Discussion Plasma Cell balanitis (PCB) or âbalanitis circumscripta plasma cellularisâ is a benign, idiopathic condition first recognized by Zoon in 1952. Zoon described eight cases of chronic balanitis with unique benign appearing histologic findings previously diagnosed as Erythroplasia of Queyrat [1-3].he etiology of this disease is unknown. This balanitis does not respond to routine topical antifungals, steroid creams and systemic antifungals. Diagnosis is confirmed by biopsy. Herein we report 8 cases of PCB, presenting with a characteristic clinical picture of the disease.
