[Tuberculous bilocular cystic hygromas of the right hand and forearm].

A rare complication of bone tuberculosis is bicameral hygroma of the hand and forearm. The transverse separation is caused by the retinaculum flexorum. Tendons can be destroyed by inflammatory changes of the synovial fluid. Experience with the few patients treated so far suggests that total extirpation combined with tuberculostatic therapy is necessary for the attainment of a cure.
