The purpose of this study is to obtain an "in vivo" confirmation that mesalazine induces the gene expression of μ-protocadherin and other related genes in the colon mucosa, as demonstrated in some "in vitro" experiments. .
Pilot Trial, single-blind, parallel group on biopsy specimens of healthy colon mucosa in patients with precancerous lesions of the colon and rectum (adenomas) treated with mesalazine.

Inclusion Criteria:
The following inclusion criteria was deleted according to Amendment n. 01 approved by the Ethical Committee on 19/dec/2014:
- diverticular disease/diverticular colitis;
The rationale of this change is that the presence of diverticular disease/diverticular colitis does not contribute to the definition of the trial primary end-points and represents a critical point during the patient selection with an impact on duration and conduction of the study.
Exclusion Criteria:
