Blue rubber bleb nevus syndrome (or "BRBNS", or "blue rubber bleb syndrome, or "blue rubber-bleb nevus", or "Bean syndrome") is a rare disorder that consists mainly of abnormal blood vessels affecting the gastrointestinal tract.

It was characterized by William Bean in 1958.[1][2][3]

Presentation

BRBNS is a venous malformation,[4] formerly, though incorrectly, thought to be related to the hemangioma. It carries significant potential for serious bleeding.[5] Lesions are most commonly found on the skin and in the small intestine and distal large bowel. It usually presents soon after birth.[6] Although no genetic link has yet been determined, it has been suggested that it may represent a manifestation of familial venous malformation, and may be associated with TEK tyrosine kinase.[7][8]

Causes

The causes of this syndrome are unknown. Not more than a few hundred cases have been described worldwide.
