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.

색소 융모 결절성 활막염은 양성 증식성 활막의 병변으로 관절이나 건초, 점액낭 등을 침범한다. 이는 주로 한 관절에 발생하며, 다 관절 침범은 1% 미만에서 보고되고 있다. 또 슬관절 및 수부에 주로 발생하며, 견관절에서 발생하는 경우는 드물다. 색소 융모 결절성 활막염의 치료에 대해서는 아직까지 논란이 많은 상태이나 일반적으로 활액막 전 절제술이 표준치료로 알려져 있다. 저자들은 양측 견관절에 동시에 발생한 색소 융모 결절성 활막염으로 내원한 환자에 대해서 관절경적 활액막 절제술을 시행하여 수술소견과 임상 경과에 대해 문헌고찰과 함께 보고하고자 한다.

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.

색소 융모 결절성 활액막염은 슬관절에 호발하고 슬와부로 팽창되는 경우는 드물며 이 경우 베이커씨 낭종이나 악성 종양으로 오진될 수도 있다. 저자들은 슬와부로 팽창되어 낭종을 형성한 미만성 색소 융모 결절성 활액막염을 관절경적 활액막 전 절제술과 낭종 제거술로 치료하였고 1년 이상의 추시 기간상 재발이 안된 1례를 보고하는 바이다.

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.

목적: 슬관절에 발생한 국소형 색소융모결절성 활액막염 환자에 대하여 수술적 치료를 시행한 후 5년 이상 장기 추시하여 임상적 결과를 알아보고자 하였다. 대상 및 방법: 1988년 3월부터 2002년 6월까지 관절경 및 조직병리학적 검사상 국소형 색소융모결절성 활액막염으로 확진된 6예를 대상으로 하였다. 모든 예에서 관절경을 이용하여 병변을 확인한 후 관절경적 방법만으로 절제적 생검술을 시행하도록 노력하였으나, 2예에서는 소절개를 이용하여 적출하였다. 술전 증상의 소실 여부 및 이학적 검사 등을 통하여 재발 여부를 분석하였다. 결과: 모든 예에서 관절경 소견상 국소형이었고 그 중 3예는 자루형, 2예는 결절형, 1예는 혼합형 종물이었다. 3예의 자루형중 1예에서 뚜렷한 염전 소견이 있었고, 종물의 크기가 매우 커서 전내측에 소절개를 가하여 적출한 1예 및 후방구획에 존재하여 후내측에 소절개를 시행하였던 1예를 제외하고는 관절경적 방법만으로 적출하였다. 모든 예에서 술전 증상은 소실되었고 최종 추시시 재발을 의심할만한 소견은 관찰되지 않았다. 결론: 국소형 색소융모결절성 활액막염은 특히 관절경을 이용한 경우 정확한 병소파악을 통한 진단과 완전 절제에 의한 근본적인 치료가 가능하여 장기 추시시에도 좋은 결과를 기대할 수 있을 것으로 생각한다.
