(a) H&E revealing a neoplasm of glandular epithelial origin within the lamina propria. (b) The cells showed a homogenous morphology with few cells showing atypia and mitotic figures. (c) Clear cells were observed in some areas. The neoplastic cells were positive for (d) CK-7, (e) CK-13, and (f) CK-14 and negative for (g) p16. (h) PAS with diastase digestion (i) and mucicarmine were also detected within the tumor. Scale bar: (a, c) = 80 μm; (b, d, e, f, g, h) = 20 μm.
