A 42-year-old woman was referred to our hospital with chest pain. Chest CT showed left pneumothorax and bilateral pulmonary cysts. We performed lung cyst resection using video assisted thoracoscopic surgery. Pathological diagnosis revealed lung metastasis of Epithelioid Sarcoma (ES). During the four months following the development of left pneumothorax, right lung cysts gradually increased. We performed a right lower lobectomy and a further pathological diagnosis of lung metastasis of ES was made. Five months after the right lower lobectomy, the patient felt a swelling in her left calf. A soft tissue tumor was present in the soleus muscle. We took a pathological biopsy from the soft tissue tumor, and its pathological diagnosis was ES. Twenty one months following the development of pneumothorax, the patient died due to disease progression.
