Actinomycosis is a chronic suppurative and granulomatous disease caused by Actinomyces species, which normally colonize the mouth, colon, and vagina. Actinomycosis affects any organ and it is histologically characterized by sulfur granule. Most of abdominal actinomycosis develop following appendicitis, diverticulitis or perforated viscus. Abdominal actinomycosis is commonly misdiagnosed as other diseases of intestine because the clinical presentation is non-specific and the radiologic findings mimic tumor. We report a case of abdominal actinomycosis, which initially presented as hydronephrosis and finally diagnosed after laparotomy. Histological findings showed sulfur granules, chronic granulomatous inflammation, and acute inflammatory cells. In our knowledge, this is the first report in Korea of the abdominal actinomycosis associated with appendicitis and complicated with hydronephrosis.
