Purple bowel misdiagnosed as intestinal hemorrhage.

Summary: Imagine a forensic pathologist discovering a purple, blood-stained intestine during an autopsy. The immediate suspicion is internal bleeding or traumatic injury. However, this report reveals a surprising culprit: beetroot. In a rare phenomenon, pigment from beetroot ingested before death can passively diffuse through the intestinal wall after death, mimicking a hemorrhage. Crucially, unlike real blood, this purple discoloration vanishes when the tissue is preserved in formalin for testing. This case serves as a vital lesson for medical examiners: sometimes, alarming visual evidence is simply a dietary artifact, not a sign of foul play.
