A rare case of splenic epidermoid cyst (SEC) of the pancreas discovered in a 32-year-old Japanese female is reported. The lesion, 5 x 6 cm in size including caseous material and serous fluid in the lumen, was discovered by ultrasonography and computed tomography at the tail of the pancreas and was easily removed. Histopathologically, the cystic wall consisted of three components: the inside was lined by mature squamous epithelium with keratinization, the middle layer consisted of splenic pulp with a sinus structure, and the peripheral layer was dense fibrous connective tissue in which some involutional pancreatic ducts and islets were recognized. The literature about SEC of the pancreas is discussed in comparison with other types of epidermoid cyst including lymphoepithelial cyst and dermoid cyst in the pancreas.
报告了一例在一名32岁日本女性中发现的罕见胰腺脾样表皮样囊肿（SEC）病例。该病变大小为5×6厘米，囊腔内含有干酪样物质和浆液，通过超声检查和计算机断层扫描在胰腺尾部发现，易于切除。组织病理学检查显示，囊壁由三个部分组成：内部衬有角化的成熟鳞状上皮，中间层为具有窦状结构的脾髓，外周层为致密的纤维结缔组织，其中可见一些退化的胰管和胰岛。本文结合胰腺其他类型的表皮样囊肿，包括胰腺淋巴上皮囊肿和皮样囊肿，对胰腺SEC的相关文献进行了讨论。
