[Parasitological examinations of the hydatoid cysts of liver].
Liver cysts taken from 9 patients, operated on in the Medical Academy Clinic in 2000, have been examined. Cyst layers, their thickness and content have been analysed. We have searched for the cestoid scolexes and rostellar hooks. In 6 patients Echinococcus granulosus larvae have been found. In 4 cases there have been protoscolexes discovered, however with some signs of degeneration of the larva. In one case dead larva has been diagnosed on the basis of the presence of single hooks and in one patient one larva alive with unchanged structures has been revealed. Profound parasitological examination is a good supplement to the examination of the histopathological slides, especially in the case of degenerating larvae, when the tissues of the parasite lose their contact with the connective tissue layer of the host. Separated layer fragments, as well as protoscolexes and rostellar hooks need not be exposed to histological cutting.
