尿閉を伴った幼児卵巣類皮嚢胞腫茎捻転の1手術例

Abstract

The patient was a girl 2 years and seven months of age. Because of vomiting, she was examined by a pediatrician on November 25, 1993. Her condition seemed to improve a little, however on November 29, she suffered from fever and anuresis, and was hospitalized in a surgical department. Physical examination revealed a distended abdomen and tenderness in the abdomen, but no tumor. An ultrasound examination was performed on the abdomen and a CT scan was performed on the pelvis. From the results of these tests, the patient was diagnosed with torsion of tumor in the left ovary. Peritoneotomy was performed and the result of the surgery showed that the tumor originated from the right overy, and was incarcerated in the pelvic cavity, exerting pressure on the base of the bladder. The tumor was 7×6×6cm in size, and contained hair balls and 15g of serum. Pathohistologically, fatty tissues, as well as developed crinis and bone tissues were found. From these findings, the tumor was was diagnosed as ovarian dermoid cyst. It is extremely rare for ovarian dermoid cyst to occur in children, and in Japan, there have been few cases of ovarian dermoid cyst in children under 7 years of age. Nonetheless, because of their age, one must be careful when handling these cysts.
