Porocarcinoma is a malignant tumor arising from intraepidermal eccrine duct epithelium or acrosyringium with an aggressive course. Sites of predilection include lower extremities (50%), trunk (24%), and head and neck (24%), while it is uncommon in the upper extremities and genitals. We report a case of eccrine porocarcinoma in the axillary region with axillary lymph node involvement and pulmonary metastasis in a 78-year-old male.
