| Caffey-Silverman syndrome | Neonatal subperiosteal bone formation over many bones, especially the mandible and clavicles and the shafts of long bones; it follows fever, usually appearing before 6 months of age and disappearing during childhood. Synonym: Caffey's disease, Caffey's syndrome, Caffey-Silverman syndrome. (05 Mar 2000) |

| capillary leak syndrome | <syndrome> Extravasation of plasma fluid and proteins into the extravascular space, resulting in sometimes fatal hypotension and reduced oxygen perfusion. Clinical capillary leak syndrome is observed in patients who demonstrate a state of generalised leaky capillaries following shock syndromes, low-flow states, ischemia-reperfusion injuries, toxaemias, or poisoning. It can lead to generalised oedema and multiple organ failure., reperfusion injuries and clinical capillary leak syndrome. (12 Dec 1998) |

| caplan syndrome | <radiology> Combination of: necrobiotic rheumatoid lung nodules, coal worker's pneumoconiosis Findings: round, peripheral nodules (0.5 - 5.0 cm), with or without cavitation, nodules associated with subcutaneous rheumatoid nodules (12 Dec 1998) |
| carbohydrate-deficient glycoprotein syndrome | <syndrome> An inborn error of carbohydrate metabolism manifesting as a genetic multisystem disorder of autosomal recessive inheritance. A predominant feature is severe central and peripheral nervous system involvement resulting in psychomotor retardation, seizures, cerebellar ataxia, and other symptoms which include growth retardation, retinitis pigmentosa, hypothyroidism, and fatty liver. The notable biochemical feature is the deficiency of a large number of blood glycoproteins and decreased activities of various blood coagulation factors. (12 Dec 1998) |

These tumours may grow anywhere in the gastrointestinal tract (and in the lungs) with approximately 90% in the appendix. The remainder occur in the ileum, stomach, colon or rectum. Symptoms include flushing, rapid pulse, facial swelling, swelling around the eyes, low blood pressure, abdominal pain, weight loss and diarrhoea. (19 Jan 1998) |
| cardiofacial syndrome | <syndrome> Transient or persistent unilateral partial lower facial paresis accompanying some congenital heart disease. A group of syndromes characterised by congenital cardiovascular, bone, soft tissue, and facial abnormalities. Examples include Rubinstein-Taybi syndrome, Noonan's syndrome and Williams' syndrome.
