A 69-year-old male with chronic lymphocytic leukemia presented with iron deficiency anemia and post-prandial abdominal fullness. Endoscopy showed a large polyp on a stalk, protruding through the pylorus into the duodenum causing intermittent gastric outlet obstruction. While prolapsing gastric antral polyps are usually benign and hyperplastic, inflammatory or regenerative in type, excisional snare polypectomy here led to complete resolution of his symptoms, but showed a malignant polyp.
一名69岁慢性淋巴细胞白血病男性患者,出现缺铁性贫血和餐后腹部饱胀感。内镜检查显示一个带蒂的大息肉,经幽门突入十二指肠,导致间歇性胃出口梗阻。虽然脱垂性胃窦息肉通常为良性,类型上多为增生性、炎性或再生性,但此次圈套切除息肉术后患者症状完全缓解,却发现是恶性息肉。
