Case description

Histologic examination of the biopsies specimen confirmed the diagnosis of cecal ameboma. Biopsy specimens obtained from the ulcerative lesion in the revealed a number of amebic organisms, trophozoites. The intestinal protozoan parasite, E histolytica, is the causative agent of human amebiasis and the clinical syndrome of amebic dysentery. Transmission is mostly by ingestion of contaminated food or water, but venereal transmission via the fecal-oral route also occurs. Trophozoites are responsible for invasive disease, which sometimes results in dissemination and formation of amebic liver abscesses.
