ABSTRACT Background: the giant cell tumor of the tendon sheath occupies the second place in frequency in the neoplasms of the hand. The diagnosis is clinical and radiological, confirmed by anatomic-pathological studies. Objective: to describe the epidemiology, clinical and histological aspects of the giant cell tumor of the tendon sheath. Methods: a descriptive observational study was carried out for the report of six cases from the files of the Department of Pathology from 2016 and 2018, to identify the cases with a diagnosis of giant cell tumor of the tendon sheath. Results: a total of six cases of giant cell tumor of the tendon sheath were diagnosed, corresponding 50% to each sex; the majority were under 40 years old; and in all cases the site of presentation of the tumor was the hand; with a predominance in the palm region of the thumb. None of the cases manifested pain. In the morphological study, the characteristic histological elements of the giant cell tumor of the tendon sheath were observed microscopically. Conclusions: the six patients studied presented the typical symptoms of the Giant cell tumor of the tendon sheath, referring to an increase in volume that was corroborated with the physical examination by palpating a mass of subcutaneous, non-painful, smooth, soft tissue with well-defined borders. In the same way, histopathologically, the characteristic morphological elements were corroborated, for which it can be established that there was a clinical-pathological correlation of 100%.

Tarsal villonodular tenosynovitis (giant cell tumor of tendon sheath) in a dog / Tenossinovite vilonodular pigmentada (tumor de células gigantes da bainha tendínea) tarsal em um cão

ABSTRACT: A 12-year-old female mixed-breed dog presented with lameness, pain, and an enlarged, non-ulcerated, nodular mass in the region proximal to the tarsal joint of the right pelvic limb. Surgical excision was performed, revealing a 6.5 cm mass adherent to the deep flexor tendon and adjacent tissues. The cut section had cysts filled with blackened clotted material, which exuded reddish serous fluid. Microscopically, the cysts were filled with red blood cells and were either denuded or covered by synoviocytes. In addition, the mass was characterized by marked fibrovascular connective tissue associated with siderophages and multinucleated giant cells. These findings were consistent with those of pigmented villonodular tenosynovitis, a rare condition affecting several animal species and humans.

RESUMO: Uma cadela de 12 anos, sem raça definida, apresentou claudicação, algia e aumento de volume não ulcerado, de aspecto nodular, na região proximal à articulação do tarso do membro pélvico direito. A excisão cirúrgica foi optada e revelou uma massa de 6,5 cm de diâmetro, aderida ao tendão flexor profundo e aos tecidos adjacentes. Ao corte, exsudava líquido seroso avermelhado e cistos preenchidos por material coagulado enegrecido foram observados. Microscopicamente, a massa apresentava formações císticas frequentemente preenchidas por hemácias, que encontravam-se ora revestidas por sinoviócitos, ora desnudas. Havia ainda acentuada quantidade de tecido fibrovascular associado a siderófagos e células gigantes multinucleadas. Esses achados foram consistentes com tenossinovite vilonodular pigmentada, uma rara condição que afeta diversas espécies de animais e humanos.

Caracterización imagenológica de la sinovitis vellonodular pigmentada y el tumor de células gigantes de la vaina sinovial / Radiological features of pigmented villonodular synovitis and giant cell tumor of tendon sheath

OBJETIVO: Mostrar los hallazgos imagenológicos en la resonancia magnética (RM) de la sinovitis vellonodular pigmentada (SVP) y el tumor de células gigantes de la vaina sinovial (TCGVS), dado que son entidades que representan un diverso grupo de alteraciones en la proliferación de la sinovial. MATERIALES Y MÉTODOS: Entre mayo de 2011 y junio de 2013, se estudiaron en nuestra institución 25 casos con diagnóstico histológico de proliferación de la sinovial. Se destacaron los distintos tipos de presentación en imágenes a través de una RM 1.5 Tesla. Los resultados fueron analizados y comparados con la literatura. RESULTADOS: La RM mostró características similares para esta patología en todos los pacientes. No obstante, se distinguieron 4 patrones principales de presentación, dependiendo de la morfología, la localización de la lesión y las características radiológicas diferenciales. Estos fueron: como dominante, el tumor de células gigantes de la vaina sinovial (n = 10), todos de localización extraarticular; la sinovitis vellonodular pigmentada de localización bursal (n = 2); la sinovitis vellonodular pigmentada de forma intraarticular focal (n = 5); y la sinovitis vellonodular pigmentada difusa (n = 8). CONCLUSIÓN: La sinovitis vellonodular pigmentada y el tumor de células gigantes de la vaina sinovial se consideran entidades similares desde el punto de vista anatomopatológico. La RM fue de gran utilidad para objetivar tanto las características radiológicas comunes como las diferenciales. Estas últimas, junto con la localización, nos permitieron clasificar 4 patrones de presentación. Su reconocimiento posibilita un adecuado seguimiento de la patología y un óptimo manejo terapéutico.

