腹部停留睾丸から発生したDermoid Cystの1例

Abstract

A case of dermoid cyst in cryptorchid testis is reported. A 26-year-old man was seen on October 28, 1976 with the complaint of abdominal mass, first noted 4 years previously. He denied genitourinary or other symptoms. Physical examination revealed a well defined, movable mass in the right abdomen. The left scrotal contents were absent. Laboratory values, including complete blood count, blood chemistry, urinary and blood hormone levels were all within normal limits. Serum alpha-fetoprotein titer was negative. A plain film of the abdomen showed teeth in the soft tissue mass. Abdominal aortography demonstrated a hypovascular lesion and somewhat dilated left spermatic artery. On November 17, 1976 surgical extirpation was made and resulted in excellent postoperative course. Histopathological diagnosis was benign cystic teratoma (dermoid cyst). Approximately 2.5 years have passed postoperatively and there is no evidence of metastasis or local recurrence of the tumor. Follow up serum alpha-fetoproteins and urinary chorionic gonadotropins have been negative. To our knowledge, one case as such has been reported in the literature.
