Capillary hemangioma symptom?

summary

Capillary hemangioma is a kind of congenital benign tumor or vascular malformation, which is more common in infants at birth or shortly after birth. It originates from residual embryonic vascular cells. Active endothelial like germ invades into adjacent tissues to form endothelial like cords. After being managed, it is connected with the left blood vessels to form hemangioma. The blood vessels in the tumor form their own system and are not connected with the surrounding blood vessels. Hemangiomas in oral and maxillofacial region account for 60% of the total hemangiomas. Most of them occur in facial skin, subcutaneous tissue and oral mucosa, such as tongue, lip, floor of mouth, and a few occur in jaw or deep tissue.

Capillary hemangioma symptom?

Tumor is composed of a large number of interwoven and dilated capillaries. The plaque was bright red or purplish red. It is flush or slightly raised with the skin surface, with clear boundary, irregular shape and different size. When the tumor was pressed by fingers, the color of the tumor faded; After the pressure is released, the color is restored.

The tumor consists of an enlarged vascular cavity and a blood sinus lined with endothelial cells. The blood sinuses are of different sizes and have sponge like structures. The sinuses are filled with venous blood and communicate with each other. It was a soft mass with no symptoms and slow growth. When the head is low, the tumor is enlarged due to hyperemia. After the body position is restored to normal, the mass will return to its original state. The superficial tumor, the surface of the skin or mucosa was purple. The skin color was normal in the deep part. When palpated, the mass was soft, with unclear boundary and no tenderness. The mass shrinks during compression and returns to its original size when the pressure is released.

It is mainly composed of dilated arteries and veins. The tumor was like a rosary or earthworm. The palpation has the feeling of palpitation and tremor, and the auscultation has the whistling murmur. If all the feeding arteries were closed, the above pulsation and murmur disappeared.

matters needing attention

No specific findings were found in general laboratory examination. For the patients with superficial and limited tumors, the examination frame "a" was the main examination item; For the patients with deep lesions or huge tumors, the examination items can include "B" and "a". X-ray examination of the neck is valuable to understand the size and extent of the deep tumor or whether the tumor invades the cervical or laryngeal cartilage. If preoperative angiography can find out the nutrient branches of hemangioma, ligation of supply vessels at both ends of hemangioma can reduce intraoperative bleeding, which is conducive to complete resection of hemangioma.
