Core Tip

Core Tip: Amebic liver abscesses are the most commonly encountered extraintestinal manifestation of human invasive amebiasis, which results from Entamoeba histolytica. It breaches the host’s innate defenses and invades the intestinal mucosa. Trophozoites enter the circulatory system and are filtered in the liver and produce abscesses. The diagnostics primarily aim to use PCR or enzyme-linked immunosorbent assay to detect Entamoeba histolytica. Medical treatment of amebic liver abscesses is possible using an amebicidal drug and a luminal cysticidal agent. Prognoses are generally good. Elucidating the detailed pathogenesis and establishing which diagnostic methods are most efficacious will necessitate further analyses of similar clinical cases.
