Mixed hemangioma

Introduction to mixed hemangioma Mixed hemangiomas are other types of hemangiomas such as capillary hemangioma, cavernous hemangioma, and two or more benign hemangioma. It is a common type of hemangioma, which occurs mostly in the face and neck and can also occur in other parts of the body. It usually exists at birth and initially resembles a strawberry-like capillary hemangioma, but it quickly spreads beyond the skin and penetrates deep into the dermis and subcutaneous tissue. At the beginning, most of the small erythema with different skin surface size is not the same as the simple strawberry hemangioma. However, with the development of surface hemangioma and simultaneous invasion of the dermis and subcutaneous tissue, the subcutaneous invasion can exceed the surface lesion. The area, which forms a raised mass, is irregular in shape and is more common in the face and limbs. The scope of the violation is sometimes so wide that tissues, organs such as the eyes, lips, nose or ears are covered by this expanding vascular tissue, causing dysfunctions such as breathing, diet, vision and hearing. basic knowledge The proportion of illness: 0.001% Susceptible people: no specific population Mode of infection: non-infectious Complications: keloids

Mixed hemangioma etiology

1. It is very important in human embryonic development, but in the early stage, vascular tissue abnormalities will develop into hemangioma, which is a very serious consequence. Medicine pointed out that this is related to congenital factors. Some babies have this disease at birth and appear to be triggered during embryonic development.

2. During the development of human embryos, in the early stage (8-December), if the sin is mechanically damaged, local tissue may also cause bleeding, and some of the vascular tissue will develop lesions, eventually forming hemangioma. The development of hemangioma is very fast, and it will be spread over half of the body in a few weeks.

Mixed hemangioma prevention

Patients with mixed hemangioma and their families should pay attention to the disease site, be careful not to scratch, keep dry, pay attention to clean to prevent infection. The diet should be light, and it is not advisable to use too spicy food to avoid ulceration.

Mixed hemangioma complications Complications keloid

1. Mixed hemangioma grows rapidly and is extremely aggressive. Within a few weeks, normal tissues can be severely damaged, so that tissues such as eyelids, lips, nose and ears are covered by expanding hemangioma tissue.

2, the shape of the tumor is irregular, purple-red, prone to ulceration, bleeding, infection, necrosis, scar formation.

3, mixed hemangioma enlargement can also cause a series of secondary problems, eyes, ears are covered, lips swelling, etc., resulting in respiratory, diet, vision, hearing and other dysfunction.

4, mixed hemangioma grows rapidly after the birth of the baby, and continues to grow and expand, to the surrounding skin and deep tissue invasion, severely cause hemangioma small plate to reduce the syndrome, life-threatening.

Symptoms of mixed hemangioma Common symptoms Erythema (Boundary clear skin necrosis Spotted hemorrhagic hypertrophic scar Respiratory abnormalities Hearing impairment Visual field of vision changes

At the beginning, most of the small erythema with different skin surface size is not the same as the simple strawberry hemangioma. However, with the development of surface hemangioma and simultaneous invasion of the dermis and subcutaneous tissue, the subcutaneous invasion can exceed the surface lesion. The area, which forms a raised mass, is irregular in shape and is more common in the face and limbs. The scope of the violation is sometimes so wide that tissues, organs such as the eyes, lips, nose or ears are covered by this expanding vascular tissue, causing dysfunctions such as breathing, diet, vision and hearing.

Hybrid hemangioma

1. Histopathological examination.

2. Angiography shows contrast agent concentration or vascular malformation.

3. Positive position test, percussion and venous stone, puncture and extraction of whole blood (sponge type).

4. Palpation: Fading or shrinking.

Diagnosis and diagnosis of mixed hemangioma

diagnosis method:

Histopathological examination confirmed the diagnosis.

The appearance of the tumor (wine spotted or strawberry).

Angiography shows contrast agent concentration or vascular malformation.

The body position test was positive, percussion and venous stone, puncture and extraction of whole blood (sponge type).

Fading or shrinking.

Differential diagnosis

Different from glomus tumors and angiosarcomas, the 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.

Immunohistochemistry is important for the diagnosis and differential diagnosis. Sensitive endothelial markers, VIII-related antigens, CD31, CD34, etc. can be selected to help determine the diagnosis.
