title: Juvenile secretory carcinoma and juvenile papillomatosis: diagnosis and treatment.
abstract: Carcinoma of the breast in the child is a rare pathologic entity, constitutes less than 1% of all breast lesions in this age group. The case of a girl with a left breast mass first noticed at 4.5 years of age is presented. An eccentric subareolar mass was excised at 6 years of age, sparing her breast bud. This biopsy contained juvenile secretory carcinoma, with additional pathologic changes characteristic of juvenile papillomatosis. Both the juvenile papillomatosis component as well as the juvenile secretory carcinoma component were devoid of estrogen and progesterone receptors in contrast to nondiseased breast tissue. The assay for these receptors was performed using a new antireceptor monoclonal antibody technique. Simple mastectomy was performed after completion excision demonstrated tumor at the pectoralis major fascia.
