Eccrine porocarcinoma of the upper eyelid

Abstract
SUMMARY: A 75‐year‐old Caucasian man presented with foreign‐body‐type irritation of the left eye. Physical examination revealed a 12 × 10‐mm nodule in his left upper eyelid, which reportedly had been present unchanged for more than 40 years. No other ophthalmological abnormalities were present. Incisional biopsy of the lesion revealed a malignant tumour that was thought to possibly represent a sebaceous carcinoma. However, a subsequent wide surgical excision showed that the tumour was an eccrine porocarcinoma, a rare sweat gland adenocarcinoma arising from the acrosyringium.
