Abstract

Endolymphatic sac tumors are uncommon, slow growing, and locally aggressive neoplasms that arise within the endolymphatic sac, most commonly the intraosseous portion located in the temporal bone. There are only three previous cytology reports, and no prior FNAs have been reported. We present a case of a metastatic sporadic endolymphatic sac tumor, a phenomenon that has yet to be described on FNA and has only been previously reported once in cerebrospinal fluid cytology. We described the cytologic features on fine needle aspiration cytology and correlated the cytologic findings with the follow-up surgical resection of the metastatic focus.

转移性内淋巴囊肿瘤的细针穿刺细胞学分析1例

内淋巴囊肿瘤不常见，生长缓慢，局部侵袭性肿瘤发生于内淋巴囊内，最常见的是位于颞骨的骨内部分。既往仅有3例细胞学报道，未见FNAs报道。我们报告一例转移性散发性内淋巴囊肿瘤，这种现象尚未在FNA上描述，并且以前仅在脑脊液细胞学中报道过一次。我们描述了细针穿刺细胞学的特征，并将细胞学结果与转移灶的后续手术切除联系起来。
