Porocarcinoma of the eyelid

Purpose: The purpose of this report is to describe the clinical and histopathologic findings in a patient with porocarcinoma of the eyelid. Methods: The case of a 68-year-old woman with a nodular lesion of the eyelid was studied, and the pertinent literature reviewed. Results: No previous description of porocarcinoma of the eyelid was found in the literature. The present case presented with a nodular lesion of the right lower eyelid of 1-year duration. The tumor was completely excised. Microscopic study revealed ductal structures within lobules of tumor cells. Conclusions: Porocarcinoma is a rare cutaneous adnexal tumor arising from the eccrine secretory apparatus. Because the clinical behavior of this cancer includes deep invasion, regional lymphatic spread, and distant metastases, complete surgical excision is recommended, and should be verified by either conventional frozen sections or Mohs' micrographic sections.
