[Severe algoneurodystrophy of the right foot associated with prostatic cancer].

The authors report 1 case of particularly severe reflex neurovascular dystrophy whose clinical course was marked by the discovery of a carcinoma of the prostate. There was improvement in the reflex neurovascular dystrophy despite hormonal therapy of the cancer. Reflex neurovascular dystrophy cannot be considered as a form of a paraneoplastic syndrome.
