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 proliferative disease that affects the synovial joint, tendon and bursa. PVNS can form a nodular structure in any joint, but it most commonly affects the knee joint and is rare in the foot and ankle joint. PVNS is divided into two types. Localized-type PVNS exhibits focal involvement with a nodular mass, while diffuse-type PVNS involves the entire synovium. Synovitis of the affected joint can also destroy cartilage and bone. Diffuse type accounts for 75% of PVNS and has a reported recurrence rate of 12.2% to 46%; aggressive synovectomy is recommended as the most effective treatment. In localized-type PVNS, only arthroscopic partial synovectomy is effective with a lower recurrence rate. We report a patient with severe ankle joint arthritis induced by diffusetype PVNS. The patient was treated by lateral malleolar ostectomy and ankle arthrodesis with a plate and screws via a lateral approach.

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) in ankle is relatively uncommon. This disorder results in increased proliferation of synovium causing villous or nodular changes containing histiocytes, fibroblasts, multinucleated giant cell, and hemosiderin. PVNS is classified into two different type : localized and diffuse. Diffuse type of PVNS in ankle is more common than localized type. Also, recurrence of diffuse type is more frequent. We report a case of diffuse type of PVNS which was recurred soon after the excision.

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 slowly, progressive, proliferative disorder of synovial tissue characterized by villous or nodular changes of synovial-lined joints, bursae, and tendon sheaths and most frequently affects the large joints, with the knee and hip. A few studies have been reported that occurred PVNS in small joint, but mainly in hands. It is a very rare condition that occurs in the small joints of the forefoot. We have experienced the case, which developed in small joint of the forefoot, and performed total synovectomy. After the operation, there was no recurrence. We report a case of PVNS in forefoot with a review of the literature.

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.

Nodular fasciitis (NF) is a benign myofibroblastic proliferation that grows very rapidly, mimicking a sarcoma on imaging. It is treated by local excision, and recurrence has been reported in only a few cases, even when excised incompletely. The most prevalent diagnoses of temporomandibular joint(TMJ) masses include synovial chondromatosis, pigmented villonodular synovitis, and sarcomas. Cases of NF in the TMJ are extremely rare, and only 3 cases have been reported to date. Due to its destructive features and rarity, NF has often been misdiagnosed as a more aggressive lesion, which could expose patients to unnecessary and invasive treatment approaches beyond repair. This report presents a case of NF in the TMJ, focusing on various imaging features, along with a literature review aiming to determine the hallmark features of NF in the TMJ and highlight the diagnostic challenges.
