Breast cancer on a scar of excision of ectopic breast tissue: A case report

The cancerization of supernumerary breast is uncommon. So when this situation occurs, the diagnosis is often late. Cancers of ectopic breast tissue have been reported in the international literature, but to our knowledge, no cancer after excision of accessory breast gland has been published. This article describes a case of ectopic breast tissue cancer in axillary situation occurring several years after excision and details its specific diagnostic, therapeutic and prognosis. © 2011 Elsevier Masson SAS.
