Eccrine porocarcinoma

Disease Overview

Eccrine porocarcinoma is a rare type of skin cancer that may occur by chance or may develop from a benign (non-cancerous) skin tumor. They affect the eccrine sweat glands, which are the major sweat glands of the body. Eccrine porocarcinoma usually are found in adults older than 60 and appear as a single red elevated solid mass (nodule) or a thickened or elevated lesion (plaque). They are found anywhere on the body, but occur most commonly on the lower limbs, head, and upper limbs.[12757][12758] Most people with an eccrine porocarcinoma do not have symptoms; however some individuals may notice bleeding from the tumor or itching.[12758] Factors that may increase the risk to develop an eccrine porocarcinoma include family history, suppression of the immune system, and exposure to ultraviolet light or radiation.[12759] Treatment usually involves surgery to remove the tumor.[12757]
