A Case of Esophageal Actinomycosis in a Patient with Diabetes Mellitus / 대한내과학회지

A 47-year-old patient with diabetes mellitus was admitted with the complaints of sore throat and dysphagia. We performed an esophagogastroduodenoscopy and found esophageal ulcers. Histological examination of the esophageal biopsy revealed sulphur granules, and immunological findings ruled out viral infection. Thus, we diagnosed an isolated actinomycotic infection of the esophagus and treated the infection with oral amoxicillin. This case illustrates that actinomycotic infection of the esophagus can occur in immunocompetent patients. Therefore, when evaluating dysphagia, the probability of actinomycotic infection must be considered not only in immunocompromised patients, but in immunocompetent individualswith diabetes mellitus.
