Ackerman's pattern analysis is an epoch-making leap in the diagnosis of dermatopathol-ogy

which embodies a profound understanding of the whole dermatovenereology. To improve the teaching quality of Dermatovenereology for five year clinical medical students

pattern analysis is introduced into course educational practice

and the diseases that scattered throughout the whole textbook and listed in various chapters or sections are reclassified according to its pathological features. Thus the organic connec-tion of related knowledge points and the lateral contrast network between different diseases is constructed by the central tache of dermatopathology

and therefore makes the course more logical and be more benefi-cial for the undergraduate students to learn and to remember. By the way

the thinking method of pattern analysis will also be an implicit teaching content and imperceptibly instilled to the undergraduate students

and inspired potential and motivation and aroused learning interest

expanded thought train ability to pursue advanced and further studies.
