Striatumoma
Introduction
Introduction to striate osteoma Osteopathiastriata is characterized by a dense shadow of banded or striped shape on the bone, especially at the metaphyseal end of the long bone. Osteoma often occurs in the osteogenesis of the membrane, most commonly seen in the craniofacial bone, called osteosarcoma; occasionally see soft tissue, it is called extra-osseous osteoma, intramedullary osteoblasts can stop growing as the bone matures. And no malignant, its prognosis is generally good, however, cervical vertebrae are rare. In addition, multiple osteoma, such as intestinal polyposis, is called Garder syndrome, the disease is hereditary, osteoma is a benign tumor caused by abnormal proliferation of bone tissue caused by abnormal periosteal osteogenesis, it is not a real tumor, and It is a hamartoma, and it is also considered to be a dense proliferation of bone tissue abnormalities. basic knowledge Sickness ratio: 0.0001% Susceptible people: infants and young children Mode of transmission: mother-to-child transmission Complications: congenital venous malformation limb hypertrophy syndrome
Cause
The cause of striated osteoma
(1) Causes of the disease
The reason is unknown. According to the literature, there are embryonic residues, trauma, infection, endocrine disorders and genetic theory, but more literature supports the tendency of embryonic residue theory - and it is believed that in the occurrence of the disease, tumors may occur at the junction of two different tissues. , various parts of the skull, or intramembranous osteogenesis, or endochondral ossification (in the occurrence of learning, the skull must undergo two stages of changes before ossification: 1 the mesenchymal thickening of the invading cerebral vesicle is a membrane 2, followed by transformation into cartilage, where the ossification of cartilage, for cartilage osteogenesis, such as the bones of the skull and the outer part of the sphenoidal wing, all the skull base bone, where the non-cartilage stage, directly by the membrane Occurrence of ossification is intramembranous osteogenesis, for example, all the skulls that form the cranial sac, except for a part of the occipital bone. The formation of the nasal cavity is basically an intra-chondral osteogenesis, so there is called intranasal osteogenesis. Occurs between the frontal bone and the ethmoid bone, between the sphenoidal wing and the frontal humerus or in the maxilla. The osteoma is derived from membranous tissue and develops into a rigid osteoma, derived from cartilage tissue. For cancellous osteoma, come at the same time To both organizers (above mandible), the development of hybrid osteoma.
(two) pathogenesis
Osteoma is a benign lesion that is more common in the skull and bones. It consists of osteofibrous fibrous tissue, osteoblasts and new bones produced by it. It contains well-differentiated mature bone tissue and has The obvious lamellar structure, the osteoma grows with the development of the human body. When the human body matures, most of the tumors also stop growing. The multiple osteoma is called Gardner syndrome, and there are intestinal polyps and soft tissue lesions.
The tumor bone is yellow-white, with bone-like hardness, uneven surface, covered with pseudo-envelope, microscopically composed of fibrous tissue and new bone, enlarged bone cells, uneven staining of the matrix, no malignant changes of fibroblasts and osteoblasts. phenomenon.
Prevention
Striatal osteoma prevention
Food is the material basis for the recovery of cancer patients. Paying attention to the diet of cancer patients and providing reasonable and sufficient nutrition can enhance the body's resistance, improve the patient's tolerance to treatment, ensure the successful completion of the treatment plan, and promote rehabilitation.
1. Avoid eating foods that contain carcinogens, such as vegetables containing nitrite-like strong carcinogens, moldy foods, pickled, smoked, grilled, and fried foods.
2, intake of rich protein, amino acids, high-vitamins, high-nutrition foods; eat more foods that are good for poison excretion and detoxification, such as mung beans, red beans, melon, watermelon and so on.
3, should eat more anti-bone tumor food: goat blood, scorpion, crab, sheep brain, sea cucumber, oysters, oysters, turtles, sand worms, deer blood, big leafy vegetables, oatmeal, small leeks, rapeseed, sand Jujube, citron, chestnut, wild grapes.
