Hidradenoma Papilliferum : Intro & Clinical - WebPatholog

Introduction: Hidradenoma papilliferum (Papillary Hidradenoma) is an uncommon benign adnexal tumor that shows both apocrine and eccrine differentiation. It is found almost exclusively in the vulva HP is characterized by a complex network of branching papillae (above). The papillae are lined by two cell layers: an outer layer of myoepithelial cells and an inner (luminal) layer of cuboidal cells. Decapitation secretion is often present. slide 68 of 12 As illustrated above, HP is a well-delineated dermal lesion composed of arborizing papillae with scattered gland formation. On rare occasions, there have been reports of ductal carcinoma in-situ arising within HP. slide 67 of 12

Two-layered epithelium, including p63-positive myoepithelial cells supports the diagnosis of hidradenoma papilliferum and rules out malignancy.

Comments: Some cases may show a varied appearance throughout the lesion. In the photomicrograph above, some of the cells (right) show marked apocrine changes. These cells contain abundant, pink cytoplasm and prominent apical snouts

Cooper and Mac Donald, in 1944, described the first case of perianal hidradenoma papilliferum 2; since then, less than 20 cases have been.

Hidradenoma papilliferum (HP) is an uncommon benign tumour that is located mostly in the vulva and less often in the anal area.1 2 They occur most often in middle-aged Caucasian women.1 2 The histopathology demonstrates branching and anastomosing tubules that are composed of columnar cells with focal decapitation secretion and cuboidal myoepithelial cells.3 The cells demonstrate.
