Follicular lymphoma (Patient #2). a Enteroscopic view in the ileum before treatment. b A probe-based confocal laser endomicroscopic image shows the homogenous cells packed with polygonal capillary vessels in a “soccer ball-like pattern”. c Enteroscopic view in the ileum after rituximab monotherapy. Slightly reddish follicles are observed. d A probe-based confocal laser endomicroscopic image does not show a “soccer ball-like pattern” after rituximab monotherapy.
