Aim: To investigate the pre-vaccination epidemiology of genital human papillomavirus (HPV) infections and genotypes in women with abnormal cytology in Nagasaki, Japan.
Material And Methods: We performed Pap smear tests, biopsies and HPV genotype testing in Nagasaki Prefecture from August 2007 through November 2009.
Results: During the study period, serial samples of uterine cervical specimens were obtained from 539 subjects with abnormal cytology and/or squamous intraepithelial lesions (SIL) confirmed previously, or with clinically suspected invasive cervical cancer.
The aim of this study was undertaken to clarify the cytological characteristic of the "condensed clusters of stromal cells," which may be recognized in endometrial glandular and stromal breakdown (EGBD) cases. The material consists of 60 cases of cytologic smears for which histopathological diagnosis was obtained by endometrial curettage; they comprised 30 cases of EGBD and 30 cases of endometrioid adenocarcinoma grade 1 (G1). The following parameters were examined for "condensed clusters of stromal cells" in EGBD and for "clumps of cancer cells" in G1, respectively: (1) the occurrence of "condensed clusters of stromal cells"; (2) the nuclear shape; (3) a longer/shorter axis ratio in cell nuclei; (4) the area of cell nuclei; (5) the presence of overlapping nuclei; (6) nuclear crowding; (7) immunostaining.
