A peculiar anatomoclinic form is described about the Balanoposthite chronique circonscrite bénigne à plasmocytes (Zoon): the pimpled, erosive, nodular and pseudoangiomatous form. Clinically this balantis realizes a pseudo-oedematous infiltration (which belongs to the usual form) and especially botriomycome-like nodules (obs. 2) or pseudo-neoplastic tumors (obs. 1). Histologically, the lesions consist of a pure plasmocytar infiltration, with total disappearance of the epithelium. In spite of its pseudo-tumoral aspect and of the abundance of plasmocytes, this kind of balanitis is quite benign and chronic, may persist many years without transformation, and is never a sign of dysglobulinemia.
