Photomicrographs of hematoxylin and eosin–stained colonic tumor sections from F344 rats exposed to Aloe vera non-decolorized whole leaf extract in drinking water, ad libitum, for two years. (A) Adenoma (50×). The exophytic mass with dysplastic hyperchromatic cells (arrows and inset box) was limited to the mucosa without evidence of invasion into the muscularis mucosa. (B) Carcinoma (60×). Note the neoplastic cells invading past the muscularis mucosa (arrows) and the fibroplasia surrounding the neoplastic cells (inset box).
