小児にみられた左卵巣奇形腫の膀胱穿孔例

Abstract

A 4-year-old girl was seen by our clinic with cloudiness of urine after severe abdominal pain. Intermittent pyuria was confirmed by urine examination for 20 days. Cytoscopically, thumb's head sized tumor was observed at the dome of the bladder. A malignant tumor was suspected and an operation was performed. The left ovarian abscess was adhesive to the bladder wall with perforation into the bladder. Histologically, no invasion of the ovarian teratoma was observed in the bladder wall except for inflammatory changes. Not only well developed epidermis, hairs and sweat glands but also smooth muscle and brain tissue were observed and diagnosis of benign ovarian teratoma was determined.
