[A case report of eccrine porocarcinoma]

Eccrine porocarcinoma (EPC) is a rare malignant skin appendage tumour deriving from the intraepithelial ductal parts of the sweat glands. First described by Pinkus e Mehregan nel 1963 as an epidermotropic eccrine carcinoma, it is rarely reported in medical literature and represents 0.005-0.01% of all skin tumors. We report a case of a 88-year-old Caucasian female presented to our Clinic with an asymptomatic, red-brown , irregularly shaped firm nodule on the left thigh aroused 15 years earlier. The lesion has been excised and histopathological examination showed an "eccrine porocarcinoma aroused on eccrine poroma". Review of the literature on this rare condition and possible therapeutic strategies are also discussed.
