Eccrine Porocarcinoma: A Case Report

Abstract

Eccrine porocarcinoma is an extremely rare malignancy of the eccrine sweat gland. It is believed to arise from the intra-epithelial portion of eccrine sweat glands. It can either arise de novo or it can develop in a long standing eccrine poroma. It often occurs in the elderly, with the mean age of occurrence being 67 years. The tumour favours extremities, particularly the legs and feet. The propensity to form multiple cutaneous metastases is an unusual feature of eccrine porocarcinoma. It is also associated with visceral metastasis, resulting in death. An early diagnosis and prompt treatment are thus essential, owing to the aggressive behaviour of the tumour. Keeping in view its rarity of occurrence, we are hereby presenting a case of eccrine porocarcinoma which occurred in a 55–year–old female.
