The present case highlig hts the aspiration cytology findings in a case of Echinococcus oligart hrus injection, a rave variant of the Echinococcus species affecting h umans. To the best of our knowledge, this is the first case report on the cytology off oligarthrus in English.CASE: A submandibular swelling developed in a 14-year-old male. A mistaken diagnosis of Cysticercus cellulosae teas made on the first aspirate and of a hydatid cyst (Echi nococcus granulosus) on the second aspirate.
