Tumors of Bone

Granulocytic Sarcoma in bone

Granulocytic sarcoma (GS) is a solid tumor of immature granulocytes that most commonly occurs in a patient with leukemia or some other myleoproliferative disorder. Osseous lesions are most common in the skull and the orbit.
Peak incidence occurs in the third and fourth decades of life.
The majority of osseous granulocytic sarcomas present with skeletal pain referable to the location of the lesion.The usual finding on radiographs is lytic destruction of the cortex and the medulla with adjacent soft tissue mass and periosteal reaction.

Hemangioma

Los hemangiomas son lesiones benignas del hueso caracterizada por espacios vasculares revestidos con células endoteliales. Aproximadamente el 50% de los hemangiomas óseos se encuentran en los cuerpos vertebrales (torácicos especialmente) y el 20% se encuentran en la bóveda craneal. Las lesiones restantes se encuentran en la tibia, fémur y el húmero.
La mayor incidencia ocurre en los años 50.
Los hemangiomas son generalmente asintomática, por lo general detectados de manera casual. La aparición en X-ray depende de la ubicación. Las lesiones son a menudo mal definido, que aparece como un área algo localizada de vasos abundante, dilatada, algunas de ellas pueden estar en la superficie del hueso, dentro de la corteza del hueso, o extenderse a la cavidad medular.

Hemangioma

Hemangiomas are benign bone lesions characterized by vascular spaces lined with endothelial cells. Approximately 50% of osseous hemangiomas are found in the vertebral bodies (thoracic especially) and 20% are located in the calvarium. The remaining lesions are found in the tibia, femur and humerus.
Peak incidence occurs in the 50s.
Hemangiomas are largely asymptomatic, usually found incidentally.Appearance on X-ray is dependent on location. The lesions are often poorly defined, appearing as a somewhat localized area of abundant, dilated vessels, some of which may be on the surface of the bone, within the cortex of the bone, or extend into the medullary cavity.

High-Grade surface osteosarcoma

High grade periosteal osteosarcoma (also known as high grade surface osteosarcoma) accounts for less than 1% of all osteosarcoma. The only difference between conventional osteosarcoma and high-grade per osteal osteosarcoma is the location of the latter on the surface of the bone.

High grade periosteal osteosarcoma appears malignant on plain x-ray. There is irregular cortical destruction as well as irregular periosteal reaction.
