Hematoma

,

A pool of blood outside the blood vessels.

, Description

A hematoma may be small, just under the skin’s surface and look like a bad bruise. Or it may be large and deep inside the body. Hematomas can happen anywhere in the body, including the brain. An injury, such as from an accident or a surgery may cause a hematoma. Some hematomas are life-threatening.

Overview

Symptoms vary depending on the location of the hematoma. When the hematoma is in or just beneath the skin, symptoms may include a bruise with a lump, swelling, changes in skin color, and pain.

Symptoms

Treatment depends on the location, size and cause of the hematoma. Mild hematomas often go away on their own. Severe hematomas that happen after a major accident, such as a blow to the head, need emergency care. Sometimes surgery is needed.
