Simultaneous Occurrence of Balanoposthitis Circumscripta Plasmacellularis Zoon, Phimosis and in Situ Carcinoma of the Penis: Case Report with An Unusual Ulcerated Polypoid Variant of Zoon's Disease and a Carcinoma in Situ of Reserve Cell Type.

BACKGROUND

Zoon's balanitis is a benign disease characterized by an asymptomatic, chronic, solitary, shiny, red-orange plaque of the glans and/ or prepuce. In rare cases of Zoon's disease, penile squamous cell carcinoma developed in the chronic inflammatory lesions.

CASE REPORT: We report on a 68-year-old male patient presenting with phimosis and coexistent Zoon's disease and penile carcinoma in situ treated successfully by circumcision.

CONCLUSION

Coexistence of both lesions in contrast to the development of cancerous lesions within pre-existent Zoon's disease is a very rare observation.
