生後1カ月乳児の疥癬

・生後1カ月の乳児の疥癬を経験した．

・産科退院後，母親の実家で里帰り中に，3カ月前にイオウ含有入浴剤で疥癬の自己治療歴がある祖父から感染した，と推測した．

・治療はフェノトリンが著効した．顔面，頭部を含む全身に塗布し，塗布後は手にベビーミトンを着用した．今後の小児への適用拡大が期待される．

・小児の疥癬の場合，保護者への適切な外用方法の指導，および実践できているか否かの確認が重要なことを再認識した．

A case of scabies in a one-month-old infant

　

Hara, Shogo1） 1）Hara Dermatology Clinic

　

A 1-month-old male was brought to our hospital because he had been treated with a topical steroid preparation for a skin eruption for 2 weeks in a pediatric department before his initial examination, but it had become worse. Scattered brown papules and small nodules were observed, mainly over his right lower limb and right foot. A direct microscopy examination was positive for scabies mites. After discharge from the obstetrics department the patient resided in his mother’s parents’ home, where his grandfather lived with them. His grandfather had a history of treatment for scabies at another hospital 3 months before, and a strong possibility of transmission from his grandfather was inferred. The patient responded to treatment with phenothrin. Phenothrin is recommended for infants under 2 months of age by the Guideline for the diagnosis and treatment of scabies in Japan (third edition)of the Japanese Dermatological Association.
