Haemangiopericytoma (HPC) is a rare vascular tumor comprising 1% of all vascular neoplasms and was first described by Stout and Murray in 1942. They are highly vascularized tumours located in any part of the body. Malignant HPCs represent <1% of all vascular tumours and around 5% of all sarcomatous tumours. The majority has a relatively indolent behaviour with presenting symptoms being vague for several months and not specific. Surgical excision is the mainstay of treatment. We present the case of a 65-year old male with HPC of left infraclavicular region with no associated lymphadenopathy. Surgical management included en bloc excision. The patient did not require any adjuvant therapy and showed no signs of recurrence at 1-year follow up. KEY WORDS: Haemangiopericytoma, Extracranial, Surgical excision, Vascular tumor.
血管外皮细胞瘤（HPC）是一种罕见的血管肿瘤，占所有血管肿瘤的 1%，于 1942 年由 Stout 和 Murray 首次描述。它们是位于身体任何部位的高度血管化肿瘤。恶性 HPC 占所有血管肿瘤的<1%，约占所有肉瘤样肿瘤的 5%。大多数具有相对惰性的行为，表现出数月的模糊症状，且不具有特异性。手术切除是主要的治疗方法。我们报告了一例左侧锁骨下区域 HPC 的病例，无相关淋巴结病。手术治疗包括整块切除。该患者不需要任何辅助治疗，在 1 年的随访中没有复发迹象。
