Polymastia is a term that is used to describe the presence of more than two breasts in human beings. It is synonymous with supernumerary or accessory breast tissue. In the ectopic breast tissue any disease can develop that affects the normal breast, including fibroadenoma. We reported a case of fibroadenoma of the axilla in a 23-year-old woman. Differential diagnosis of an axillary mass should also include fibroadenoma in an ectopic breast tissue.
