Verified step by step guidance

Understand the definitions of each term provided in the question to differentiate them.

Edema refers to the accumulation of fluid in the tissues, causing swelling. It is not related to clotted blood.

Abscess is a localized collection of pus caused by infection, typically surrounded by inflamed tissue. It does not involve clotted blood.

Hematoma is the correct term for swelling caused by clotted blood trapped in the tissues. It occurs when blood vessels are damaged, leading to blood pooling and clotting in the surrounding tissue.

Lymphadenopathy refers to the enlargement of lymph nodes, often due to infection or other conditions, and is unrelated to clotted blood or swelling in tissues.
