光田健輔
Mosuke Murata joined the Zensho Byoin, now Tama Zenshoen Sanatorium in 1909. The chief dermatologist was Kensuke Mitsuda and there was another doctor Chin. Murata belonged to the surgery section, and studied leprosy. He was known for naming a hot nodule of leprosy, "erythema nodosum leprosum" (ENL). There was need to differentiate it from other types of "erythema nodosum", which is usually seen in the lower parts of the body. In his paper, he thanked Kensuke Mitsuda for allowing him to study a total of 67 cases. After writing papers, he went into private practice in 1914.
