[Carpal tunnel syndrome due to mycobacterium bovis BCG (author's transl)].

A 45-year-old woman, previously in good health developed chronic tenosynovitis with carpal tunnel syndrome a few weeks after wounding herself with a Pasteur pipette containing BCG cultures. She had received two injections of triamcinolone in the anterior annular ligament of the right carpa. The patient recovered after twelve months of antituberculous therapy associating isoniazid (300 mg/day), ethambutol (800 g/day), and rifampicine (400 mg/day). This is the first report of BCG tenosynovitis of the hand. The hazards of steroid injections into the tendon sheaths are pointed out.
