Carcinoids of the colon and rectum in patients aged 30 and younger.

Carcinoid tumours of the colon and rectum were diagnosed in 26 patients, 30 years or younger, in Sweden during 1969--1970. Patho-anatomical description was adequate in 24 cases and of these 23 were localized to the appendix and one to the caecum. The treatment was appendicectomy and in the last case ceacal resection. None of the patients had carcinoid syndrom. One patient was lost at follow-up, the 5-year survival rate of the remaining 25 patients was 100 per cent.
