Signet-ring cell carcinoma; diffuse-infiltrative carcinoma; PCC carcinoma

Definition: Signet-ring cell carcinoma is a type of adenocarcinoma.

In the gastrointestinal system, carcinomas with single-cell or cord-like infiltration, previously called “diffuse-infiltrative” type or “signet-ring cell”, are now designated as “poorly cohesive cell” (PCC) type (regardless of with/without signet-ring cells) in the WHO-2010 classification.
