Purpura and Petechiae – Understanding the Differences

Purpura and petechiae are types of bruises that occur due to bleeding underneath the skin. Purpura refers to larger, flat bruises that measure more than 1 centimeter in diameter, while petechiae are tiny pinpoint spots that result from capillary bleeding. These types of bruises can be a warning sign of an underlying medical condition, such as a blood clotting disorder or a weakened blood vessel. If you develop purpura or petechiae without any apparent injury or trauma, it is crucial to consult a healthcare professional for a thorough evaluation and appropriate diagnostic testing.
