Introduction:

Mature cystic teratomas of the ovary originate from germinal cells in a failure of meiosis or from premeiotic cells. This may consist of multiple cells derived from one or more of the three germ layers (ectoderm, mesoderm, and endoderm). They are the most common benign tumors of the ovary. They can appear throughout life, measure less than 10 cm, asymptomatic and unilateral, although only 10% of cases can be bilateral.

Objective:

To present the case of a virgin patient with bilateral mature cystic teratoma of the ovary.

Clinical case:

20-year-old patient, virgin. Attended in the Gynecology consultation for volume increase and abdominal discomfort of several months of evolution; Bilateral ovarian mass was detected. Laparotomy with bilateral cystectomy was performed. Histological diagnosis reported mature cystic teratoma of the ovary. He evolved satisfactorily without recurrence.

Conclusions:

Mature cystic teratomas of the ovary are frequent in reproductive age and unilateral; When they do so bilaterally, they occur at low incidences, so prompt diagnosis and treatment are important to avoid complications, recurrences, and guarantee the future fertility of patients.
