Periosteal chondroma
Introduction
Introduction to periosteal chondroma Periosteal chondroma is a type of chondroma that occurs on the surface of the bone, subperiosteal, tendon and ligament attachment. It is located in the diaphysis or metaphysis of the long bone and occurs at the proximal end of the humerus. It can occur in all age groups from children to adults. The clinical manifestations are a slow progression with a swollen mass with or without pain. If surgery is required, all tumors should be removed. X-ray examination showed a dish-shaped depression on the cortex, which is quite superficial, even with a slight multi-ring, marked with a bone-hardening line, generally not extending to the medullary cavity. The lens-like or hemispherical chondroma mass has a similar soft tissue. X-ray linear, even with X-ray opaque particles and shadows, indicating cartilage calcification and / or ossification, along the periphery of the chondroma, the periosteum up from the cortical bone can produce bone spurs, surrounding the base of the tumor . basic knowledge The proportion of illness: 0.005% Susceptible people: no specific population Mode of infection: non-infectious Complications: periostitis
Cause
Cause of periosteal chondromatosis
Cause:
Periosteal chondroma is a benign chondroma derived from the periosteum or subperiosteal connective tissue. The tumor seen by the naked eye consists of encapsulated leaflets of dense hyaline cartilage. Compared with central chondroma, the cells are richer and larger than the central chondroma; the nucleus occasionally has different sizes, the nuclear is full, the mild pleomorphism, and some binuclear cells, these are "normal". It has a different prognostic significance from the same tissue image that appears in central cartilage tumors of long bones or torso bone.
Pathogenesis:
The X-ray of the tissue is linear, and may even contain X-ray opaque particles and shadows, indicating calcification and/or ossification of the cartilage. Along the periphery of the chondroma, the periosteum that is lifted from the cortical bone can produce bone spurs that surround the base of the tumor.
Prevention
Periosteal chondroma prevention
Pay attention to rest, work and rest, life in an orderly manner, and maintain an optimistic, positive, and upward attitude towards life. It is very helpful to prevent diseases, pay attention to daily diet:
First, limit the intake of pickled, smoked, and nitrite-containing foods.
Second, maintain the ideal weight.
Third, intake of a variety of food.
Fourth, the daily diet includes a variety of vegetables and fruits.
5. Ingest more high-fiber foods (such as whole grain cereals, beans, vegetables, and fruits).
6. Reduce total fat intake.
7. Limit the intake of alcoholic beverages.
Complication
Periosteal chondroma complications Complications periostitis
Compression of nerves, blood vessels, late dysfunction, lymphatic vessels, and hematogenous metastasis.
Symptom
Periosteal chondroma symptoms common symptoms long bone swelling pain bone pain myalgia
It can be seen that moderate swelling is slow, sometimes quite large, with little swelling, with or without pain.
Examine
Examination of periosteal chondroma
X-ray examination showed a dish-shaped depression on the cortex, which is quite superficial, even with a slight multi-ring, marked with a bone-hardening line, generally not extending to the medullary cavity. The lens-like or hemispherical chondroma mass has a similar soft tissue. X-ray linear, even with X-ray opaque particles and shadows, indicating cartilage calcification and / or ossification, along the periphery of the chondroma, the periosteum up from the cortical bone can produce bone spurs, surrounding the base of the tumor .
Diagnosis
Diagnosis and diagnosis of periosteal chondroma
Diagnosis must be differentiated from periosteal chondrosarcoma.
