Pigmented Villonodular

Pigmented villonodular synovitis is a rare, benign, but potentially locally aggressive disease that should be considered in younger patients who present with monoarticular joint symptoms and pathology. We present the case of a 33-year-old woman with a mass arising from her right hip joint that was examined using a multimodal radiological approach. Because her clinical presentation mimicked that of synovial osteochondromatosis of the hip, surgical dislocation was performed. Histopathological examination of the resected specimen confirmed the diagnosis of localized pigmented villonodular synovitis, with the mass consisting of proliferation of fibrohistiocytic cells, abundant hemosiderin, foamy histiocytes, and occasional giant cells. Because of the presence of tumor necrosis, we hypothesize that torsion of the tumor pedicle was the cause of acute presentation.

Pigmented Villonodular

Background: PVNS is a rare, benign & aggressive disorder arising from either synovial joints or tendon sheaths; it may erode articular structures and bones. We present a case with unique features of PVNS being extra-synovial and by this report we open a gate for more researches in this field. Case Presentation: This case report concerns a 35-year-old female with a history of right knee pain for 6-month duration proceeded by gradual swelling over posterior aspect of the knee, she denies any history of trauma, clinical examination was unremarkable but apart from tenderness over the infrapatellar region with full flexion. MRI shows a heterogenous signal extra-articular and extra-synovial lesion in posterior aspect of the knee suggesting Pigmented Villonodular Synovitis, FNA revealed a hemosiderin-laden macrophages and multinucleated giant cells, Tru-cut biopsy result was suggesting PVNS as synovial cells were seen admixed with hemosiderin-laden macrophages with fibroblastic elements. Through posterior approach; the lesion was surgically excised and histopathological examination confirmed the diagnosis, the lesion was recurrent after 1-year and MRI revealed the same features, the lesion was excised by arthroscopic intervention. Conclusion: We concluded that PVNS cannot be excluded when extra-synovial lesion is assessed, and further researches on this topic will expand our understanding of the etiological and pathological aspects of this tumor.

Pigmented Villonodular

A 39-year-old woman had a large asymptomatic left parotid mass that she had apparently not noticed. The clinical appearance suggested a parotid tumor. Aspirated tissue revealed numerous giant cells, histiocytes, and hemosiderin pigment. At surgical exploration a tumor was found deep to the facial nerve involving the temporomandibular joint, which had a brown-stained roughened synovial membrane. The resected specimen histologically was a proliferative lesion composed of epithelioid histiocytes, spindle cells, and multinucleated giant cells. The appearance was typical of the family of lesions that includes pigmented villonodular synovitis, bursitis, and tenosynovitis (giant cell “tumor” of tendon sheath). In view of the origin from the temporomandibular joint, reinforced by a characteristic radiologic appearance, we interpret this as a case of pigmented villonodular synovitis. This is the fifth case reported from this site.

Introduction: Chronic synovitis involving a single large joint remains a diagnostic dilemma. We present 61 cases of chronic synovitis of the knee, followed prospectively for 2 years. The study focuses on the diagnosis, management, and histopathological correlation. Methods: We prospectively studied 61 patients with chronic mono-articular synovitis of the knee joint, between July 2016 and September 2017. All patients underwent plain radiographs, magnetic resonance imaging, and arthroscopic examination with synovial biopsy. Further treatment was based on findings of histopathological examination. Results: The average duration of symptoms was 7.72 ± 4.34 months. The mean age at presentation was 29.93 ± 15.56 years. Results of histopathological examination showed chronic nonspecific inflammation in 28 patients (46%), features suggesting tubercular infection in 19 patients (31%), pigmented villonodular synovitis in seven patients (11.5%), rheumatoid arthritis in three (5%) patients, acute inflammation in three (5%) patients and findings suggestive of synovial chondromatosis in one (1.5%) patient. Treatment was based on histopathological results. Intra-articular injections of methylprednisolone (80 mg depot preparation) were given to all patients with nonspecific synovitis and rheumatoid arthritis. Anti-tubercular treatment was started for patients with tubercular synovitis. Complete arthroscopic/open synovectomy followed by radiotherapy was carried out for patients with pigmented villonodular synovitis. Non-steroidal anti-inflammatory drugs are used for patients with acute on chronic inflammation. All patients had symptomatic relief and functional improvement in further follow-up. Discussion: Histopathological reporting remains the mainstay for diagnosis. The various differentials should always be kept in mind when approaching patients with chronic mono-articular synovitis. Specific treatment can be started once the diagnosis is confirmed.
