METHODS: A 16-years old female presented a painless, semi-solid, mobile lump on the upper lip measuring of approximately 1.5 × 3 cm that had similar color with the surrounding tissue. The lump appeared 7 years ago.
UNASSIGNED: Excision of the capsule and margins of the tumor. Histopathological examination showed a unique feature of Schwannoma, the Verocay bodies. Subsequent immunohistochemical examination of S100 protein showed a classic type of Schwannoma.
CONCLUSIONS: Upper lip schwannoma is a very rare tumor, and this type of tumor cannot be distinguished from other benign soft tissue tumors based on clinical findings. Immunohistochemical results are in accordance with the Histopathological results for the final diagnosis of Schwannoma. Schwannoma can be used as a differential diagnosis in cases of lumps on the lips with sessile, similar color like surrounding tissue, painless, and movable features.
方法:一名16岁女性表现出无痛,半固体,上唇上大约1.5×3厘米的移动肿块,与周围组织颜色相似。这个肿块出现在7年前。
■切除肿瘤的囊和边缘。组织病理学检查显示神经鞘瘤的独特特征,Verocay的尸体.随后对S100蛋白的免疫组织化学检查显示典型的神经鞘瘤类型。
结论:上唇神经鞘瘤是一种非常罕见的肿瘤,根据临床发现,这种类型的肿瘤不能与其他良性软组织肿瘤区分开来。免疫组织化学结果与最终诊断神经鞘瘤的组织病理学结果一致。神经鞘瘤可用于嘴唇上有无柄肿块的鉴别诊断,与周围组织的颜色相似,无痛,和可移动的功能。
