Actinomycosis is a slowly progressive, chronic infectious disease. It is caused by the genus Actinomyces, which are gram-positive anaerobic bacteria. It presents as a mass-like lesion, composed of bacterial nidus and characteristic granulomatous inflammatory fibrosis. As such, it has frequently been mistaken for a malignancy. Surgical resection is a common procedure in these patients prior to a definite diagnosis. Although actinomycosis can occur in a variety of regions, including oral-cervicofacial, thoracic, and abdominopelvic cavities, the involvement of the pancreas is very rare. We report a case of a 44-year-old male with a symptomatic actinomycosis caused by a mass in the tail of the pancreas. The diagnosis was made using an endoscopic ultrasound-guided fine needle aspiration biopsy without surgical resection. After the treatment with antibiotics, the pancreatic mass was confirmed to be resolved on the follow-up computed tomography.
放线菌病是一种进展缓慢的慢性感染性疾病。它由放线菌属引起，放线菌属是革兰氏阳性厌氧菌。其表现为肿块样病变，由细菌病灶和特征性肉芽肿性炎性纤维化组成。因此，它常被误诊为恶性肿瘤。在明确诊断之前，手术切除是这些患者的常见治疗手段。尽管放线菌病可发生于包括口腔-颈面部、胸部和腹腔盆腔等多个部位，但胰腺受累非常罕见。我们报告一例44岁男性患者，其胰腺尾部肿块导致了有症状的放线菌病。通过内镜超声引导下细针穿刺活检确诊，未进行手术切除。抗生素治疗后，随访计算机断层扫描证实胰腺肿块已消退。
