[Massive secondary psoriasiform dermatitis secondary to intravesical administration of mitomycin C]

We report on a patient who had been submitted to vesical diverticulectomy. Pathological examination of the surgical specimen revealed G2T1 urothelial carcinoma. Intravesical chemotherapy with mitomycin C was instituted. Following the sixth instillation, the patient developed widespread psoriasiform dermatitis and required admission to hospital. Remission was achieved with drug withdrawal and symptomatic treatment. The literature is reviewed.
