GIANT-CELL TUMOR: A STUDY OF 195 CASES DAVID C. DAHLIN, MD, ROGER E. CUPPS, MD, AND EINER W. JOHNSON, JR, MD This study of 195 patients with giant-cell tumor reemphasizes the female pre- dominance, the predilection for the region of the knee, and the extreme rarity of the tumor in patients with immature skeletons. Sheets of rounded or polygonal cells blend with hypocellular collagenized zones; variable numbers of giant … Microscopic examination showed a tumor composed of numerous multi-nucleated giant cells admixed with the mononucleated stromal cells. Keywords: Cytology, Equine, Giant cell tumor of soft parts, Histopathology. The histopathologic appearance of the lesions was similar to that of osseous giant cell tumors. Giant multinucleated cells, mostly localized close to collagen bundles, can also be revealed. The multinucleated giant cells appear similar to osteoclasts, which led to the older term osteoclastoma ( 2 ). Giant cell tumors combined with secondary aneurysmal bone cysts are more likely to develop postoperative recurrence: A retrospective study of 256 cases. Soft tissue of this tumor is typically pinkish-tan. The location of a giant cell tumor is often in the knee, but can also involve the bones of the arms and the legs, or the flat bones such as the breastbone or pelvis. The classic text on the Mayo Clinic's experience with bone tumors, Dahlin's Bone Tumors presents a succinct, profusely illustrated summary of the largest single collection of well-diagnosed bone tumors anywhere in the world. Engulfed crystals are, differently, evidentiated by electron microscopy, both in mono- and multinucleated cell cytoplasm. Giant cell tumor (GCT) of long bone and central giant cell granuloma (CGCG) of the jaw show similar microscopic features. 2011 Feb. 469 (2):591-9. . Sheets and fascicles of markedly anaplastic spindle to ovoid cells. The tumor is generally benign and characterized histologically by multinucleated giant cells with a background of mononuclear stromal cells. 50-65% of tumours occur in the region of the knee [2]. A giant cell tumor is one that is made up of a large number of benign (noncancerous) cells that form an aggressive tumor. Giant cell tumor of bone (GCTB) is a locally aggressive and rarely metastasizing intermediate tumor, 1 with incidence of about 6% of all primary bone tumors in one institutional review. Note: Several types of giant cell tumours exist. Variable numbers of … Designed with the practicing clinician in mind, Biologics in Orthopaedic Surgery provides a succinct, easy-to-digest overview of the integration of biologics (platelet-rich-plasma [PRP], bone marrow aspirate [BMA], and stem cells) into ...

Giant cell malignant fibrous histiocytoma. The present study aimed to investigate the value of magnetic resonance imaging (MRI) in the diagnosis of giant cell tumor of the tendon sheath (GCTTS), including localized (L‑) and diffuse (D‑) types. Giant cell tumor of tendon sheath (GCTTS) is a benign slow growing tumor with a high incidence of recurrence. A case of giant cell tumor and a review of the clinical and pathologic records of 111 patients are discussed. Discussion. Diagn Cytopathol 30:14-8,2004. Note: The lesion is sharply demarcated from normal bone, but the margin is very thin. Originally, the patient presented with severe pain in the lumbosacral region, radiating posterolaterally from the lumbar spine into the bilateral thigh and subsequently, into the bilateral crus posterolaterally. Typical microscopic appearance of a giant cell tumor of the tendon sheath. A giant cell tumor is one that is made up of a large number of benign (noncancerous) cells that form an aggressive tumor.

