Eccrine porocarcinoma is a rare malignant sweat gland tumor. The lower extremity represents the most common tumor site for this entity. Surgical excision seems to be the best treatment choice. The surgical margins should be free of tumor, otherwise a local recurrence is most likely. Regional lymph node dissection should be performed if there is evidence of lymphadenopathy. Here, we present clinical and pathological findings of a 69 years old woman diagnosed with eccrine porocarcinoma arising from the skin of the trunk.
