A Rare Case of Eccrine Porocarcinoma of the Eyelid

Abstract

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.

Porocarcinoma; presentation and management, a meta-analysis of 453 cases

“…Mahomed and associates reported 5 cases of porocarcinoma with history of immune-compromised conditions, three of them were recipients of renal transplant and other two cases were the victims of acquired immune deficiency syndrome (AIDS) [29]. Owing to occurrence most commonly in sun exposed area (head, neck, hand, leg), some authors concluded that exposure to sun light is another risk factor [3], [5], [7], [10], [24]. In almost all cases, tissue biopsy was necessary for diagnosis in form of excisional, incisional and punch biopsy [21], [29].…”

Eccrine porocarcinoma of the head and neck: Meta‐analysis of 120 cases

“…The remaining 116 EPC cases of the head and neck from 90 studies were included in the meta‐analysis. The studies consist of 77 single case reports 7‐14,21,25‐93 and 13 case series with an average of three cases 20,23,24,94‐103 . Additionally, four EPC cases of the University Hospital of the Medical University of Vienna and Evangelical Hospital Vienna could be included in the meta‐analysis.…”
