Lactation from axillary breast tissue in the absence of a supernumerary nipple. A case report.

A case of lactation apparently from axillary supernumerary breast tissue was observed in a lactating woman. The tissue showed histologic features typical of both normal glands of lactation and apocrine sweat glands, and the fluid showed evidence of milk production. The supernumerary breast tissue was not associated with a nipple. Renal and skeletal anomalies were also noted.
