Presentation

BRBNS is a venous malformation, formerly, though incorrectly, thought to be related to the hemangioma. It carries significant potential for serious or fatal bleeding. Lesions are most commonly found on the skin and in the small intestine and distal large bowel.

Causes

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

History

It was first described by Gascoyen in 1860.^[1] In 1958 William Bennett Bean described the lesions further and came up with the term BRBNS, chosen because the 'cutaneous hemangiomas have the look and feel of rubber nipples'.^[2]
