Sclerosing angiomatoid nodular transformation (SANT) of the spleen is a specific, tumor-forming, non-neoplastic, vascular lesion with few reported cases worldwide. Herein, we describe the case of a patient who underwent laparoscopic splenectomy for SANT. A 47-year-old woman underwent upper gastrointestinal endoscopy for suspected gastric submucosal tumor. Contrast-enhanced abdominal computed tomography revealed the presence of a gradually enhancing lesion in the splenic hilum. Although we suspected splenic fibrotic hamartoma, malignancy could not be ruled out. Therefore, the patient underwent laparoscopic splenectomy, resulting in the histopathological diagnosis of SANT. Although SANT is a benign tumor, it may be difficult to obtain definitive diagnosis using preoperative imaging alone. Because the long-term natural history of SANT is unknown, we believe that splenectomy could be an appropriate technique for the diagnosis and treatment of SANT.
脾脏硬化性血管瘤样结节性转化（SANT）是一种特殊的、形成肿瘤的、非肿瘤性血管病变，全球报道的病例较少。在此，我们描述一例因SANT接受腹腔镜脾切除术的患者。一名47岁女性因疑似胃黏膜下肿瘤接受上消化道内镜检查。腹部增强计算机断层扫描显示脾门处有一个逐渐强化的病变。尽管我们怀疑是脾纤维性错构瘤，但不能排除恶性肿瘤。因此，患者接受了腹腔镜脾切除术，组织病理学诊断为SANT。虽然SANT是一种良性肿瘤，但仅通过术前影像学检查可能难以获得明确诊断。由于SANT的长期自然病程尚不清楚，我们认为脾切除术可能是诊断和治疗SANT的合适技术。
