Welcome to Cytopathology Case Videos, CCVs!

日本語

This page provides the links to CCVs. CCVs are short videos which present a cytology case. We have launched this site so that CCVs can help actual specialists and those who want to be a specialist to learn and train in cytopathology.

First, please select the sample type you want to watch. A list, based upon your selection will be presented below. The list will present 10 cases at a time. If you want to see cases beyond those listed, please click 'Next'.

"Specimen" as shown in the list provides more specialized information detailing the sample type. For example, urinary tract includes voided urine, catheterized urine in bladder, bladder lavage, etc..

The videos you select to view are stored on vimeo.com. Click on the link displayed in blue letters to open the video of the case. All videos are mp4 files of about 2-4 minutes length and a field of view of 1440x1080. Of course, you can also observe them on your smartphone.

Videos start with a page briefly introducing the case and then present a panoramic microscopic image of the cytology specimen. A number of regions are then indicated on the image. Next, those areas will be presented, in order, as microscopically enlarged images by using 10x or 40x objective lenses. Microscopic images are presented as z-axis video for cytology (Zavic), which was introduced by Dr. Katsushige Yamashiro to express the three-dimensional structure of the objects of cytology observation. The video closes with an example of cytopathological diagnosis. This diagnosis may not always be correct and should be evaluated critically.

If you find CCV useful, please contact us by email, sapporoyam@mac.com. We can create a free video from the glass slide of your cytology laboratory and make it possible for other experts to access your CCV from this site. The CCV can display the name of the hospital that provided the glass slide, but it can also be hidden. You can use CCVs for cytology training meetings, etc.. In addition, there is no information other than the link and sample type on this site, so there is no need to worry about leakage of personal information.

If you would like to make such videos by yourself, please contact us and we will inform you how to do it.
