Sclerosing Adenosis in Axillary Supernumerary Breast: A Case Report

ABSTRACT

Swellings in the axilla especially in women are always viewed with suspicion owing to a large number of these being associated with breast carcinoma presenting as nodal metastasis. In a country like India, tuberculous lymphadenopathy is also amongst the first differentials. We present a case of a woman with left sided axillary swelling which on Fine Needle Aspiration Cytology (FNAC) turned out to be sclerosing adenosis of the accessory axillary breast. Accessory breasts may present as asymptomatic masses or cause symptoms such as pain or restriction of arm movements. Both benign and malignant tumors can arise in accessory breasts. So far cases of fibroadenoma and carcinoma breast have been reported but sclerosing adenosis has never been reported. Accessory breasts as mass in the axilla may prove to be a diagnostic challenge for surgeon. FNAC being an easy and accurate technique can be very helpful in differentiating such lesions.
