Question: What are the benign pigmentary lesions of the vulva?

Answer:

  1. Melanocytic nevi: Vary in color and size (from 1-2 mm to 1-2 cm). Typically are asymptomatic. Diagnosis confirmed histologically usually with simple excision.
  2. Acanthosis nigricans: Cutaneous disorder affecting the axillae, nipples, umbilical area, and crural region. Appears as a poorly defined, velvety hyperpigmentation. Only symptomatic treatment is available.
  3. Vitiligo: Characterized by complete depigmentation of an area of skin that is otherwise normal. The area involved is usually well defined and symmetrical. No effective treatment is available.
