Overview on Bone Sacral Tumors
نویسنده
چکیده
Primary sacral tumors are rare, accounting for approximately 5–7% of all spinal tumors [1]. Metastases are the most common malignant tumors of the sacrum and can be derived from lung, breast, kidney, prostate, head and neck, gastrointestinal, or skin (melanoma) cancers [2, 3, 62]. Primary benign and malignant tumors of the sacrum may arise from bone or neural elements or the bone marrow in cases of hematological malignancies. Approximately 10% of all benign tumors or pseudotumors have been known to involve the sacrum. These can include giant cell tumors (60% of cases), aneurysmal bone cysts (4%), and osteoblastomas. Of malignant bone tumors, 6–8% involve the sacrum and include chordoma (50%), lymphoma (9%) and multiple myeloma (9%), Ewing’s sarcoma in children (8%), chondrosarcoma in adults, and osteosarcoma [4].

Cutaneous Metastasis from Sacral Chordoma: A Case Report
Chordoma is a malignant, slow growing and locally aggressive tumor. It arises from remnants of the notochord and accounts for 1–4% of all primary bone tumors. They usually arise from anywhere along the spine, from base of the skull to the sacrococcygeal area and usually do not metastasize. Chordomas are slow-growing tumors which are not responsive to conventional chemotherapy or radiation. They...

canal tumors and, most commonly, metastases. The most common primary malignant bone tumor is chordoma, and the second most common is giant cell tumor. The presence of multiple lesions involving the sacrum and other bones suggests metastasis or multiple myeloma. Although the imaging findings of sacral tumors are nonspecific, a patient’s age and sex, and specific findings such as calcification or...
متن کاملGiant Cell Tumor of Bone - an Overview
Giant Cell tumors (GCT) are benign tumors with potential for aggressive behavior and capacity to metastasize. Although rarely lethal, benign bone tumors may be associated with a substantial disturbance of the local bony architecture that can be particularly troublesome in peri-articular locations. Its histogenesis remains unclear. It is characterized by a proliferation of mononuclear stromal ...

Chordoma is a primary sacral neoplasm of ectodermal origin and makes up %1- 4 of all primary bone tumors. It is usually present on the midline cerebrospinal axis and the most common locations are the spheno-clival region and the sacrum. The treatment of primary sacral tumors represents a challenge because of a large tumor mass at presentation and a hemorrhage risk in surgery. Sacral tumors may ...
