  • Pigmented villonodular synovitis is a rare proliferating process of the synovium, tendon sheaths and bursae usually affecting the bone and joints. The disease can be localized or diffuse. Patients with this condition typically present with symptoms of mild discomfort and associated swelling of the involved joint. However, the spectrum of presentations is broad. Diagnosis of Pigmented villonodular synovitis can be clinically difficult, and plain radiographs are usually nonspecific. Magnetic resonance imaging is a highly diagnostic modality in characterizing pigmented villonodular synovitis when it contains hemosiderin deposits exhibiting low signal intensity on all pulse sequences. Magnetic resonance imaging is recommended for accurate preoperative staging of the disease and for follow up after treatment. I report a case of pigmented nodular synovitis in the knee joint, with review of literatures.

  • Pigmented villonodular synovitis(PVNS) is a benign proliferative lesion, involving synovial tissue in joints, tendon sheaths, and bursae. Pigmented villonodular synovitis is a rare and usually monoarticular condition and primarily affects the knee joint and hand. Polyarticular PVNS appears in less than 1% of all case and its occurrence in the shoulder is rare(<2%). We present a 64-year-old male who had pigmented villonodular synovitis of both shoulder joints, which was treated by arthroscopic total synovectomy.

  • Pigmented villonodular synovitis is a destructive, fibrohistiocytic proliferation producing innumerable villous and nodular synovial protrusions. Its common locations are knee, ankle, foot, and hip. Although histologic feature of this tumor is well known, there have been few reports on the fine needle aspiration cytology findings. We report the cytologic features of a biopsy-proven case oi pigmented villonodular synovitis. The patient was a 21-year-old male with a mass of the right knee for 2 years. On fine needle aspiration cytology, the aspirates was composed of abundant mononuclear histiocytic cells, singly and in clusters, multinucleated slant cells, and hemoslderin pigments.

  • Pigmented villonodular synovitis (PVNS) is a rare proliferative disease affecting joint synovium, tendon sheaths, bursae. The usual treatment for PVNS is a surgical excision. If destructive joint lesions have occurred, complete resections must be performed followed by arthrodesis or arthroplasty. We report a case of a pigmented villonodular synovitis involving an ankle joint which was treated by total ankle replacement for recurrence after simple synovectomy.

  • Villonodular synovitis, also called pigmented villonodular synovitis, is the benign lesion with the characteristic of locally aggressive proliferation of mononuclear histiocyte and giant cell. Typically it involves single joint, especially about 80% of disease occurs in the knee joint. Villonodular synovitis of the temporomandibular joint is very rare disease. Differential diagnosis includes synovial chondromatosis and tumors of the temporomandibular joint. Optimal treatment consists of complete excision of the mass and removal of the synovium including adjacent affected bony structures. This is a case report of villonodular synovitis developed in the temporomandibular joint.

  • Pigmented villonodular synovitis most commonly occurs in the knee joint and rarely extends into the popliteal space, which not only has mimicked Baker's cyst but also has been misdiagnosed as malignant tumor. We report a case of a diffuse pigmented villonodular synovitis of knee joint which is extended into the popliteal space as like a popliteal cyst. We treated this case by arthroscopic total synovectomy and excision of cyst. There was no recurrence during more than one year after operation.

  • Hemangioma are not rare tumors. They can be found in almost any of the vascular structures of the body. Hemangiomas involving the deep structures of the extremities may produce extremely difficult therapeutic problems for the orthopedic surgeon. Pigmented villonodular synovitis (PVNS) is a rare proliferative disorder that affects synovium, tendon sheath and bursa. Although the condition can present in any joint, knee joint is the most commonly affected site and only 2.5% of cases occur in foot and ankle joint. We have experienced a patient who has of foot and report an optimal method of surgical treatment. Authors report the result of hemangioma in mid-foot which arise from removal of a pigmented villonodular synovitis that has low out break rate of benign tumor in mid-foot with literature review.

  • Pigmented villonodular synovitis (PVNS) is a rare proliferative disorder that affects synovium, tendon sheath and bursa. Although the condition can present in any joint, knee joint is the most commonly affected site and only 2.5% of cases occur in foot and ankle joint. PVNS occurs in two types: localized and diffuse. Localized type is characterized by focal involvement of the synovium with either nodular or pedunculated masses, Diffuse type affects virtually the entire synovium. Diffuse type has reported more recurrence rate. We have experienced a patient who has diffuse type PVNS of ankle joint and report an optimal method of surgical treatment.

  • Pigmented villonodular synovitis (PVNS) is a benign proliferative joint disease with an uncertain etiology that uncommonly involves the spine. We present a case of PVNS involving the lumbar spine. A 38-year-old male developed back pain and pain in both legs caused by a mass in the L4 region of the right lamina. After gross total tumor removal, the symptoms improved. The pathological finding was synovial hyperplasia with accumulation of hemosiderin-laden macrophages. He was diagnosed with PVNS and experienced no recurrence for up to 2 years after surgery. In this report, we review the previous literature and discuss etiology, clinical manifestations, diagnosis, and treatment.

  • Purpose: To purpose of this study was to review the long-term follow up results of surgical treatment of the localized pigmented villonodular synovitis in the knee. Materials and Methods: We evaluated and analyzed 6 patients (6 cases) who underwent arthroscopy and excisional biopsy as pigmented villonodular synovitis from March 1988 to June 2002. The clinical diagnosis was confirmed by pathologic findings. All patients had been managed with arthroscopic excision, but two patients underwent mini-open excision. The recurrence was evaluated by the loss of preoperative symptom and physical examination for range of motion, pain and finding of swelling. Results: According to the arthroscopic findings, all patients had localized form of pigmented villonodular synovitis. Three patients had pedunculated type (one of them had torsion) and the two patients had nodular type and one patient had mixed type. All patients had improvement in pain, swelling and range of motion and there was no evidence of recurrence. Conclusion: In terms of long term follow up results, precise preoperative diagnosis and the adequate surgical treatment, especially arthroscopic excision for the localized pigmented villonodular synovitis, would be considered one of the fundamental modality to expect the good results.
