Spontaneous Perforation of an Unknown Esophageal Diverticulum in a Hemodialysis Patient

Zenker’s diverticulum is a rare disease, with an annual incidence of about 2 cases per 100000, occurring most often in elderly men. No data are reported in dialysis patients. We report a case of a hemodialysis patient who experienced a sudden spontaneous perforation of an unknown esophageal diverticulum. To our knowledge, this is the first case reported in a hemodialysis patient. Its description could be helpful to consider in such patients the possibility of the perforation of an esophageal diverticulum when typical symptoms are referred in addition to the exclusion of other events with similar symptoms (acute esophagitis and gastroduodenitis, perforated peptic ulcer, acute pancreatitis, myocardial infarction, pneumothorax, dissecting aortic aneurysm).
