Splenic abscess is not a common condition and actinomyces as a cause is very rarely reported. We report a case of actinomycosis of spleen in a 12 year-old boy, with a few days history of abdominal pain and fever. Past medical history was not significant. Due to sever abdominal pain and tenderness condition laparatomy was done that a small perforated area was seen on hilum of spleen, so splenectomy was done. In the histological sections typical actinomyces ball surrounded by many inflammatory cells are seen. The patient received penicillin and discharged in a good condition. This has not been previously reported in the pediatric literature.
