Klippel-trenaunay syndrome: a rare cause of intermittent lower gastrointestinal bleeding

Bleeding per rectum is an uncommon but potentially serious complication.

The patient did not seek any help for gastrointestinal bleeding until his admission to our unit. He was also having gigantism of his right leg and port wine angiomatous spots on his buttocks and leg.
