          Abstract

          Pigmented villonodular synovitis is a benign but locally aggressive extra-articular tumor arising from the synovial membrane of tendons and bursae occurring near a joint space. Rarely, pigmented villonodular synovitis can involve the temporomandibular joint, which is emphasized in this paper. Diffuse and localized types have been described in the literature. The diffuse type involves the entire synovial membrane and infiltrates adjacent structures, which tend to be more aggressive and associated with a higher rate of recurrence when compared with the localized type.

          Giant cell tumor of tendon sheath: case series and review of literature.

          S. Suresh, Hosam Zaki (2010)
          Recurrence of Giant cell tumor of the tendon sheath (GCTTS) is an unresolved issue, though it is a non malignant condition. The authors operated on fourteen cases of GCTTS, after fine needle aspiration cytology confirmation and using a magnifying loupe for complete excision of the lesion including the satellite nodules. In only one case recurrence was noted which was successfully managed by a second wide excision. Preoperative diagnosis and meticulous surgical technique were found the only predictive factor of recurrence. During the 5 year period from 2002, 12 patients [11 females, 1 male, mean age 29.5, ranging from 10-53 years] underwent excision of giant cell tumor of tendon sheath of the hand. The lesions were found over the thumb [n = 7], ring finger [n = 1], index finger [n = 1], and over the hand [n = 2]. The lesions were classified using the Al-Qattan classification. The most common presentation was with a mass over the hand, with a predilection to the thumb [n = 7]. Radiological changes in the form of bony indentation was seen in only 2 cases. FNAC was inconclusive in 2 out of the 12 cases. Due to the high incidence of recurrence, pre-operative planning aided by a tissue diagnosis with fine needle aspiration cytology, wide surgical exposure, and meticulous dissection with help of magnification are imperative for a successful outcome in GCTTS.

            Giant cell tumor of the tendon sheath: Magnetic resonance imaging findings in 38 patients.

            Chao. Wang, Rui-Rui Song, Ping-Ding Kuang … (2017)
            The present study aimed to investigate the value of magnetic resonance imaging (MRI) in the diagnosis of giant cell tumor of the tendon sheath (GCTTS), including localized (L-) and diffuse (D-) types. A total of 38 patients with GCTTS, including 31 with L-GCTTS and 7 with D-GCTTS, diagnosed by surgery and pathology, were retrospectively analyzed. All patients underwent MRI examination. Of the 31 patients with L-GCTTS, the tumors were located in the hand and wrist (18 patients), the ankle and foot (10 cases), the knee joint (2 cases) and the temporomandibular joint (1 case). All 31 lesions were either located in relation to a tendon or were partially/completely enveloping it and all were well marginated. With respect to the 7 D-GCTTS patients, the tumors were located in the ankle and foot (6 cases) or the hand and wrist (1 cases). All 7 lesions presented as an aggressive soft tissue mass infiltrating the tendon sheath and adipose tissue around the joint. The characteristic internal signal of GCTTS, including L-GCTTS and D-GCTTS, was demonstrated by MRI examination. MRI is currently the optimal modality for preoperative assessment of tumor size, extent and invasion of adjacent joint and tenosynovial space.

              Imaging of pigmented villonodular synovitis.

              Sulabha Masih, Alon Antebi (2003)
              Pigmented villonodular synovitis (PVNS) is a rare, benign, idiopathic proliferative disorder of the synovium that results in villous and/or nodular formation in joints, tendon sheaths, and bursae. The disease can be localized or diffuse. Patients with this condition typically present with symptoms of mild discomfort and associated stiffness of the involved joint; however, the spectrum of presentations is broad. Diagnosis of PVNS can be clinically difficult, and plain radiographs are usually nonspecific. Magnetic resonance (MR) imaging is a highly diagnostic modality in characterizing PVNS when it contains hemosiderin deposits exhibiting low signal intensity on all MR image pulse sequences. This article discusses the presentation, pathology, differential diagnosis, diagnostic modalities as well as various treatment options of PVNS.
