Abstract

Background: Plasma cell vulvitis, or Zoon’s vulvitis, is a rare, benign, idiopathic, chronic inflammatory condition that affects the vulva. In 1952, Zoon reported a histological plasmacytic infiltrate, called balanitis plasma cellularis, which affected the penis and prepuce. Similar lesions identified in the vulva were reported by Garnier in 1954 and described as Zoon’s vulvitis. Case reports of this condition are rarely described in literature.
