The carcinoid tumour in Meckel's diverticulum: how to treat young adults with appendicitis?--Case report.

This case reports the concomitant and unexpected finding of carcinoid tumour within a Meckel's diverticulum presenting as an acute abdomen due to gangrenous appendicitis in a young adult male. Both Meckel's diverticula and carcinoid tumour are rare clinical entities, and carcinoid tumours occurring within a Meckel's diverticulum are even more uncommon. The initial clinical presentation of carcinoid tumours occurring in a Meckel's diverticulum is usually similar to that of appendicle carcinoids.
