Cytologic detection of parasitic disorders.

Parasitic diseases are common in developing countries; yet they are infrequently diagnosed in cytologic material. Six cases are described where routine cytologic examination identified the parasites and suggested the diagnosis. There were three cases of Entamoeba histolytica infection of the female genital tract and one each of hydatid cyst of the brain, Strongyloides stercoralis infection of the lung and filarial infection of the urinary bladder. To our knowledge, cytologic diagnosis of hydatid cyst of the brain and filarial infection of the urinary bladder has not been previously reported.
