Blastocystis sp. is a frequent parasite in humans, identified in the laboratory in samples of fecal feces. The case of a 5-year-old patient is presented; he assisted the consultation of Gastroenterology in the Provincial Teaching Pediatric Hospital Eliseo Noel Caamaño in Matanzas, suffering abdominal pain, mash feces, nauseas and vomits for one year, and was treated with ranitidine, omeprazole and domperidone without clinical improvement. A coproparasitological study was carried out in serial fecal feces samples with the presence of Blastocystis hominis. Treatment with metronidazole was indicated without clinical improvement and them, as an alternative, nitazoxanide was indicated. He was evaluated at 15 days without symptoms and with negative serial fecal feces. The ignorance and the little importance that health professionals show towards this infestation are frequent, although more and more frequently it is confirmed the participation of the parasite in clinical manifestations.
