Patterns and trends of melanoma and skin carcinoma incidence and survival of European children (age 0-14 years) and adolescents (age 15-19 years) were investigated. Between 1978 and 1997, a total of 1419 melanoma and 485 skin carcinoma cases were recorded in the cancer registries contributing to the Automated Childhood Cancer Information System (ACCIS) study. During 1988-1997, the incidence of melanoma was 0.7 per million children and 12.9 per million adolescents; corresponding rates for skin carcinomas were 0.3 and 3.7 per million, respectively. The British Isles had the highest incidence of skin cancers in children and adolescents. For Europe, in adolescents melanomas were more common in the North and West, skin carcinomas in the South and East. Between 1978 and 1997 incidence increased annually in adolescents, by 4.1% for melanoma and 2.5% for skin carcinoma. Differences in aetiology between childhood and adolescent skin cancers cannot be excluded. Survival was relatively high and the geographical variations in incidence and survival seem to be associated.
