Abstract

A 58-year-old woman with an elevated lesion in the stomach was referred to our hospital. Gastroscopy showed a lobulated mass resembling a submucosal tumor. The tumor showed early enhancement on computed tomography. Endoscopic ultrasound showed a lobulated tumor with distinct borders, no attenuated posterior echoes, and high internal echoes. Fine needle aspiration biopsy pathologically showed normal gastric mucosa and spindle cells growing sparsely with SMA positivity and DOG1/S100 negativities, suggesting an inflammatory fibroid polyp. The patient, therefore, underwent laparoscopy endoscopy cooperative surgery to the gastric lesion. Postoperative pathological study showed downward mucosal proliferation into the submucosal layer in a lobulated manner with hyperplasia of the crypt epithelium. Some part of the lesion was located under the normal orthotopic gastric mucosa. These pathologic findings led us to the diagnosis of gastric hamartomatous inverted polyp (GHIP). In conclusion, endoscopy specialists should note that fibrous component-rich tumors have low internal echoes and attenuated posterior echoes, whereas GHIPs have high internal echoes and no attenuated posterior echoes.

胃火腿状倒置息肉具有高内部回声：病例报告

一名 58 岁女性因胃部隆起病变被转诊至我院。胃镜检查显示其胃部有一个类似粘膜下肿瘤的分叶状肿块。计算机断层扫描显示肿瘤早期强化。内镜超声显示肿瘤呈分叶状，边界清晰，后方无衰减回声，内部回声较高。细针穿刺活检病理显示胃黏膜正常，纺锤形细胞稀疏生长，SMA 阳性，DOG1/S100 阴性，提示为炎性纤维瘤息肉。因此，患者接受了腹腔镜内镜合作手术治疗胃部病变。术后病理检查显示，粘膜向下增生至粘膜下层，呈分叶状，隐窝上皮增生。部分病变位于正常的正位胃黏膜下。这些病理结果使我们确诊为胃癌变性倒置息肉（GHIP）。总之，内镜专家应该注意到，富含纤维成分的肿瘤内部回声低，后方回声衰减，而GHIP内部回声高，后方回声不衰减。
