Malignant eccrine poroma


Malignant eccrine poroma is a rare skin appen­dageal tumor occurring on the intraepidermal ductal portion of eccrine sweat glands. It was initially described as epidermotrophic eccrine carcinoma by Pinkus and Mehregan in 1963. In 1969, Mishima and Morioka2 used the term, eccrine porocarcinoma, subdividing the malignant form of benign eccrine poroma into poroacanthoma, poroepithelioma and porocarcinoma by a degree of differentiation. Although about 120 cases have been reported so far, the incidence and clinical aspects of malignant eccrine poroma have not yet been identified yet. Malignant eccrine poroma is known to develop on the lower limbs of the aged and sometimes metastasize to regional lymph nodes and internal organs, causing fatal consequences.
