Fibroadenoma is one of the most common benign breast disease seen in women in their late teens. Although ectopic benign breast tumour is more common along “Hughes line”, can also have an ectopic location., Whatever the position of ectopic breast tissue, it can undergo the same pathologic changes as seen in normally positioned breasts such as fibroadenoma and carcinoma., We report a case of fibroadenoma in unusual site, in 25year old female, who presented with painless swelling in the left infra-axillary region since 6months. It was diagnosed as fibroma or rare one fibroadenoma in axillary tail clinically., Fine needle aspiration cytology revealed benign fibro-epithelial lesion. The swelling was excised in toto and processed for histopathological examination. Histopathological examination confirmed fibroadenoma similar to the conventional type arising in the normal breast tissue.
