Tenosynovial Giant Cell Tumor

Tenosynovial giant cell tumors (TGCTs) are typically benign neoplasms of the joint, bursa, and tendon sheath. Usually, TGCT presents as a small localized tumor on the hand and wrist. The diffuse-type TGCT is more aggressive and mainly affects large joints such as knees, hips, ankles, and elbows. Diffuse-type TGCT of small joints is rare. To our knowledge, this is a very rare case of a huge diffuse-type TGCT on the wrist. We report a huge TGCT, which grew gradually over 10 years.

Introduction Giant cell tumors of the tendon sheath (GCTTS) are very common. More recently, a small number of case reports have identified the presence of multifocal GCTTS in the hand. These case reports have identified the presence of a maximum of two simultaneous lesions of a giant cell tumor affecting the same tendon sheath. We present an exceptionally rare case of simultaneous multiple localized GCTTS in which five lesions were identified on a single tendon simultaneously. This number of lesions on a single tendon has never been previously reported. Case: A 37-year-old tree surgeon initially complained of pain in the region of the base of the ring and little fingers. A month later, he developed multiple soft tissue swellings at these sites and a soft tissue mass in the center of the palm relating to the left ring finger. A magnetic resonance imaging (MRI) scan suggested multiple GCTTS. These masses were excised completely without MRI evidence of a recurrence. Multiple GCTTS should be a differential diagnosis of multiple soft tissue swellings in the hand with an MRI scan and complete excision being the appropriate imaging and treatment modality respectively.

Tenosynovial Giant Cell Tumor

Diffuse-type tenosynovial giant cell tumor (TS-GCT) is categorized as a locally aggressive but non-metastasizing neoplasm according to the WHO classification. Herein, we report an extremely rare case of a 41-year-old woman who developed multiple metastases from diffuse TS-GCT with benign histological features. The patient complained of a painful buttock mass and imaging studies revealed a soft tissue tumor of the buttock and multiple pulmonary nodules. The buttock tumor was excised and the final diagnosis was extra-articular diffuse-type TS-GCT. By video-assisted thoracic surgery, pulmonary nodules were pathologically identical to the primary tumor. Residual pulmonary nodules progressively grew, and she developed a muscle metastasis and a subcutis metastasis. She died of respiratory dysfunction due to multiple pulmonary metastases 1 year after primary surgery. Very few reports on histologically benign metastases from TS-GCT have been published, and the natural course of this rare condition remains unclarified. This rare case could provide important information for further clinical evaluation of this tumor.

Tenosynovial Giant Cell Tumor

Introduction: Tenosynovial giant cell tumor (TSGCT) (synonym – pigmented villonodular synovitis) – is a rare benign proliferative lesion of the synovial sheath, localized in the joint capsule, bursa or tendon sheath and characterized by locally destructive growth. Depending on the prevalence within the joint elements, the presence of a capsule around the tumor, histophotographic features of cell structure and clinical behavior TSGCT can be divided to localized or diffuse type. The aim of the study was researching of histopathological properties of diffuse-type TSGCT, determine the parameters its morphological indicators and to find out the correlation between these morphological and clinical parameters. Materials and methods: The research material was used biopsy (resect) of pathological lesions from 50 patients who were diagnosed and histologically verified diffuse-type TSGCT. Microscopic examinations of the stained sections and their photo archiving were carried out with use of a Olympus-CX 41 light optical microscope. Group measurable parameters (mean values and Pearson tetrachoric index (association coefficient) were calculated in groups of comparison for morphological and clinical indices of TSGCT. The mean values were compared by Student’s test, P value of ≤0.1 was considered statistically significant. Results:Correlation analysis of indicators that accounted for the pairs of cases «clinic – morphology» revealed the relationships, that had the highest parameters of the association coefficient between such indicators: «presence of villous growths» - «severity of hemosiderosis» (if hypertrophied synovial villi available, with vascular injection and pronounced proliferation of synovial cells, there is also a significant accumulation of hemosiderin pigment); «presence of villous growths» - «type of predominant cellular proliferates» (if cells of TSGCT diffuse type consists of monotonous sheets of stromal cells, with uniform, oval to reniform nuclei, the proliferation of villi in synovial layer is non-distinctive); «presence of nodes» - «kind of stroma» (if nodes predominate, their histological structure is mainly represented by polymorphic clusters of synovitis cells in the form of cells, strands, chains, solid formations, among immature connective tissue with low hyalinosis); «cell size (area, cm²)» - «severity of haemosiderosis» and «cell size (area, cm²)» - «the number of multinucleated giant cells» (there is a pronounced deposition of pigment and accumulation of osteoclast-like multinucleated giant cells type, although usually their number is relatively small compared to the localized type of TSGCT). Conclusions: Morphological parameters, that we have identified, characterize pathological changes in the tissues of TSGCT; careful analysis of the frequency of their occurrence in the different comparison groups made it possible to establish intergroup differences and correlations between individual indicators, which were previously unknown or not obvious. Our study was determine to analyze of incidence rates and correlation relationships, revealed some previously unknown differences and dependencies that are important for understanding the pathogenesis, improvement of diagnosis and prognosis of diffuse-type TSGCT.

Tenosynovial Giant Cell Tumor

Tenosynovial giant cell tumors typically arise in the synovium of joints, bursae, or tendon sheaths. They may occur in an intra- or extra-articular location and can be divided into localized and diffuse types. The neoplastic nature of the lesion has been supported by a recurrent CSF1 gene rearrangement in a small subset of lesional cells, of which the most common fusion partner is COL6A3. Herein, we report a case of intramuscular localized tenosynovial giant cell tumor harboring a novel CSF1-CD96 fusion transcript, thus expanding the molecular profile of this tumor.

Diagnostic Pitfall

Diffuse-type tenosynovial giant cell tumor can rarely present as an entirely extra-articular mass, which can be misdiagnosed as a sarcoma especially when giant cells are absent, dominated by large dendritic mononuclear cells, and desmin expression is extensive.
