What condition is characterized by larger red-purple lesions in the skin due to blood leakage from vessels?

Purpura is a condition characterized by the appearance of larger red-purple lesions on the skin. These lesions result from the leakage of blood from small blood vessels into the skin and other tissues. Purpura typically presents as spots that are larger than petechiae, which are tiny red or purple spots that do not blanch when pressed.

The distinction between purpura and conditions such as thrombocytopenia and hemorrhage lies in their underlying mechanisms. Thrombocytopenia refers to a low platelet count, which can lead to bleeding issues but is not specifically a type of skin lesion. Hemorrhage is a broader term encompassing various types of bleeding, including internal bleeding, and does not specifically refer to the lesions on the skin.

Thus, purpura is the most precise term among the options given to describe the specific skin condition with larger lesions caused by blood leakage. Understanding this distinction is crucial for accurately identifying and discussing related medical conditions.
