[A case of prostatic cancer associated with von Recklinghausen's disease].

A case of a 65-year-old man with prostatic cancer associated with von Recklinghausen's disease ( VRD ) is reported. The coexistence of neural crest malignancies with VRD is well known. Recently, it has been reported that non-neural crest malignancies appear to occur with increased frequency in patients with VRD . The non-neural crest malignancies now known to be associated with VRD are Wilms' tumor, non-lymphocytic leukemia, rhabdomyosarcoma, and others. The relationship between VRD and non-neural crest malignancy (including carcinoma) is reviewed and briefly discussed.
