Serous EIC in adenomyotic cyst of the cervical stump (case 3). Serous EIC was present in the adenomyotic cysts by showing a slightly papillary contour with fibrous cores and the cells displayed hobnail cellular morphology and significant atypia a, b. The serous EIC showed p53 over expression c and a high Ki67 index d. A focus of EmGD and serous EIC (arrow) was seen in the adjacent area of one serous EIC lesion e, f. The EmGD lesion showed p53 over expression g and a relatively lower Ki67 index h. (Original magnifications: A, E*50; C, D*100; B, F-H*200)
