It consists of blood sinuses of different sizes and enlarged vascular cavities. The blood sinus is spongy, full of venous blood, and the boundary of vascular cavity is clear. There were no obvious clinical symptoms at the initial stage of the disease, and with the further deterioration of the disease, soft masses appeared.
The lump will continue to grow, gradually congestion, increase. When the head is low, the congestion of the mass is obviously enlarged, but with the change of body position, it returns to normal and the mass will return to its original state. The tumor has a bluish purple surface, shallow position, unclear boundary, soft texture and no obvious tenderness when fingers are pressed. When squeezed, the tumor is smaller than usual, but when the pressure is removed, it will return to its original shape.

Etiology of cavernous hemangioma:
1, abnormal tissue differentiation
During embryonic development, especially in the early stage of vascular tissue differentiation, the local dislocation of gene production leads to abnormal tissue differentiation in specific parts, which may eventually become the cause of cavernous hemangioma.
2. Estrogen content
According to long-term research and observation, the incidence of the disease in female patients is much higher than that in male patients. In the tumor tissue examination of two patients, it was found that the content of estradiol increased greatly. This substance is an estrogen in the human body, so it is related to the estrogen level.
3. Traumatic factors
In the etiology of cavernous hemangioma, if the embryonic tissue is damaged by mechanical trauma in the early stage of embryonic development, local tissue will bleed, which will lead to the transfer of some hematopoietic stem cells to other embryonic characteristic cells; Or vascular malformation caused by trauma after birth. , will lead to the formation of diseases.
