What term describes micro hemorrhages that appear as red spots on the skin?

The term that describes micro hemorrhages appearing as red spots on the skin is petechiae. Petechiae occur when small blood vessels, or capillaries, break and leak blood into the skin, creating tiny, pinpoint red or purple spots. These spots can indicate various underlying health issues, ranging from minor problems like physical strain to more serious conditions related to blood clotting disorders or infections.

In contrast, leucoderma refers to a loss of pigment in the skin, often resulting in white patches, which is not related to blood vessel damage. Hypertrophy describes an increase in the size of an organ or tissue, generally due to an increase in the size of its cells, and does not pertain to micro hemorrhages. Keratosis refers to a condition characterized by the growth of keratin on the skin, which can cause rough, scaly patches but is unrelated to red spots caused by bleeding. Understanding these distinctions helps in recognizing skin conditions more accurately.
