[Acute, non-lithiasic, amebic cholecystitis].

The estimated percentage of non calculous cholecystitis is 2-14%. In most cases it is difficult to identify the cause and in very few cases it is possible to establish the etiology. Few cases are secondary to bacterial infections and the cause is very rarely a parasitic infection. We present a case of acute cholecystitis secondary to Entamoeba histolytica infection; the frequency, etiopathogenic mechanism and treatment are discussed.
