Advances in Clinical Cytology describes the ultrastructural dynamics of endometrial hyperplasia and neoplasia. This book contains 11 chapters that evaluate the meaning of endometrial aspiration in gynecological application and address the morphologic response of hyperplastic and neoplastic endometrium to exogenous progestogens. Some of the topics covered in the book are the evaluation of the methods of cytological sampling; population screening for cervical cancer; advances in pulmonary cytology; and selection of high-risk cases of cancer development for screening and collection of specimens. Other chapters deal with the evaluation of cytology as a method of screening, as well as the cytological features of human polyomavirus-infected cells. An analysis of the functional connections between epithelial cells is provided. The concluding chapters are devoted to the morphology of the cell surface and the method for staining smears. The book can provide useful information to doctors, cytologists, students, and researchers.
