The distribution of lymph capillaries and blood capillaries in the synovial membrane was examined immunohistologically with anti–human collagen IV antibody and anti–human von Willebrand factor in 26 human temporomandibular joint (TMJ) samples comprising discs with adjoining synovial membrane from 10 control TMJs and from 16 TMJs with internal derangement. Three different distribution types were observed in the synovial membrane. In the control samples, the occurence of blood capillaries and lymph capillaries was rare. In mildly hyperplastic synovitis. lymph capillaries were observed just beneath the surface of the synovial membrane, whereas blood capillaries occurred in a little deeper layer of the synovia! membrane. In a severely hyperplastic synovitis. both lymph and Wood capillaries were observed frequently. The present results suggest that the different distribution patterns of lymph capillaries and blood capillaries reflect the degree of synovitis but can not be attributed to specific clinical symptoms.
