A 34-year-old man with poorly controlled acquired immune deficiency syndrome underwent excision of a left arm mass. The histopathologic workup identified the features of an Epstein-Barr virus-associated smooth muscle tumor (EBV-SMT). The patient was readmitted 5 months later for vomiting and found to have liver metastases that were confirmed to be EBV-SMT. Six months after discharge, there was no recurrence of the arm mass or increase in the size of the liver metastases.
Most commonly found in immunocompromised patients, EBV-SMTs are rare tumors that can be mistaken for a leiomyosarcoma.
一名 34 岁患有艾滋病且控制不佳的男子接受了左手臂肿块切除术。组织病理学检查发现了与 EBV 相关的平滑肌肿瘤(EBV-SMT)的特征。患者 5 个月后因呕吐再次入院,发现肝转移,经证实为 EBV-SMT。出院后 6 个月,手臂肿块无复发,肝转移灶无增大。
EBV-SMT 常见于免疫功能低下的患者,是一种罕见的肿瘤,容易误诊为平滑肌肉瘤。
