A "rare" case of melena in a 3-year-old.

Melena is a potential sign of life-threatening upper gastrointestinal bleeding; however, there are numerous substances ingested resulting in a stool appearance similar to melena. Examples of such substances include black licorice, bismuth subsalicylate, and iron supplements. We report a case of a well-appearing 3-year-old Vietnamese girl presenting to our emergency department after 2 episodes of "black, sticky" stool. The cause of her "melena" was determined after father revealed that she had ingested 2 bowls of pork blood soup during the preceding 12 hours. This case highlights the need for a careful dietary history and cultural considerations in children presenting with what may appear to be melena.
