Examples
vulvar hidradenoma papilliferum
- Hidradenoma papilliferum is a benign apocrine lesion found almost exclusively in women, most often the labia majora. It forms a well-circumscribed dermal nodule with papillary projections with a fibrous stroma.
- They are lined with a double-layered epithelium composed of inner cuboidal myoepithelial cells and outer columnar cells with eosinophilic cytoplasm.
- The outer cells may demonstrate decapitation secretion, in which the apical portion of the outer cells pinch off; this feature is frequently observed in apocrine lesions.
