Answer:
Option C, hematoma
Explanation:
A hematoma is an abnormal localized collection of blood, usually due to injury or a type of trauma and appearing either superficial or deep to the skin surface. Commonly, they known as bruises. Though, hematoma is the term used, the actual medical term for a bruise is ecchymosis. The treatment for a hematoma often varies depending on location, and amount of blood, and injury or trauma that caused it, and the potential underlying pathology that may indicate a separate, more serious condition.
Why Not Other Choices:
Purpura is a small bleed characteristically marked as purplish spots on the skin surface. They are smaller than traditional bruises.
A thrombus is a blood clot formation that has developed and lodged in a vessel wall within the circulatory vasculature. Thrombi cannot always be visualized like the appearance of bruises.
Petechiae are extremely small bleeds that are red in appearance but are non-blanchable -- that is with pressure they do not turn white before returning to a reddish color. These bleeds are smaller than purpura.