PURPOSE: To show the resonance magnetic imaging (MRI) findings of pigmented villonodular synovitis (PVNS) and giant cell tumor of the tendon sheath (PVNTS), entities with similar histology but differences in clinical and some radiological manifestations. MATERIALS AND METHODS: We studied 25 cases with histologically benign synovial proliferation in intra and extraarticular location of the extremities. It highlighted with a 1.5T MRI unit the different types of images presentation. The results were analyzed and compared with the literature. RESULTS: MRI displayed very specific imaging features in all patients. However, we were able to distinguish 4 main patterns of presentation depending on the morphology, location of the lesion and radiological differential. These were: as dominant presentation, pigmented villonodular synovitis localized form (n=10); pigmented villonodular synovitis bursal form (n=2); pigmented villonodular synovitis focal (n =5); and pigmented villonodular synovitis diffuse (n = 8). CONCLUSION: Both pigmented villonodular synovitis as well as giant cell tumor of the tendon sheath are considered similar from the point of view of the histological findings. MRI was useful to objectify both radiological features in common, such as the differential, which along with the location, allow us to classify patterns into 4 individual presentations. This recognition involves adequate radiological evaluation and is important for optimal management.

A Case of a Giant Cell Tumor of Tendon Sheath in a Child / 대한피부과학회지

A giant cell tumor of tendon sheath is a slow growing benign soft tissue tumor that is known by a variety of names including fibrous histiocytoma of tendon sheath and fibrous xanthoma of the synovium. Clinically, it presents as a 1~3 cm firm, non-mobile, painless, nontender mass, and mostly occurs at interphalangeal joints of fingers. It shows female predominance and can occur at any age, but it is most common between the third and fifth decades and is rare in children. We now report the case of a 10-year-old girl with a giant cell tumor of tendon sheath on the toe.

Diagnostic value of MRI for giant cell tumor of tendon sheath / 上海第二医科大学学报

Objective To analyze the value of MRI in the diagnosis of giant cell tumor of tendon sheath(GCTTS). MethodsThe MR images of 21 GCTTS cases including 3 cases of recurrences were retrospectively evaluated.All were confirmed giant cell tumor of tendon sheath by surgery and pathology.All the patiens were examined by MRI,and 19 received contrast enhanced MRI.The characteristics of MRI presentations were explored.Results Of the 21 cases,17 were in diffuse form and 4 in localized form.On T1WI,the signal intensities of the giant cell tumor of tendon sheath almost equalled to those of skeletal muscle in 18 cases and were slightly lower than those of skeletal muscle in 3 cases.On T2WI,the signal intensities tended to range between those of skeletal muscle and fat in 7 cases,almost equalled to those of skeletal muscle in 12 cases,and were slightly lower than those of skeletal muscle in 2 cases.Of the 19 cases with gadolinium-enhanced images,17 showed inhomogeneous enhancement and 2 homogeneous enhancement,and all were observed with a fat suppression sequence on T1WI. Conclusion MRI is able to depict the characteristic internal signal of giant cell tumor of tendon sheath,which is a valuable for diagnosis,treatment and follow-up.

A Case of Giant Cell Tumor of Tendon Sheath on the Palm / 대한피부과학회지

A 36-year-old female presented with a 5-month history of an indurated asymptomatic nodule on the left palm. A skin biopsy was done and the histopathological findings were consistent with those of a giant cell tumor of tendon sheath (GCTTS). A GCTTS occurs in the tendon sheath of digits or in the joints of the extremities, and most commonly involves the distal fingers. However, palmar involvement of this tumor is unusual. We present a case of GCTTS on the palm.

