Abstract

This study was done with 5,980 cases of dermatomycosis of dermatological patients in Chnnnam University Hospital for 10 years(1976~1985). And the literatures concerning all fungal diseases reported in Korea were reviewed. The results were summarized as follows ; Among total dermatological patients, the average annual incidence of dermatomycosis was about 15+3%. Dermatophytosis was the most prevalent(77.34%), followed by candicliaais(14.38%), tinea versicolor(7.78%), sporotrichosis(0.45%). Of dermatophytosis, the decreasing orders of clinical localization by the incidence were T.pedis(42.2%), T.cruris(25.9%), T. manum(10.3% ), T. corporis(10.0%), T. ungium (6.2%), T.facialis(4.2%), and T. capitis(2.2%). The organisms identified from dermato phytoses were generally 9 species ; the decreasing orders of frequency were Trichophyton rubrum(59.4%), T. mentagrophyte(27.9%), Microsporum canis(8.5%), Epidermophyton floccosum(2.4%), T. ferrugineum(0.9%), and others(M. gypseum, T. schonleinii, T. violaceum, T. verrucosum). The most common causative organism was T. rubrum, but that of T. corporis and T. capitis was M. canis, which showed a continuous increase on the annual variation of dermatophytes. Of candidiasis, the most common clinical form was cutaneous candidiasis, which was prevalent under 10 years old. But vulvo-vaginitis and paronychia highly developed between 3rd and 5th decades. The occasion with precipitating faetors was 10.4% of total candidiasis, of which tuberculosis and diabetes mellitus were prevalent. Of T. versicolor patients, the peak age was 3rd decades but some cases were infant and child. Of sporotrichosis, the most common clinical location and form were hand and lym phatic respectively. The peak age was between 4th and 5th decades, and the most prevalent occupation was farmer. Of other deep mycosis, there were each case of cryptococcosis, systernic candidiasis, and Wangiella derm,atitidies infection.
