Pigmented Poroid Hidradenoma: A Case Report.
Poroid hidradenoma (PH) is an infrequently encountered benign adnexal neoplasm exhibiting eccrine differentiation. Histopathologically, PH displays a distinctive combination of hidradenoma-like architectural organization characterized by a purely intradermal localization with both solid and cystic components, and cytological attributes of poroid neoplasms, consisting predominantly of poroid and cuticular cells. In the present report, we document a case of pigmented PH arising on the thigh of a 44-year-old male patient and discuss its characteristics and clinical course.
