BackgroundFibroma of tendon sheath (FTS) is a benign tumor arising from the synovium of the tendon sheath that occurs mostly around small joints such as the fingers, hands, and wrist. However, FTS rarely arises around a large joint (knee, shoulder, elbow, and ankle) with intra-articular or extra-articular involvement. The clinical characteristics of FTS arising around a large joint are unclear. An additional 3 cases of FTS arising around a large joint are presented. Furthermore, the published cases and the present cases are reviewed with respect to their clinical characteristics and imaging and histopathology findings.MethodsThe 43 reported cases including the present 3 patients were summarized, and the patients’ profiles, symptoms, sites and locations in the joint involved by FTS, magnetic resonance imaging (MRI) findings, surgical procedures, clinical courses, and cytogenetic analyses were reviewed.ResultsThe average age of 26 cases was 40.9 years (range 13–69 years), and about 60% of the patients were male. About 10% of the patients had a past history of trauma to the knee joint. Of the present 3 cases, one case was extra-articular around the elbow joint, one case was extra-articular around the knee joint, and one case was intra-articular involving the knee joint. The common symptoms were pain (62.5%), swelling or palpable mass (54.2%), and limited range of motion of the involved joint (50%). The most commonly involved joint was the knee, with 32 cases (74.4%), followed by the elbow in 5 cases (11.6%), ankle in 4 (9.3%), and shoulder in 2 (4.7%). The tumor typically exhibited iso to low signal intensity on T1-weighted MRI. T2-weighted images showed various patterns, but mostly low signal intensity relative to muscle. The surgical margin was marginal resection in all cases. There were no recurrences after surgery. On chromosomal analysis, only the present Case 3 showed an abnormality.ConclusionsA total of 43 FTS cases that occurred around large joints were summarized. The most common site was around the knee joint. In FTS cases around large joints, it is necessary to distinguish between various fibroblastic and/or fibrohistiocytic tumors.

“…Fox et al reviewed six cases of FTS to identify the MRI characteristics [2]. According to these authors, the diagnosis of FTS can be suggested when MRI reveals a focal nodular mass adjacent to a tendon sheath with decreased signal on all pulse sequences and little or non-enhancement [2]. Other reports suggest that the signal characteristics could vary from intermediate to low or isointense to muscle with heterogeneity [3][4][5].…”

“…FTS rarely occurs in the synovial membrane of the joint capsule; in such cases, symptom of onset is rather joint discomfort or swelling. Intra-articular FTS of the knee is rare, considering that only eight previous cases have been reported in the English literature [1][2][3][4][5][6][7]: two in the infrapatellar fat pad, one in the posterior cruciate ligament (PCL), one in the suprapatellar pouch, one in the posterior joint capsule, and one located between the posterior capsule and the PCL. We describe the ninth case of FTS located in the intercondylar space dorsal to the PCL of a teenager's knee.…”

Fibroma of tendon sheath (FTS) is a rare dense fibrous benign tumor that majorities are found over the tendons or tendon sheaths of limbs, with predilection in order starting with fingers, hands, wrists, and other parts.1 Almost 80% of tendon sheath fibromas are found over hands and wrists. 2 The typical morphological feature is a solid nodule that is painless and slow growing in nature. Fibromas of tendon sheath rarely arise from knee joints. To our best knowledge, less than 20 such cases have been reported, and none of them was a Chinese patient. We present a case of intra-articular fibroma of tendon sheath of the knee that was excised arthroscopically. Case ReportA 36-year-old male patient had complained a painless mass over the suprapatellar region of left knee for 2 months. He did not complain any systemic upset, and he did not recall any trauma history. Physical examination showed a palpable mass over a suprapatellar region of left knee, which was mobile and firm. The range of motion of the left knee was from 0 to 110 degrees. The joint line was not tender. All special tests including McMurray test, Lachman test, and grinding test of patella were negative. X-ray examination of the knee showed no bony abnormality. Preoperative magnetic resonance imaging (MRI) of the left knee showed a suprapatellar mass measured 3 cm Â 2 cm, hypointense in T1-weighted image (►Fig. 1) but hyperintense in T2-weighted image (►Fig. 2).Arthroscopic examination of left knee was performed under spinal anesthesia. The tumor was located at the suprapatellar region as shown in MRI. The isolated circumferential mass was grayish, and there was a stalk attaching to the superior pole of the patella (►Fig. 3). The tumor was excised through anterolateral and anteromedial portals (►Fig. 4). Pathology showed that the mass was covered by synovium on one side with the solid grayish white cut surface (►Fig. 5). Histology confirmed a bland-looking spindle-celled neoplasm with infarctive necrosis at the subsynovial region (►Fig. 6). The tumor had low cellularity, Keywords► intra-articular fibroma ► fibroma of tendon sheath ► knee joint ► arthroscopy AbstractIntra-articular fibroma of tendon sheath is a rare disease. To our knowledge, less than 20 cases have been reported in the literature, and none of them was a Chinese patient. In this case report, we present a Chinese patient with intra-articular fibroma of tendon sheath of the knee joint which was excised arthroscopically. We also summarized the clinical presentation, diagnosis, and subsequent management of intra-articular fibroma of tendon sheath.
