Pseudomelanosis of the duodenum is rare. Only 17 cases have been documented in the world literature. A 59-year-old man presented to Bankstown Hospital, New South Wales with dysphagia. On endoscopy, he was found to have melanosis of the duodenum in addition to oesophageal ulceration. It has been previously suggested that the pigment ferrous sulphide is derived from gastro-intestinal bleeding and lodged in the macrophages. A detailed examination of the pigment, including X-ray probe micro-analysis at various levels of the intestinal epithelium as well as in macrophages is presented.
十二指肠假黑色素沉着症很罕见。世界文献中仅记载了17例。一名59岁男性因吞咽困难就诊于新南威尔士州班克斯敦医院。内镜检查发现，他除了有食管溃疡外，还有十二指肠黑色素沉着症。此前有人提出，色素硫化亚铁源自胃肠道出血并沉积于巨噬细胞中。本文对该色素进行了详细检查，包括在肠道上皮细胞不同层面以及巨噬细胞中进行X射线探针微分析。
