there were no skin or nail abnormalities. The histologic findings revealed epidermal hyperplasia with parakeratosis and intracellular edema in the squamous cell layer. No nuclear atypia was observed. A differential diagnosis of three entities is proposed: white sponge nevus, leukoedema, and focal epithelial hyperplasia.
