Fetiform Teratoma in the Ovary of a 7-Year-Old Girl: A Case Report.

BACKGROUND: Fetiform teratoma, a highly differentiated mature cystic teratoma resembling a fetus, is rare and typically found in the ovaries of women of reproductive age. In this report we describe, to our knowledge, the youngest case of ovarian fetiform teratoma.

CASE: A 7-year-old girl presented with acute abdominal pain. Radiological examinations revealed a 5.2-cm ovarian complex cystic mass with fetal-like components in favor of fetus in fetu and teratoma. After surgical removal, the mass resembled a fetus consisting of a head, two eye slits, two small upper limb projections, and hair. Pathology indicated mature cystic teratoma supporting the diagnosis of fetiform teratoma.

SUMMARY AND CONCLUSION: Although not commonly found in children, fetiform teratoma must be considered in the diagnosis of a child who presents with an adnexal mass resembling a fetus.
