随着影像学检查技术的发展,最近发现 一种新的胰腺肿瘤。在1982年,Ohhashi等报告4例具有独特临床病理特征而不同于普通胰腺癌的胰腺癌病例,认为属于一个完全新的临床类型,称为“粘液产生型癌(mucin-producing carcinoma,M-pC)”。从此,临床存在“粘液产生型肿瘤”得到广泛的认可,全世界每年都有新病例报告。这个类型有明显的特征而不同于普通型胰腺癌。现已知的特点有瓦特氏壶腹(Water)乳头增大、开口扩张,通过扩张的开口分泌粘液;主胰管扩张;预后良好。这些临床特点归因于主胰管、侧枝及周围胰管的上皮分泌大量粘液,这些过度分泌
With the development of imaging techniques, a new type of pancreatic tumor has recently been discovered. In 1982, Ohhashi et al. reported on 4 cases of pancreatic cancer with unique clinicopathologic features that were different from common pancreatic cancer and considered it to be a completely new clinical type, known as mucin-producing carcinoma (M-pC). )“. Since then, the clinical existence of ”mucus-producing tumors" has been widely recognized, and new cases are reported every year in the world. This type has distinct characteristics and is different from normal pancreatic cancer. The currently known features are the enlargement of the papillae of the Watert’s ampulla, the expansion of the opening, the secretion of mucus through the dilated opening, the expansion of the main pancreatic duct, and the good prognosis. These clinical features are attributed to the secretion of large amounts of mucus from the epithelium of the main pancreatic duct, collateral ducts, and surrounding pancreatic ducts. These excessive secretions
