What is a hemangioma?

Hemangioma is a relatively common vascular lesion in clinical practice, exhibiting characteristics of either a benign tumor or congenital vascular malformation. Hemangiomas are mainly classified into two categories: 1. True hemangioma: Mostly benign tumors, primarily caused by excessive proliferation or structural disorder of vascular tissue during fetal development in utero. 2. Vascular malformations: Including venous malformations, arterial malformations, etc., such as cavernous hemangioma and capillary hemangioma. Hemangiomas can occur throughout the body, most commonly found in the skin, mucous membranes, and soft tissues. Locally, they often appear as purplish or bright red patches with irregular shapes and indistinct borders. Treatment options for hemangiomas are varied and include cryotherapy, sclerotherapy, laser therapy, radiotherapy, and surgical treatment, with the specific approach determined according to the patient's condition.
