Extensive gastric ulceration was diagnosed endoscopically and histologically in a two-year-old cat with haematemesis, anorexia and severe dehydration. Based on history (previous ingestion of leaf pieces of Dieffenbachia) and exclusion of another cause, intoxication with Dieffenbachia was diagnosed. The toxical effect of Dieffenbachia on mucous membranes is probably explained by ejection of calcium oxalate crystals leading to injury of mast cells and a massive histamine release. Supportive treatment including electrolyte infusions, ranitidine, sucralfate, and forced feeding using an endoscopically placed gastrostomy tube resulted in quick clinical recovery of this cat.
一只两岁的猫出现呕血、厌食和严重脱水症状，经内镜检查和组织学检查诊断为广泛性胃溃疡。根据病史（此前摄入了花叶万年青的叶片）并排除其他病因后，诊断为花叶万年青中毒。花叶万年青对黏膜的毒性作用可能是由于草酸钙晶体的排出导致肥大细胞损伤和大量组胺释放所致。支持性治疗包括输注电解质、使用雷尼替丁、硫糖铝，并通过内镜放置胃造瘘管进行强制喂食，这只猫最终迅速康复。
