A 38-year-old woman, who received surgical operations for panperitonitis developed with unknown cause and for ovarial dermoid cysts 14 and 10 years ago, respectively, was admitted to our hospital requesting further examination of multiple abdominal tumors pointed out elsewhere. Plain X-ray, US, CT and MRI pictures demonstrated, in the abdominal lumen, multiple tumors, 1 to 7cm in size, with calcified wall and soft contents suggesting fat. On laparoscopy, the tumors with whitish thin wall were seen in the abdominal lumen sticking on the lower surface of the liver, the greater omentum and peritoneum. Laparotomy was performed and 36 abdominal tumors were removed in total. Histologically, the surface wall of tumors was composed of vitreous substances partially calcified and the content in most tumors was fat. Although there were no components derived from the germ layers in the tumor content, the tumors regarded as those dis-seminated from ovarian dermoid cysts detected 14 years ago when she had an episode of panperitonitis, on the basis of the clinical features and her past history. There were 4 previous reports of peritoneal multiple dermoid cysts of ovary comprised of fat.
