Background: Primary giant cell tumor of soft tissue, also known as soft tissue giant cell tumor of low malignant potential, is a rare soft tissue tumor located in both superficial and deep soft tissue. Histologically, these lesions bear a close resemblance to their bony counterparts, giant cell tumor of bone, with round to spindle-shaped cells intimately admixed with uniformly scattered.

Giant cell tumor of soft tissue (GCTST) has gained general acceptance as an uncommon but distinct primary soft tissue tumor since it was first described in 1972 In Diagnostic Pathology: Soft Tissue Tumors (Second Edition), 2016. Giant Cell Tumor of Soft Tissue (Left) Microscopically, giant cell tumor of soft tissue (GCTST) is identical to giant cell tumor of bone composed of mononuclear stromal cells and multinuclear osteoclastic giant cells that are evenly distributed throughout the tumor Background: Primary giant cell tumor of soft tissue, also known as soft tissue giant cell tumor of low malignant potential, is a rare soft tissue tumor located in both superficial and deep soft tissue. Histologically, these lesions bear a close resemblance to their bony counterparts, giant cell tumor of bone, with round to spindle‐shaped cells intimately admixed with uniformly scattered.
Diffuse Type Tenosynovial Giant Cell Tumor Biphasic Synovial Sarcoma; No epithelial lining of spaces : May have epithelial lined glands: Keratin negative : Keratin positive : Usually involves joint: Very rarely involves joint : Giant cells may be frequent : Giant cells infrequent : No ropy collagen : Ropy collagen frequent : Nuclei frequently. 3. Discussion. A Giant Cell tumor of soft tissue (GCT-ST) is a very rare tumor that resembles osseous GCT clinically and histologically , .It was first described in the literature by Salm and Sissons in 1972 , .They reported a case series of 10 benign primary soft tissue tumors , .In the same year, Guccion and Enzinger reported a 32 case series of the same characteristic soft tissue tumors but.
The use of soft tissue radiographic techniques and mammographic films was an extremely valuable diagnostic tool, although computed tomography and magnetic resonance imaging may be necessary in some cases.

Primary giant cell tumor of soft tissue (GCTST) arising in a finger is a rare event. We report a case of a 54-year-old man with a primary finger giant cell tumor that appeared histologically identical to giant cell tumor of bone This entity remains one of the most challenging lesions to recognize in the field of soft tissue pathology. In addition, Dr. Folpe describes the features of hyalinizing spindle cell tumor with giant rosettes and emphasizes the morphologic overlap between low-grade fibromyxoid sarcoma and hyalinizing spindle cell tumor

Author information: (1)Department of Pathology, İzmir Katip Celebi University Atatürk Training and Research Hospital, İZMİR, TURKEY Whereas most bone tumors have an extraosseous counterpart, only 13 cases of GCT in soft tissues had been published until 1998. Moreover, 64 new cases have been reported in three series. Nevertheless, most major reviews and textbooks do not consider this tumor as a specific entity and regard it as a low grade variant of malignant GCT of soft tissue

AIMS: Giant-cell tumour (GCT) of soft tissue (GCT-ST) is a primary soft tissue neoplasm that is histologically similar to GCT of bone (GCT-B) Giant cell tumor (GCT) of the soft tissue (GCT-ST) is a rare, unusual primary soft tissue tumor that is completely distinct from, and should not be confused with, any giant cell-rich tumor of bone or soft tissue. Currently, GCT-ST is included in the group of so-called fibrohistiocytic tumors of intermediate (borderline) malignancy
Similarly, epitheliod sarcoma is a relatively rare malignant tumor, accounting for only 1.4% of malignant tumors in a large study performed at the Armed Forces Institute of Pathology; however, this tumor accounts for 21%-29% of all soft-tissue malignancies in the hand and wrist of patients aged 6-25 years Updates on the cytogenetics and molecular genetics of bone and soft tissue tumors.

Giant cell tumor of bone (GCTB) is a locally aggressive subarticular tumor. Having recently reported that H3.3 G34W mutations are characteristic of this tumor type, we have now investigated the sensitivity and specificity of the anti-histone H3.3 G34W rabbit monoclonal antibody in a wide variety of tumors including histologic mimics of GCTB to assess its value as a diagnostic marker tenosynovial giant cell tumors. Chondroblastoma-like soft tissue chondroma may be confused with tenosynovial giant cell tumor due to a resemblance between the mononuclear cells of both lesions and the presence of multinucleated giant cells. However, metaplastic cartilage is rarely seen in tenosynovial giant cell tumor

Fibrosarcoma of Soft tissue is a malignant fibrogenic tumor that occurs in patients between 55-80 years of age. Diagnosis is made with a biopsy showing spindle-shaped cells with scant cytoplasm and indistinct borders with tissue that is organized in herringbone fashion. Treatment is usually wide local resection with radiation. Symptoms
Giant cell tumor of bone is a rare, aggressive non-cancerous tumor. It generally happens in adults between ages 20 and 40 when skeletal bone growth is complete. It usually develops near a joint at the end of the bone. The location of a giant cell tumor is often in the knee, but can also involve the bones of the arms and the legs Since 1978, MFH it was identified as the most common soft tissue sarcoma after Weiss and Enzinger published the first large series of tumors with those characteristics. Four different sub-types have been described: Storiform-pleomorphic, Myxoid, Giant cell and Inflammatory Incidence and demographics of giant cell tumor of bone in The Netherlands: First nationwide Pathology Registry Study. all pathology excerpts were retrieved for patients diagnosed with GCT-B, giant cell tumors of tenosynovium, and giant cell tumors of soft tissue between January 1, 2009 and December 31, 2013. The incidence of GCT-B was. Giant cell tumor of soft tissue originally described in 1972 in two different series by Salm and Sissons is a rare entity, which is clinically and histopathologically indistinguishable from giant cell tumor of bone. Usually involve thigh, trunk, and lower extremities but rarely involve the hands. GCT-ST is a benign tumor, which can transform into malignant form and also has potential for.
Here's your ideal reference on the diagnosis of tumors of the skeletal muscles, connective tissue, fat, and related structures. No other textbook matches its scope and depth of coverage in this complex and challenging area of surgical pathology, and no other text contains as much practical information on differential diagnosis. Throughout, microscopic findings are correlated with the latest. Liposarcoma is one of the most commonly diagnosed soft tissue sarcomas, accounting for approximately 12.8% of all sarcomas. Most patients are older than 50 years of age and most patients complain of a large, painless, deep-seated mass usually located proximally in the extremities