A Case of Giant Cell Tumor of Tendon Sheath on the Right 3rd Toe / 대한피부과학회지

A 40-year old woman presented with a skin colored, multinodular, hard mass of 1.5x1.0cm and 1.0X1.0cm on the right 3rd toe for 20 years. Histopathologically, the tumor consisted of lobules of varied cellularity surrounded by dense collagen. Some areas were cellular and consisted of histiocyte-like cells, osteoclast-like giant cells, foam cells. Other areas were less cellular and consisted of spindle cells within hyalinized stroma, compatible with giant cell tumor of tendon sheath.

Pigmented Villonodular Synovitis of the Temporomandibular Joint: a case report / 대한이비인후과학회지

Pigmented villonodular synovitis is a benign proliferative disorder affecting the synovium. In 1941, Jaffe assembled under the common term of pigmented villonodular synovitis dissimilar lesions described by different names, that issuch as giant cell tumors of synovial tendon sheaths, actual pigmented villonodular synovitis, and villonodular bursitis. (Giant cell tumors of tendon sheaths, which may be localized, most often occurring in fingers, flexor tendons or interphalangeal joints, or diffuse, usually arising in the vicinity of large joints.) Involvement of the temporomandibular joint is very rare. (We report a rare case of pigmented villonodular synovitis of the temporomandibular joint that invaded the mandibular condyle. A 34-year-old man had a large left preauricular (parotid) mass for two years that he had focal facial nerve paralysis, temporal and zygomatic branches. The clinical appearance suggested a parotid tumor. At surgical exploration, a tumor was found to be severely adhered sion to the facial nerve and involving the temporomandibular joint. Histologically, Tthe resected specimen histologically was a proliferative lesion composed of epithelioid histiocytes, spindle cells, and multinucleated giant cells.) The appearance was typical of the family of lesions that includes pigmented villonodular synovitis, bursitis, and tenosynovitis . rewritten as follows: (Giant cell tumors of tendon sheaths, which may be localized, most often occurring in fingers, flexor tendons or interphalangeal joints, and spread to other parts after arising in the vicinity of large joints.) rewritten as follows: (A 34-year-old man had a large left preauricular (parotid) mass for two years and showed focal facial nerve paralysis in the temporal and zygomatic branches. The clinical appearance suggested a parotid tumor. Surgical exploration revealed a tumor that was severely connected to the facial nerve involving the temporomandibular joint. Histologically, the resected specimen was a proliferative lesion composed of epithelioid histiocytes, spindle cells, and multinucleated giant cells.)

A Case of Giant Cell Tumor of Tendon Sheath Developing on the Toe / 대한피부과학회지

The giant cell tumor of tendon sheath is a benign histiocytic proliferation of the articular, tendinous and peritendinous synovial tissue that has rarely been reported in the dermatologic literature. Its histopatholgic appearance is characterized by the presence of multinucleated giant cells, histiocyte-like cells, fibroblast-like cells, foamy cells, and hemosiderin. It usually occurs on the fingers, hands and wrists. We describe a case of giant cell tumor of tendon sheath developing on the toe.

Two Cases of Giant Cell Deficient Giant Cell Tumor of Tendon Sheath / 대한피부과학회지

Giant cell tumor of tendon sheath is the second most common tumor involving the hands. It usually presents as a slowly growing, lobulated, painless subcutaneous mass. Histologically, the tumor is composed, in variable proportion, of histiocytoid mononuclear cells, multinucleated giant cells, xanthoma cells, and collagenized stroma. Although numerous characteristic multinucleated giant cells are usually noticeable in the tumor, they may be difficult to find, or be entirely absent. We present two cases of giant cell tumor of tendon sheath in which giant cells was not and rarely found respectively.

Giant Cell Tumor of Tendon Sheath: A case Report

We report a case of giant cell tumor of the tendon sheath in a 36-year-old male, who presented an asymptomatic, firm, 1.0 × 0.8 × 0.4cm-sized nodule, involving the volar aspect of the distal phalanx of the right index finger about 1 year ago. Histopathologically, the enucleated lesion showed four lobules surrounded by thin connective tissue, each of which demonstrated the variable cellularity and the polymorphic cell population consisting of foam cells, spindle-shaped fibroblasts, histiocyte-like cells and multinucleated giant cells with heavy hemosiderin deposits near the periphery, in the collagenous stroma. He has done well with no recurrence during one year of follow-up since the operation.
