Schistosomal cholecystitis.
A 51-year-old man with schistosomiasis had symptoms of cholecystitis due to Schistosoma mansoni eggs found in all layers of the gallbladder associated with all stages of inflammatory granulomatous reaction. Adult worms were found in a subserosal venule also. Why parasitism of the gallbladder by S mansoni eggs is apparently rare is not known.
