東北地方における足菌腫の2例

MYCETOMA PEDIS

緒言

　足菌腫は比較的稀な疾患で，本邦では現在まで20例の症例報告^1〜19）がみられるにすぎない。しかも患者発生を地域別に検討すると，約半数例は関東地方に集中し，ついで中国地方に多い。一方関東以北の地域からの報告としては，大正8年われわれの教室からの1例報告^2）が挙げられるが，この症例は関東地方在住中に本症に罹患したものである。すなわち，現在までのところ本症が関東以北において発症したという確実な証拠はない。最近われわれは，いずれも宮城県内に在住し，県下において感染したと思われる2例の本症症例を相次いで経験した。したがつてこの2症例が，東北地方における発症例としては第1，第2例といえる。

　以下にこれら2症例につき報告し，文献的考按を加えたい。

Two cases of this disease in a 28-year-old female farmer and a 56-year-old male farmer were reported, which were the first and the second reports in Tohoku district.

Histologic specimen had granules. Nocardia asteroides was proved from the lesion. Antibiotics and sulfonamide were effective especially with concurrent use of adrenocortical steroid.
