Eccrine Porocarcinoma

Eccrine porocarcinoma is an extremely rare malignant cutaneous neoplasm. This tumour has an indolent behavior and misleading clinical diagnosis often leading to a delay in definitive treatment. The definitive diagnosis is made by histopathology since clinical findings often vary. The tumour must be considered in the differential diagnosis of elderly patients presenting with long standing skin lesion with a recent history of accelerated growth rate. Because of its reported high rate of local recurrence, a wide excision of the tumour with clear resection margins is mandatory. Close long term follow up is required. We present herein two cases of eccrine porocarcinoma.
