A Rare Case of Eccrine Porocarcinoma of the Eyelid

Abstract

Background: To report a rare case of eyelid eccrine porocarcinoma and compare this to previous documented cases in the literature. Main Observations: We report a case of an 86-year-old man who presented with three months’ history of irritation in the right eye, who was found to have an irregular nodule on lower eyelid, which was later diagnosed as eccrine porocarcinoma (EPC). The lesion was excised and the defect repaired with Hughes flap. A computerized tomography (CT) scan of the head, neck, and chest showed no metastasis and no lymphadenopathy. There was no evidence of recurrence after 18 months of follow-up. Conclusion: To date, there have been only six cases of eyelid EPC reported in the literature. EPC has significant risk of recurrence and metastases after local excision. It is therefore important to consider it in the differential diagnosis of malignant eyelid tumour. A histological diagnosis should prompt wide margin excision, assessment of the patient for regional lymph node involvement, and imaging for metastatic disease.
