| pancreatic isleT-cell tumours | <radiology> Insulinoma (beta-cell), usually solitary, 85% benign, gastrinoma, small, slow-growing, multiple, 60% malignant, Zollinger-Ellison syndrome: mult. Intractable ulcers, VIPoma, vasoactive intestinal peptide (VIP), WDHA syndrome: watery diarrhoea, hypokalaemia, achlorhydria, Verner-Morrison syndrome, glucagonoma, hyperglycaemia, migratory necrolytic erythema APUDomas, associated with MEN-1 (12 Dec 1998) |
| Paneth cell | <pathology> Coarsely granular secretory cells found in the basal regions of crypts in the small intestine. (18 Nov 1997) |

| veil cell | An antigen-presenting cell that has veil-like cytoplasmic processes and circulates in the blood and lymph. Synonym: veiled cells. (05 Mar 2000) |
| veiled cell | A cell type found in afferent lymph and defined (rather unsatisfactorily) on the basis of its morphology. Probably an accessory cell migrating from the periphery (where it is referred to as a Langerhans cell if in the skin) to the draining lymph node. In the lymph node known as an interdigitating cell and found in the T dependent areas of spleen or lymph nodes, involved in antigen presentation (Class II MHC positive). Has high levels of surface Ia antigens. (18 Nov 1997) |
