症例は27歳で,2年前に第1子を出産し,1年前に月経再開した.その後月経異常は認めておらず,エストロゲン分画を含めて卵胞期性腺ホルモンに異常はみられなかった.癒着が強固であったため治療は外科的切開を施行した.本例では根本的に外陰部の炎症が存在し,更に長期にわたり性交がなかったこと,外陰部異常を認識してから受診迄に長期のタイムラグがあったことが陰唇癒着の完成に大きく関与したものと考えられたA 27-year-old female patient consulted us with chief complaints of difficulties of sexual intercourse and urination. On examination, the labia was found to be extensively fused at the midline, with a pinhole opening. We diagnosed it as labial adhesion. We operated on it under lumbar anesthesia. Four months after the operation, there were no symptoms of recurrence. Labial adhesion is thought to be caused by inflammation, lack of sexual activity and estrogen deficiency. It is not uncommon in children and post-menopausal women, but is extremely rare in reproductive women.
