A hematoma refers to the accumulation of blood outside the blood vessels, resulting in pain, discoloration, and swelling. Although they may resemble bruises, hematomas are generally more severe, characterized by their larger size, deeper location, and the accumulation of fluid in the affected area. The severity of a hematoma and the need for immediate treatment largely depend on its location within the body.
Causes
Hematomas occur as a result of various causes, with trauma being the most common trigger. Incidents like motor vehicle accidents and falls often lead to hematoma formation. Additionally, certain factors can increase the risk of bleeding and make hematomas more severe. Liver disease, blood thinners, and certain medications are known to heighten the chances of hematoma occurrence and worsen the condition when trauma happens. While rare, spontaneous hematomas can also develop, indicating the presence of underlying medical issues of a more serious nature.
Subdermal Hematoma: Causes, Symptoms, and Treatment
A subdermal hematoma, also known as a bruise, occurs when blood accumulates beneath the skin without breaking the skin’s surface. These hematoma formations can arise on any part of the body that experiences trauma or injury. The characteristic signs of a subdermal hematoma typically manifest immediately after the injury or may appear a few days later. Identification is relatively straightforward, as it presents as a distinct purplish-red discoloration beneath the skin, accompanied by swelling, tenderness, and pain.
