Dermatology

Our activities include dermatological treatment, education and research.  We always keep it in our mind that ” the result of research and education should be given back to practical field”, and we carry out our research in order to resolve problems caused from clinician’s perspective.  Our education policy is fostering not only specialists of dermatology but also general physicians who never overlook any common skin diseases.  In particular, the leaders specializing rheumatology, immunology, oncology or skin surgery conduct researches as well as clinical practice such as diagnosis and therapy of patients.
Clinical conferences and research sessions are regularly held.  Subgroups hold small conferences, research meetings and journal seminars.  Each doctor actively attends dermatological conferences.  There are a lot of opportunities for studying at overseas or domestic institutes.  We always make the greatest effort to maintain high standard of expertise.

History

Our department was launched when Prof. Jun Yamazaki (Tokyo University) was welcomed to Gunma University as the first chairman in 1944. Then, Prof. Hidekazu Ishikawa (Tokyo University), as the second chairman in 1972, made clinical practice and research on systemic sclerosis as his lifework. The fundamentals of clinical practice and research for collagen diseases were established during this period. In 1992, Prof. Yoshiki Miyachi (Kyoto University) became the third chairman. He had made great contribution to promote clinical practice and research for skin allergology and skin surgery, in addition to collagen diseases practice and research. The present Prof. Osamu Ishikawa was promoted to the fourth chairman in 1999. Since then, we have actively absorbed new scientific knowledge and technology in the field of cell biology molecular biology. Now, our research activities have covered wound healing, skin allergology, skin oncology and skin surgery as well as autoimmune rheumatic diseases.
One young dermatologist has been studying abroad in United States.
Recently, pressure ulcer is one of the severe problems among aging society. We actively spread out the research and clinical practice in the field of wound healing.Proffessor Ishikawa is widening his activities as the director of Gunma University Hospital four years since 2007, and vice-president (education and international exchenge) of Gunma University since 2011.
