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

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

General Principles On initial evaluation, any lesion is more likely to be a common rather than a rare condition. The most com-mon soft-tissue lesion in the hand and wrist is a ganglion; the most common bone tumor is an enchon-droma
  2. Giant cell tumor of bone (GCTB) is a rare, benign primary bone tumor that commonly occurs in young adults. It accounts for approximately 5% of all primary bone tumors and approximately 20% of all benign bone tumors [1-5].Though categorized as a benign skeletal tumor, GCTB is also known for its locally aggressive behavior and high recurrence rates; 15%-50% after usual curettage only, and 2.

  5. The size of GCTs was larger than average: 2.1 cm in our study compared with 1.2 cm and 1.85 cm in other large series. 1, 4 This propensity toward larger size in soft tissue tumors has been noted before with averages of 3.8 cm and 4.6 cm in two smaller cases series. 5, 9 Larger tumor size has also been shown to correlate with a worse outcome. 10.
