ABSTRACT Factor XIII deficiency is a rare cause of bleeding disorder. An 8‐month‐old male infant presented with persistent bleeding from a minor lip cut injury, which was sustained 2 days prior. The bleeding did not stop despite local hemostatic measures. His medical history was notable for spontaneous intradermal bleeds at different times and umbilical stump bleeding during the neonatal period. On examination, there were multiple petechiae and a large ecchymosis over the chest. Routine hematological and coagulation parameters were within normal limits. von Willebrand factor, factor VIII, and factor IX levels were normal. However, a qualitative 5M urea clot solubility test followed by factor XIII assay yielded abnormal results, confirming factor XIII deficiency. The patient was managed with fresh frozen plasma (FFP) and supportive care. Four months later, the patient presented with lethargy and vomiting, later diagnosed as epidural hematoma. The patient received FFP, had a favorable stay in the pediatric intensive care unit, and was discharged with no neurological deficits and a prophylactic plan. This case underscores how factor XIII deficiency can elude detection in routine coagulation tests, emphasizing the importance of prompt diagnosis and timely administration of replacement therapy to prevent complications and associated constraints in a resource limited setting.
