Introduction: Eccrine porocarcinoma is a rare skin neoplasm, origin of the eccrine sweat glands, which affects mainly elderly people. The clinical presentation is varied and the most common sites of occurrence are head and neck, followed by the lower extremities. Case report: Male patient, with 7cm nodular lesion in the right plantar region, of long evolution and that in the initial investigation presented lymph node metastasis. Radiotherapy was performed at the primary site and in the affected lymph node region. The surgery with curative intention was not performed, due to the metastases already present at the diagnosis. Discussion: The tumor does not have the well-defined etiology, but may arise as primary neoplasm or as malignant transformation of the eccrine poroma. The biopsy is the main diagnostic method and the tests for staging are necessary, whereas one-third of these tumors are metastatic. Wide-margin surgery is the treatment of choice and adjuvant therapies are reserved for recurrent and metastatic cases. Conclusion: The early diagnosis of the tumor is necessary to avoid that the therapy takes place in late phases and without curative proposals.
