Fine needle aspiration cytology of supernumerary breasts. Report of three cases

Fine needle aspiration (FNA) was performed on small lumps in three female patients in the reproductive age group. One lump in the axilla and one on the chest wall were clinically suspected of being a lipoma or an angioma while another axillary lump was thought to be an enlarged lymph node. Cytologically, the aspirates revealed the presence of ectopic breast tissue. These cases show yet another instance in which FNA cytology can make the diagnosis of lumps of unknown origin, avoiding the need for open biopsy.
