Aneurysmal bone cysts are an uncommon form of benign primary bone tumors; affection of the hand is very rare.
A rigorous review of the literature showed that this type of tumor has not previously been described in the pisiform. In this article, we report the occurrence of an aneurysmal bone tumor in the pisiform of the left hand of a 19-year-old male.
This tumor was successfully treated through surgical excision with an uneventful recovery. We describe the process behind the diagnosis of the lesion and the subsequent treatment in an attempt to highlight the rare but possible occurrence of aneurysmal bone cysts in the pisiform.
Appropriate treatment of aneurysmal bone cysts in this location is required, due to the anatomical nature of the pisiform itself with the risks of pathologic fracture and ulnar nerve compression.
动脉瘤样骨囊肿是一种罕见的原发性良性骨肿瘤；手部受累非常罕见。
对文献的严格回顾表明，此前尚未有这种类型的肿瘤在豌豆骨中的描述。在本文中，我们报告了一名19岁男性左手豌豆骨中出现动脉瘤样骨肿瘤的病例。
该肿瘤通过手术切除成功治疗，恢复顺利。我们描述了病变诊断及后续治疗过程，旨在强调豌豆骨中动脉瘤样骨囊肿虽罕见但有可能发生。
鉴于豌豆骨本身的解剖特性以及存在病理性骨折和尺神经受压的风险，对此部位的动脉瘤样骨囊肿需要进行适当治疗。
