良性淋巴管内皮瘤是一种罕见的血管性肿瘤，其组织病理学表现类似于低度恶性血管肉瘤或卡波西肉瘤的斑片期。我们报告的情况下，一个49岁的男子与一个良性淋巴管内皮瘤的右大腿上的血管胎记演变后，创伤。由于持续的疼痛和缓慢但进行性增长的病变，我们决定切除肿瘤。需要三个阶段的手术才能获得阴性切缘。我们回顾了迄今为止的BL报告，特别关注那些创伤后发展和那些先前存在的血管病变，并阐述了与低度恶性血管肉瘤的组织病理学鉴别诊断。
Benign lymphangioendothelioma (BL) is a rare vascular neoplasm that can histopathologically mimic a low-grade angiosarcoma or the patch stage of Kaposi sarcoma. We report on the case of a 49-year-old man with a benign lymphangioendothelioma on the right thigh that evolved on a vascular birthmark after a trauma. Because of constant pain and the slow but progressive growth of the lesion, we decided to excise the tumor. Three stages of surgery were needed to obtain negative margins. We review the reports of BL to date, with special attention to those that developed after trauma and those that had a preexistent vascular lesion, and expound on the histopathologic differential diagnosis with low-grade angiosarcoma.
