This case report is concerned with a 30 year old patient diagnosed with pigmented villonodular synovitis (PVNS) in the knee. The patient underwent an orthopedic surgical operation to remove the lesions. PVNS is a rare proliferative disorder, mostly benign and affecting the knee; its aetiology remains unclear. It represents a medical challenge because of non-specific symptoms that delay the diag...
Pigmented villonodular synovitis (PVNS) is an uncommon benign proliferative disorder of synovium that may involve joints, tendon sheaths, and bursae. It most often affects the knees, and less frequently involves other joints. It presents in the temporomandibular joints (TMJs) extremely rarely. The authors report an elderly female patient with PVNS of the TMJ with skull base extension, who had t...
Pigmented villonodular synovitis (PVNS) is benign proliferative disorder of the synovium of unknown origin. PVNS is divided into intra-articular and extra-articular form which may present as i) diffuse or ii) localised/nodular form. It is commonly seen in knee joint but hip, ankle, shoulder, wrist & other joints can be involved. It is usually seen in young adults from 20-50 years of age. It is ...
two rare cases of extra-articular diffuse variant giant cell tumor of the tendon sheath are presented, at the elbow of a 68-year-old female and the foot of a 56-year-old male. both patients presented with a palpable masses and marginal excision was performed; histological sections confirmed the diagnosis of extra-articular giant cell tumor. no adjuvant therapy was administered. at the last foll...
INTRODUCTION Malignant pigmented villonodular synovitis (PVNS) or Malignant giant cell tumour tendon sheath (MGCTTS) is a controversial and debatable lesion. Few case reports have indicated the potential for metastasis.1These aggressive cases are designated malignant giant cell tumour tendon sheath or malignant PVNS. Less than 20 cases are described in literature. We report a case of 65 year ol...
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 synovect...
There are only a few reported cases in the literature of pigmented villonodular synovitis (PVNS) involving the elbow. Even more rare is its occurrence in the pediatric population as this condition mainly affects young adults. We report a unique case of an 8 year old girl presenting with diffuse form of PVNS of the elbow. The diagnosis is often not considered by clinical history and plain films ...
Tenosynovial giant-cell tumor (TGCT) and pigmented villonodular synovitis (PVNS) are related conditions with features of both reactive inflammatory disorders and clonal neoplastic proliferations. Chromosomal translocations involving chromosome 1p13 have been reported in both TGCT and PVNS. We confirm that translocations involving 1p13 are present in a majority of cases of TGCT and PVNS and show...
