Echinococcus multilocularis - Alveolar echinococcosis - liver (HES stain)

France, Piarroux Renaud

Exceptional feature of human alveolar echinococcosis. The laminar layer is coated by the germinative layer, which protoscoleces bud off from. Host’s immunological reaction was unable to result in a layer restricting the growth of the parasite.
