osteoid

 [os´te-oid]
1. resembling bone.
2. the organic matrix of bone; young bone that has not undergone calcification.
osteoid osteoma a benign hamartomatous lesion of cortical bone in young persons. There are small sclerotic bone-forming areas visible on technetium diphosphate bone scan. The small central nidus produces large amounts of prostaglandin. There is often night pain, which may be responsive to nonsteroidal antiinflammatory drugs. Lesions may be excised in toto or may be treated with nonsteroidal antiinflammatory drugs, and often undergo involution in 5 to 7 years.

osteoma

 [os″te-o´mah]
a tumor, benign or malignant, composed of bony tissue; a hard tumor of bonelike structure developing on a bone (homoplastic osteoma) or other structures (heteroplastic osteoma).
Symptoms. Symptoms of bone cancer are pain, swelling, and disability in the area of the diseased bone. The pain at first is mild, stops and starts again, and then becomes increasingly severe. Swelling may appear soon after the first signs of pain, but often it cannot be seen until later. The disability may affect a nearby joint, such as the knee, shoulder, or hip. There may also be a hard, painful lump over which the skin moves freely. The skin temperature in the area may be slightly elevated.
Diagnosis and Treatment. Diagnosis of bone tumor is made after examination of x-ray film and a microscopic study of the suspected tissue. Malignant tumors can be treated by radiotherapy and surgery during the early stage of development. The prognosis for these tumors is grave, however. Hormone therapy and medication can also be helpful in certain types of the disease.
osteoma cu´tis progressive dermal ossification during childhood, with development of hard, round to irregular nodules representing islands of heterotopic bone within the dermis or subcutis, followed by coalescence of the lesions into plaques, and later by invasion of ossification into deep connective tissues. It may be sporadic or inherited as an autosomal dominant trait. Called also progressive osseous heteroplasia.
osteoma du´rum (osteoma ebur´neum) one containing hard bony tissue.
osteoma medulla´re one containing marrow spaces.
osteoid osteoma see osteoid osteoma.
osteoma spongio´sum (spongy osteoma) one containing cancellated bone.

os·te·oid os·te·o·ma

[MIM*259550]
a painful benign neoplasm that usually originates in one of the bones of the lower extremities, especially the femur or tibia of adolescent and young adult persons; characterized by a nidus (usually no larger than 1 cm in diameter) that consists of osteoid material, vascularized osteogenic stroma, and poorly formed bone; around the nidus there is a relatively large zone of reactive thickening of the cortex.

(os'tē-oyd os'tē-ō'mă)
A painful benign neoplasm that usually originates in one of the bones of the lower limbs, especially in adolescents and young adults; characterized by a nidus of osteoid material, vascularized osteogenic stroma, and poorly formed bone; around the nidus there is a relatively large zone of reactive thickening of the cortex.
