摘要


胰臟淋巴上皮性囊腫是相當罕見之疾病,其發病機轉至今仍未有定論。其病理特徵為囊腫被覆上角質蛋白及成熟之複層扁平上皮,由稠密的淋巴組織所包圍。臨床上,它與其他胰臟的囊性腫瘤在影像學上無法作鑑別診斷。本文提出-65歲女性因上腹疼痛一個月,影像檢查發現胰臟頭部腫瘤並接受手術之經過。並對該疾病之臨床表徵,影像學與實驗室檢查,病理特色及致病機轉作一文獻回顧。

Lymphoepithelial cyst of the pancreas is a rare cystic benign tumor characterized by the presence of a keratinizing, mature stratified squamous epithelium surrounded by dense lymphoid tissue on histologic examination. To the best of our knowledge, this is the first case reported in Taiwan. Review of the literature revealed fewer than 40 previously reported cases in the English literature. We present a case of a 65-year-old female with vague abdominal pain. A 6.5×3 cm pancreatic head tumor was detected by abdominal ultrasonography and magnetic resonance imaging (MRI) study. This patient received laparotomy with total excision of the tumor. The patient has been well and followed-up for two years without recurrence. The clinical behavior; pathogenesis, radiological and pathological features, as well as treatment are discussed. In addition, the differential diagnosis of cystic lesions of the pancreas is also discussed.
