Two typical HE tumor tissue slices. (A) The squamous cancer cells were polygonal and arranged as strips, and their nucleuses were round or orbicular-ovate, most of which even had pathologic change, like karyomegaly and anachromasis (H & E stain, ×200). (B ) Except the performance of squamous cell carcinoma components, adenocarcinoma cells were cubic or columnar and arranged like glandular tube (H & E stain, ×200).
