• Idelalisib-related mucosal injury show
intraepithelial lymphocytosis of the surface
and crypt epithelium (A) with attenuation
of the surface epithelium (B).
• Large, "exploding" apoptotic epithelial cells
(arrow) are present in 50% of cases.
• Neutrophilic infiltration of the lamina
propria, cryptitis, and/or crypt abscesses
are common findings.