4, should eat foods that have the effect of relieving pain and swelling: asparagus, medlar, sage, hawthorn, clam meat, heron, crab, clam, sea turtle, sea snake.
5, avoid tobacco, alcohol. Avoid spicy and irritating foods such as onions, garlic, ginger, pepper, pepper, cinnamon and so on. Avoid fatty food.
6, bone tumor patients due to the mass in the torso limbs and other weight-bearing parts, once diagnosed often need to limit limb activity that is braking. Patients with bone tumors can be appropriately increased when they are in a period of rehabilitation after reasonable and effective treatment, but they should do their best and should not be overworked. Regular review, according to the specific circumstances, under the guidance of a doctor to carry out functional rehabilitation exercises.
Complication
Striatal osteoma complications Complications congenital venous malformation limb hypertrophy syndrome
In severe cases, the length of the limb may vary.
Symptom
Symptoms of striate osteoma Common symptoms Osteochondral bone disease Limb striate hypertrophy
Under the microscope, the streaks are agglutination of cancellous bone tissue, and there is no abnormal structure. The other components of the bone have no pathological expression.
Examine
Examination of striate osteoma
Asymptomatic, occasional mild pain in the joints, occasional unevenness of the limbs, but whether it is related to the disease is unknown.
X-rays are characteristic. On most bones of the whole body, linear or band-shaped dense stripes are visible, starting from the dry end, extending until the middle of the backbone is parallel to the long axis, and there is a decrease in density between the stripes. Areas, stripes can also enter the epiphysis, the skull, hands and clavicle are often inviolable, but the calcaneus and talus can be affected, the performance on the humerus is characteristic, from the upper acetabulum to the fan-shaped radial arrangement, sometimes It can also be plaque or speckled. The cortical bone is slightly denser than normal, but there is no damage. The density of this stripe can be gradually increased to occupy the entire metaphysis.
Its diagnosis relies entirely on the X-ray.
Diagnosis
Diagnosis and diagnosis of striate osteoma
diagnosis
The diagnosis relies entirely on X-rays, and most of them are accidentally discovered, and the streaks of the bones are also present in other diseases, including osteochondrosis (marble bone disease), abnormal cartilage (Ollier disease) and limb bones. Hypertrophy, fragile osteosclerosis and Englemann and other diseases.
Differential diagnosis
Should be distinguished from Ewing's sarcoma, chondrosarcoma.
Ewing's sarcoma: Pain is the most common clinical symptom of Ewing's sarcoma. About two-thirds of patients may have intermittent pain, varying degrees of pain, not serious at first, but rapidly becoming persistent pain; Different, local pain will spread with the spread of the tumor, such as occurs in the pelvic area, the pain can be radiated along the lower limbs, affecting hip joint activity; if it occurs in the long bone adjacent to the joint, there will be lameness, joint stiffness, and joint effusion, this Tumors rarely have pathological fractures. They are located in the spine and can cause radiation pain, weakness and numbness in the lower limbs. Localized masses appear as the pain increases. The mass grows rapidly and the surface can be red, swollen, hot, and painful. The tenderness is remarkable, the surface may have venous engorgement, and sometimes the lumps grow in the soft tissue. It can be enlarged in 2~3 months, which occurs in the tumor of the tibia. The mass can protrude into the pelvis and can be in the lower abdomen or anus. At the time of diagnosis, the tumor is touched. Systemic symptoms: Patients are often accompanied by systemic symptoms such as elevated body temperature of 38 to 40 ° C, general discomfort, fatigue, loss of appetite and anemia.
Chondrosarcoma: Primary chondrosarcoma is malignant at first, the majority of patients are younger than 20 years old, the symptoms are similar to osteosarcoma, local pain is severe, rapid development, rapid cachexia, poor prognosis, secondary chondrosarcoma Chondromatosis, chondroma or malformation osteitis malignant, patients with adulthood over 30 years old, mild symptoms, better prognosis.
