[Hepatic polycystic hydatidosis. Clinical and histopathologic report of the second native case of echinococcosis in the Republic of Panama].

The second autochthonous case of hepatic hydatidosos by Echinococcus vogelli is reported for the Republic of Panama. The patient was a 8 year old female living in the Province of Colon (Maria Chiquita). She claimed never to have traveled outside panamanian territory. The multichambered cysts with fertile, numerous protoscolices were identified from biopsied material obtained after exploratory laparotomy at Manuel Amador Hospital in Colon (Republic of Panama). The cyst appeared multiloculated mostly affecting the left lobe of the liver, beside a cystic lesion on the right lobe. The large rostellar hooks, in a count of 100 protoscolices, had a total length of handles and blades which average 41 microns in diameter, which coincide with those of E. vogeli, the most prevalent hydatid disease in man in South and Central America.
