Plasma cell balanitis of Zoon: response to Trimovate cream.

Our objective was to evaluate the response to Trimovate cream in patients with Zoon's balanitis. Patients attending the penile dermatosis clinic between October 1996 and October 1999 with the clinical and histological features diagnostic of Zoon's balanitis were included in this study. They were treated with Trimovate cream for a varying length of time according to clinical response, having declined circumcision as first-line treatment. All cases had photographs taken before and after treatment. Ten cases of histologically-confirmed Zoon's balanitis were treated. Clinical resolution was observed in all cases, all of whom remain on long-term follow-up. In conclusion, topical Trimovate cream is an effective treatment for Zoon's balanitis.
