title: A case report of infiltrating ductal carcinoma originating from aberrant breast tissue.
abstract: We report a case of carcinoma originating from aberrant breast tissue in a 32-year-old female who had a soft subcutaneous mass on the anterior axillary fold. Histopathologic examination showed an infiltrating ductal carcinoma of aberrant breast tissue without metastasis to lymph nodes. We believe that subcutaneous nodules of uncertain origin around the periphery of the breast and especially in the axilla should always be viewed with suspicion and treated by early excision.
