What are the clinical manifestations of hemangioma?

Capillary hemangioma is composed of abnormally developed and dilated capillaries. It is mostly found in the face and oral mucosa and is bright red or purplish-red if it is not higher than the skin, with clear perimeter and irregular shape, in the shape of wine spots; if it is higher than the skin, the surface is uneven and resembles prune-like when the tumor is pressed because blood flows out of the tumor and the surface color recedes. Cavernous hemangioma is composed of numerous blood sinuses with abnormal development. 1. blue-purple, soft mass; 2. compressible; 3. positive postural metastasis test, i.e., when the tumor is below the heart level, the blood flow is blocked and the tumor increases; when the tumor is above the heart level, the blood flow is smooth and the tumor shrinks. 4. venous stones can sometimes be found in the soft tumor. 5. coagulable whole blood can be drawn by puncture. Trapezius hemangioma is formed by direct anastomosis between artery and vein with significantly dilated vessel wall. 1. the tumor is high and bead-like with high surface temperature; 2. there is pulsating sensation on palpation and wind-like murmur on auscultation; 3. the pulsation and murmur disappear if the blood supply artery is pressed closed.
