Hematoma is characterized by which of the following symptoms?

A hematoma is characterized by the accumulation of blood outside of blood vessels, usually due to a rupture or leakage following injury or trauma. The symptoms of a hematoma commonly include swelling and tenderness at the site of the injury, which occurs as blood collects and causes localized inflammation and discomfort. Additionally, bleeding from the site may be present initially or may continue to occur if there is ongoing damage to the vessels. Furthermore, pain and discoloration are also typical symptoms, as the trapped blood can create a bruise-like appearance, changing color over time as the body reabsorbs the blood.

Thus, since a hematoma presents all these symptoms—swelling, tenderness, possible bleeding, pain, and discoloration—selecting all of the above is accurate. Each symptom plays a role in the clinical presentation of a hematoma, collectively signaling the presence of this condition.
