1 Invasive Ductal Carcinoma Arising from Axillary Accessory Breast Tae Wan Kim, Sang Wook Kang, Ji Young Park 2, Seung Sang Ko 1, Min Hee Hur 1, Hae Kyung Lee 1, Sung Soo Kang 1, and Jee Hyun Lee 1 Department of Surgery, Yonsei University College of Medicine, Departments of 1 Surgery and 2 Pathology, Samsung Cheil Medical Center, Sungkyunkwan University School of Medicine, Seoul, Korea As a consequence of the incomplete resolution of embryologic mammary ridges, ectopic breast tissue can be present anywhere along the "milk line", including the axillary region. Aberrant breast tissue can develop with any disease that affects the normal breast, including a breast carcinoma. A carcinoma of aberrant breast tissue is rare, but should still be investigated and treated properly with respect to other breast cancers in the embryonic milk-line. Herein is reported our recent experience of a carcinoma originating from aberrant breast tissue in the right axilla. An abnormal nodule around the periphery of the normal breast should be suspected as a breast carcinoma and differential diagnosis and properly treated.

Previously demonstrated right axillary tail located nodule is much enlarged in size with lobulated contour. And also dense lymph nodes are seen on right axilla. Left axillary focal increased parenchymal densities are also seen. Underlying diffuse increased parenchymal densities are seen on both breasts with nodularities. Both benign calcifications are seen. Others are unremarkable. Impression; Possibility of right axillary tail malignancy with axillary lymph node metastasis, suspected. 2. Both benign calcifications (Category 4-5). Fig. 4. Finding of ultrasonography. About mm sized lobulated hypoechoic nodule with inhomogenous internal echo is noted on right axilla. Two enlarged lymph nodes with cortical thickening, 16.7 mm and 9.3 mm, are noted on right axilla, level I. Others are not remarkable.
