Acquired factor XIII deficiency presenting with multiple intracranial hemorrhages and right hip hematoma: A case report

BACKGROUND Factor XIII (FXIII) deficiency is a rare yet profound coagulopathy. FXIII plays a pivotal role in hemostasis, and deficiencies in this factor can precipitate unchecked or spontaneous hemorrhaging. Immunological assays for detecting FXIII inhibitors are indispensable for diagnosing acquired FXIII deficiency; however, the availability of suitable testing facilities is limited, resulting in prolonged turnaround times for these assays. CASE SUMMARY In this case study, a 53-year-old male devoid of significant medical history presented with recurrent intracranial hemorrhages and a hematoma in the right hip. Subsequent genetic analysis revealed a homozygous mutation in the ACE gene, confirming the diagnosis of acquired FXIII deficiency. CONCLUSION This case underscores the significance of considering acquired deficiencies in clotting factors when evaluating patients with unexplained bleeding episodes.
