Hello,
I see you are asking "What is blue rubber bleb nevus?"
Blue rubber bleb nevus syndrome (BRBNS), sometimes called Bean syndrome, is a rare congenital vascular anomaly in which malformed veins, or blebs, appear on the skin and surfaces of internal organs. These small, purple lesions are particularly common in the gastrointestinal (GI) tract.
