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

Uwe Wollina et al. Open Access Maced J Med Sci. .

Abstract

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.

Keywords: Balanitis plasmacellularis Zoon; Carcinoma in situ; Circumcision; HPV; Morbus Queyrat; Penile cancer; Pimosis.
