Patients with axillary lumps undergo thorough examinations and investigations to rule out malignancy, particularly in women, where many are associated with breast cancer metastasizing to lymph nodes. Supernumerary breast tissue harbouring a lump poses a rare but heightened risk of cancer, while in regions like India, tuberculosis should also be considered. Benign conditions like fibroadenomas in ectopic breast tissue are even rarer. Hence, any axillary lump case warrants consideration of these possibilities. We present a rare case of a young female with a solitary lump in ectopic breast tissue, initially resembling an axillary lymph node on imaging but later diagnosed via fine needle aspiration cytology (FNAC) as a fibroadenoma.
