Early onset of colonic adenocarcinoma associated with cystic fibrosis--a case report.

We report the case of the onset of colorectal adenocarcinoma occurring in an 18 year-old patient, suffering from Cystic Fibrosis. This represents a presentation of colon cancer at an earlier stage than previously reported. Despite this, there is an established link between the two diseases although the pathogenesis is, as yet, unknown. This early onset emphasizes yet another association with the disease and encourages clinicians to be aware of potentially disastrous complications.
