Poorly cohesive cell (diffuse-infiltrative/signet-ring cell) carcinomas of the gallbladder
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.
PCC carcinoma originating in the gallbladder should be kept in mind for the differential diagnosis of disseminated poorly differentiated carcinomas in the abdomen.
