Background: Primary hepatic actinomycosis is a rare infection that can be clinically confused with hepatic pyogenic abscesses or neoproliferative processes. Only a few cases of primary hepatic actinomycosis in children have been reported in the English literature.
Case summary: We describe a pediatric patient with primary hepatic actinomycosis that involved the base of the right lung and anterior abdominal wall and skin. The patient was diagnosed via histological examination of spontaneously drained material. The patient was successfully treated with an exploratory laparotomy and right posterior segmentectomy of the liver, combined with antibiotic treatment. Following surgery, the patient remains in excellent condition, without evidence of recurrence at the time of drafting this report. To summarize the clinical manifestations, diagnosis, treatment, and outcomes of primary hepatic actinomycosis, 18 case reports in English were reviewed.
Conclusion: We conclude that actinomycosis clinically features a chronic onset, nonspecific symptoms, and a primarily histologic diagnosis. Prolonged antibiotic treatment combined with invasive intervention provides a good prognosis.
