Background: Ectopic breast tissues may be affected by the same physiological and pathological alterations seen in the normal breast, including fibroadenoma. Since valid studies describing this anomaly are rare, we decided to report a case of fibroadenoma in axillary breast tissue. We report a 28-year-old nulliparous woman presented with a left axillary lump, for which clinical impression of axillary lymphadenopathy was made for two months. After surgical resection of the nodule, the histology was identical to the fibroadenoma seen in the ectopic breast tissue.
The histopathology was identical to the fibroadenomas seen in the ectopic breast tissue and those observed along the milk line. Therefore, fibroadenoma in an ectopic breast tissue must be kept in mind in the differential diagnosis of axillary mass.
