Haemorrhagic Cholecystitis: A Rare Form of Haemorrhagic Shock in a Patient With a Double Risk.

Haemorrhagic cholecystitis is an uncommon condition with varied clinical presentations and several risk factors, such as anticoagulation, coagulopathy, malignancy, and trauma. We describe the clinical case of a 43-year-old man with two risk factors, anticoagulation and haemophilia B, who presented with atypical symptoms that progressed to shock. Diagnosis and therapeutic approach made this case particularly challenging. This condition should be a diagnosis to consider in a patient with relevant risk factors.
