Non-Hodgkin's lymphoma is a common type of cancer, whose most common site of extranodal involvement is the gastrointestinal tract. However, primary presentation in the pancreas remains uncommon. Among cases with pancreatic involvement, the disease is often found in the head and rarely in the tail. Here, we present a case of a 56-year-old male patient with acute epigastric pain, early satiety, and abdominal distention. CT imaging showed a mass of the pancreatic tail with surrounding lymphadenopathy, concerning lymphoma. Endoscopic ultrasound-guided fine needle aspiration (EUS-guided FNA) diagnosed mature B-cell lymphoma, meeting novel diagnostic criteria for the rare diagnosis of primary pancreatic lymphoma (PPL).
非霍奇金淋巴瘤是一种常见的癌症类型，其最常见的结外受累部位是胃肠道。然而，原发性胰腺表现仍然不常见。在胰腺受累的病例中，疾病常发生在胰头，很少发生在胰尾。在此，我们报告一例56岁男性患者，有急性上腹部疼痛、早饱感和腹胀。CT成像显示胰尾有肿块并伴有周围淋巴结肿大，怀疑为淋巴瘤。内镜超声引导下细针穿刺活检（EUS引导下FNA）诊断为成熟B细胞淋巴瘤，符合原发性胰腺淋巴瘤（PPL）这一罕见诊断的新诊断标准。
