Hidradenoma poroide: reporte de dos casos y revisión de la literatura

Poroid hidradenoma (PH) is a benign dermal tumor that is part of the structural classification of poromas and represents only 5% of them. There are 172 reports of PH in the literature in Spanish and English, of which 51% correspond to female patients and only 10% to an upper extremity topography. Diagnosis is made through histopathology; the findings are poroid cells and cystic components at the dermal level without connection to the epidermis. The definitive management is surgical; PH presents very low recurrence rates and a malignancy percentage of 1%. We report the first two cases of PH in Mexico, one of them in an unusual topography.
