Acceptable diastase resistant periodic acid Schiff (DPAS) positivity. (A) A group of malignant epithelial cells two of which contain intracytoplasmic magenta body-like DPAS positivity with indentation of the adjacent nuclear membrane (DPAS stain, AC5); (B) and (C) dissociated malignant epithelial cells showing structured intracytoplasmic DPAS positivity with indentation of the adjacent nuclear membrane (DPAS stain, AC5); (D) a group of malignant epithelial cells containing intracytoplasmic DPAS positivity that sometimes lacks internal structure but does produce nuclear membrane indentation (DPAS stain, AC5).
