tumors of labia majora

Monday 8 April 2019

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.
