Microscopic imaging of haematoxylin and eosin (HE)-stained tumour cells. (A) Tumour tissue was separated into nodules of different sizes by coarse fibrous tissue. The cells are shown at 100× magnification after HE staining. (B) Tumour cells within nodules are arranged in a glandular vesicle shape, with rich intervesicular blood sinuses. The cells are shown at 200× magnification after HE staining. (C) Mitotic figures are observable at high magnification. The cells are shown at 400× magnification after HE staining. (D) Tumour cells of uniform size and shape (round or polygonal) are shown. Most of the cells are well defined, with abundant cytoplasm, and are translucent or eosinophilic. The cells are shown at 400× magnification after HE staining
