Dormant lipoma

Introduction to sputum lipoma Hibernoma (brownfattumor) is a benign tumor composed of brown fat cells. Brown fat is present in mammalian and human fetal stages and gradually decreases with age. basic knowledge The proportion of illness: 0.001% Susceptible people: no specific population Mode of infection: non-infectious Complications: malignant melanoma

The cause of sputum

the reason

The cause is still unknown.

Pathogenesis

The pathogenesis is still unclear.

Locust lipoma prevention

The etiology of this disease is not clear, and may have certain correlation with environmental factors, genetic factors, dietary factors, and mood and nutrition during pregnancy. Therefore, it is impossible to directly prevent the disease against the cause. Early detection, early diagnosis and early treatment are of great significance for indirect prevention of this disease. At the same time, complications such as organ compression can be reduced. For large tumors, surgical resection should be performed as soon as possible to avoid suffocation caused by compression of the trachea.

Obstructive lipoma Complications malignant melanoma

Tumors occur in the scapular region, chest, neck, etc., often under the skin, occasionally reach muscle tissue, the boundary is clear, the diameter can reach 19cm (average 10cm), benign slowly increase, occasionally tender. Histopathology: Some large mature fat cells can be seen. No significant complications have been found so far.

Symptoms of sputum lipomas Common symptoms Slow growth Skin tenderness Cystic mass

Tumors occur in the scapular region, chest, neck, femoral, etc., often under the skin, occasionally reach muscle tissue, the boundary is clear, the diameter can reach 19cm (average 10cm), clinically benign, slowly increase, occasionally tender.

Examination of sputum lipoma

Histopathology: The tumor tissue has a complete envelope, which is divided into numerous small leaves by the connective tissue. The tumor cells are large brown fat cells with a diameter of 20-50 m, polygonal, rich in cytoplasm, containing a large number of eosin particles, more vacuoles. Positive for fat staining, proved to have lipids, lipofuscin is seen between the cytoplasmic foam, the nucleus is small and round, centered or biased to one side, and the blood vessels in the tumor are abundant, and some mature mature fat cells are scattered.

Diagnosis and identification of sputum

According to the clinical manifestations, the characteristics of skin lesions and histopathological features can be diagnosed.

1. Xanthoma cells are small in size and often accompanied by other inflammatory cells and proliferating fibroblasts. Xanthophynal giant cells are characteristic.

2. Granulous myoblastoma has no complete capsule, and the tumor cells are arranged in a nest or bundle.
