Can mosquito bites cause hemangiomas?

**Unclear, but studies suggest that progesterone or chorionic puncture during pregnancy, gestational hypertension, and low birth weight may be associated with the development of hemangiomas. It is believed that hemangioma is a small area of tissue differentiation in the control gene segment during the development of human embryos, especially in the early stage of vascular tissue differentiation, resulting in abnormal tissue differentiation in specific parts and developing into hemangioma. In the early embryonic period (8 to 12 months), the embryonic tissue suffers mechanical damage, and local tissue hemorrhage causes some hematopoietic stem cells to be distributed into other embryonal cells, and some of them differentiate into angioids, and eventually form hemangiomas.

Hello! The cause of hemangioma is not very clear, and there are roughly the following factors: genetic factors; Environmental factors; drug factors; Traumatic factors, etc., the above factors lead to abnormal expansion and hyperplasia of the vascular network within 3 months of the embryo, and the specific causes of hemangioma are being jointly developed by our hospital and the Institute of Molecular Research of Peking University.

Your description of the child may be a strawberry hemangioma of capillary hemangioma, at present, the hemangioma in infants and young children is recommended to be mediated by minimally invasive**, that is, under the high-frequency color ultrasound positioning, the catheter nanoneedle is used to directly act with the tumor to make the tumor slowly organize, shrink and disappear, and there is no pain or trauma after the absence of scarring.

There is no need for surgery, and it is easy to remove the unclean one.

It is recommended that you can pay for a child's affected part of the ** to help you with a better answer.

Mosquito bites will not cause hemangiomas, infantile hemangiomas are mostly congenital, and it is recommended to observe and make a clear diagnosis.

In terms of appearance alone, the bag bitten by a mosquito does look like a hemangioma, which is red and red, and it is higher than the surface of the **, and it will fade after pressing.

However, in essence, the two are completely different, one is a congenital vascular malformation or benign tumor, and the other is temporary redness and swelling. The causes and components are completely different.

There are three most common types of hemangiomas: strawberry hemangiomas, cavernous hemangiomas, and bright red nevi. Strawberry-shaped hemangioma is often located on the surface of the first place, rising from the skin surface, some are hemispherical, red, and the surface is strawberry-like appearance.

The cavernous hemangioma is relatively deep and looks purple or purplish-red on the surface, but the softer bottom can be reached with your hands.

Early symptoms of hemangioma:

One is the abnormal change of color: red, dark red, blue, purple, purple red in a certain part of the body may be the manifestation of hemangioma, some hemangiomas such as bright red nevus, when born, you can find the abnormal appearance of red on the surface, and cavernous hemangioma, cranoid hemangioma, etc. may not have abnormal color on the surface, and it may also appear blue and purple from the subcutaneous, and a large part of them are treated as "birthmarks" by the people and ignored.

The second is a lump or protrusion. A typical feature of hemangioma is that there is a mass on the surface or subcutaneous protrusion, such as a strawberry hemangioma with a red protrusion around the normal**, and a cavernous hemangioma will have a soft mass under the skin, and some of them may be mistaken for trauma.

The third is the local temperature, and the local temperature of some hemangiomas is higher than the surrounding normal.

Fourth, the abnormal pulse of the blood vessels, and the obvious arterial pulse can be felt locally in the arterial malformation.

Hemangiomas are low-blood vascular malformations that appear at birth, also known as venous malformations. Vascular damage generally develops slowly, often enlarges during childhood or adolescence, most venous malformations are spongy, and lesions can occur under the mucosa, muscles and even bones in addition to ** and subcutaneous tissues. Cavernous hemangioma can occur in any part of the human body, including internal organs, with the characteristics of dilated and infiltrative growth, which can be disfiguring and can cause organ dysfunction.

Hello! The surface color of hemangioma is mostly dark red, light red, blue purple, colorless, dark red and black, and the surface color of different types of hemangiomas is also different, such as bright red nevus (red birthmark) is mainly dark red or light red, bright red nevus belongs to the category of microvenous malformations, cavernous hemangioma is also divided into superficial and deep, the superficial type is mainly blue and purple, and the surface color of the deep type is normal.
