Amebiasis and its complications continue to be a public health problem in our developing countries. The differential diagnosis of masses located in the right colon, cecum and ascending colon must include the possibility of amebomas, the diagnosis of which requires an early colonoscopy, histopathologic studies and blood tests to check for the presence of intestinal amebiasis. These measures can lead to early diagnosis and to suitable treatment. 2. Huston CD. Intestinal Protozoa.

La amebiasis continua siendo un problema de salud pública en nuestros países en vía de desarrollo y sus complicaciones se presentan aún en nuestros días; el diagnóstico de masas localizadas en el colon derecho, ciego y colon ascendente incluyen como diagnóstico diferencial el ameboma y debe tenerse presente para la realización de estudios colonoscópicos, histopatológicos previos, así como la realización de serologías para estudio de amaebiasis intestinal, que lleven a un diagnóstico previo y a su tratamiento adecuado.
