Among duodenal tumors, lymphangioma is relatively infrequent. In this case report, we describe the case of a 65-year-old Japanese man with duodenal lymphangioma diagnosed by esophagogastroduodenoscopy. Endoscopically, the tumor appeared as a soft submucosal tumor with white spots. When the white spots were grasped by biopsy forceps, milky liquid exuded from the tumor. Additionally, observation by a magnifying endoscope with narrow-band imaging revealed elongated microvessels on the surface. We speculated that this feature was formed because the duodenal villi were dilated and the microvessels were stretched due to the retention of chyle. These endoscopic findings are key features in the diagnosis of duodenal lymphangioma.
在十二指肠肿瘤中，淋巴管瘤相对少见。在本病例报告中，我们描述了一名65岁日本男性经食管胃十二指肠镜检查诊断为十二指肠淋巴管瘤的病例。在内镜下，肿瘤表现为带有白色斑点的柔软黏膜下肿瘤。当用活检钳夹住白色斑点时，肿瘤渗出乳状液体。此外，使用窄带成像的放大内镜观察发现肿瘤表面有拉长的微血管。我们推测这种特征的形成是由于乳糜潴留导致十二指肠绒毛扩张和微血管伸展。这些内镜表现是十二指肠淋巴管瘤诊断的关键特征。
