Schistosomiasis is a trematodes infection more prevalent in tropical and subtropical areas such as Yemen. Giant colonic polyp manifestations of intestinal bilharziasis are uncommon, difficult to differentiate from other colonic polyps, and can mimic cancer.
A 10-year-old child presented with chronic abdominal pain that started ten months ago. The patient had a family history of lymphoma in his brother. The computed tomography scan showed a sigmoid luminal mass measuring 10×3 cm with significant lumen narrowing and diffuse circumferential wall thickening of the sigmoid colon, hepatomegaly, and multiple perilesional, para-hepatic, and pulmonary lymph nodes enlargements. The mass was morphologically mimicked cancer and proved to be of bilharzial etiology () after surgical excision.
Even though the bilharzial colonic polyps are rare, it is challenging to differentiate them from other malignant colonic polyps. Clinicians should have a high suspicion regarding its manifestations to avoid unnecessary surgical interventions, especially in an endemic area, even in patients with a strong family history of cancer.
血吸虫病是一种由吸虫引起的感染，在也门等热带和亚热带地区更为普遍。肠道血吸虫病的巨大结肠息肉表现并不常见，难以与其他结肠息肉区分开来，且可能类似癌症。
一名10岁儿童出现了始于10个月前的慢性腹痛。该患者的哥哥有淋巴瘤家族史。计算机断层扫描显示乙状结肠腔内有一个大小为10×3厘米的肿块，乙状结肠管腔明显狭窄，肠壁弥漫性环形增厚，肝脏肿大，以及多个病灶周围、肝旁和肺门淋巴结肿大。该肿块在形态上类似癌症，手术切除后证实为血吸虫病因。
尽管血吸虫性结肠息肉很少见，但将它们与其他恶性结肠息肉区分开来具有挑战性。临床医生应对其表现高度怀疑，以避免不必要的手术干预，尤其是在流行地区，即使是有癌症家族史的患者。
