The occurrence of CT (collision tumor) at the EGJ (esophagogastric junction) is rare, with few cases reported in the literature. Therefore, reports evaluating treatment and survival of this group are scarce. In this article, we report a collision case between esophageal squamous cell carcinoma and adenocarcinoma at the EGJ, operated in Abdomino-Pelvic Surgery Division of Brazilian National Cancer Institute.
