Plasma cell balanitis and vulvitis (of Zoon). A study of 10 cases.J Reprod Med. 1994 Dec; 39(12):939-44.JR
We report six cases of plasma cell balanitis and four of plasma cell vulvitis. The patients' ages ranged from 26-88 years in males and 30-60 in females. All the men were uncircumcised and presented with a discharge and erythematous lesions on the glans penis and prepuce. In females the main presenting complaints were vulvar soreness, pruritus, smarting/burning, discharge and bleeding. Two were on hormone replacement therapy, two had undergone a mastectomy for carcinoma of the breast, and one was an insulin-dependent diabetic. Another patient subsequently developed diabetes mellitus. Topical and intralesional corticosteroid preparations resulted in satisfactory improvements in all cases, male and female. Two males subsequently underwent circumcision, which was curative.
