目的：研究多形性低度恶性腺癌（PLGA）的组织病理学和免疫组织化学特点，并与腺样囊性癌（ACC）进行比较。方法；采用组织病理学与免疫组织化学方法，对8例PLGA与10例ACC进行分析。结果；PLAC的特点是组织学上具有细胞形态的一致性与组织结构的多形性；免疫级化染色呈阳性或部分阳性反应，与ACC没有明显差异。结论：光镜下组织结构的多形性是鉴别PLGA与ACC的重要指征；免疫组化对二者的区分意义不大；均起源于闰管储备细胞是导致二者相似性的根本原因。
Objective: To study the histopathological and immunohistochemical features of polymorphic low-grade adenocarcinoma (PLGA) and compare it with adenoid cystic carcinoma (ACC). Methods: 8 cases of PLGA and 10 cases of ACC were analyzed by histopathology and immunohistochemistry. Results; PLAC is characterized by histological consistency of the cell morphology and polymorphism of the tissue structure; immunohistochemical staining positive or partial positive reaction, and no significant difference with ACC. Conclusion: The pleomorphism of the tissue structure under light microscope is an important indicator for identifying PLGA and ACC; immunohistochemistry has little significance for distinguishing the two; both originating from the reserve cells of the fistula are the root causes of the similarity between the two.
