Spending along with Dermatomycoses

The skin is the largest organ and forms the outermost part of the body. The skin and many cutaneous disorders are closely related to exogenous factors such as life style, environmental conditions, and so on. Therefore, it is very important to consider the skin and cutaneous disorders from a socio-environmental viewpoint. Since joining the Department of Dermatology about 40 years ago, I have been studying dermatomycoses and medical mycology as a subspecialty. During this period, the nature of cutaneous mycoses has changed. This paper covers the following topics: 1) gradual increases in the number of cases of tinea pedis among the elderly and children, 2) changes in prevalence of Microsporum canis infection, 3) increases in the number of cases of dermatophytosis caused by Trichophyton tonsurans in recent years, 4) the epoch-making development of a treatment for onychomycosis, 5) transition of the clinical type of cutaneous candidiasis, 6) expansion of knowledge about the pathogenesis and mycology of Malassezia species, 7) decreased prevalence of deep dermatomycoses such as sporotrichosis or dematiaceous fungus infection
