Abstract
Colloid carcinoma pancreas is an infiltrative ductal epithelial neoplasm of the pancreas characteristically denominating a preponderant (> 80%) component of enlarged pools of extracellular stromal mucin pervaded with suspended neoplastic cells. Colloid carcinoma pancreas is a microsatellite stable tumefaction and exhibits KRAS genetic mutation confined to codon 12. Tumefaction is posited to arise from the inverse polarization of cells with stromal mucin glycoproteins facing the intrinsic cellular surface. Cogent clinical symptoms such as abdominal or epigastric pain, pancreatitis, diarrhoea, hyperbilirubinemia or loss of weight are discerned. Tumefaction emerges as an enlarged, well-demarcated lesion with a mean diameter of 5 centimetres and a solid, firm, gelatinous cut surface. Neoplasm is predominantly comprised of enlarged, extracellular accumulates of stromal mucin with minimal carcinoma cells suspended within extra-cellular mucin pools. Cuboidal or columnar epithelial cells configure cribriform or stellate cellular clusters or miniature tubules and strips of columnar cells along with signet ring cells.
