RESUMEN
OBJECTIVE: To report an extremely rare case of an autoamputated ovary with a dermoid cyst diagnosed during a Cesarean section and review the literature. DESIGN: Case report. SETTING: Tertiary hospital. PATIENT(S): A 33-year-old pregnant woman submitted to Cesarean section and was incidentally diagnosed with absence of the right ovary, implanted in the cul-de-sac. INTERVENTION(S): Cesarean section and extraction of a pedunculated tumor formation from the cul-de-sac, adhesiolysis. MAIN OUTCOME MEASURE(S): Histologic analysis of the extracted morphoma confirmed the diagnosis of a dermoid cyst with coexistence of residual ovarian tissue. RESULTS: The patient had an uneventful postpartum period and was discharged home. CONCLUSION(S): Ovarian autoamputation is an extremely rare phenomenon that has uncertain etiology; it may develop after ovarian torsion or torsion of a dermoid cyst. It may be asymptomatic. Usual site of implantation is the greater omentum.
