Peliosis hepatis

Peliosis hepatis is an uncommon vascular condition characterised by multiple randomly distributed blood-filled cavities throughout the liver. The size of the cavities usually ranges between a few millimetres to 3 cm in diameter. 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.
