Eccrine porocarcinoma is a rare skin adnexal malignant neoplasm that may arise from a pre-existing benign eccrine poroma or without a predisposing factor. It is a highly invasive neoplasm and has a strong metastatic potential. The most frequently affected organs are the lymph nodes and rarely solid organs such as the liver, lungs and breast. We report a case of a woman with a history of surgically treated eccrine porocarcinoma that a year later presented with multiple lesions in both breasts and axillary lymphadenopathies. After a detailed imaging investigation, the diagnosis of metastatic lesions from porocarcinoma was made. To our knowledge, until the moment, only one case of breast metastasis of eccrine porocarcinoma has been reported in the literature.
