| chocolate cyst | Cyst of the ovary with intracavitary haemorrhage and formation of a haematoma containing old brown blood; often seen with endometriosis of the ovary but occasionally with other types of cyst's. (05 Mar 2000) |
| chocolate poisoning | Poisoning, most commonly of dogs, by ingestion of excessive quantities of chocolate (especially unsweetened baker's chocolate); the causative toxin is theobromine which produces thirst, vomiting, diarrhoea, urinary incontinence, chronic muscle spasms, seizures, and coma.
