Pigmented villonodular synovitis (PVNS) is a benign proliferative condition which affects the synovial tissue and is a subtype of tenosynovial giant-cell tumor . This rare condition is believed to be an inflammatory process and can either be localized (L-PVNS) or diffuse (D-PVNS), the latter accounting for the majority of cases [ 2 ] The pathoaetiology of PVNS has been linked to inflammatory, vascular and traumatic causes but chromosomal abnormalities, autonomous growth, bone invasion and the rare malignant transformation of PVNS suggest a neoplastic cause (https://online.boneandjoint.org.uk/doi/epub/10.1302/0301-620X.95B3.30192) Introduction. Pigmented villonodular synovitis was first described by Chassaignac (, 1) in 1852 as a nodular lesion of the synovial membrane that affects the flexor tendons of the fingers.However, the current description of this entity was not applied until 1941 by Jaffe and colleagues (, 2), who used the designations pigmented villonodular synovitis (PVNS), pigmented villonodular bursitis. Intra-articular post-traumatic ankle joint mass is a rare entity that may mimic other pathologies, mainly localized form of pigmented villonodular synovitis (LPVS) regarding the clinical and imaging characteristics
The histopathological diagnosis was post-traumatic HS with no evidence of PVNS or malignancy. The patient showed significant clinical and radiological improvement postoperatively with no evidence of recurrence. CONCLUSIONS Post-traumatic HS is a very rare entity that should always be considered in the differential diagnosis of synovitis in. Pigmented Villonodular Synovitis (PVNS) of Knee Pigmented Villonodular Synovitis or PVNS is a more serious form of synovitis, which results in enlargement of synovial membrane leading to formation of a benign tumor. The hip and knee joints are more commonly affected by Pigmented Villonodular Synovitis or PVNS Materials and methods: This was a retrospective review of MRI findings of 22 paediatric intra-articular congenital or neoplastic synovial lesions, including venous malformation (VM) (n=12), pigmented villonodular synovitis (PVNS; n=8), and synovial sarcoma (SS; n=2). These MRI features were compared with 22 paediatric post-traumatic or. The histopathological diagnosis was post-traumatic HS with no evidence of PVNS or malignancy.

Intra-articular post-traumatic ankle joint mass is a rare entity that may mimic other pathologies, mainly localized form of pigmented villonodular synovitis (LPVS) regarding the clinical and. Although magnetic resonance (MR) imaging has been used to evaluate many musculoskeletal lesions, the MR appearance of pigmented villonodular synovitis (PVNS) has not been described in detail. The authors describe two cases of PVNS in the knee imaged with both computed tomography and MR. Post-traumatic synovitis presenting as a mass in the. Pigmented villonodular synovitis (PVNS) is a rare proliferative process that affects the synovial joint, tendon sheaths, and bursa membranes [ 1 ]. The estimated incidence of PVNS is around 1.8 cases per million people in a population [ 1 ]. PVNS is usually found in adults aged 20-50 years, but it may also be found in children [ 2, 3, 4 ] Monoarthritidies have a relatively short differential diagnosis, including: Common septic arthritis osteoarthritis (post-traumatic) gout Charcot joint (neuropathic joint) pigmented villonodular synovitis (PVNS) synovial osteochondromatosi.. In a total/radical synovectomy, for a diffuse process (like diffuse PVNS or an infected arthroplasty revision), most/all of the visualized synovium is excised. In a limited or partial synovectomy, for localized pathologies (like localized knee PVNS or post-traumatic elbow contractures), only the pathological regions of the synovium is excised
Reddish-brown synovial fluid was aspirated from seven patients which can be seen in post-traumatic hemarthrosis, pigmented vilo-nodular synovitis (PVNS) or hemophilic arthritis. Synovial fluid culture or Ziehl-Neelsen staining was not positive in any of the cases . Definition: benign proliferative disease of the synovium affecting joints, bursae, and tendon sheaths (called giant cell tumour of tendons sheath) Clinical: pain/ restricted movements. Types: diffuse-common (Shag carpet type or fern like proliferation of synovium) , and rarer focal.
Intraoperatively, there was a large effusion containing yellow clots. The histopathological diagnosis was post-traumatic HS with no evidence of PVNS or malignancy. The patient showed significant. Abstract Lumbar pigmented villonodular synovitis is rarely localized on the lumbar spine. Awareness of pigmented villonodular synovitis is important despite its rarity because it may mimic several.

A discussion of the synovial and bursal equivalents of the tenosynovial lesion commonly denoted as xanthoma, xanthogranuloma, giant cell tumor or myeloplaxoma of the tendon sheath, with some consideration of this tendon sheath lesion itself
When compared to pigmented villonodular synovitis (PVNS), synovial lipomatosis can be differentiated by lack of hemorrhage and hemosiderin on histology. Hoffa disease is limited to the infrapatellar fat pad and is typically post traumatic. Thorough knowledge of the differential is imperative in attaining the correct diagnosis Hoffa's (infrapatellar) fat pad (HFP) is one of the knee fat pads interposed between the joint capsule and the synovium. Located posterior to patellar tendon and anterior to the capsule, the HFP is richly innervated and, therefore, one of the sources of anterior knee pain. Repetitive local microtraumas, impingement, and surgery causing local bleeding and inflammation are the most frequent.
Intrinsic pathologies include Hoffa disease, intracapsular chondroma, localized nodular synovitis, or postsurgery or post-traumatic fibrosis. Extrinsic pathologies include articular disorders (e.g., meniscal cyst), synovial abnormalities (e.g., pigmented villonodular synovitis [PVNS]), and anterior extracapsular abnormalities A ganglion cyst is fluid filled sack that appears a lump or bump under the skin. In the foot this most often occurs on the top of the foot or at the big toe joint. The fluid within a ganglion cyst is actually synovial fluid (the fluid that lubricates your joints). The ganglion itself is a little balloon of synovial tissue that has squeezed out. Pigmented villonodular synovitis (PVNS) is a less common but known cause of joint pain in the adult population. PVNS in pediatric patients is even more rare, with only case reports of occurrence in persons under the age of 18 years. Presentation is typically that of more insidious pain and limited range of motion, and is primarily seen in the knee joint Cellulitis occurs when bacteria enters the body through a cut or wound in your skin. This bacteria is not usually harmful when it comes in contact with skin that isn't broken — it's only when it enters through a crack or break in the skin that it becomes dangerous and can lead to an infection like cellulitis. Cellulitis most often occurs.
