Is cavernous hemangioma hereditary?

Hemangioma is a relatively common tumor that people encounter in daily life. It is mainly distributed in people’s capillaries and veins, and poses a great threat to some people’s bodies. Cavernous hemangioma is one of the more common hemangiomas. Sometimes this type of hemangioma can be fatal to people's bodies. When many people suffer from cavernous hemangioma, they are afraid that this tumor will be passed on to their offspring. So is cavernous hemangioma hereditary?

What is a cavernous hemangioma?

Cavernous hemangioma is common in infancy or childhood. It is a congenital developmental malformation that will continue to proliferate as the child grows and may even invade the subcutaneous tissue, bones, and muscles, affecting the child's health and growth. During the development of individual embryos, especially in the early stage of vascular tissue differentiation, small-scale misconfiguration of the controlling gene segment leads to abnormal tissue differentiation in specific parts and the development of cavernous hemangioma.

Cavernous hemangioma is a large, elevated, blood-filled vascular tumor with a large number of red blood cells in the lumen, so it feels spongy to the touch, shrinks when pressed, and becomes congested and bulges again when released. It can protrude from the skin surface, be buried deep in the subcutaneous tissue, or rupture and bleed continuously.

Cavernous hemangioma is composed of numerous blood sinusoids lined with endothelial cells. The blood sinusoids vary in size and shape, like a sponge. The sinus cavities are filled with venous blood and communicate with each other. Sometimes the blood in the sinus cavity coagulates and forms a thrombus, which can calcify into a phlebolith. Cavernous hemangioma often occurs on the cheeks, neck, eyelids, lips, tongue or bottom of the mouth. When the location is deep, the skin or mucous membrane is normal in color; when the tumor is superficial, it appears blue or purple.

Is cavernous hemangioma hereditary?

Cavernous hemangiomas are vascular malformations with low blood flow that are present at birth, also known as venous malformations. Vascular damage generally develops slowly, often increasing in childhood or adolescence, but not significantly in adulthood. Most venous malformations are cavernous in shape, hence the name cavernous hemangioma.

Cavernous hemangioma has a genetic tendency, but it is not 100% inherited. In clinical practice, we do encounter cases where several generations of a family have cavernous hemangioma. This shows that the genetic gene for cavernous hemangioma does exist. Regarding the hereditary nature of cavernous hemangioma, what patients with cavernous hemangioma can do is, if they suffer from cavernous hemangioma, first treat and recover before choosing to have children. If patients with cavernous hemangioma already have children, they should check their children regularly to ensure early detection and early treatment.

To sum up, although cavernous hemangioma is not 100% hereditary, it still has a certain degree of heritability, so everyone must pay attention to cavernous hemangioma. Once a hemangioma is found, it must be treated in time.
