Bilateral fibroadenoma and gynecomastia in a young male: sequential or concurrent diseases: case report

Abstract

In this case report of bilateral fibroadenomas of the breast in a 17-year-old male, we add to the relatively small number of reported cases. Initially assumed to be HAART-associated gynecomastia, our patient with congenital HIV, had normal hormone levels and was otherwise of normal secondary sexual development, except for an uncomplicated undescended testis. The conjunction of clinical finding, imaging and histological finding confirmed a fibroadenoma with gynecomastia. Only a small number of bilateral fibroadenoma in male have been reported in the literature. The finding of co-occurring gynecomastia strengthens the argument for gynecomastia as a necessary prerequisite for the development of fibroadenoma in male due to the quasi inexistent glandular tissue in a normal male breast (the so called sequential theory). The finding suggest that despite the scarcity of fibroadenoma in male, this condition can still be found in the spectrum of male breast pathologies.
