This work was done to study the variant histopathological pictures of the endometrium of postmenopausal bleeding [PMB] patients. 150 endometrial specimens of PMB cases were received at the Gynecological Laboratory of Assiut University Hospital. They were routinely processed, stained by hematoxylin and eosin and examined. PMB causes were classified into organic and non-organic. The former was 41% while, the later was 59% of the cases. The most common organic cause of bleeding was endometrial hyperplasia [36%]. Proliferative endometrium was the commonest cause of non-organic PMB [31%]. Endometrial carcinoma was found in 4% of the cases. The majority of PMB patients were in age ranging from 45 to 50 years [55%]
