Haemangiopericytoma (HPC) is a rare vascular tumor with borderline malignancy, considerable histological variability, and unpredictable clinical and biological behavior. HPC can present a diagnostic challenge because of its indeterminate clinical, radiological, and pathological features. HPC generally presents in adulthood and is equally frequent in both sexes. HPC can arise in any site in the body as a slowly growing and painless mass. The precise cell type origin of HPC is uncertain. One third of HPCs occur in the head and neck areas. Exceptional cases of hemangioblastoma arising outside the head and neck areas have been reported, but little is known about their clinicopathologic and immunohistochemical features. This study reports on a case of a large sacro-anterior HPC in a 65-year-old male.
血管外皮细胞瘤（HPC）是一种罕见的具有交界性恶性肿瘤、显著组织学变异性和不可预测的临床和生物学行为的血管肿瘤。由于其不确定的临床、放射学和病理学特征，HPC 可能会带来诊断上的挑战。HPC 通常发生在成年期，在两性中发病率相当。HPC 可以在身体的任何部位作为一个缓慢生长且无痛的肿块出现。HPC 的精确细胞类型起源尚不确定。三分之一的 HPC 发生在头颈部。也有报道称在头颈部以外部位发生的血管母细胞瘤，但对其临床病理和免疫组织化学特征知之甚少。本研究报告了一例 65 岁男性骶前巨大 HPC。
