Objective: This study was conducted to analyse the clinicopathological and radiological features associated with Synovial lipomatosis.Patients and Methods: Cases diagnosed as Synovial lipomatosis from 2008 to 2018 were retrieved and clinical information and histology were reviewed.Results: Thirteen cases of Synovial lipomatosis were diagnosed between 2008 and 2018. Most common site was knee joint and mean age of presentation was 28.6. About 62% of subjects were males and mostly presented with joint pain and swelling. Two of the subjects had significant history of trauma and disease was bilateral in one of the cases. Microscopically, villous proliferation of synovium with infiltration of mature adipocytes was noted. Focal synovial hyperplasia and inflammatory infiltrate were other findings in some of the cases.Conclusion: Synovial lipomatosis should be considered in the differential diagnosis of joint pain and swelling and should be distinguished from Pigmented villonodular synovitis, Synovial haemangioma and intra-articular synovial lipoma (IASL) using radiological and histological features.

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.

<p class="abstract">A 28 year old woman had a history of knee trauma and presented with unilateral knee acute swelling and pain symptoms with sudden onset, which was there from last 2 years. She had been treated for seronegative rheumatoid patient for 1 year. Recent expansion of the LPVNS (localized pigmented villonodular synovitis) caused the development of a tender palpable soft tissue mass in the anterolateral aspect of the knee and acute reduced mobility. Preoperative magnetic resonance imaging of the knee revealed the presence of only the soft tissue mass and mild degenerative changes. Open synovectomy was performed successfully to excise the mass. Intraoperatively, macroscopic features of the bright brown inflamed synovium suggested LPVNS, which was confirmed histopathologically. Postoperatively, the symptoms of limited mobility and pain were appreciably relieved. Recurrence was not observed during the clinical follow up at 1, 6 or 18 months after surgery. Here, we reported the unique case of localized pigmented villonodular synovitis of the knee in a misdiagnosed patient with intra and extraarticular lesion, which might be attributed to the history of knee trauma and the focal defect of the lateral patellar retinaculum. Open synovectomy effectively relieved the symptoms of limited mobility and pain and no recurrence was observed prior to 18 months postoperatively. To reduce misdiagnosis, MRI examinations are recommended for all patients suspected of having PVNS, including those who have a history of hyperuricemia.</p>

Abstract Background Pigmented villonodular synovitis (PVNS) is a rare, benign, proliferative neoplastic process that commonly affects synovial-lined anatomic spaces. The diffuse type (DPVNS) is characterized by invasion of the entire joint synovium, while the localized type (LPVNS) is characterized by a relatively normal synovial appearance. This report describes a unique case of massive intraarticular LPVNS with an extraarticular extension through the lateral patellar retinaculum. No similar cases have been found in the literature. Case presentation A 58-year-old woman had a history of hyperuricemia and knee trauma and presented with unilateral knee acute swelling and pain symptoms with sudden onset. Recent expansion of the LPVNS caused the development of a tender palpable soft tissue mass in the anterolateral aspect of the knee and acute reduced mobility. Preoperative magnetic resonance imaging of the knee revealed the presence of only the soft tissue mass and mild degenerative changes. Open synovectomy was performed successfully to excise the mass. Intraoperatively, macroscopic features of the bright brown inflamed synovium suggested LPVNS, which was confirmed histopathologically. Postoperatively, the symptoms of limited mobility and pain were appreciably relieved. Recurrence was not observed during the clinical follow-up at 1, 6 or 18 months after surgery. Conclusions Here, we report the unique case of localized pigmented villonodular synovitis of the knee in a misdiagnosed patient with intra- and extraarticular lesion, which might be attributed to the history of knee trauma and the focal defect of the lateral patellar retinaculum. Open synovectomy effectively relieved the symptoms of limited mobility and pain and no recurrence was observed prior to 18 months postoperatively. To reduce misdiagnosis, MRI examinations are recommended for all patients suspected of having PVNS, including those who have a history of hyperuricemia.
