Invasive Ductal Carcinoma of the Axillary Tail: Report of three Cases and Review of the Literature

Abstract

Axillary Breast cancer is a rare entity accounting for 0.12% of all breast cancer cases. It is typically composed of poorly differentiated IDC with occasionally areas of squamous or mesenchymal carcinoma [1]. Axillary malignancy is challenging as there are many differential diagnoses that may require careful evaluation process. The reported differential diagnoses are occult breast carcinoma, accessory breast cancer, axillary tail breast cancer, lymphoma or non-breast metastatic lymphadenopathy [2].
