We report a case of hemangiopericytoma of the soft palate of 60-year-old patient, who noticed a mass of the soft palate and experienced difficulty in speaking. We found a pediculate, hard, elastic mass measuring 38 mm (cross-sectional diameter). Computed tomography (CT) scans and dynamic magnetic resonance imaging (MRI) confirmed irregularly shaped mass and revealed a heterogeneous internal composition, consistent with vascular tumors. We excised the tumor under general anesthesia. Histopathological diagnosis was based on positive immunoreactivity of CD99 and vimentin and weak, positive staining of CD34. Three and half years following tumor excision, there is no recurrence or metastasis.
我们报告一例 60 岁患者的软腭血管外皮细胞瘤,患者发现软腭有一肿块,并伴有言语困难。我们发现一个带蒂的、硬的、有弹性的肿块,大小为 38mm(横径)。计算机断层扫描(CT)和动态磁共振成像(MRI)证实了不规则形状的肿块,并显示出不均匀的内部成分,符合血管肿瘤。我们在全身麻醉下切除了肿瘤。组织病理学诊断基于 CD99 和波形蛋白的阳性免疫反应,以及 CD34 的弱阳性阳性染色。肿瘤切除后 3 年半,无复发或转移。
