Pigmented Villonodular Synovitis (PVNS) is an uncommon condition of the foot. PVS of the foot accounts for 2% of all cases. We present the case of a 26 year-old male who was found to have pigmented villonodular synovitis of the second metatarsophalangeal joint. Although a high incidence is reported in the literature, the patient underwent surgical excision with no known reoccurrence to date. Fi...

Pigmented villonodular synovitis in temporomandibular joint is an uncommon disorder. There are only 39 cases reported in the English literature. Here we report a case with this disease. The patient was a 52-year-old female suffering from progressive right pre-auricular pain and limitation in open mouth for 2 years. Physical examination revealed a palpable nodule in the right preauricular area. ...

Pigmented villonodular synovitis (PVNS) is a rare, benign, proliferative disease of the synovial membrane of joints, tendon sheaths, and bursas. It usually presents in two forms, diffuse and localized. A 35-year-old male, since adolescence, presented left knee pain with palpable, multiple nodular tumorous lesions in the infrapatellar fat pad. An arthroscopic excisional biopsy was performed. Mul...

Pigmented villonodular synovitis (PVNS) is a rare disease that can affect any joint, bursa or tendon sheath.The hip is less frequently affected than the knee, and hence is less discussed in scientific journals.PVNS of the hip mainly occurs in young adults, requiring early diagnosis and adequate treatment to obtain good results.There is no consensus on the management of PVNS of the hip in curren...

Pigmented villonodular synovitis (PVNS) is an uncommon lesion nearly always occurring in the large synovial joints of the extremities. Involvement of the vertebral column is rare , having been previously reported only four times. The present report describes the myelographic and postmyelographic CT appearance of PVNS arising from a lumbosacral facet joint and extending within the spinal canal a...

Pigmented villonodular synovitis (PVNS) is a rare benign neoplastic proliferation of synovial tissue which is typically localised and usually responds well to surgery and/or radiotherapy. We present a case of unusually aggressive of PVNS of the hip in a 73-year-old woman.

We describe a surgical treatment for popliteal cyst in a 41-year-old woman affected by diffuse pigmented villonodular synovitis (PVNS) of the knee with extra-articular spreading. The treatment consists of an arthroscopic synoviectomy followed immediately by an open removal of the cyst. At 28-month follow-up, the patient is asymptomatic and no evidence of recurrence of PVNS has been seen. We bel...

Malignant pigmented villonodular synovitis (PVNS) (or malignant giant cell tumor of tendon sheath (GCTTS) is an extremely rare condition defined as a malignant lesion occurring with concomitant or previously documented PVNS at the same site. To date, only less than 20 cases have been reported in English literatures. We report a case of malignant PVNS in the knee in a 56-year-old woman with unpr...

This is an isolated case of a giant cell tumor originating from the synovium of the hip, consistent with Pigmented Villonodular Synovitis (PVNS) and associated with concurrent Femoroacetabular Impingement (FAI). There is a paucity of literature on this condition. This case report will add to the literature on hip pathology that may be treated using arthroscopic surgery.

Pigmented villonodular synovitis (PVNS) is a rare, benign, proliferative neoplastic condition affecting synovial-lined anatomic spaces. PVNS is characterized by hypertrophy of a synovial membrane by villous, nodular, and villonodular proliferation, with pigmentation secondary to hemosiderin deposition. The two forms of PVNS that have been described are diffuse (DPVNS) and localized (LPVNS). The...
