“…It is observed that for localised GCTTS, the tumour does not move with the tendon during flexion and extension, as it arises from the tendon sheath and not the tendon itself [38,43]. Underlying bony erosions may also be visualised in about 16% of cases [43,46]. US can also provide information about the extent of contact and circumferential involvement of the tendon that can be helpful for surgical planning.…”

Giant cell tumours of the tendon sheath (GCTTS) and pigmented villonodular synovitis (PVNS) are part of a spectrum of benign proliferative lesions of synovial origin that may affect the joints, bursae and tendon sheaths. This review article describes the clinicopathological features and imaging findings in patients with GCTTS. GCTTS usually presents as a soft tissue mass with pressure erosion of the underlying bone. Magnetic resonance (MR) imaging of GCTTS typically shows low to intermediate signal on T1- and T2-weighted spin-echo sequences due to the presence of haemosiderin, which exerts a paramagnetic effect. On gradient-echo sequences, the paramagnetic effect of haemosiderin is further exaggerated, resulting in areas of very low signal due to the blooming artefact. Ultrasonography shows a soft mass related to the tendon sheath that is hypervascular on colour or power Doppler imaging.

A giant cell tumour of the tendon sheath (GCTTS) originates from the synovial cells of the tendon sheath. It has a slow clinical course and is one of the most common soft tissue tumours of the hand. Although less common, it may also be observed in the ankle, elbow, knee, wrist, spine, and fingers. The pathological nature of this disease is controversial. Some authors consider that it has a neoplastic nature, whereas other believe it is a non-neoplastic tumour. The underlying etiology is believed to include trauma, inflammation, metabolic diseases, and neoplasia. The most widely accepted pathogenic hypothesis is reactive or regenerative hyperplasia associated with an inflammatory process. The treatment of GCTTS is surgical excision. There is a high rate of recurrence of the tumour after excision. Many factors are considered as causing recurrence, including incomplete excision of the lesion, proximity to the distal interphalangeal joints, presence of degenerative joint disease, radiological erosion and increased mitotic activity. To prevent recurrence is complete surgical excision with removal of all satellite nodules if present [1][2][3]. We aimed to investigate the relation between GCTTS recurrence and the Ki-67 proliferation index. At the same time, we reviewed the literature and performed a retrospective analysis of clinicopathological findings of GCTTS. METHODSIn this retrospective study, we evaluated 35 patients diagnosed with GCTTS in the

“…It is the second most common benign soft tissue tumor of the hand after the ganglion cyst [2]. The tumor affects digits more often than large joints (53.33%) [3]. It can also be seen in other parts of the body including the ankle, wrist, elbow, toes, knees, hips, and spine [4].…”

“…Magnetic Resonance (MR) imaging is useful for the diagnosis because it demonstrates the characteristic features of the tumor. These include low signal intensity equal to or slightly higher than the signal intensity of skeletal muscle on T1 and T2 weighted images (WI) [3,5]. In this study, we evaluated 25 cases of histologically proven GCTTS in the finger with MR imaging findings and also reviewed its epidemiological features.…”

We also evaluated the literature regarding GCTTS and performed an analysis of the available information. Material and Method: We retrospectively reviewed the MR images of 25 histologically proven cases of GCTTS of the finger during the period between 2012-2014. In addition, a retrospective analysis of the patients' records was carried out, and age, gender, site and size of lesion, recurrence, and MRI findings were reviewed. Results: The patients were predominantly female (n = 16) and had a mean age of 51.9 ± 12.8 years. Nine patients were male with a mean age of 45.1 ± 13.4 years. The size of the tumors ranged from 6 mm to 30 mm, with a mean size of 15.3±6.8 mm. Tumors were present on the right hand in 15 patients and on the left hand in 10 patients. Among women, 11 tumors were located on the right hand and 5 were found on the left. In men, 4 of the tumors were located on the right hand and 5 were on the left. The most frequent digit on which tumors were found was the index finger, accounting for 40% of cases (n=10). The most frequent location was the index finger for both women (n=6) and men (n=4). All of the lesions were described as well-circumscribed, encapsulated, lobulated, or multilobulated solitary masses with MR imaging. Signal intensity on T1 weighted images (WI) was equal to that of skeletal muscle in 23 cases. In two cases, signal intensity was slightly higher. On T2WIs, the signal intensities tended to be between those of skeletal muscle and fat in all of the cases. All of the lesions showed mild to moderate contrast enhancement when compared with precontrast images. There was no statistically significant differences between male and female patients in terms of age, tumor side, involved digit, and highest tumor size. But, tumor volume was slightly larger in female patients compared with male patients (p= 0.083). Discussion: MR imaging is very valuable in the diagnosis of GCTTS because of characteristic internal signal intensity. Also, axial and sagittal images are useful for evaluating the degree of extension around the phalanx, and invasion into the joint and tenosynovial space prior to surgery. These factors can influence the surgical approach.
