title: Melanoma in childhood and adolescence: clinical and pathological features of 48 cases.
abstract: Forty-eight cases of melanoma occurring in patients under 20 years of age were reviewed from a 23-year period at a single center. Fourteen of the patients were preadolescent children and 44 were Caucasian. Histological review of 44 available primary tumors showed only superficial spreading and nodular types. Thickness ranged from 0.23 mm to 8.50 mm, with a median of 1.03 mm. Ulceration was present in 7%, necrosis in 35%, evidence of regression in 16%, and antecedent nevus in 49% of the cases. The overall 5-year survival is 77%, with a median follow-up of 48 months. There is no detectable survival difference between preadolescent children and adolescents. Several treatment failures occurred after improper biopsy and/or inaccurate original diagnosis of Spitz's nevus. Of 38 stage I and II patients given definitive surgical treatment by the authors, the 5-year survival is 90%. Although histological confusion with Spitz's nevi occasionally occurs, melanoma in this age group can be treated with good results.
