Enostosis, what is it?

Enostosis: what is it?

If the outgrowth is secreted as a tumor from the outside, then it is exostosis, inside the bone - enostose.

Enostoses or osteomas are benign tumor-like neoplasms in the form of nodules.

Treatment of femur enostosis is usually not carried out, because these tumorous formations do not pose a danger to the patient, and do not cause discomfort.

Enostoses can occur in any bones, but the vertebrae, iliac and femur are most often affected, and small nodules are in some cases determined in the phalanges of the fingers.

Important: nodal proliferation can develop in persons working with harmful substances (in particular - phosphorus) and not using personal protective equipment.

Enostoses with pronounced narrowing or disappearance of the medullary canal are observed in marble disease.

The specific nature of the structure of the enostosis allows us to establish the true cause of its occurrence and to begin the complex treatment of the underlying disease.

Often, the doctor appoints the patient diagnostic procedures, not suspecting the presence of enostoses.

If the process is widespread, then a diffuse thickening of the cortical layer and filling of the femur cavity with obliteration of the medullary canal develops.

In vivo recognition of an enostosis is possible only with the help of an X-ray study. Often, the nature of the disease is established according to the picture of the enostosis.

An enostose in the narrow sense can only be spoken of when it quantitatively clearly predominates over the adjacent localization of the pathological formation of bone substance.

Enostosis refers to random findings, because no clinical symptoms are not accompanied.

Its tissue gradually passes into the surrounding bone, and the boundary between them is not determined.

In long tubular bones, osteoma must be differentiated from organized periosteal calluses and osteochondromas with ebournection of cartilaginous capsules.

Typical localization of osteoid osteoma-bone of the lower limbs, their diaphysis and metaphysis. Approximately half of the tumors are found in the proximal metaphysis of the femur and in the tibia.

Characteristic for this tumor is the gradual increase of soreness in the lesion. Soft tissue over the affected bone is edematous and painful. Hyperostosis is an osteosclerosis plus an increase in volume, a thickening of the bone.

This state is directly opposite to atrophy.

Enostosis, osteoma... osteoid osteoma: briefly as a matter of fact

The destruction of a bone is the destruction of a bone with its replacement by some abnormal tissue, which is manifested on the roentgenogram by enlightenments of various manifestations.

Depending on the nature of the bone replacement pathological tissue, the destruction is divided into inflammatory, tumor, degenerative dystrophic and destruction from substitution by a foreign substance.

Specific inflammatory destruction is tuberculosis, syphilis and others, in which the bone tissue is replaced by a specific granuloma.

However, there is no direct and direct destruction of the bone by a pathological tissue, but there is in fact atrophy from the pressure of the tissue of the bone itself (fibrous, cartilaginous, vascular).

In a number of cases, bone lesions of the osteoma of multiple exostoses suggest a hereditary cause, according to which 50% of patients already had relatives with a similar disease.

Symptoms and Diagnosis of Enostoses

This group includes osteophytes, i.e. layering on bones of small size. Osteoma is a fairly rare disease and in most cases overtakes men of young age.

The tumor looks like a smooth plate outside the bone, which is dense, immobile and painless.

Osteomas appearing on tubular bones grow slowly and differentiate as exophyte neoplasms.

Enostosis of the Thigh: Treatment and Features of the Disease

A widespread process leads to a diffuse thickening of the cortical layer, which in a number of cases becomes the cause of obliteration (infection) of the medullary canal.

A specific feature of osteoma is the presence around it of spines (spicules) of lamellar or fibrous bone substance.

Note: in the medical literature, the term "enostosis" may refer to focal osteosclerosis, which develops on the background of injuries, chronic intoxications and inflammatory processes.

Important: asymptomatic enostoses of unknown origin (for example, compact islands in spongy substance) are regarded as a specific condition of bone tissue, and not as a pathological process.

In most cases, the development of "bone islets" is not accompanied by any clinical manifestations. It is possible to detect such altered areas only during a radionuclide or radiological study.

Enostosis(enostosis, from the Greek. en-in, inside and osteon-bone) is a symptom of the pathological formation of bone substance from within the bone, from the side of the endosteum, under the influence of a variety of processes.

If the boundaries of the lesions in the femur are blurred, and the structure of the enostosis is not clear, there is reason to suspect osteogenic sarcoma. Enostosis is the increase in bone mass due to endoscopic sclerosis.

