Three Adnexal Tumors in a Single Lesion: A Case Report
AbstractEccrine poroma is a benign tumor originating from the epidermal sweat duct unitis. Malignant transformation may occur in these lesions, and symptoms of bleeding, pain, and pruritus suggest potential malignancy. Common sites of involvement include plantar, palmar, and acral skin, but eccrine poromas may occur in any skin surface area with sweat glands. Hidroacanthoma simplex, eccrine poroma, dermal duct tumor and poroid hidradenoma are four histopathologic types of poroma or poroid neoplasms. Some authors have reported a combination of two or three of these tumors in a single lesion. As far as we know, the overlapping ecrine ductal tumor that covers eccrine poroma(EP), dermal duct tumor(DDT), and eccrine hidradenoma(EH)] has not been reported in the literature. The aim of this report is to present this rare case.
