We have discussed the following histological topics which have close correlation with the clinical staging of gynecological tumours. 1. Postoperative recording of definite diagnosis according to pTNM and FIGO. 2. Difference of diagnostic criteria between squamous cell and adenocarcinoma of Ia stage of cervical cancer. 3. Differential diagnosis of atypical endometrial hyperplasia and carcinoma in situ in endometrial cancer. 4. Objective findings for corporeal cavity and myometrial invasion of corpus carcinoma. 5.
