{Reference Type}: Case Reports {Title}: A rare case report of liver masses caused by Actinomyces species. {Author}: Siregar DRG;Kawilarang AP;Kusumaningrum D;Purwanta M; {Journal}: Indian J Med Microbiol {Volume}: 49 {Issue}: 0 {Year}: 2024 May-Jun 3 {Factor}: 1.347 {DOI}: 10.1016/j.ijmmb.2024.100573 {Abstract}: Actinomycosis is a rare infection caused by Actinomyces spp. Of all actinomycosis infections, only 5% of Hepatic Actinomycosis (HA) infection has been reported. This disease is often misdiagnosed as a malignancy. This case report presents a 45-year-old woman with diabetes, initially suspected of intrahepatic cholangiocarcinoma, but after careful tissue staining, we found the results supported HA infection.
