A rare case of primary carcinoma of axillary accessory breast tissue

Abstract

Carcinomas of primary accessory breast tissue are rare, comprising 0.3-0.6% of all breast cancers and occur most commonly in the axilla. We report the unusual case of a 50-year-old lady with mucinous adenocarcinoma of axillary accessory breast tissue. In this report we review the presentation, key investigations and treatment of this condition.
