chondromyxoid fibroma
Introduction
Introduction to cartilage myxoid fibroma Chondromyxoid fibroma (chondromyxoid fibroma) is a rare benign bone tumor that originates from cartilage-like connective tissue. Jaffe named it "chondral mucin-like fibroma", mainly based on its histological features. Histological manifestations include both cartilage-like tissue and some megakaryo or atypical cells in the mucin-like matrix, which have been misdiagnosed as chondrosarcoma in the past. basic knowledge The proportion of illness: 0.02% Susceptible people: no special people Mode of infection: non-infectious Complications: fracture
Cause
Cause of cartilage myxoid fibroma
Cause (50%):
It is a special differentiated cartilage-derived benign tumor. There is often a clear boundary between the cartilage myxoid fibroma and the host bone. The medullary cavity has a scalloped or nodular-like hardened margin. The typical cartilage-like fibroids are eccentrically grown in the bone, but the total tumor is The orientation is parallel to the long axis of the long tubular bone. The cartilage myxoid fibroma is located in the center of the short bone and the tibia. The surface of the cartilage is blue-gray to blue-white, similar to the color of hyaline cartilage and fibrocartilage. The majority of the small cyst or mucus area can be seen in the section of the tumor, and the hardness of the contents of the tumor can be solid, soft or rubbery.
Prevention
Chondromyxoid fibroma prevention
Strengthen physical exercise, enhance physical fitness, and exercise more in the sun. Excessive sweating can excrete acidic substances in the body with sweat, avoiding the formation of acidic body. Have a good attitude to cope with stress, work and rest, do not fatigue.
Complication
Complications of cartilage myxoid fibroma Complications
Pathological fractures can sometimes be combined.
Symptom
Symptoms of cartilage myxoid fibroma Common symptoms Soft tissue swelling Spontaneous fracture of knee pain
There are no special clinical symptoms, mainly chronic progressive pain in the lesions. Local examination may have tenderness and swelling, limited limb activity, etc. The time of clinical symptoms varies from treatment to treatment. The early ones can only be one week. For several years, children with cartilage myxoid fibroma, characterized by rapid development of clinical symptoms, although spontaneous fractures are rare, but if it occurs, it is often the cause of the patient's attention, and the cartilage-like fibroids are completely symptom-free. It is also rare.
Examine
Examination of cartilage myxoid fibroma
Cartilage myxoid fibroma usually presents as a benign tumor on X-ray films, and there may be some differences depending on where the tumor is located. When the tumor is located in the long tubular bone, the cartilage myxoid fibroma is usually at the metaphysis, and the eccentric radiation changes. The size of the tumor can range from 2 to 10 cm, and the bones are thickened. The cortical bone of the lesion area expands, the periosteum hardens, and the trabecular bone becomes thicker. There is generally no periosteal reaction and pathological fractures, and calcification in the lesion area is rare.
Diagnosis
Diagnosis and identification of cartilage myxoid fibroma
According to the medical history, clinical manifestations, the incidence of young adults and the typical X-ray findings, most of them can be diagnosed.
For the differential diagnosis of cartilage myxoid fibroma, it should be carried out from clinical, X-ray findings and pathological structure, and should be identified with the following benign bone tumors:
1. Non-ossifying fibroma: located in the backbone, eccentricity, obvious peripheral sclerosis, and less expansion of cortical bone.
2. Benign chondroblastoma: occurs in adolescents, located in the epiphysis, is eccentric, low transmittance, visible calcification in the lesion, no hardened edge.
3. Giant cell tumor of bone: It occurs in the age of 20 to 40 years old. It is located at the end of the long bone, mostly in the epiphysis, lateral expansion, obvious expansion of the cortex, and often no hardening around.
4. Bone cysts: occur in children and adolescents, the lesions are mostly located at the metaphysis, and develop with the growth of the backbone with age, expansive growth, high transparency, and clear hardening edges.
