Petechiaalsed

Petechiae are small, pinpoint hemorrhages that appear on the skin or mucous membranes. They are typically less than 3 millimeters in diameter and are often described as tiny red or purple spots. Petechiae are a common clinical sign and can be caused by various underlying conditions, including bleeding disorders, infections, and certain medications. They are usually painless and do not blanch with pressure, unlike purpura, which are larger and do not blanch. Petechiae can be found in different locations, such as the skin, mucous membranes, or even within the eyes, and their presence can indicate a range of health issues. Diagnosis often involves a thorough medical history and physical examination, along with appropriate laboratory tests to identify the underlying cause. Treatment depends on the underlying condition and may include addressing the primary cause, such as managing a bleeding disorder or treating an infection.
