Peliosis hepatis
A rare condition in which the liver contains multiple, randomly-distributed blood-filled spaces or cavities ranging in size from millimeters to several centimeters in diameter. Peliosis hepatis has been associated with the use of anabolic steroids and other hormones such as oral contraceptive pills. It has also been observed in association with both benign and malignant liver tumors, infections, and the use of certain medications. Although peliosis hepatis typically does not cause symptoms, rupture of the blood-filled cavities can lead to serious and potentially fatal internal hemorrhage.

Both PMD and Pelizaeus-Merzbacher-like disease (PMLD) are characterized by rapid, involuntary movements of the eye (nystagmus), impaired motor development, ataxia, and difficulty articulating. Some patients with PMLD have diverse mutations in a gene called […]
