Aberrant Tissue location?

Aberrant Tissue location?

• A. It can be located in the liver
• B. It can be located in the duodenum, stomach, and small bowel
• C. It occurs in the spleen
• D. It occurs in the heart

Answer: (B)

Aberrant tissue means tissue that’s located where it doesn’t normally reside, a form of ectopic or heterotopic tissue. In the abdomen, this most often refers to gastric-type mucosa appearing within parts of the gastrointestinal tract, such as in duplication cysts or related anomalies. That makes locations within the GI tract—the duodenum, stomach, and small bowel—the typical sites where aberrant tissue can be found. In contrast, the liver, spleen, and heart are solid organs where GI mucosa isn’t normally expected, so they aren’t the usual locations for aberrant GI tissue.
