Abstract: This paper reports the histologic changes in the proliferation and growth of two echinococcus types in 25 patients, 15 with liver or lung cystic echinococcosis and 10 with liver alveolar echinococcosis. The results indicated that these two echinococcus types shared two modes of proliferation including exogenous and endogenous budding. In cystic echinococcus type, endogenous budding showed localized hyperplasia of the germinal membrane, the formation of the brood capsule, and the development of the protoscolices. Exogenous budding appeared chiefly in the migratory process of the protoscolices from the germinal membrane to the outside of the exocyst passing through the laminated layer and the fibro-exocystic wall (Figs. 1-4). In alveolar echinococcus type, endogenous budding was characterized by the propagation of the alveolar wall towards the intra-alveolar cavity with the formation of septum. Exogenous budding showed the alveolar wall propagated towards the exterior to produce daughter and grand-daughter alveoli (Figs. 5-7).
