The present study was conducted as an attempt to chemically treat secondary hydatid cyst disease in the Albino mouse Mus musculus strain Balb/c. Oxfendazole (OFZ) was used at a concentration of 30 mg/kg, and the histopathological changes in the liver and spleen were examined. The efficiency of the drug was observed compared to the positive untreated control group. However, some histopathological changes were noticed in liver and spleen of the OFZ-treated mice.
