Case Report of Malignant Eccrine Poroma on Lower Abdomen

ABSTRACT

Malignant eccrine poroma is a rare malignant tumor that arises from the intraepithelial ductal portion of the eccrine sweat gland. It may be developed either spontaneously or from a preexisting benign eccrine poroma. We report a case of malignant eccrine poroma on right lower abdomen in a 78-years-old female, which has been present for 1 year. In our case the tumor demonstrated without local invasion and distant metastasis, and was successfully removed by surgery.
