癜風，尋常白斑，乾癬，皮膚結核—西日本における皮膚科疾患の地理的分布

TINEA VERSICOLOR, VITILIGO, PSORIASIS AND TUBERCULOSIS OF THE SKIN

I．緒言

　昭和40年7月より昭和41年6月の間に西日本（中国，四国および九州の16県）の皮膚科医により診断された表記疾患の地理病理学的検討を行つた。集められた資料は郡市別および県別の人口10万当りの発生率であり，これより海岸，山間地域に区分して，地勢，気象，産業などと発生状況との問に関連が認められるか否かについて検討した。

1. The incidence of tinea versicolor was lower in the area of Sanin Setonaikai climatic type, including the northern part of Kyushu. It was higher in the area with higher tempe-rature and larger amount of rain (Tokushima prefecture, Middle Kyushu, and Southern Kyushu). It was extremely high in the area on the coast and in the industrial zone.

2. The geographic distribution of vitiligo vulgaris was similar to that of tinea versicolor. Its frequency was higher in the suburbs of the city where the samples were collected.

3. The frequency of psoriasis vulgaris was not necessarily higher in the city, but some special parts of Kumamoto, Saga and Kagoshima prefecture. This suggests the existence of genetic factor in this disease.

4. The frequency of the skin tuberculosis was higher in the area with old people. It was reversal correlation with that of pulmonary tuberculosis.

Comparing with the statistics of the skin tuberculosis from the Department of Dermatology of Kyushu University from 1945 to 1954, the number of patient of lupus miliaris dissemina-tus faciei increased significantly.
