Abstract

Actinomycosis is a rare chronic infectious disease. The most common form is cervicofacial infection. Hepatic involvement constitutes 5% of all actinomycosis infections. Approximately 15% of patients with abdominal actinomycosis is accompanied by liver lesions. Liver involvement is believed to occur as a secondary to another infected focus in the abdomen. However, in some cases, the infection’s primer focus can not be detected and are classified as primary or isolated hepatic actinomycosis. Generally they are in the form of a single, sensitive, firm, and fixed abscess. Sometimes it may be mistaken as tumor. Tissue specimens for microscopic examination are necessary for diagnosis.
