Overview

Peliosis Hepatis is an uncommon vascular condition characterised by randomly distributed multiple blood-filled cavities throughout liver. Size of the cavities usually ranges between a few millimetres to 3 cm in diameter[1]. In the past it was a mere histological curiosity occasionally found at autopsies but has been increasingly recognised with wide ranging conditions from AIDS to the use of anabolic steroids. It also occasionally affects spleen, lymph nodes, lungs, kidneys, adrenal glands, bone marrow and other parts of gastrointestinal tract.[2].

Peliosis hepatis is often erroneously written "peliosis hepatitis", despite its not being one of the hepatitides. The correct term arises from the Greek pelios, i.e. discoloured by extravasated blood, livid[3], and the Latinized Genitive case (hepatis[4]) of the Greek hepar, liver[5].

Pathophysiology

The pathogenesis of peliosis hepatis is unknown. There are several hypotheses, such as, it arise from sinusoidal epithelial damage[6], increased sinusoidal pressure due to obstruction in blood outflow from the liver, or hepatocellular necrosis[1].

Two morphologic patterns of hepatic peliosis were described by Yanoff and Rawson [7]. In the phlebectatic type, the blood-filled spaces are lined with endothelium and are associated with aneurismal dilatation of the central vein; in the parenchymal type, the spaces have no endothelial lining and they usually are associated with haemorrhagic parenchymal necrosis. Some considers both pattern to be one process, initiated by focal necrosis of liver parenchyma observed in parenchymal type progressing into formation of fibrous wall and endothelial lining around haemorrhage of phebectatic type. Fibrosis, cirrhosis, regenerative nodules, and tumours may also be seen.

Clinical features

The condition is typically asymptomatic and is discovered following evaluation of abnormal liver function test. However, when severe it can manifest as jaundice, hepatomegaly, liver failure and haemoperitoneum.

Treatment

Antimicrobial regimen

  • Bacillary peliosis hepatitis (peliosis hepatis caused by Bartonella spp.)[14]
  • Preferred regimen (1): Clarithromycin 500 mg bid for 4 months
  • Preferred regimen (6): Erythromycin 500 mg PO qid for 4 months
  • Preferred regimen (2): Doxycycline 100 mg PO bid for 4 months
  • Special Consideration
  • Severe disease
  • Preferred regimen: Doxycycline 100 mg PO/IV bid for 4 months AND Rifampin 300 mg PO bid for 4 months
