Intra-abdominal ectopic breast tissue in male patient presenting as a fibroadenoma: a case report

Fibroadenoma (FA) in ectopic male breast tissue is extremely rare. The ectopic breast tissue (EBT) is mostly appearing along the milk line; however, uncommon locations are also seen, such as the present case. CASE PRESENTATION: The authors report a 19-year-old male presenting with intestinal obstruction. The patient underwent laparoscopic surgery, and an excisional biopsy of the lesion was done. The histopathologic result confirms FA arising from EBT. This case is reported for its rarity. It indicates that FA should always be considered when there is an intra-abdominal suspicious mass. DISCUSSION: EBT presenting as FA is also reported in the face, posterior neck, chest, middle back, buttocks, vulvar, and thighs. In this case, the authors present a EBT presented as a FA in the intra-abdomen of a young male patient, causing intestinal obstruction. FA in the male breast is rare; however, benign breast parenchyma showing FA in the intra-abdomen of a male patient is extremely rare. CONCLUSION: When a tumor is palpated in the milk line, the existence of FA should be taken into consideration. FA of the male EBT in the intra-abdomen is extremely rare. However, a close follow-up of the patient is strongly recommended, as the carcinoma arising from FA has a very poor prognosis.
