Thrombophlebitis commonly occurs in Bchcet disease and causes various symptoms. It is, however, very rare that a thrombosis causes nerve palsy. A case of brachial plexus palsy due to compression by venous thrombosis in the axillar area is reported. A 40-year - old man has been afflicted with Bghcet disease since 1982. He had a few month's history of a radiating pain and numbness on his left arm down to his fingers. Examination revealed a soft and egg-sized tumor in the left axilla. Tinel's sign was positive. Total resectioning of the tumor was done. The tumor was 20×20mm in size and connected to a branch of the axillar vein.
The Brachial plexus was directly compressed by the tumor. Histological examination proved this tumorous condition to be an intravenous thrombosis.
