“…Among the four reports of FTS in young children, one presented a case of FTS that occurred in the patella tendon of a 6-year-old boy [8], and the others described a case series with no details related to the site of occurrence, symptoms, and examination findings [4,5,7]. Here, we report an extremely rare case of FTS that Fig.…”

“…FTS is more common in males than females, with a ratio of 3:1, and mostly occurs in patients aged from 20 to 40 years [4]. There have been few reports of FTS in young children aged under 9 years [4,5,7,8]. Because of its atypical physical and imaging findings, FTS might be misdiagnosed as a soft tissue tumor such as a ganglion cyst or TSGCT.…”

“…Regarding younger cases, Nason et al reported that FTS should not be excised with the surrounding functional tissues because it is a benign tumor and the risk of malignant degeneration is extremely low [23]. In 7 cases of FTS under the age of 20 years, only 2 had symptoms other than swelling [6,8,13,[23][24][25][26]. In the current study, the patient was very young (3 years old) and surgical resection was performed because of the limited range of motion of the finger.…”

Background Fibroma of tendon sheath (FTS) is a rare benign soft tissue tumor that often occurs in the upper extremities. It manifests as a slow-growing mass, often without tenderness or spontaneous pain. FTS occurs most commonly in people aged 20–40 years and is extremely rare in young children. Because FTS presents with atypical physical and imaging findings, it might be misdiagnosed as another soft tissue tumor such as a ganglion cyst or tenosynovial giant cell tumor (TSGCT). Although marginal resection is usually performed, a high rate of local recurrence is reported. Case presentation A boy aged 3 years and 1 month visited our outpatient clinic with a complaint of a mass of the left hand. An elastic hard mass approximately 20 mm in diameter could be palpated on the volar side of his left little finger. This mass was initially diagnosed as a ganglion cyst at another hospital. Ultrasonography revealed a well-circumscribed hypoechoic mass with internal heterogeneity on the flexor tendon. On magnetic resonance imaging (MRI), the mass showed iso signal intensity to muscle on T1-weighted images, and homogeneously low signal intensity to muscle on T2-weighted images. The mass was peripherally enhanced after contrast administration. FTS was initially suspected as the diagnosis on the basis of these imaging features. Because of the limited range of motion of his little finger, surgery was performed when he was 4 years old. Histopathological findings indicated the mass was well-circumscribed and contained scattered spindle cells embedded in a prominent collagenous matrix. The spindle cells contained elongated and cytologically bland nuclei with a fine chromatin pattern. Nuclear pleomorphism and multinucleated giant cells were not observed. On the basis of these findings, we made a diagnosis of FTS. One year after surgery, no signs of local recurrence were observed. Conclusions We experienced an extremely rare case of FTS in the hand of a 3-year-old child. We especially recommend ultrasonography for hand tumors of young children to diagnose or eliminate ganglion cysts. MRI helped differentially diagnose FTS from TSGCT. Although marginal resection can be performed as a treatment, great care should be taken postoperatively because FTS has a high possibility of local recurrence.

“…FTS commonly presents in tendons of the finger, hand and wrist but is much less common in large joints like the knee or shoulder 1 2. To our knowledge, there are 51 reported cases of FTS occurring around large joints 1–31. Incidence of FTS around large joints follows a male to female ratio of 2 to 1 with a reported mean age of 40.9 in a literature review by Suzuki et al 1.…”

“…Incidence of FTS around large joints follows a male to female ratio of 2 to 1 with a reported mean age of 40.9 in a literature review by Suzuki et al 1. Of the 51 reported cases, 40 cases (78.4%) involved the knee, 5 cases (11.1%) the elbow, 4 cases (7.8%) the ankle and 2 cases (3.9%) the shoulder 1–31. Of the 51 reported cases, 32 cases disclosed the precise location of the FTS and 28 referred to the knee joint as the only area of involvement.…”

Arthroscopic treatment for intra-articular fibroma of the tendon sheath in a teenager

et al. 2022

An adolescent female patient presented with atraumatic left knee pain and limited flexion. MRI demonstrated evidence of a soft tissue lesion abutting the posterior cruciate ligament. Differential diagnosis included pigmented villonodular synovitis (PVNS) and fibroma of the tendon sheath (FTS). Following arthroscopic biopsy, histopathological evaluation confirmed FTS. The tumour was then excised via an arthroscopic approach. This case report provides a unique example of FTS abutting the cruciate ligaments in an uncommonly young female patient. It highlights the importance of including benign processes, such as FTS, in the differential with more aggressive-type diagnoses like PVNS. Furthermore, this case exemplifies an appropriate surgical indication for FTS. Finally, it emphasises the importance of communication and collaboration among orthopaedic subspecialists in providing safe and effective arthroscopic treatment of this unique tumour presentation.

ResumenSe presenta un caso de fibroma de la vaina tendinosa, tumor benigno poco frecuente de adultos de 20–40 años y de extraordinaria rareza en la edad infantil, localizado en la cara palmar de la falange media del tercer dedo de la mano derecha de una niña de 6 años. El diagnóstico se efectuó tras su exéresis mediante el estudio histológico de la lesión, pues los estudios de imagen previos mediante ecografía y resonancia magnética no fueron concluyentes. A pesar de que la resección quirúrgica constituye el tratamiento de elección, existe un alto riesgo de recidiva de la enfermedad.
