Schwannomas are considered benign soft tissue tumors that originate from Schwann cells. Oral Schwannomas are rare and account for only 1% of all Schwannomas. Cellularschwannoma (CS) is a rare histological variant of schwannoma, characterized by high cellularity and cellular atypia. We present a case of localized growth of palatal mucosa that imitated the features of malignant peripheral nerve sheath tumor (MPNST) on histopathological examination; it was differentiated from MPNST by the correlation of clinical, histopathological, and immunohistochemical features.
神经鞘瘤被认为是起源于施万细胞的良性软组织肿瘤。口腔神经鞘瘤较为罕见，仅占所有神经鞘瘤的1%。细胞性神经鞘瘤（CS）是神经鞘瘤一种罕见的组织学变异型，其特征为细胞密度高和细胞异型性。我们报告一例腭黏膜局限性生长病例，该病例在组织病理学检查中表现出恶性外周神经鞘膜瘤（MPNST）的特征；通过临床、组织病理学和免疫组化特征的相关性，将其与MPNST区分开来。