Enostosis develops often along with osteoporosis and periostosis.

Enostosis of the femoral and iliac bones, treatment

An enostosis is a benign neoplasm consisting of a lamellar bone tissue with a developed system of Havers channels.

The node is connected with the cortical layer, protrudes into the cerebral canal, can reach 20 mm in diameter, rarely grows up to 5 cm.

Condensation is individual, but the formation of multiple pathological sites is possible.

Enostosis of the femur often proceeds asymptomatically, it is diagnosed in cases of disturbances in the mineral metabolism, after mechanical trauma, against the background of oncological tumors and other ailments of the skeleton.

Features of pathology

Nodules are formed mainly in children and young patients under 35 years.Characteristic structural changes can occur in the spine, femoral, iliac and phalanges of the fingers.

A distinctive feature of the disease is the presence of spicules around the enostosis, which in appearance resemble thorns growing from the outer layer of bone tissue.

Pathological seals have a system of haversal canals through which nerve endings and small blood vessels pass.

Depending on which part of the bone is involved in the pathological process, distinguish:

1. spongy, cerebral or compact osteoma;
2. focal osteosclerosis.

Causes of development

The disease has a genetic predisposition: it is often found that close relatives of the patient suffered from such ailments.

Benign seals can form with prolonged intoxication of the body: when working on chemical production, contact with harmful substances, etc.

The main causes of thigh bone anemia:

• marble disease;
• violation of metabolic processes;
• syphilitic scales;
• increased load on lower limbs;
• osteogenic sarcoma;
• chronic osteomyelitis;
• tuberculosis of bones;
• hormonal imbalance;
• mechanical injuries;
• congenital malformations of the skeleton;
• chronic connective tissue diseases.

In most cases, the anesthetic is asymptomatic, determined by X-ray examination, CT. Rarely the formation of nodules in the femur causes the appearance of painful sensations, lameness.

The formation of islets is usually observed in the place of a fused fracture, with other bone diseases and may indicate a severe stage of pathology. Therefore, patients are advised to undergo a thorough examination.

Difficulties in diagnosing

To make the correct diagnosis, the doctor sends the patient to the x-ray of the hip area. This allows you to accurately determine the location of the enostosis, the shape and contour of the neoplasm, the presence of thorns, the degree of narrowing of the bone cavity.

Benign nodes should have distinct edges and a homogeneous structure.

With diffuse contours, there is a suspicion of osteogenic sarcoma, obstruction of the cerebral canal can be a sign of neglected osteomyelitis or marble disease.

The multi-focal nature of the pathology is diagnosed in osteopykology (spongy osteoma).

Enostosis is differentiated with oncological metastases, cancerous tumors, aseptic necrosis, sclerosing osteomyelitis, Brody's chronic abscess.

In addition, computed tomography, magnetic resonance therapy can be performed. Instrumental studies are also assigned to monitor the dynamics of therapy.

With unclear genesis and asymptomatic course, the disease is regarded as a feature of the anatomical structure, and not as a pathological process.

When making a diagnosis, the doctor takes into account the existing clinical symptoms and the results of the studies.

Methods of treatment of enostosis

If the pathology is small, does not cause a narrowing of the bone cavity, pain syndrome, a malfunction of the bone marrow, a specific treatment is not required. The patient should be registered with a doctor and periodically undergo a survey.

With large islands, rapid growth of tumors perform removal of the build-up. Enostosis is excised within healthy tissues to avoid the development of relapse. In the post-operation period, drug therapy is performed.

Single or multiple enostoses are formed with concomitant diseases of the skeleton, disruption of the mineral metabolism, after the inflammatory process and mechanical injuries of the femur.

The disease has no severe symptoms, it is most often found accidentally during an X-ray. If islets do not cause a person discomfort, do not break the normal functioning of the bone marrow, a specific treatment is not required.

Remove benign neoplasm only with obstruction of internal cavity of bones and large diameter.

Enostosis

The destruction of skeletal restructuring in dogs can be expressed in two different forms: cervical spondylopathy and an enostosis, osteoid osteoma.

Bone islet is a tumor-like nodule with a diameter of 2-20 mm (very rarely up to 4-5 cm), associated with cortical layer of bone Enostosis refers to random findings, because no clinical symptom is is followed.

