title: A case of primary leiomyosarcoma of the chest wall successfully resected under the video-assisted thoracoscopic approach.
abstract: We report a case of a 62-year-old woman with primary leiomyosarcoma of the chest wall which was successfully resected under the video-assisted thoracoscopic approach. The disease was found during the treatment for a malignant melanoma of the left heel. On the preoperative CT images, the lesion was suspected to be a metastasis of the malignant melanoma. The thoracoscopic surgery revealed that the tumor originated from the parietal pleura, and it was resected with a 5-mm margin of normal pleura. Histopathologically, the tumor was diagnosed as low-grade leiomyosarcoma. Since no residual tumor cells were proven in the resected margins histologically, further resection was not performed. At present, she is alive and well with no sign of recurrence of leiomyosarcoma two years and one month after operation. Thoracoscopic surgery is worth trying for accurate diagnosis of and effective treatment for a chest lesion without apparent invasion of the chest wall on the preoperative CT images.
