According to the literature, cells of acinar cell carcinoma of the pancreas contain cytokeratins 8 and 18, and these two cytokeratins react with broad spectrum cytokeratin antibodies such as AE1/AE3, which has been demonstrated in human, canine, and feline acinar cell pancreatic carcinomas [12,14,15,16,17,18]. The gene discussed is SLC4A3; the disease is pancreatic acinar cell carcinoma.
