A tumor-like mass/swelling made up of blood is called...

• A. Hematoma.
• B. Hemorrhage.
• C. Thrombus.
• D. Anemia.

Answer: (A)

A hematoma is a localized collection of blood outside the vessels, usually forming a lump after vessel rupture and blood leakage into the tissue that then clots. This creates a tumor-like swelling simply because blood has pooled in one area, not because it’s a true tumor. It differs from a hemorrhage, which is the act of bleeding itself rather than the accumulated blood. A thrombus is a clot that forms inside a vessel and stays there, potentially blocking flow, not a mass of blood outside vessels. Anemia is a systemic condition of insufficient red blood cells or hemoglobin, not a lump. So the lump-like mass made up of blood describes a hematoma.
