A 4-Year-Old With Recurrent Epistaxis and a Normal Coagulation Screen
A 4-year-old girl is brought to the clinic by her mother with recurrent nosebleeds for 6 months. The bleeding occurs mostly at night and is sometimes severe enough to stain the pillow. She has no bruising, no gum bleeding, and no family history of bleeding disorders. A complete blood count and coagulation screen are normal. On examination, the nasal mucosa is pale and there is a visible vessel on the anterior nasal septum on the left side. The mother is worried about leukemia and asks for a bone marrow test. The child is otherwise healthy and growing normally.
1. What is the most likely diagnosis, and how would you explain it to the mother?

The most likely diagnosis is recurrent anterior epistaxis from Little's area, likely related to digital trauma (nose picking), dry air, or a prominent septal vessel. The normal CBC and coagulation screen make a bleeding disorder or leukemia unlikely. The visible vessel on the anterior septum supports this.
Explanation to the mother:
- "Your daughter has a small blood vessel on the inside of her nose that keeps breaking open. This is common in children and is not a sign of leukemia."
- "The blood tests are normal, which is reassuring."
- "We can treat this with simple measures: keeping the nose moist, avoiding nose picking, and using a nasal saline spray or petroleum jelly."
- "If bleeding continues, we can cauterize the vessel in the clinic."
- "Leukemia would usually cause bruising, fatigue, fever, or abnormal blood counts, which she does not have."
Avoid unnecessary bone marrow testing. Reassure the mother and provide a clear management plan.
2. How would you manage the epistaxis in the clinic, and what would you do if cauterization fails?

Initial management:
- First aid: Pinch the soft part of the nose for 10–15 minutes, lean forward, and apply a cold pack.
- Topical vasoconstrictor and anesthetic: Apply cotton wool soaked in lidocaine with adrenaline to the bleeding point for 5–10 minutes.
- Cautery: Use silver nitrate cautery or electrocautery to the vessel, avoiding both sides of the septum to prevent perforation.
- Lubrication: Prescribe nasal saline spray or petroleum jelly to prevent dryness.
- Avoidance: Advise against nose picking, blowing forcefully, and strenuous activity for 1–2 weeks.
If cauterization fails:
- Reassess for a bleeding disorder (von Willebrand disease, platelet function disorder) with a hematology referral.
- Consider nasal packing with absorbable material (e.g., NasoPore) or anterior packing.
- If bleeding is severe or recurrent, consider examination under anesthesia and endoscopic cautery.
- In rare cases, arterial embolization or ligation may be needed, but this is uncommon in children.
3. What would make you suspect a bleeding disorder, and what tests would you order?
Read the worked answer
Suspect a bleeding disorder if there is:
- A family history of bleeding disorders.
- Bleeding from other sites (gums, gastrointestinal tract, easy bruising).
- Bleeding after surgery or dental extraction.
- Petechiae or purpura.
- Prolonged bleeding despite adequate local measures.
- Onset in infancy or after starting a new medication.
Tests:
- Full blood count and peripheral smear.
- Prothrombin time (PT) and activated partial thromboplastin time (aPTT).
- von Willebrand factor antigen and activity (ristocetin cofactor).
- Platelet function tests if von Willebrand disease is suspected.
- Factor VIII and IX levels if hemophilia is suspected.
- Referral to pediatric hematology if any abnormality is found.
