A 66-year-old man was diagnosed with a gastric submucosal tumor. Endoscopic ultrasound (EUS) revealed an iso/hypoechoic mass in the third layer. No malignant cells were detected in a histological examination. Yearly follow-up endoscopy and EUS showed the slow growth of the tumor. Endoscopic submucosal dissection (ESD) was performed and a glistening tumor was resected. The lesion showed a multinodular plexiform growth pattern consisting of spindle cells with an abundant fibromyxoid stroma that was rich in small vessels. The tumor was diagnosed as plexiform fibromyxoma (PF) by immunohistochemistry. Although difficulties are associated with reaching a diagnosis preoperatively, chronological changes on EUS may contribute to the diagnosis of PF. ESD may also be useful in the diagnosis and treatment of PF.
一名66岁男性被诊断为胃黏膜下肿瘤。内镜超声（EUS）显示第三层有等回声/低回声肿块。组织学检查未检测到恶性细胞。每年的随访内镜检查和EUS显示肿瘤生长缓慢。进行了内镜黏膜下剥离术（ESD），切除了一个有光泽的肿瘤。病变呈现多结节丛状生长模式，由梭形细胞组成，伴有丰富的富含小血管的纤维黏液样基质。通过免疫组织化学诊断该肿瘤为丛状纤维黏液瘤（PF）。尽管术前诊断存在困难，但EUS上的时间变化可能有助于PF的诊断。ESD在PF的诊断和治疗中也可能有用。
