腎血管筋脂肪腫15例の臨床的検討

Abstract

1)手術を施行したのが6例(腎摘除術3例, 腫瘍核出術3例), 経過観察のみで経過しているのが9例であった. 2)腎摘除術3例のうち1例は術中迅速病理検査で脂肪肉腫と診断された.病理検査, 特に迅速病理検査では脂肪肉腫とAMLとの鑑別に注意すべきと思われた. 3)当科で結節性硬化症に合併したのは1例のみで, この症例は対側腎に平滑筋腫を合併していた. 4)現在まで経過観察している症例のうち, 1年以上の経過観察が可能であった5例では腫瘍doubling timeが大きく, 1年以上の経過観察後に腫瘍核出術を施行した2例では腫瘍doubling timeが1年未満と小さかった

Fifteen cases of renal angiomyolipoma seen between May, 1988 and October, 1994 in our hospital are presented. Surgical treatment was performed in 6 cases, 1 of which was falsely diagnosed as liposarcoma by frozen specimen during the operation. Nine cases were only followed-up by ultrasonography and/or computed tomography. In 2 cases, in which enucleation was performed after a follow-up period of more than one year, tumors were inclined to grow rapidly. In 5 cases, which were not operated and followed-up for more than one year, tumors were inclined to grow very slowly.
