Blastocystis hominis (B. hominis) is an anaerobic protozoan parasite, which lives in human and\udanimal ’s intestines. It is commonly found in the tropical area. The parasite is low pathogen and its\udinfection causes gastrointestinal disease with diarrhea symptom as reported from many studies.\udB. hominis is rarely seen in tissue section. The clinical diagnoses are usually confirmed with the\udmicroscopic examination of the stool, which can directly detect the parasite through trichrom\udstain and Kinyoun acid fast technique. We reported a case of 52 years old man with abdominal\udpain and suspected as perforated appendicitis and tumor of appendix as the differential diagnosis.\udThe macroscopic features of the appendix mass were 7 cm in length and 1.5-2.5 cm in diameter.\udThe cut section showed a widening of the appendix lumen, and the distal part filled with a\udgelatinous mass. The microscopic examination with HE stain showed the infiltration of PMN\udinflammatory cells in the muscle layer of the appendix and foci of a number of round structures\udin the sub mucosal layer known as B. hominis. Some authors reported results from the endoscopy\udand biopsy examinations that B. hominis does not infiltrate in the intestinal mucosa; nevertheless,\udin this case we found the infiltration of the parasite towards the mucosal and sub mucosal layers\udof the appendix
