[A Case of Mediastinal Lymph Node Recurrence after Endoscopic Submucosal Dissection of Esophageal Cancer].

We report a case of mediastinal lymph node recurrence of esophageal cancer after endoscopic submucosal dissection (ESD). We first administered chemotherapy and then performed esophagectomy. A 78-year-old man underwent ESD for early esophageal cancer at a different hospital in January 2015. H e was diagnosed pathologically with scc, pSM1, pHM1, pVM0, ly0, v0. Additional treatment was not administered because of his age. In June 2017, chest enhanced CT showed swollen mediastinal lymph nodes. This was diagnosed as a recurrence of esophageal cancer, and he presented at our hospital. We first performed chemotherapy for that lesion, because the swollen lymph node was large and may have invaded the surrounding organs. We then performed esophagectomy.
