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·o·ma

(os'tē-ō'mă),
A benign, slow-growing mass of mature, predominantly lamellar bone, usually arising from the skull or mandible.
[osteo- + G. -oma, tumor]

osteoma

/os·te·o·ma/ (os″te-o´mah) a benign, slow-growing tumor composed of well-differentiated, densely sclerotic, compact bone, occurring particularly in the skull and facial bones.
compact osteoma  a small, dense, compact tumor of mature lamellar bone with little medullary space, usually in the craniofacial or nasal bones.
osteoma cu´tis 
1. formation of bone-containing nodules in the skin.
2. progressive dermal ossification during childhood, with development of islands of heterotopic bone within the dermis or subcutis, coalescence of the lesions into plaques, and invasion of ossification into deep connective tissues.
osteoma du´rum , osteoma ebur´neum compact o.
ivory osteoma  compact o.
osteoma medulla´re  one having marrow spaces.
osteoid osteoma  a small, benign but painful, circumscribed tumor of spongy bone, usually in the bones of the limbs or vertebrae of young persons.
osteoma spongio´sum , spongy osteoma one having cancellated bone.

osteoma

A BENIGN tumour of bone, largely confined to the skull and jawbone. Osteomas often arise in a sinus or in the ORBIT, are slow-growing and can be removed if causing cosmetic or other problems.

osteoma

benign, slow-growing, bone neoplasm

osteoma (os´tēō´mə),

n a benign neoplasm of bone or bone tissue.

osteoma

a benign tumor composed of bony tissue. In animals seen most commonly on jaws and in the nasal sinuses of horses and cattle. Histologically similar to ossifying fibroma, fibrous dysplasia, heterotopic ossification and exostosis.

osteoid osteoma
a small, benign but painful, circumscribed tumor of spongy bone, occurring especially in the bones of the extremities and vertebrae in humans. Similar lesions have been reported in cats.
osteoma spongiosum
one containing cancellated bone.
