Abstract
In a statistical survey of 3, 978 dermatomycosis patients (7.1% of all new patients) visiting the dermatology clinic of Otaru City Hospital between 1971 and 1988, dermatophytosis (2, 645 cases) was the most freqent complaint followed by cutaneous candidiasis (1, 216 cases), tinea versicolor (96 cases), and other dermatomycoses (10 cases).
Dermatophytosis patients were composed of 1, 840 cases of tinea pedis, 369 tinea cruris, 342 tinea unguium, 277 tinea corporis, 69 tinea manuum (2.3%), 53 tinea faciei, 15 tinea capitis, and 1 tinea profunda. The incidence of tinea pedis and tinea unguium (especially among aged females ) increased during the survey period. The incidence of tinea manuum in Hokkaido district was lower than in any other area in Japan.
Of the 2, 311 samples, 930 Trichophyton rubrum (TR), 542 Trichophyton mentagrophytes (TM), 3 Trichophyton verrucosum, 1 Trichophyton violaceum, 49 Microsporum canis (MC), and 17 Epidermophyton floccosum were isolated. TR was the predominant species in all clinical types except tinea of the scalp and face, and was responsible for 54% of tinea pedis, 88% of tinea unguium, 78% of tinea corporis, and 87% of tinea cruris. The number of patients with tinea pedis due to MC increased after 1978.
Of 1, 216 candidiasis patients, there were 494 infantile candidiasis, 199 erosio interdigitaris, 179 candidial intertrigo, 96 genital candidiasis, 93 candidial paronychia et onychia, 66 oral candidiasis and 89 cases with atypical clinical signs. Temporary increase of infantile candidiasis was observed between 1972 and 1978.
