DIFFUSE ORAL PETECHIAL HEMORRHAGE AND DIAGNOSTIC CHALLENGES

Diffuse petechial hemorrhage of the oral mucosa is uncommon. Diffuse petechial hemorrhages in the oral cavity are numerous small, pinpoint red spots (petechiae) that appear on the oral mucosa, often caused by damaged capillaries due to injury, infection, medication, or hematologic disorders (platelet problems, leukemia, bleeding disorders). Repeated negative pressure and trauma to the soft tissues of the oral cavity are sufficient to produce these pinpoint hemorrhages, especially along the soft palate, and sometimes extending to the hard palate or tongue. Diffuse petechial hemorrhages are often harmless and resolve on their own, especially after injury; however, widespread or spontaneous petechiae require evaluation with blood tests (complete blood count, coagulation profile) to differentiate and exclude serious systemic diseases, as they may indicate bleeding disorders or vascular problems. These tests are necessary to accurately determine the cause of petechiae, ensuring an accurate diagnosis and effective treatment. These petechiae, as a rule, are harmless and usually resolve on their own within a few days. We present an 82-year-old male with petechiae of the palate and left buccal mucosa. Complete blood count was ordered and ruled out a hematologic disorder. A thorough review of the potential source of trauma led to the identification of excessive negative pressure and forceful thrusting as the cause. Petechiae were resolved after the patient stopped the habit.
