Solitary diaphragmatic metastasis from early endometrial cancer is quite rare. We present a case of a 58-year-old woman who had been performed radical surgery for stageⅠA, G1 endometrial cancer 3 years before. The patient was referred to our hospital for chest abnormal shadow. Computed tomography (CT) and Magnetic resonance imaging (MRI) showed a mass in the right diaphragm, without the finding of liver invasion. We performed partial resection of diaphragm through video-assisted thoracoscopic surgery (VATS). After surgery, there were no serious complications and was discharged from the hospital on day 6 from surgery. Nine months later, the patient is alive without recurrence.
