Hemangioma on the top of the head

Hemangioma refers to a tumor inside the human body's blood vessels. In terms of symptoms, many purple or dark spots or patches will appear on the patient's skin, which will be painful if pressed with the hands. Some people find that they have hemangiomas on the top of their heads after examination. If not treated in time, the hemangiomas on the top of the head may even compress the nerves. So, what should you do if you have a hemangioma on your head?

1. Is it serious if a hemangioma grows on the top of the head?

The cause of hemangioma may be capillary, and it is related to congenital developmental malformations. The treatment of this disease is currently mainly surgical resection or local injection of drugs. Physical therapy can also be used.

2. Clinical manifestations of hemangioma

1. Capillary hemangioma

Tumors are composed of large numbers of intertwined, dilated capillaries. It appears as bright red or purple patches. It is flush with the skin surface or slightly raised, with clear boundaries, irregular shapes and varying sizes. When the tumor is pressed with the fingers, the color fades; when the pressure is released, the color returns.

2. Cavernous hemangioma tumors are composed of enlarged vascular lumens and blood sinusoids lined with endothelial cells. The lesions are purple, dark red or bluish-red nodules or plaques of varying sizes. They are soft in texture, and the blood sinuses are of different sizes, like a sponge-like structure. The sinus cavities are filled with venous blood and communicate with each other. The surface is hemispherical or lobed, and its volume can be reduced by compression. Mostly single shot. Histopathology showed that the blood vessels in the lower dermis and subcutaneous tissue were enlarged into irregular cavities filled with blood. Hyperplasia of vascular adventitial cells. It presents as an asymptomatic, slow-growing soft mass. When the head is in a low position, the tumor expands due to congestion; when the body returns to normal position, the mass returns to its original shape. Superficial tumors have a bluish-purple appearance on the skin or mucous membrane. For deeper ones, the skin color is normal. The mass was soft, with unclear borders and no tenderness when palpated. The lump shrinks when squeezed and returns to its original size when the pressure is released.

3. Racemose hemangioma

It is mainly formed by the anastomosis of dilated arteries and veins. The tumor is elevated and has a bead-like or earthworm-like shape. There is a pulsation and thrill on palpation, and a blowing murmur on auscultation. If all the blood supplying arteries are compressed and blocked, the above-mentioned pulsation and murmur will disappear.
