Occupational traumatic lymphedema of the hands.

Secrétan's syndrome is characterized by hard persistent edema of the dorsum of the hands. Usually, the condition is self-inflicted, but the authors have seen four cases that were occupationally related. The patients were fishing divers, and the mechanism appeared to be the constrictive action of the tight diver suit and pricks from sea urchin spines. Lymphographic abnormalities were present in one case.
