GI Pathology
GI Pathology: In gastrointestinal (GI) pathology, IHC is critical for diagnosing cancers like colorectal adenocarcinoma, gastric cancer, and gastrointestinal stromal tumors (GISTs). Markers like CD117, CD34, and MUC2 help distinguish between tumor types, while mismatch repair (MMR) proteins can indicate hereditary conditions like Lynch syndrome.