Enostosis is the increase in bone mass due to endoscopic sclerosis. Enostosis.

Sarcoma, combined with bone marrow infarction.

Conclusion Enostosis of the wing of the ilium on the right. But it is almost always benign. Enostosis develops often along with osteoporosis and periostosis.

Osteoma, which is located above the surface of the bone, doctors called exostosis, and closed in a spongy substance - an enostosis.

Internal osteophytes (enostoses) grow into the medullary canal, usually are single (exclusion of osteopykilosis, inherited disease Registered: 22.03.2008 - 2: 5. osteon bone oozing bone marrow with bone tissue

About an enostose in a narrow sense, you can speak only in those cases. Also, often we diagnose pain of growth (an enostosis) in short-horned dogs, such as the English and French bulldogs, and also often meet the enostosis of the German Shepherds.

Enostoses or osteomas are benign tumorous neoplasms in the form of nodules. Medspravka: Ear washing is a procedure used to remove from the external auditory canal.

See what is the "enostosis" in other dictionaries: Enostosis - (enostosis en greek.ostny island) - a tumor-like nodule with a diameter of 2-20 mm (very rarely up to 4-5 cm), associated with the cortical layer of bone Enostosis, also known as the bone islet, this benign bone lesion is usually a random find.

(Enostosis en-greech. His tissue gradually passes into the surrounding bone When they occupy a vast area they are called hyperostosis. Osteoid osteoma.

His tissue gradually passes into the surrounding bone. The Enostoz (his so-called bone marrow) is a tumor-like, benign formation, in an otherwise peculiar nodule like the enostosis. Diagnosis of an enostosis is possible only on the basis of an X-ray study.

Their dimensions are in most cases relatively small from 2 to 20 mm.

"Growth pain or an enostosis, have many symptoms, many of which are similar to serious diseases, such as elbow or hip dysplasia, or many more other diseases that the Enostosis is in one line of diseases such as osteoma, which means that it is classified as benign bony tumors and tumor-like formations.

Osteoma of the tibia

Enostosis(sin.ostny island) - a tumor-like nodule with a diameter of 2-20 mm (very rarely up to 4-5 cm), associated with the cortical layer bones, protruding into the medullary canal and folding from the lamellar bone tissue with a well-developed system of Havers channels. Typically, this is a single neoplasm that appears in any bone. Only with autosomal dominant disease - osteopoxylosis (spotted bone) - the neoplasm is not uncommon plural.

Enostosisrefers to random findings, because there is no clinical symptomatology. Its tissue slowly passes into the surrounding bone, and the boundary between them is not determined.

Another distinguishing feature is the presence near the enostosis of small bony spines - spicules resembling the brush border and growing from the cortical layer of bone.

These spinules are composed of lamellar or fibrous bone, and sometimes from a combination of the two.

Osteoma

OsteomaIs a tumor-like node of a very dense bone, with a microscopic examination revealing all the indicators of ordinary bone tissue.

Favorite localization - bones of the skull (in men 2 times more often than in women) and facial bones (3 times more often in ladies). Some osteomas sprout into the skull cavity and can squeeze the nerve trunks.

The presence of osteoma in one of the paranasal sinuses is in most cases accompanied by symptoms of airway obstruction.

In the presence of multiple osteoma or involving in the process of long tubular bones, it comes mostly about Gardner's syndrome.

In most cases, tumor-likeproliferation of bone tissueon the outer surface of one or another tubular bone (so-called parostal osteoma), which, during X-ray examination, can take the form of uneven wavy thickenings cortical layer. Under the microscope, two types of osteoma are distinguished. The first type, seen most often, consists of a very dense compact bone, the other is a lamellar bone, in cells of which there is a fibrous-fat tissue or a hematopoietic bone marrow, it is called spongy, trabecular or mixed osteoma.

With differentialdiagnostics. In addition to reactive growth of bone tissue, osteoma is directed to distinguish from being guided by fibrous dysplasia and solid odontoma.

In long tubular bones, osteoma should be differentiated from organized periosteal calluses and osteochondrosis with ebournection of cartilaginous capsules.

Osteoma is difficult to distinguish from reactive growths of bone tissue after the end of infection, injury, and dilapidated osteochondrial with atrophied cartilaginous margins.

