What are soft tissue nodules? The following four points will help you understand

Soft tissue nodules are nodules that originate from mesenchymal tissue and are located within the soft tissue. Mainly soft tissue nodules of the musculoskeletal system. Soft tissue tumors can occur in any part of the body at any age, but are more common in young and middle-aged people, and most often occur on the trunk. What are soft tissue nodules?

1. Congenital malformations

Hemangiomas are more common in infants and children. The manifestations of vascular malformations are abnormal dilation of capillaries, venules, arterioles and lymphatic vessels, without endothelial cell proliferation and low mast cell counts. They can be divided into venous type, capillary type, lymphangioma type and arteriovenous fistula type. Most of these lesions are discovered after birth.

2. Familial inheritance

Years of research have observed that many tumor cells display chromosomal abnormalities. People with chromosomal abnormalities have a higher incidence of tumors than normal people, and there is a familial hereditary phenomenon. These situations all support that the occurrence of tumors is closely related to family heredity. We have also further recognized the phenomenon of autosomal dominant inheritance, but its penetrance is not consistent.

3. Foreign body stimulation

Animal experiments and clinical observations have shown that long-term physical stimulation of the body by foreign objects can induce soft tissue tumors.

4. Chemical stimulation

It has been confirmed that polycyclic hydrocarbons have an inducing effect, but there is still a lack of strong evidence for humans. Only epidemiological surveys have found that a small number of workers who have long-term exposure to polyvinyl chloride will develop hepatic angiosarcoma.
