Ovarian immature teratoma during pregnancy : a case report

الملخص EN

Germ cell tumors are derived from the primordial germ cells of the ovary and immature teratoma is the second most common germ cell malignancy.

About 50% of pure immature teratomas of the ovary occur in women between the ages of 10 and 20 years, and they rarely occur in pregnancy.

A 21-year-old woman, gravid 1, para 0, at 18 weeks of gestation, was incidentally diagnosed with a right ovarian mass 180 mm by 200 mm, 160 mm in diameter, during a prenatal ultrasound scanning.

She underwent surgery by unilateral salpingo-oophorectomy and surgical staging.

The result of pathology showed a stage 1a grade 1 immature teratoma of ovary.

Her pregnancy continued until term.

At 38 weeks she delivered with breech presentation a normal 2900 g male newborn by cesarean section.

Although immature teratomas of ovary during pregnancy are rare, clinicians should consider their eventuality in younger pregnant women in asymptomatic cases.
