Carcinoma arising from ectopic breast tissue, either supernumerary breast or aberrant breast tissue, is extremely rare. Carcinoma occurs more frequently in the ectopic breast tissue of the axilla than in extra-axillary ectopic breast tissue. Here we report a case of an invasive lobular carcinoma arising from extra-axillary ectopic breast tissue and presenting as a subcutaneous nodule.
