Low grade endometrial stromal sarcoma (LGESS) is a rare neoplasm that typically arises in the uterine corpus and accounts for less than 1% of uterine sarcomas. Infrequently, extra-uterine LGESS can occur. Histologically, LGESS is characterized by a monotonous population of cells that resemble the proliferative phase of endometrial stroma and in their classic form they exhibit tongue-like growth pattern of infiltration and/or lymphovascular invasion. Infrequently LGESS can demonstrate various morphologic differentiation patterns, including endometrioid-type glands. We report the first fine needle aspiration (FNA) case of a periduodenal mass that was incidentally discovered on Computed Tomography (CT) scan of a 60-year-old female. The cytomorphologic and histologic findings and the immunohistochemical staining were consistent with a LGESS with endometrioid glandular differentiation. We are presenting the correlation between the cytologic, radiologic and pathologic features.
低度子宫内膜间质肉瘤（LGESS）是一种罕见的肿瘤，通常发生在子宫体，占子宫肉瘤的不到 1%。偶尔也会发生子宫外 LGESS。组织学上，LGESS 的特征是类似于子宫内膜基质增生期的单调细胞群，在其经典形式中，它们表现出浸润性和/或脉管侵犯的舌状生长模式。偶尔 LGESS 可以表现出各种形态分化模式，包括子宫内膜型腺体。我们报告了首例经皮细针抽吸（FNA）诊断十二指肠周围肿块的病例，该病例是在对一名 60 岁女性的计算机断层扫描（CT）偶然发现的。细胞学形态、组织学发现和免疫组织化学染色与具有子宫内膜样腺体分化的 LGESS 一致。我们正在展示细胞学、影像学和病理学特征之间的相关性。
