Case of Esophageal Actinomycosis Occurred after Endoscopic Mucosal Resection for Subepithelial Tumor

Korean J Gastroenterol. 2023 Sep 25;82(3):137-139. doi: 10.4166/kjg.2023.068.ABSTRACTEsophageal actinomycosis is a rare, chronic granulomatous disease caused by Actinomyces species. Endoscopy and biopsy are essential for making a diagnosis. This paper reports a case of esophageal actinomycosis that developed after an endoscopic mucosal resection (EMR) for a subepithelial tumor (SET). A 74-year-old male patient had a 3 cm flat, smooth elevation in the esophagus without symptoms. The SET was partially resected, and histology revealed "nonspecific degenerated mesenchymal tissue". Three months later, the patient exhibited a persistently large ulceration at the EMR site, and a biopsy revealed actinomycosis. CT of the chest and abdomen revealed no abnormal findings. Ampicillin treatment was administered for six months, and the ulceration on the esophageal SET improved.PMID:37743812 | DOI:10.4166/kjg.2023.068
