Verified step by step guidance

Step 1: Begin by understanding the key terms in the question. A 'massive hemorrhage into subcutaneous tissue' refers to a significant amount of blood leaking into the tissue beneath the skin.

Step 2: Define each option provided in the question: - Abscess: A localized collection of pus caused by infection. - Ulcer: An open sore or lesion on the skin or mucous membrane. - Edema: Swelling caused by excess fluid trapped in the body's tissues. - Hematoma: A localized collection of blood outside the blood vessels, often caused by trauma.

Step 3: Compare the definitions to the description in the question. A 'massive hemorrhage into subcutaneous tissue' aligns most closely with the definition of a hematoma, as it involves blood pooling outside the vessels.

Step 4: Eliminate the incorrect options based on their definitions. Abscess, ulcer, and edema do not involve blood pooling due to hemorrhage, so they are not correct.

Step 5: Conclude that the correct answer is 'hematoma,' as it matches the description of a massive hemorrhage into subcutaneous tissue.
