[Tumors of Meckel's diverticulum].

The presentation of a rare case of leiomyoma of Meckel's diverticulum in a boy of 5 yr forms the starting point for a discussion of such cancers. In adult age, the complication is not so rare as the sporadic publications would suggest, incidence of tumoral forms being around 1 : 50 M.D. with a high malignancy frequency. In paediatric age, on the other hand, the tumoral degeneration of a M.D. is an exceptional occurrence: a review of more than 1,200 reported cases and personal experience (48 cases of M.D. in 15 yrs) confirm the rarity of the observation. The need to seek M.D. on each occasion and remove it to prevent the risk of tumoral degeneration in adult age is stressed. M.D. surgical removal tecniques are commented on and emphasis laid on the desirability of ample intestinal resection in cases of cancer of the diverticulum.
