Background: Few medical education programs provide hands-on classes using electronic medical charts for a large number of students.
Methods: To simulate a medical interview, third- and sixth-year medical students viewed electronic medical chart samples on a screen, created by FileMaker, and discussed patient management. Following this, they underwent a questionnaire survey.
Results: A total of 63.1 and 76.3% of the third- and sixth-year students responded to the questionnaire, and 87.1 and 78.9% of the responders became interested in the class, respectively, because it focused on hands-on, practical training. A total of 5.6% of third-year students stated that the class was difficult to master but they hoped to continue learning.
Discussion: The adoption of a hands-on class using electronic medical charts interested even junior medical students.

Although papillary thyroid carcinoma (PTC)–type nuclear changes are the most reliable morphological feature in the diagnosis of PTC, the nuclear assessment used to identify these changes is highly subjective. Here, we report a noninvasive encapsulated thyroid tumor with a papillary growth pattern measuring 23 mm at its largest diameter with a nuclear score of 2 in a 26-year-old man. After undergoing left lobectomy, the patient was diagnosed with an encapsulated PTC. However, a second opinion consultation suggested an alternative diagnosis of follicular adenoma with papillary hyperplasia. When providing a third opinion, we identified a low MIB-1 labeling index and a heterozygous point mutation in the KRAS gene but not the BRAF gene. We speculated that this case is an example of a novel borderline tumor with a papillary structure. Introduction of the new terminology “noninvasive encapsulated papillary RAS-like thyroid tumor (NEPRAS)” without the word “cancer” might relieve the psychological burden of patients in a way similar to the phrase “noninvasive follicular thyroid neoplasm with papillary-like nuclear features (NIFTP).”
