Multiple intraabdominal parasitic cystic teratomas

We report an interesting case of multiple intraabdominal dermoids in a patient who had undergone an excision of ovarian dermoid cyst earlier and presented with recurrence of symptoms. She had masses all over the abdominal wall, omentum, and pouch of Douglas and a dermoid cyst in the ovary as well. It is generally believed that autoamputation and reimplantation of an ovarian dermoid cyst is the most common cause of omental teratomas. Abdominal pain is the main presenting symptom of these tumors, and on physical examination a mobile abdominal or pelvic mass is often found. Both ultrasonography with color-flow Doppler ultrasonography and computed tomography are helpful in the diagnosis of dermoid tumors, but the correct diagnosis of omental localization is extremely difficult. We removed all the masses laparoscopically. Literature search did not reveal such extensive parasitic dermoids in any patient.
