“…2 It occurs in 0.4% to 6% of the population, with the axilla being the most common location. 3 The tissue is hormone responsive, and therefore may increase in size and present during puberty, pregnancy, or lactation. Management is typically conservative, but surgical excision can be considered for cosmetic reasons or if persistent.…”

“…Mostly they are appearing at the embryonic mammary ridge (milk line). The embryonic mammary ridge is extending from the axilla to the groin; it mostly occurs without a nipple and areola, and although commonly asymptomatic, it may manifest symptoms during pregnancy, menstruation, or lactation due to hormonal changes 1 , 2 . Most commonly, EBT can be seen in the axilla; however, it has also been reported in the valva, chest, hip, shoulder, neck, thigh, perineum, upper extremities, and middle back, including the facial region 1 .…”

Introduction: 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.

“…Ectopic breast tissue (EBT) is an uncommon entity that occurs in about 0.2%–6% of the population ( 1 , 2 ). EBT is an embryological abnormality that results from involutional failure of the mammary ridge, commonly referred to as the milk line ( 3 ). The milk line starts from the axilla and extends inferior to the groin, leading to the possibility of EBT along this axis.…”

Ectopic Breast Tissue in the Inguinal Region: A Case Report and Suggestion of Indications for Excision

We report a rare case of ectopic breast tissue situated in a unique location. A 50-year-old female patient came to our institution complaining of a bulge in the inguinal area. CT was unremarkable other than a benign-looking conglomeration of lymph nodes around the inguinal canal. However, excisional biopsy proved otherwise, with strong expression of breast-related immunohistochemical markers on pathology. Based on histological findings, the diagnosis of ectopic breast tissue was made. Since the vast majority of ectopic breast tissue is found around the breast mound, axilla, and along the milk line, this case is peculiar in its location. This report shares our experience and provides indications for excision of incidental ectopic breast tissue.
