A 7-year-old with recurrent epistaxis; which finding on exam would suggest an underlying medical cause?

• A. Wheezing
• B. Grade II murmur
• C. Petechiae
• D. Tonsil hypertrophy

Answer: (C)

Signaling a systemic bleeding tendency is crucial when evaluating recurrent epistaxis. Petechiae are tiny, non-blanching hemorrhages in the skin or mucosa that occur when platelets are low or not functioning or when the coagulation cascade is abnormal. Their presence means the bleeding is not just from a local nasal surface issue but from an underlying medical condition such as thrombocytopenia, a platelet function disorder, or a coagulation disorder, and it prompts further hematologic evaluation. In contrast, wheezing points to airway or allergic issues, a heart murmur may be an incidental finding or reflect hemodynamic effects but does not specifically indicate a bleeding disorder, and tonsil hypertrophy is an anatomical or infectious issue without inherently signaling systemic coagulopathy. Therefore, detecting petechiae best points to an underlying medical etiology of epistaxis.
