Thanks for Dr. Zhao's analysis about this case. To me it is difficult to make a definite diagnosis at first eye. At some points I finally give a positive diagnosis of malignancy. The cellularity which Dr. Zhao has referred is the most important criteria. The another one is the architecture forming glandular particles with little lymphocytes infiltration.
According to Zhao's advice, several markers such like CK5/6, calretinin and mesothelia will be done based on cell block.
