Baby's head with red envelope

If a red bump suddenly appears on your baby's head, the first thing to do is to observe whether it is a mosquito bite, and secondly to observe whether it is skin eczema or other problems. If parents really can't judge, they should observe whether the red bump has the possibility of spreading or growing. If there is any abnormality, go to the hospital for examination and let the doctor give the answer. Many parents are particularly afraid that their babies have vascular nevus. This disease is not that scary and there is no need to worry.

Vascular nevus is the most common benign tumor in infants and is formed by the proliferation of vascular network during the embryonic period. There are two types of vascular nevi: hemangiomas and vascular malformations. Vascular malformations are vascular malformations that may persist throughout life. Hemangioma is caused by the proliferation of vascular endothelial cells. Strawberry hemangioma and cavernous hemangioma are more common clinically. Hemangiomas should be treated actively, and laser therapy, hormone therapy, radiotherapy, cryosurgery and surgery can be selected as appropriate.

Causes and common diseases

Vascular nevus is formed by the proliferation of vascular network during the embryonic period.

There are two types of vascular nevi: hemangiomas and vascular malformations. Vascular malformations are vascular malformations that may persist throughout life. Hemangioma is caused by the proliferation of vascular endothelial cells. Strawberry hemangioma and cavernous hemangioma are more common clinically.

Differential Diagnosis

Hemangiomas need to be differentiated from hemorrhagic nodules. The former have a typical appearance and the characteristic of disappearing or becoming lighter in color when pressed with fingers. If necessary, the hemangioma can be aspirated with a needle to draw out fresh blood; the blood drawn from the bleeding nodule is old blood, which may be mixed with other components.

examine

General laboratory test results showed no specific findings. X-rays are valuable in understanding the size and extent of deep tumors or whether the tumors erode the cervical spine or laryngeal cartilage. Deeper hemangiomas should be confirmed by postural movement tests and puncture. Arteriography and aneurysm cavity angiography can also be used to assist in diagnosis.

Treatment principles

The treatment of hemangioma should generally establish the concept of active treatment. On the basis of correct diagnosis, the following methods can be selected according to the specific situation:

1. Laser treatment. In recent years, the use of laser to treat superficial vascular diseases has become more popular.

2. Hormone therapy, local hormone injection therapy and oral corticosteroid therapy.

3. Radiation therapy is generally not recommended for children.

4. Freeze.

5. Surgical treatment.

6. Follow-up observation is the first choice for hemangiomas that are not growing very obviously or have entered the stable or regressing stage.
