Abstract

introduction:Breast fibroadenoma in the axilla is a rare manifestation that consists of biphasic proliferation of fibromyxoid stroma without atypia or mitosis, with a glandular component consisting of two luminal and myoepithelial layers. In this study, breast fibroadenoma in the left axilla in a 45-year-old woman presented.

Case presentation: A 45-year-old woman complained of a lump in the left armpit and underwent a needle biopsy, but in the ultrasound and mammography examination, both breasts were normal and without lumps. In the pathology examination of the needle biopsy specimen of the axillary mass, biphasic proliferation of fibromyxoid stroma without atypia or mitosis was observed, along with a glandular component consisting of two layers of luminal and myoepithelial tuberculosis, and after the pathological examination of the surgical specimen, the diagnosis of fibroadenoma was confirmed. During the follow-up, the patient was alive and in good general condition after one year.

Conclusion:A careful examination of any swelling in the armpit area of a woman should be considered, because even though the main breast tissue is normal, it may be caused by benign or even malignant neoplasms from the accessory breast.
