Fibroadenoma of the Axilla in A Patient With Macroprolactinoma

Abstract

Ectopic breast tissues may be affected by to the same physiological and pathological alterations seen in the normal breast, including fibroadenoma. We report a 30-year-old nulliparous woman who presented with a left axillary lump, for which clinical impression of axillary lymphadenopathy was made. She was receiving treatment with cabergoline due to a prolactinoma with galactorrhea for some years, but her serum prolactin levels were still high. The patient underwent surgical resection of the nodule and the histology was identical to the fibroadenomas seen in the breast. To the best of our knowledge, this is the first report of fibroadenoma of the axilla in a patient with a macroprolactinoma. fibroadenoma in an ectopic breast tissue must be kept in mind in the differential diagnosis of axillary mass.
