This case report describes a 60-year-old male with a collision carcinoma of the oesophago-gastric junction. Collision carcinoma (CC) is the synchronous occurrence of tumours of different histological type arising in the same organ without histological admixture.

The CC in this case report was composed of moderately differentiated adenocarcinoma and poorly differentiated neuroendocrine carcinoma.
