Telangiectatic osteosarcoma histology

Telangiectatic Osteosarcomas are rare, malignant, high-grade osteosarcomas that occur most commonly in the proximal humerus, the femur, and proximal tibia. Patients typically present between the ages of 5 and 25 with regional pain and swelling Abstract Osteosarcoma is one of the most common primary malignant bone tumors in children and adolescents. Telangiectatic osteosarcoma is an unusual variant of osteosarcoma, forming 3% to 10% of all osteosarcomas. Radiographically, these tumors appear as purely lytic destructive lesions located in the metaphyses of long bones Ovarian sarcoma with histologic features of telangiectatic osteosarcoma of the bone. Hirakawa T(1), Tsuneyoshi M, Enjoji M, Shigyo R. Author information: (1)Second Department of Pathology, Faculty of Medicine, Kyushu University, Fukuoka, Japan. A primary osteosarcoma occurred in the left ovary of a 47-year-old Japanese woman Purposes: Telangiectatic osteosarcoma (TOS) is a rare subtype of osteosarcoma. We analyzed (1) oncologic outcome in a large homogeneous series and (2) the role of prognostic factors on prognosis, local recurrence and metastasis

Telangiectatic osteosarcoma is extremely lytic on X-rays. It demonstrates very little osteoid production. It is characterized by cystic spaces filled with blood that are separated by thin septa. It is a cancerous tumor largely composed of cystic cavities containing necrosis and hemorrhag Telangiectatic osteosarcomas are usually osseous in origin and occur in the medullary cavity in the metaphyseal region of long bones. The most frequently affected site for these tumors is the distal femur, which accounts for 48% of cases. Another common location is the proximal humerus Telangiectatic osteosarcomas (TOS) are an uncommon variant of osteosarcoma that represent 2.5-12% of all osteosarcomas Telangiectatic osteosarcoma shows dilated blood-filled spaces lined or traversed by septa containing atypical stromal cells, with or without production of a lacelike osteoid matrix

Telangiectatic osteosarcoma appears as a painful, radiographically lytic mass lesion in the metaphyseal portion of the long bones. It is characterized by dilated, blood-filled vascular spaces lined.. Telangiectatic osteosarcoma is characterized by dilated, blood-filled vascular spaces lined by malignant osteoblasts. These osteoblasts are separated by fibrous septa, which contain the malignant cells, multinucleated giant cells, and tumor osteoid. Malignant cells are noted in a background of blood and necrotic debris Telangiectatic osteosarcoma is a rare and special variant of osteogenic sarcoma with distinct radiologic, gross and microscopic features. This tumor is predominantly lytic, destructive tumor without sclerosis on roentgenogram, and is soft and cystic on gross examination

After being clinically free of disease for seven years, the patient developed a 23 cm mass involving his small bowel wall. To our knowledge, this is the largest reported case of metastatic osteosarcoma involving the small intestine. The metastasis was that of a conventional high-grade osteosarcoma with telangiectatic features Advances in diagnosis and chemotherapeutic regimens have improved the prognosis of patients with telangiectatic osteosarcoma. [6, 14, 41, 42, 43] Because of neoadjuvant chemotherapy, the continuous disease-free survival for patients with telangiectatic osteosarcoma is similar to or better than that for persons with conventional osteosarcoma.[14, 41, 44, 45 Telangiectatic osteosarcoma. Telangiectatic osteosarcomas are vascular tumors that produce a small amount of osteoid. On x-ray, they appear as destructive lesions that can sometimes be confused with other types of tumors.

Background: Telangiectatic osteosarcoma (TOS) is a rare type of osteosarcoma for which limited clinical data is available.Furthermore, the clinical characteristics and prognosis of TOS remain unclear. Methods: A large population-based cohort analysis was conducted using the Surveillance, Epidemiology and End Results (SEER) registry.The data of TOS and conventional osteosarcoma (COS) patients. In a series of 105 cases of aneurysmal bone cyst, 18 showed an unusually high level of mitotic activity and/or increased nuclear pleomorphism which complicated the differential diagnosis with respect to telangiectatic osteosarcoma. An attempt was made to use semi-automatized morphometric and histophotometric techniques to establish objective morphological differences between these unusual.

Telangiectatic Osteosarcoma: Background, Etiology

Primary bone tumors are rare, but osteosarcoma (OS) is the fourth commonest non-hematological primary neoplasm of the bone in the adolescence, and the other three commonest neoplasms, in descending order, are leukemia, brain tumors, and lymphoma. The commonest presenting complaints are swelling and aches. These tumors cannot be diagnosed without the help of radiology Osteosarcoma (OS) is a common primary malignant tumor of bones that produces osteoid matrix. Telangiectatic osteosarcoma (TOS) is a rare variant of OS. It affects the long bones especially the lower end of femur and the upper ends of tibia and humerus, a distribution similar to the conventional osteosarcoma. The rib involvement is very infrequent Osteosarcoma pathology was classified as NOS for 67% of cases. Otherwise, chondroblastic (10.5%) was the most common osteosarcoma pathology followed by fibroblastic (9.4%), parosteal (8.7%), and telangiectatic (2.2%), and the other pathology subtypes made up <1% of all cases Telangiectatic osteosarcoma (TOS) is a high-grade variant of osteosarcoma, with a rapidly progressive course. It was first described by Paget in 1854 [ 8 ]. It accounts for about 9% of high-grade osteosarcoma with male sex preponderance and mostly occurs in younger age group between 10 and 20 years [ 3 ]
