Osteochondromas are common and typically arise from the metaphyseal ends of long bones. An osteochondral neoplasm of the soft tissue, which is a lesion of uncertain pathogenesis, is uncommon and usually arises from the synovial tissue in joints and tendon sheaths. Rarely, extraskeletal osteochondromas also arise outside of synovial compartments. ⋯ It consisted of sharply demarcated, mature hyaline cartilage that was covered with a fibrous capsule, which changed gradually into cancellous bone, more pronouncedly at the center. The diagnosis of an extraskeletal osteochondroma should be considered when a discrete, ossified mass is localized in the soft tissues. A case of pathologically proven extraskeletal osteochondroma of the buttock is presented with a literature review, magnetic resonance imaging, and radiological findings.

Case ReportsCervical epidural abscess secondary to aorto-duodenal fistula: a case report.
Although cervical epidural abscess is rare, it should be strongly suspected in any patient with unexplainable neck pain and fever, especially when the patient has a predisposing factor for this infectious process. The authors report a case of cervical epidural abscess in a 39-yr-old man with an aorto-duodenal fistula, which complicated the interposition of artificial graft for abdominal aortic aneurysm rupture, which had undertaken 40 months before. Timely detection and intervention rendered him a full neurological recovery. This extremely rare case is presented with a literature review.