Giant cell tumor is a locally aggressive neoplasm of uncertain origin which affects predominantly the epiphysis of long bones. It is so called because the tumor is predominated by the presence of multinucleated osteoclast like giant cells. It was also referred to as osteoclastoma for the same reason. First recognized in 1818 , it was not until 1940 that GCTB was formally distinguished from other nonmalignant tumors of bone, such as aneurysmal bone cyst, chondroblastoma, and nonossifying fibroma . >10 in the plane of section). The current report describes the case of a 29‑year‑old female with a sacral giant cell tumor (GCT) during pregnancy. Bone and Soft Tissue Pathology: A Volume in the Diagnostic Pathology Series, by Andrew L. Folpe, MD and Carrie Y. Inwards, MD, packs today's most essential bone and soft tissue pathology know-how into a compact, high-yield format! The morphological features, as demonstrated by electron microscopy, of a rare pancreatic neoplasm indistinguishable from giant cell tumor of bone by light microscopy is presented. 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. A malignant giant cell tumor that develops in a previously benign giant cell tumor is characteristically radioresistant. A tenosynovial giant cell tumor has a characteristic appearance when examined under a microscope. Giant-cell tumor of the bone (GCTOB), is a relatively uncommon tumor of the bone. Microscopic Features. The tumor is generally benign and characterized histologically by multinucleated giant cells with a background of mononuclear stromal cells. Mayo Clinic reported GCTB included approximately 5% of bone primary tumors. A total of 38 patients with GCTTS, including 31 with L‑GCTTS and 7 with D‑GCTTS, diagnosed by surgery and pathology, were retrospectively analyzed. The objective of this study was to review a series of cases in our department and to determine any clinical or pathological features that might predict the likelihood of recurrence. Aims/background: Giant cell tumour of the tendon sheath (GCTTS) is regarded as the most common neoplasm of the hand that can recur after excision. Two cases of a previously undescribed tumor were studied. Found insideHigh-quality illustrations capture key morphologic patterns for a full range of common and rare tumor types, and a "visual index" at the beginning of the book directs you to the exact location of in-depth diagnostic guidance. Having afterwards been granted a fellowship to extend his knowledge of bone pathology at the Rizzoli Orthopedic Institute of Bologna under the direction of Professor Vittorio Putti, he complemented this work with the study of clinical ... Giant cells are predominantly osteoclast-like, but atypical tumor giant cells can also be present. We report the clinical and roentgenographic manifestations of 14 patients with pathologically proven giant cell carcinoma of the lung, and compare our data to other reports in the literature. The histopathologic appearance of the lesions was similar to that of osseous giant cell tumors. Herein, we report a rare case of a nine-year-old girl with a hemorrhagic giant cell tumor of the left occipital skull base. 4, 5 GCTB usually … This book reflects the experience of the Rizzoli Orthopedic Institute during more than 100 years of treatment of musculoskeletal tumor and tumorlike lesions. Giant cell tumors of the tendon sheath are the second most common tumors of the hand, with simple ganglion cysts being the most common. Light (LM) and electron microscope (EM) observations from a number of tissue fragments allowed the identification of tumor nature, which appeared a giant cell tendon sheath. In cats, peripheral giant cell granulomas (giant cell epulis) are the second most common gingival tumor (28.8%) after fibromatous epulis (57.7%).The reported range for age of onset is 4-19 years. have prominent nucleoli. In both instances, angiography demonstrated hypervascular masses with arterial and venous abnormalities indicative of an aggressive malignancy. There is a slight female preponderance in localized TGCT; however, in diffuse TGCT, there is no sex predilection. It usually develops near a joint at the end of the bone. Hemorrhagic cystic (ABC) regions are present. 1. Two cases of malignant giant cell tumor originating within the soft tissues of the thigh are reported. Found insideThe number of cases compiled at the Latin American Registry of Bone Pathology increased from 4913 primary bone tumors and more than 1100 tumorlike lesions at the time of publication of the first edition of this book, to 5274 bone tumors and ... . These tumors are characterized by the presence of giant cells, which are large cells that typically contain more than one nuclei (the part of a cell that houses genetic material). Giant cell tumors are rare benign lesions that typically occur at the epiphyses of long bones in the extremities and present with pain or swelling. In these areas, the tumor resembled giant cell tumor of bone. Most published articles on primary malignancy in giant cell tumor of bone (PMGCTB) report a small number of cases. It is characterized by the presence of multinucleated giant cells (osteoclast -like cells). Giant cell tumor of the left ring finger metacarpal bone. They usu- ally appeared well-encapsulated, and commonly lobu- … Giant cell tumor of the tendon sheath (GCTTS) also called by the name of fibrous histiocytoma of synovium, pigmented nodular synovitis, tenosynovial giant cell tumor, localized nodular synovitis, benign synovioma, and fibrous xanthoma of synovium.
