Primary mediastinal leiomyosarcomas are malignant sarcomas with unknown etiology not deriving from the smooth muscle fiber of the esophagus, trachea or main vessels. Very few cases have been reported in the literature and, although they are clinically unspecific, their histology is unique. The case described here is a 66-year-old woman with a leiomyosarcoma localized at the medium and posterior mediastinum, clinically presented as a mediastinal emergency.
原发性纵隔平滑肌肉瘤是一种病因不明的恶性肉瘤，并非来源于食管、气管或主要血管的平滑肌纤维。文献中报道的病例极少，尽管其临床表现缺乏特异性，但其组织学表现独特。本文所述病例为一名66岁女性，其平滑肌肉瘤位于纵隔中后部，临床上表现为纵隔急症。
