Atypical eccrine poroma of the buttock: Expanding the clinical spectrum of a rare benign neoplasm

Year: 2025

Type: article

Abstract: Eccrine poromas are benign adnexal neoplasms that typically arise on acral skin, particularly the palms and soles, where eccrine sweat glands are most concentrated.1 Although the classic presentation is acral, poromas have been reported on nonacral locations.1,2 Atypical clinical and histopathologic morphologies can add a diagnostic challenge to such cases. Here we present a rare case of an eccrine poroma with atypical features located on the buttock, an uncommon site for this tumor, and highlight the diagnostic considerations when evaluating these tumors.
