Biopsy confirmed tubular adenomas, with a markedly dense, transmural inflammatory infiltrates predominantly composed of eosinophils and crystal-storing histiocytes containing Charcot-Leyden crystals (Figures 1 and 2).
High power H&E showing aggregates of histiocytes within the muscularis mucosa and superficial submucosa. The cytoplasm of the histiocytes contains eosinophilic Charcot-Leyden crystals which are present in the form of fine, granular, and needle-shaped deposits within the macrophage cytoplasm (black arrows).
