The squamous cell carcinoma was compared with the intra epithelial lesions about the tone of dyskeratosis. The color was analyzed by RGB of 24 bit. It was not able to be said that the color of dyskeratosis was a useful findings for the discrimination of the squamous cell carcinoma or the intra epithelial lesions. The discrimination of squamous cell carcinoma or the intra epithelial lesions should value the findings other than the color.
We analyzed changes in cancer screening of uterine cervix in mass screening by Akita Kouseikai. Markedly increase of juvenile dysplasias and cancers in near decade was pointed out. Particularly, increase of juvenile dysplasias was conspicuous. Effective induce of cancer screening for young women is indispensable.
We report a case of diffuse large B-cell lymphoma (DLBCL) of the retroperitoneum showing a cohesive cytological pattern. Imprint smears of the lesion were easily diagnosed as DLBCL by Diff-Quick staining, but tumor cells with large round nuclei and clear pale cytoplasm also showed a cohesive pattern in Papanicolau staining, meaning that clear-cell renal carcinoma could not be ruled out. DLBCL rarely affects retroperitoneal lymph nodes or soft tissue. Our case thus indicates that DLBCL may show a cohesive pattern both in cytological and histological specimens.
