Cherry hemangioma

Introduction to cherry hemangioma Cherry angioma (cherryangiomas), also known as senile angiomas (senileangiomas), is the most common hemangioma, which begins to appear in early adulthood and increases with age, mainly in the trunk, rare in the hands, feet or face. . basic knowledge The proportion of illness: 0.002% Susceptible people: seen in the elderly Mode of infection: non-infectious Complications: dyskinesia

The cause of cherry hemangioma

(1) Causes of the disease

At present, most scholars believe that during the development of human embryos, especially in the early stage of vascular differentiation, due to the small-scale misconfiguration of the control gene segments, the tissue differentiation of specific parts is abnormal and develops into hemangioma. Some scholars believe that in the early embryonic period (8 ~ 12 months), embryonic tissue suffers mechanical damage, and local tissue hemorrhage causes some hematopoietic stem cells to be distributed to other embryonic characteristic cells, some of which differentiate into vascular-like tissues and eventually form hemangioma.

(two) pathogenesis

Hemangiomas are made up of a large number of proliferating blood vessels. In the early stages of the embryo, the primitive vasculature is a tube of purely endothelial cells that form a dense network in the middle of the interstitium. Later, as each organ develops, the original vascular network gradually differentiates into many vascular plexuses and lymphatic plexus associated with the organ.

During the embryonic development of blood vessels, there are three stages: plexus stage, reticular stage and tube dry stage. If a disorder or abnormality occurs during the normal development of a certain stage, a deformity of the normal developmental morphology at this stage may occur. In the plexiform stage, if some capillaries stop developing, capillary hemangioma will occur; in the reticular stage, if the enlarged blood vessels gather into a mass and tend to fuse together, a cavernous hemangioma can be expressed.

Cherry hemangioma prevention Strengthen exercise, enhance physical fitness, and improve immunity. Regular participation in physical exercise, such as health gymnastics, practicing Qigong, Tai Chi, doing radio gymnastics, walking, etc., is of great benefit. Anyone who insists on physical exercise will have a strong body and strong disease resistance, and rarely suffer from illness.

Cherry hemangioma complications Complications

The complications of cherry hemangioma are ulcers, hemorrhage, infection, vital organ dysfunction, congestive heart failure and limb deformity caused by musculoskeletal damage. If the cherry hemangioma invades the cervical vertebra, symptoms of nerve root compression, such as pain, upper limb sensation and movement disorder, may occur.

Symptoms of cherry hemangioma Common symptoms Skin hemorrhagic plaque developmental malformation

It is oval or round, with a diameter of 0.5-0.6mm deep red papules. It is soft, higher than the leather surface, hemispherical, and the number varies. It can begin to appear in early adulthood and increase with age. Older people appear more or less, damage can occur throughout the skin, but mainly in the trunk, rare in the hands, feet or face.

Examination of cherry hemangioma

Histopathology: It can be seen that many moderately dilated capillaries line the flattened endothelial cells, and the epidermal cells become thinner and often surround the majority of the hemangioma, just like a small collar.

Diagnosis and identification of cherry hemangioma

diagnosis

It is oval or round, with a diameter of 0.5-0.6mm deep red papules. It is soft and taller than the leather surface. It is hemispherical. The number varies, and can begin to appear in early adulthood, increasing with age, and perhaps 70-year-olds may appear more or less. Damage can occur throughout the skin, but mainly in the trunk, rare in the hands, feet or face. According to the clinical manifestations, the characteristics of skin lesions, histopathology, can make a diagnosis.

Differential diagnosis

The disease should be differentiated from glomus tumors, angiosarcomas, etc., and its characteristics are as follows:

1. A glomus tumor, a sharp painful mass in the toenail bed and its vicinity. The pain is especially painful during cold stimulation. Located under the armor, visible fingernails, local toe of the toenail, the surface can be light red, purple or slightly dark, more than touch.

2. Angiosarcoma is rare, the tumor is nodular, painless, purple-red, superficially easy to bleed and ulceration. Under the microscope, many disordered tumor blood vessels are seen. The tumor cells proliferate in the basement membrane and can be attached to the inner wall of the blood vessel to form a nodular protrusion in the lumen. The tumor cells are mostly fusiform, and the undifferentiated ones are polygonal, endothelium-like, with large nuclei, deep staining, and more nuclear division. Polynuclear giant cells can be seen.
