Solitary fibrous tumor of the lacrimal gland mimicking pleomorphic adenoma

ABSTRACT Solitary fibrous tumor (SFT) is a rare mesenchymal spindle-cell neoplasm commonly found in the pleura; it is rare in the orbit and extremely rare in the lacrimal gland. We herein report a case of SFT of the lacrimal gland that mimicked a pleo morphic adenoma. We discuss the clinical, radiological, histopathological, and immunohistochemical findings that provided insight and rationale to accurately diagnose this case.

摘要 孤立性纤维性肿瘤（SFT）是一种少见的间叶源性梭形细胞肿瘤，好发于胸膜；该肿瘤在眼眶中较为少见，在泪腺中则极为罕见。本文报告1例发生于泪腺、酷似多形性腺瘤的孤立性纤维性肿瘤病例，并对该病例的临床、影像学、组织病理学及免疫组织化学特征进行探讨，以期为精准诊断该病例提供思路与理论依据。
