The topic Juxtacortical Osteosarcoma you are seeking is a synonym, or alternative name, or is closely related to the medical condition Parosteal Osteosarcoma.

Quick Summary:

• Osteosarcoma forms a class of highly-cancerous, high-mortality, bone tumor. After multiple myeloma, it is the second-most common primary tumor of the bones
• Parosteal Osteosarcoma is a slow-growing, rare bone tumor arising from the cortical surface of the bone. Hence, these are malignant bone tumors
• The tumor occurs over the metaphyseal region, especially the long bones, near the knees. The most common location is the posterior aspect of distal femur (thigh bone), in approximately 70% of the cases
• Parosteal Osteosarcoma presents as a mass with signs and symptoms that include pain and decreased joint movement
• The exact cause of the condition is unknown and presently, it is not possible to prevent Parosteal Osteosarcoma occurrence
• A treatment of this bone tumor may involve surgery, chemotherapy, and radiation therapy. The prognosis of Parosteal Osteosarcoma depends on the stage of cancer; higher grade osteosarcomas indicate a poorer prognosis

Osteosarcomas are classified in several different ways. They may be classified based on their cause/origin, location, or even based on certain diagnostic findings.

Based on where they occur, Osteosarcoma is classified as Medullary Osteosarcoma (occurring in the bone cavity) and Surface Osteosarcoma (occurring on the bone surface).

• Medullary Osteosarcomas are of several different types, and these include:
  • Conventional Osteosarcoma
  • Osteosarcoma of Jaw Bones
  • Post-Radiation Sarcoma
  • Osteosarcoma arising in Paget's Disease of Bone
  • Osteosarcoma in other Benign Conditions
  • Telangiectatic Osteosarcoma
  • Small Cell Osteosarcoma
  • Low-Grade Osteosarcoma
  • Multicentric Osteosarcoma
• Surface Osteosarcomas are of several different types, and these include:
  • Parosteal Osteosarcoma
  • Periosteal Osteosarcoma
  • High-Grade Surface Osteosarcoma
