Eccrine porocarcinoma of the eyelid treated with Mohs micrographic surgery.
BACKGROUND
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.


OBJECTIVE
To discuss the clinical and histologic features and the prognosis of EPC.


METHODS
We report a 71-year-old man who presented with an asymptomatic lesion on his lower eyelid that had been present for 6 weeks.


RESULTS
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.


CONCLUSIONS
EPCs most commonly occur on the lower extremity. This case is interesting because the lesion was located on the lower eyelid.
