Abstract: Objective To investigate the clinicopathological features of hepatic alveolar echinococcosis. Methods The clinical, pathological, and imaging data of one case of hepatic alveolar echinococcosis were retrospectively analyzed. HE （hematoxylin-eosin） staining slides were observed for surgical resection, and the pathological tissue morphological characteristics were analyzed, and relevant literature was reviewed. Results The Gross examination showed cystic mass in the liver. Histologically, the liver tissue was purulent, and large necrosis and granuloma formation were seen, some vesicular larvae vesicles of different sizes were seen in the necrotic tissue, and the vesicular larvae vesicles were only seen in the corneal cortex, which showed that there was no structure in the red staining uniform, and no germinal layer was seen. Conclusion Hepatic alveolar echinococcosis is rare in low-incidence areas, and most of the lesions are atypical when erythrotic vesicle-like structures can be seen in the background of hepatic necrotizing granulomatous inflammation, is necessary to be vigilant against the possibility of hepatic alveolar echinococcosis in combination with epidemiological history, imaging, and laboratory examination results, to avoid missed diagnosis and misdiagnosis.
