Peliosis hepatis is a condition characterized by blood-filled lesions in the liver that can be localized or diffuse in distribution. The predisposing factors for this condition include treatment with anabolic steroids, chemotherapeutic and oral contraceptive agents, catabolic metabolic conditions (e.g., hypoglycemia) and certain immunological disorders. This disease probably represents a non-specific immunological response to a variety of noxious agents and has been successfully induced in experimental animals. The increased tendency towards liver rupture following blunt trauma and resuscitation procedures may have important medicolegal consequences. We present a case of peliosis hepatis in a patient with type I glycogen storage disease (von Gierke).
