Carcinoma arising in enterocutan fistulae of Crohn's disease patients: description of two cases.

ABSTRACT

Rarely, carcinoma arises from the fistulous tract of Crohn's disease. Adequate radiological examination often produces misleading pseudonegative findings. We reported two cases of fistula cancers treated with infliximab. The short time-span between the administration of this drug and the diagnosis of cancer makes the correlation between the two unlikely.
