[Synovial hemangioma of the knee-joint (author's transl)]

In monoarticular diseases of the knee-joint of children, especially in case of a blood-stained joint effusion, a synovial hemangioma has to be considered. The histological examination of an ample biopsy specimen can prove the diagnosis. A radical synovectomy carried out as early as possible results in healing of the lesion without recurrence.
