RESUMEN

Hemangiopericytoma of the bone is a rare malignant tumor, which usually originates in the femur and the pelvic bone of the adult. Heman-giopericytoma is often not a primary tumor but a secondary tumor associated with extraskeletal metastasis. We experienced a case of hemangiopericytoma, which originated from the retroperitoneum and had multiple metastasis to the scapula, proximal femur, cervical spine, and which converted from low grade to high grade.

RESUMEN

A 21-year-old male had have a one-year history of persistent left hip pain that was aggrevated at night. The diagnosis was osteoid osteoma that was based on clinical examination, simple radiography, and computed tomography. Under spinal anesthesia, the tumor was localized using an image intensifier and its nidus was excised successfully using the burr down technique. We report upon a single case of arthroscopic excision of an osteoid osteoma using the burr down technique and the good result obtained at the 2 year follow-up.

RESUMEN

Pigmented villonodular synovitis is a slow, usually monoarticular, progressive proliferative disorder of uncertain etiology involving joint tissue, tendon sheath, and bursae. Pigmented villonodular synovitis has been divided in two forms-diffuse and localized. Localized pigmented villonodular synovitis of the knee joint can present with symptoms of pain, locking and instability. We report a case of a patient who presented with symptoms of recurrent subluxation of patella due to a localized pigmented villonodular synovitis occurring in the medial patellofemoral joint.

RESUMEN

Vascular leiomyoma or angioleiomyoma is a uncommon benign solitary tumor that arises from the tunica muscularis of blood vessels. It is usually located in the wall of the uterus. It may present with a confusing picture of hand pain and paresthesia or be asymptomatic. We describe a 49-year-old man who presented with a slowly growing mass in the volar region of wrist which, on histological examination, was shown to be a vascular leiomyoma. It is not usually included in the differential diagnosis of anterior wrist mass or median nerve tumors.

RESUMEN

Synovial cysts are uncommon lesions that may occur within the spinal canal. Most commonly synovial cysts arise from degenerative apophyseal joints, in particular at the L4-5 level, and are associated with spondylolisthesis. We present one case of lumbar synovial cyst located both intraspinally and extraspinally and originated from the defect of the pars interarticularis. The content of the synovial cyst was infected. The patient progressively developed low back pain and fever. The lesion was diag nosed by computed tomography and a magnetic resonance imaging. The synovial cyst was presented a huge lobulacted intraspinal and extraspinal mass and connected with the L4-5 facet joint on the right side. The dural sac was displaced by the intraspinal mass. Relieve of symptoms was achieved with decompressive laminectomy and removal of the mass. The content of the synovial cyst was infected with Staphylococcus aureus confirmed by the synovial fluid culture. The reasons for our report are to describe the previously unreported appearance of this lesion that was huge lobulated intraspinal and extraspinal mass with infected fluid content originated from the defect of the pars interarticularis.
