Vulvar Pityriasis Versicolor in an Immunocompetent Woman

Abstract

To report a case of isolated vulvar pityriasis versicolor in a 24-year-old healthy woman. A 24-year-old woman presented with variable color change on the vulva of 8 months in duration. Areas of tan and white skin were observed on the mons pubis. The pubic hair had been shaved. Initially, the paler areas were deemed abnormal suggesting vitiligo, but the biopsy showed normal skin including normal numbers of melanocytes. Subsequently, biopsy of the tan area showed pityriasis versicolor. She was successfully treated with topical 2% ketoconazole, with gradual fading of lesions. With increased body awareness and the current popularity of pubic hair removal, young women may consult clinicians about color changes on the vulva. Clinicians should be aware that vulvar pityriasis versicolor may occur in healthy women with no other skin involvement.
