Lichen planus (LP) is an inflammatory dermatosis which can affect the skin, nails, and all mucous membranes, including the genitalia. Lichen planus on vulvar keratinized skin can manifest with diverse clinical features, probably due to higher temperature, PH, humidity, and bacterial flora which may modify typical cutaneous features. While lichen planus (LP) may affect the vulva in isolation, it may also be part of generalized outbreak in up to 20% cases. Herein, a case of a 53 year-old female who presented with a severely pruritic plaque over labia majora Since 6 -7 months, with no response to potent topical corticosteroids is reported. Provisional diagnosis of lichen simplex chronicus was considered however, histopathology was suggestive of hypertrophic lichen planus.
