[The tumorous form of bladder malacoplakia. Apropos of 2 cases]

The authors report two rare cases of neoplastic vesical malakoplakia, one with an enterovesical fistula and the other with extravesical pelvic extension. The symptoms are non-specific and the diagnosis remains histological. Medical treatment, based on the suspected infectious physiopathogenesis of the disease, consists of variable combinations of antibiotics, cholinergics and vitamin C. It must be sufficiently prolonged and conservative in view of its usual efficacy, even in neoplastic forms.
