Abstract - Primary hepatic actinomycosis mimicking a tumor (inflammatory pseudotumor): Case report and literature review

摘要

Actinomycosis often manifests with abscesses in the cervicofacial region. Hepatic involvement occurs usually second­ary to an intraabdominal infection. “Isolated or primary hepatic actinomycosis (PHA) defines actinomycosis in which the source of infection cannot be demonstrated elsewhere. Herein, we aimed to highlight hepatic actinomycosis in the differential diagnosis of hepatic mass lesions, and also its occurrence even in patients without underlying risk factors. A 24-year-old man, who presented with epigastric and right-upper-quadrant abdominal pain, fever, weight loss, and had a tumor-like mass in the liver was admitted to our hospital. He had no predisposing risk factors or comorbidities. We reviewed all the cases with PHA, who had no predisposing risk factors, in English medical literature from 1993 to 2014. Actinomycotic hepatic pseudotumors should be considered in the differential diagnosis of solitary liver lesions even in patients without any predisposing factors. Multi-disciplinary approach is important in the diagnosis and management.
