[Juvenile secretory carcinoma of the breast. Apropos of a case in a 4-year-old girl].

The authors report the case of a juvenile secretory carcinoma of the breast in a 4 year old girl. The study of the first local excision leads to the thought of a "duct ectasia with a luminal benign papilloma". At the age of 6 years, there is a local relapse. A second local excision is performed and connected with simple mastectomy and an axillary node sampling. The pathological examination shows the aspect of a multifocal secretory juvenile carcinoma of the breast without lymph node axillary metastase. The authors emphasize the cystic appearance of the first tumor and the distinctive histologic pattern of this particular breast carcinoma.
