An unusual case of asymptomatic squamous cell carcinoma of the esophagus metastatic to the pancreas, mimicking a rare primary pancreatic neoplasm, is reported. Percutaneous fine needle aspiration (FNA) biopsy of a pancreatic lesion showed squamous cell carcinoma, which in the pancreas is virtually always metastatic in origin. This prompted a search for an occult primary elsewhere, resulting in the discovery of an esophageal neoplasm, which in itself is one of the least likely sources of pancreatic metastases. FNA biopsy was thus a useful and accurate diagnostic tool in establishing the true nature of the pancreatic neoplasm, sparing the patient unnecessary pancreatic surgery, with its attendant morbidity and hospital costs.
本文报告了一例罕见的无症状食管鳞状细胞癌转移至胰腺的病例，该病例酷似一种罕见的原发性胰腺肿瘤。对胰腺病变进行经皮细针穿刺抽吸（FNA）活检显示为鳞状细胞癌，而在胰腺中，鳞状细胞癌几乎均为转移性起源。这促使医生寻找其他隐匿的原发部位，最终发现了食管肿瘤，而食管本身是胰腺转移瘤最不可能的来源之一。因此，FNA活检是确定胰腺肿瘤真实性质的一种有用且准确的诊断工具，避免了患者接受不必要的胰腺手术及其带来的发病率和住院费用。
