Axillary fibroadenoma: Case report and review of literature

Abstract

Fibroadenoma of breast and ectopic breast tissue is common pathology. Sometimes, it may be associated with hormonal imbalance. However, the presence of fibroadenoma in the axilla without ectopic breast tissue and hormonal imbalance is a rare presentation. We are presenting a rare case report of fibroadenoma developing in the right axilla in a 28-year-old woman. Clinical examination of both breasts revealed no abnormalities and no lymph nodes or supernumerary breasts were detected in the axilla or the neck. No associated urologic or cardiovascular abnormalities were found and the histopathological examination of the excisional biopsy samples showed a well-defined, capsulated type of fibroadenoma similar to that of ectopic mammary tissue.
