Olfactory ensheathing cells (OECs) are found in the olfactory bulb and olfactory nasal mucosa. They resemble Schwann cells on light and electron microscopy, however, immunohistochemical staining can distinguish between the two. There are less than 30 cases of olfactory groove schwannomas reported in the literature while there is only one reported case of OEC tumor. We report an OEC tumor in a 42-year-old male and discuss the pathology and origin of this rare tumor.
嗅鞘细胞（OECs）存在于嗅球和嗅鼻黏膜中。在光学显微镜和电子显微镜下，它们类似于施万细胞，然而，免疫组织化学染色可以区分这两者。文献中报道的嗅沟神经鞘瘤病例少于30例，而嗅鞘细胞瘤仅报道过1例。我们报告了1例42岁男性的嗅鞘细胞瘤，并讨论了这种罕见肿瘤的病理学及起源。
