Thoracoscopic left lower lobectomy with lymph node dissection for lung cancer was performed in a 76-year-old man. Sixteen months after surgery, CT revealed a pleural tumor measuring 38â€‰mm at the surgical port wound. Thoracoscopic tumorectomy was conducted. The pathological diagnosis was desmoid tumor. As the margins of the resected specimen were positive, radiotherapy was performed. During the 16-month follow-up period, there has been no relapse. Pleural desmoid tumors must be differentiated from port-site relapse.
