Malignant atrophic papulosis (Q104321): Difference between revisions

Degos' disease (malignant atrophic papulosis) is a rare, progressive occlusive vasculopathy of unknown cause affecting small and medium calibre arteries. Its protean manifestations result from focal tissue infarction in skin and other organs. It presents initially in the skin as scattered small pink papules which undergo ischaemic necrosis to leave characteristic circular porcelain-white scars. Although it may remain limited to the skin, it tends over time to progress to involve other organ systems. Multiple focal infarcts in the CNS may result in a wide variety of neurological sequelae. Gastrointestinal bleeding and perforation are the most common causes of death.
