Study Design Case report. Objective Myeloid sarcoma (also known as chloroma) is a rare, extramedullary tumor composed of immature granulocytic cells. It may occur early in the course of acute or chronic leukemia or myeloproliferative disorders. Spinal cord invasion by myeloid sarcoma is rare. The
Acute myeloid leukemia (AML) is the most common leukemia in adults. According to the French-American-British (FAB) system, monocytic leukemia is classified as M5. Myeloid sarcoma further occurs in 3-5% of AML. This is defined as an extramedullary tumor of myeloid cells in the lymph BACKGROUND
The medical literature on synovial sarcoma (SS) of the head and neck region is limited. Thus, we determined whether clinical characteristics and treatment were associated with recurrence and survival rates in patients with SS of the head and neck.
METHODS

Milwaukee Shoulder Syndrome (MSS) is a painful progressive arthropathy in which hydroxyapatite crystal deposition in synovial tissue induces lysosomal release of collagenase and neutral proteases. These enzymes are destructive to periarticular tissue, including the synovium, articular cartilage,
OBJECTIVE
Atlantoaxial tumors account for a substantial proportion of primary bone tumors in children. Before resection, surgeons must consider the complex regional anatomy, the potential for neurological compromise, craniocervical instability, and the question of tumor resectability in a growing
Radiation-induced neoplasms of the central nervous system generally present as meningioma or sarcoma. Spinal cord glioma after radiation therapy is rare and half of the cases documented occurred after treatment of Hodgkin's disease.A 39-year-old male presented with a 1-month history of gradually

BACKGROUND
Primitive neuroectodermal tumor (PNET) is a malignant neoplasm that generally arises from bone and soft tissues, with predilection for young adults. This neural crest origin tumors share biologic and histologic features with Ewing's sarcoma (ES).
METHODS
We present a case of a 22-year-old
C2 vertebral body (axis) lesions are often approached anteriorly combined with posterior stabilization of craniovertebral junction (CVJ). The anterior approach has its limitations. A posterolateral corridor is an alternative access to the C2 body lesions, and this alone may suffice in
