Simple hemangioma
is usually red or blue-purple color, is located on the surface, clearly delineated boundaries, affects the skin and a few millimeters of subcutaneous fat layer, usually grows in hand. Rare hemangioma uneven, slightly protruding above the skin (usually smooth). One symptom of hemangiomas is that if you push on it, it is for a short period of time fades, then again takes its color.

Cavernous hemangioma
is usually located under the skin, is a limited nodular formation, soft-elastic consistency. Consists of various cavities - caverns filled with blood. Look cavernous hemangioma as tumor formation, on top of the usual skin color, sometimes bluish. With the growth of the tumor skin becomes blue-purple color. When pressed on the hemangioma she falls and thus a bit pale (due to the outflow of blood). When you cry and cough hemangioma increases.

Combined hemangioma
usually a combination of surface and subcutaneous hemangiomas (simple and cavernous). Detected by the prevalence of one or the other of the tumor vasculature. Appearance and consistency, again, depends on its constituent tissues.

Microscopic structure of capillary hemangioma. The wall of the capillaries represented two-three-layer endothelium (tissue atypia), the cavity often filled with blood.

Cavernous Hemangioma of the Maxillary andEthmoid Sinus

Gross appearance of the sclerosed hemangioma of liver. A gray-white sunken nodule is noted in the subcapsular area (A). The cut surface discloses a well-demarcated homogenous gray-white solid nodule, measuring 2.1 cm at its greatest dimension, with tiny red spots (B).
