A common clinical hemangioma is a relatively common benign tumor of mesodermal origin that can grow anywhere on the body, but most grow in the skin and subcutaneous tissues and are therefore easier to detect. Vascular tumors are one of the tumors of the vasculature, which develop from the mesoderm. If the vasculature develops abnormally during embryonic development, these primitive cells remain discrete in abnormal areas and continue to develop as hemangiomas. Generally, hemangiomas located in the skin or superficial muscular layer are called body surface hemangiomas, and can be divided into the following types: 1, simple (strawberry-shaped) hemangioma: often appear within 1-2 months after birth, preferably on the face, gradually increasing in size within a few months, mainly in the dermis, with varying sizes and generally clear borders, sometimes surrounded by “spider leg”-like capillary extension. Localized slightly higher than the surface, there are also strawberry-like, bright red or purple-red color, soft texture. 2. Capillary nevus (or vivid red nevus): They are found at birth or occur soon after birth, usually on the face and neck, generally not higher than the skin surface, with clear borders, varying in shape and size, from small to pinpoint size to the whole trunk, with scattered distribution or patch-like or geoglyphic distribution, and varying in color from light red, deep red to purplish red. The color varies from light red, dark red to purplish red. The color may recede after local pressure is applied, and regains its original color soon after the pressure is removed. These hemangiomas develop very slowly and the lesions are within the skin layer. 3.Cavernous hemangioma: It usually occurs at birth or soon after, and it is usually found on the head, face and trunk. The lesion is mainly in the subcutaneous soft tissues and is nodular or lobulated, which can be higher than the skin surface or deeper, and the surface skin can be normal in color or light purple or purple-blue. In addition to the clinical manifestations of cavernous hemangioma, its pathology is characterized by rich arteriovenous communication and often thicker caliber arteries, so the mass often feels throbbing when touched. 5.Mixed hemangioma: It refers to the hemangioma with two pathological types of components at the same time, and its clinical manifestations depend on the pathological type that accounts for the main component.
