Abstract
A 32 year old female patient with a soft boggy mass in the left axilla was referred from the surgery clinic for fine needle aspiration with a provisional diagnosis of fat hypertrophy. Physical examination revealed a well defined mobile nodule within the mass. Cytological examination of the aspirated material and histopathological examination was consistent with fibroadenoma.

Summary
Supernumerary breast and ectopic breast occurs in 1-6% of the general population. Ectopic breast tissue (EBT) occurs along the milk lines, extending from the mid axilla to the medial groins [1]. The embryological analogue of the milk line is the milk ridge, which later undergoes complete atrophy except for short segments that remain in the pectoral region to give rise to normal breasts. Ectopic or supernumerary breast develop from portions of the milk ridges that fail to atrophy. Ectopic breast tissue shows pathologic changes similar to normally positioned breast and is a marker of urologic malformations or urogenital malignancies [2]. Though ectopic breast tissue has been reported but a fibroadenoma developing in EBT is a rare entity. We report a case of 32 year old woman with a fibroadenoma in ectopic breast tissue in axilla
