Chromoendoscopy with indigo carmin.
Cap polyposis is characterized by rectosigmoid polyps that
have tortuous elongated crypts and are covered by a cap
of fibropurulent exudate. The pathogenesis is unknown,
but the histology suggests that mucosal prolapse may play
a role. The current therapy often used for inflammatory
bowel diseases has frequently been ineffective. Overall,
infliximab lead to symptomatic improvement and histologic
resolution of the polyps.
