Dermatopathology Teaching

Pathology is a main pillar of dermatology, and its study is a must if residents are to gain versatility in diagnostic ability. On Wednesdays, Professor Hiroshi Shimizu teaches young
doctors by using newly received specimens. On Thursdays, I teach them the basics of dermatopathology so that they’re able to acquire systematic knowledge in one year.
As in the previous year’s classes, residents are provided with pathological specimens for each study item in the Lever’s Histopathology of the Skin (10th ed) textbook, they do their homework, and they give presentations in class. The tumorous diseases are our main concern, and they should be taught early in the course. Although they’re in the latter half of the Lever’s textbook, I cover pathological findings of basic tumorous diseases during the first several classes.

The residents basically take this course twice in the two years of their residency program. Last year the class had various enrollees, including graduate course students who wanted to come back to review what they’d learned, doctors at the university hospital who wanted to take courses of their choosing, and some undergraduate students who probably decided to come after listening to my “promotion” talk in the university classes. To respond to their genuine ambition and curiosity, and to strengthen the efficiency of learning, it has been necessary to present pathologic specimens that are useful for learning and that are beautiful. To improve the learning environment, I borrowed pathological specimens from doctors at other institutions; prepared a box of slides for self-study, which covered the major disorders; and had the old specimens newly stained by the pathology department of the university. I expect that the classes will be full of various enrollees this year, again.
