[Spontaneous intrahepatic hematoma: an unexpected etiology].

INTRODUCTION: Diagnosis of AL amyloidosis can be complicated by the diversity and the absence of specificity of symptoms. CASE REPORT: We report a patient who presented with a non-traumatic hepatic hematoma, leading to the discovery of hepatic amyloidosis secondary to probable multiple myeloma. The originality of our report lies in the discovery of two acquired abnormalities of haemostasis: a factor X deficiency and an acquired von Willebrand syndrome, by a likely inhibitor.
CONCLUSION: Our case report is a reminder of the importance of haemostasis analysis in AL amyloidosis.
