[Giant juvenile fibroadenoma in an adolescent. A case report].

Fibroadenomas occupy the first place, in terms of prevalence, among benign breast disorders in adolescent girls. Juvenile giant fibroadenoma is a special though rare form, which must be recognised in terms of differential diagnosis from virginal hyperplasia in its asymmetrical early form and phylloid tumours, the prognosis of which is different. The authors describe the clinical and pathological features necessary for diagnosis and report the results of breast reconstruction after excision via a lateral radial approach in a 14-year-old adolescent girl.