Osteoid osteoma

Osteoid osteoma(syn. osteoid-osteoma) - benign, in most cases, a single neoplasm, not exceeding I cm in diameter, having clear contours and located in any bone of the skeleton, not counting the bones of the skull and sternum.

The frequency of osteoid-osteoma is 2-3% of the total number of bone tumors and 12% of the total number of benign bone tumors. Most patients - people under 25 years and younger, and men are sick twice as often as women.

The usual localization of osteoid osteoma-bone of the lower limbs, their diaphysis and metaphysis. Approximately a good half of the tumors are found in the proximal metaphysis of the femur and in the tibia.

This tumor in most cases begins in the cortical layer of the bone, despite the fact that other localization, for example subperiosteal area and bone marrow can not be ruled out.

Characteristic for this tumorthere is a gradual increase in soreness in the area of ​​the lesion.

In most cases, the pain appears then, at a time when the radiographic indices of tumor growth are not yet determined. Soft tissue over the affected bone is edematous and painful.

With the growth of the tumor in the epiphysis, there is often an effusion in the corresponding joint, This gives an excuse for erroneous diagnosis of arthritis, especially in those cases in which the time when a syncope in the biopsy of the synovial membrane reveals the villous growth of the synovial membrane, which is common for a chronic secondary synovitis.

Osteoid osteoma. located near the germinal epiphyseal area, induces the growth of the affected bone, which leads to the formation of asymmetry of the skeleton.

Iftumor nodelocalized in the vertebra, in patients there is a painful scoliosis or symptoms of compression of the peripheral nerves.

Proceeding from this, the treatment of scoliosis in adults requires special attention, so as not to exclude this pathology and not treat complications of the main process.

Only at the end of the healing process can be advised to treat the scoliosis of the spine.

In radiologic studies, osteoid-osteoma is detected as a subcortical site ossification surrounded by a rim of osteosclerosis, the width of which increases with progression tumor.

Along with this, the central part of the tumor becomes less noticeable. The boundary between the central sclerotic rim and the bright zone, distinct in the early period, is erased over time because the central area of ​​the tumor is subjected to ossification and calcification, which are spreading centrifugal.

Growth of cortical and subperiostealosteoid-osteomeis accompanied besides this by a reactive sclerosis. There are indications and that if the neoplasm grows in the medullary canal, then the corresponding bone begins osteoporosis.

In most casestumorIt is easily extracted from the surrounding bone and macroscopically represents a fine-grained, reddish-brown bone tissue.

If it does, then a decade or later after the removal of the primary node of the tumor.

Under the microscopeborder of osteoid osteomais well defined against the background of the surrounding sclerotized bone tissue with a huge number of vessels.

The central (osteoid) part of the tumor consists of fancifully interwoven cords and trabeculae of the osteoid surrounded by osteoblast clusters and a loose, vasculature-rich fibrous stroma.

Osteoblasts in the tumor tissue are large, as if swollen, with rounded huge nuclei. Mitosis figures are often seen. In the osteoid part of the tumor, the osteoblasts are in the form of a rim of the maligning of the forming bone beams.

Hematopoietic cells and adipose tissue inclusions in osteoid-osteoma are not determined. The non-specialized appearance of the osteoid resembles an intricate ligature.

In some placestumorsosteoclasts are seen - single or forming small groups.

In younger tumors, the osteoid forms the predominant part of the neoplasm, but as the tumor grows older, areas of calcification, and in mature tumors, on a par with osteoid, a real fibrous bone is formed, formed from compact trabeculae.

In those cases, at a time when a fracture appears at the location of the osteoid-osteoma, it is possible to encounter a cartilaginous tissue among the osteoid. The latter is found in tumors growing under articular cartilage. By and large, metaplasia of osteoid tissue in the cartilaginous for osteoid-osteoma is not typical.

This is the structure of the osteoid-osteoma in the center. Near it, in the form of a strip 1-2 mm wide, there is a fibrous tissue, rich in blood vessels, in which the trabecular The pattern is no longer determined. A layer of the sclerotized cortical plate is found further to the outside. In rare cases, it is absent.

Osteoid osteomadifferentiate from intracortical abscess, osteosarcoma, sclerosing osteomyelitis, enostosis, aseptic necrosis, eosinophilic granuloma and metastases of malignant tumors.
