Cystic Hydatid Disease due to infection with the Echinococcus has a worldwide distribution. Immunodiagnosis, although sensitive and specific is not always reliable. The cytologic features in liver aspirate of a 54 year old male and in transrectal aspirate of a 43 year old male were the presence of scolices and characteristic refractile hooklets. Retractile laminated membrane was observed in the histology sample.
Although aspiration of echinococcal cyst is usually discouraged due to possible anaphylactic reaction, the two cases presented here were aspirated because they were clinically thought to be of neoplastic origin. A Casoni's test in one case was negative for hydatidosis. A negative Casoni's test does not exclude the presence of disease.
