Diagnosis: Extragenital lichen sclerosus

Description: Lichen sclerosus et atrophicus is a chronic inflammatory dermatosis of unknown etiopathogenesis predominantly affecting the anogenital areas and sometimes extragenital areas particularly of the trunk, neck, and upper limbs. It is ten times more common in women then men. It typically presents as small, porcelain white, sclerotic areas which may coalesce to larger patches and plaques. People with lichen sclerosus may have a personal or family history of other autoimmune disorders like thyroid disease, pernicious anemia, alopecia areata, and vitiligo.
