We report a case of 36-year-old woman with myasthenia gravis (MG) combined with mediastinal leiomyosarcoma (LMS) and Stevens-Johnson syndrome (SJS). She was admitted to ICU with the symptoms of acute onset headache, diplopia, ptosis, dysphagia, general weakness, and respiratory difficulty for several days. Physical examination revealed tachypnea, decreased breath sounds and dullness to percussion in right lower chest. Neurologic examination showed ptosis, diplopia, decreased gag reflexes, and generalized proximal weakness. Laboratory studies revealed increased serum acetylcholine receptor antibodies and positive Tensilon test. Chest CT showed a huge mass in the right middle mediastium but no evidence of thymic enlargement. Mediastinal LMS was diagnosed by ultrasound-guided needle biopsy. The myasthenic symptoms were fluctuated in spite og intravenous immunoglobulin, plasmapheresis, and corticosteroid. During therapy, SJS developed. She died 4 months after the onset of the myasthenic symptoms despite the chemotherapy for LMS.

Leiomyosarcoma of the mediastinum and primary leiomyosarcoma of the spine are exceedingly rare. In most cases, spinal leiomyosarcoma is metastatic. In this report, we describe the case of a 58-year-old man who presented with a large leiomyosarcoma of the posterior mediastinum that extended into the adjacent spinal canal. The tumor was completely resected from the mediastinum, but only subtotally removed from the spinal canal because the spinal mass had tightly invaded the spinal cord. Because the patient's postoperative condition was poor, no adjuvant radiotherapy or chemotherapy was administered. He expired 3 months after the surgery due to relapse; the spinal and mediastinal tumor remained at the preoperative size.

종격동의 원발성 평활근육종은 극히 드문 종양으로 대혈관의 평활근세포나 내장쪽 종격동에 있는 중간엽세포에서 발생한다. 문헌보고에 따르면 종양의 완전절제 가능여부가 예후를 결정짓는 가장 중요한 요소이다. 그러나 30~64%의 재발율을 보이고 있으며 완전절제 후 보조요법의 역할에 대해서는 자료가 부족한 실정이다. 저자들은 2년 전 좌측 개흉술로 절제되어 양성종양으로 오진된 종격동 평활근육종의 재발을 치험하여 보고하는 바이다.
