Eccrine Porocarcinoma of the Eyelid Treated With Mohs Micrographic Surgery

Abstract
Eccrine porocarcinoma (EPC) is a rare malignant tumor of the eccrine sweat glands. The lesions are reported to occur most commonly on the lower extremity with variable prognosis. To discuss the clinical and histologic features and the prognosis of EPC. We report a 71-year-old man who presented with an asymptomatic lesion on his lower eyelid that had been present for 6 weeks. The 4 x 4-mm lesion was removed in two stages using the Mohs micrographic surgery fresh-tissue technique. The histopathologic diagnosis was primary EPC. EPCs most commonly occur on the lower extremity. This case is interesting because the lesion was located on the lower eyelid.
