Background. Pigmented villonodular synovitis (PVNS) is a rare benign tumor affecting large joints and prompts excision to prevent local destruction of the joint. The purpose of this case report is to describe two differing surgical approaches for management of PVNS of the hip in patients requiring concomitant treatment for additional hip pathology. Methods. This report discusses the presentation, clinical and radiographic findings, and operative management of two contrasting cases of PVNS of the hip. Case 1 describes a 31-year-old female with localized PVNS in addition to a labral tear treated with arthroscopic labral repair followed by tumor excision via a mini-open incision...

BACKGROUND: Tenosynovial giant cell tumor (TSGCT), also known as giant cell tumor of tendon sheath or pigmented villonodular synovitis, is the most common benign tumor of the tendon and synovium. The intra-articular diffuse type can present as a large infiltrative mass involving adjacent soft tissue and sometimes causes secondary destruction of bone, which leads to radiographic and clinical concern for malignancy. The tumor may also be purely extra-articular. CASE: Here, we report the fine needle aspiration cytology findings of 2 cases of diffuse-type TSGCT with large mononuclear cells with eccentric nuclei, finely granular cytoplasm, and a peripheral well-defined cytoplasmic rim of hemosiderin ("ladybird cells")...

Pigmented villonodular synovitis is a benign proliferative tumor of the synovium. It is very rare, and most cases occur in the knee joint. In this article, we report a case of localized pigmented villonodular synovitis in the knee joint of a 14-year-old boy. This condition is rare in the knees of the children. We preferred to remove the tumor with arthrotomy instead of arthroscopy for two reasons: (i) the patient was obese, (ii) we thought that recurrence risk was high after arthrotomy.

Tenosynovial giant cell tumor (TSGCT) is a rare benign tumor arising from joint synovia, bursae and tendon sheaths. Their variable clinical presentation is related to variations in site and progression. Localized forms are most frequent in the hands, and diffuse forms in the knee. MRI is necessary and sometimes sufficient for diagnosis. Treatment strategy is guided by progression, symptomatology, location and diathesis. Optimally complete resection is the principle of first-line treatment. Radiation therapy is effective and targeted therapies are promising; both should especially be considered in case of relapse...

Pigmented villonodular synovitis (PVNS) is a proliferative disorder of unknown etiology that originates from the synovial membranes of joints. Some PVNS lesions have been misdiagnosed as malignancy due to their tumorlike imaging findings. There are few reports of PVNS on nuclear 3-phase bone imaging. However, 3-phase Tc-MDP bone scan can offer additional information about the dynamic flow features of the lesion, which may do help in differential benign and malignant. The present report describes 3-phase bone imaging in a surgically proven case of PVNS with tumorlike appearance and atypical location...

A 23-year-old Japanese woman with no history of corticosteroid intake or alcohol abuse presented with a 10-month history of left hip pain without any antecedent trauma. An anteroposterior radiograph performed 10 months after the onset of pain showed slight joint space narrowing and bone erosions surrounded by sclerotic lesions in both the acetabular roof and femoral neck. Magnetic resonance images of the left hip showed a feature of osteonecrosis of the femoral head and a mass with villus proliferation extending from the posterior intertrochanteric area to the anteromedial aspect of the femoral neck...

This is the case report of a 65-year-old man who experienced left calf pain after spraining his left ankle. On magnetic resonance imaging (MRI), a well-defined fluid collection was identified, with low intensity on T1-weighted images and very high intensity on T2-weighted images. On certain slices, a soft tissue mass in the proximal fibula was identified. Following resection of the fibular lesion, histological examination confirmed a benign tumor with cystic elements, described in the current pathology and radiology literature as juxta-articular myxoma...

Noonan syndrome is a genetic disorder with variable expression of distinctive facial features, webbed neck, chest deformity, short stature, cryptorchidism and congenital heart disease. The association of Noonan syndrome and giant cell granulomas of the mandible is widely reported. However, Noonan syndrome may also be associated with single or multifocal tenosynovial giant cell tumors, also referred to as pigmented villonodular synovitis. We report a child with Noonan syndrome, giant cell granulomas of the mandible and synovial and tenosynovial giant cell tumors involving multiple joints and tendon sheaths who was initially misdiagnosed with juvenile idiopathic arthritis...

PURPOSE: The purpose of this study was to present the long-term results of treatment of localized pigmented villonodular synovitis (LPVNS) comparing two operative procedures of excision of the lesion-the arthroscopic and the arthroscopically assisted mini-open. We hypothesized that the latter approach allowed for treatment of LPVNS with acceptable recurrence rates, complication rates and functional outcomes. METHODS: Between 1990 and 2006, 21 patients with LPVNS were treated with partial synovectomy through an arthroscopically-assisted mini open technique (group A), and 23 patients were treated with an arthroscopic excision of the lesion (group B)...

Pigmented villonodular synovitis (PVNS) is a rare, benign, but potentially locally aggressive and recurrent condition characterized by synovial proliferation and hemosiderin deposition inside the joints, tendon sheaths, and bursae. It usually affects the large joints such as hip, knee, and ankle. We report a case of PVNS of the knee joint in a young female which was treated by subtotal synovectomy alone without the use of adjuvants. At the 14-month follow-up, the patient was pain free and had no signs of disease recurrence...

Sarcoidosis is a systemic inflammatory disorder characterized by non-caseating granulomas, predominantly involving lung, mediastinal lymph nodes and other organs. Synovium involvement is infrequent, and as far as we know, involvement of a periprosthetic membrane has not been reported in the English literature. Intra-articular diffuse tenosynovial giant cell tumor ("conventional diffuse pigmented villonodular synovitis") is an uncommon, locally aggressive neoplasm with few previous case reports in which it arose in periprosthetic tissues after knee arthroplasty...

Pigmented villonodular synovitis (PVNS) is a benign, proliferative disorder of synovium. It often affects the knee, and rarely occurs in the temporomandibular joint (TMJ). This paper reported a 45-year-old male patient with PVNS of the TMJ, who was referred with a chief complaint of slowly growing and painless preauricular mass that was noticed about 1 year. Radical excision and follow-up were conducted, no recurrence and metastasis were noted.

INTRODUCTION: Pigmented villonodular synovitis (PVNS) is a rare, benign proliferative disorder of the synovial membrane that typically presents in adults and affects a single joint. Multifocal PVNS is very rare, particularly in childhood. We reported a rare case of multifocal PVNS affecting over 20 joints in a child. CLINICAL PROCEDURE: A 7-year-old female patient had a 6-month history of multifocal joints swelling with mild pain. She was diagnosed as polyarticular juvenile idiopathic arthritis at a local hospital...

This case concerns a male patient complaining of pain and discomfort in his right elbow, associated with decreased range of motion. Elbow radiography showed an osteolytic lesion in the metaphyseal region of the distal humerus and magnetic resonance imaging showed intra-articular tumor formation with swelling that suggested pigmented villonodular synovitis. Arthroscopic treatment was performed in order to obtain a synovial biopsy and then to carry out total synovectomy. Anatomopathological examination confirmed the diagnosis...
