Upper limb reflex sympathetic dystrophy associated with occult malignancy.
Reflex sympathetic dystrophy, characterized by pain, swelling, vasomotor instability, and trophic changes in an extremity, has been infrequently described in patients with occult malignancy. Two cases of reflex sympathetic dystrophy associated with local tumor involvement are reported. Both patients had a history of cancer in clinical remission. Despite aggressive physical therapy measures, the patients' symptoms persisted. Workup of the first patient found an apical paravertebral mass in the lung; biopsy revealed recurrent breast carcinoma. In the second case, workup found an axillary mass contiguous with the lower brachial plexus. Biopsy revealed lymphoma, a second primary malignancy. In both cases, medical treatment of the tumor was instituted, with consequent improvement of hand and shoulder function. Both patients required prolonged hospitalization and multiple procedures that might have been avoided if malignancy had been suspected. Spontaneous development of reflex sympathetic dystrophy in patients with a history of cancer should alert the physician to the possibility of occult malignancy.
