The patient, a 55 years old farmer, noticed the pain of the knee joint and hydrops (sometimes bloody) 22 years ago, and operated 10 years ago in our clinic. It was partial synovectomy and then irradiation was additioned. The result of patho-histological study was proved to be PVS. But since immediately after discharge the nodule recurred and enlarged gradually.
10 years later the nodule grew to the size of fist and some other nodules was also recurred around the knee with diffuse tumorous swelling of synovium. Total synovectomy was done from both anterior and posterior approach. On patho-histological study there was proliferation of round synovial cells and histiocytic oval cells which contained the hemosiderin pigment. Multi-nucleated giant cells and foam cells were also found.
This case was PVS, we supposed, similar as Jaffe insisted.
Postoperative couse was regular, but we must observe it carefully from now on.
