Colitis caused by Entamoeba histolytica (EH) is prevalent in developing countries. Clinical presentation ranges from mild diarrhoea episodes to dysentery and liver abscess. Ameboma, a complication caused by EH invasion of the intestinal wall, is a rare presentation of amebiasis, occurring approximately in 1.5% of cases. Because of its insidious and variable clinical presentation only few cases are diagnosed previous to surgical intervention. We report a 52 years old Mexican-mestizo female, presenting with a pain-less right lower quadrant abdominal mass and diagnosed of cecal ameboma prior to surgery by colonoscopy and histopathologic examination. The present case highlights the importance of early diagnosis and medical therapy with antiparasitic drugs in order to avoid complications that could lead these patients to unnecessary surgical management.
溶组织内阿米巴（EH）引起的结肠炎在发展中国家很常见。临床表现从轻度腹泻发作到痢疾和肝脓肿不等。阿米巴瘤是由EH侵袭肠壁引起的一种并发症，是阿米巴病的一种罕见表现，约1.5%的病例会出现。由于其隐匿且多变的临床表现，只有少数病例在手术干预前被诊断出来。我们报告了一名52岁的墨西哥-梅斯蒂索女性，她右下腹有一个无痛性肿块，术前通过结肠镜检查和组织病理学检查被诊断为盲肠阿米巴瘤。本病例强调了早期诊断和使用抗寄生虫药物进行药物治疗的重要性，以避免可能导致这些患者接受不必要手术治疗的并发症。
