Abstract
BACKGROUND: Krukenberg tumors are ovarian metastatic adenocarcinomas with a primary origin usually located in the stomach, colon, gallbladder, pancreas, or breast. Occasionally, these tumors produce virilization in the affected individual due to androgen production by luteinization of the tumoral stroma. It is believed that during pregnancy these tumors are more likely to increase androgen production due to the elevated levels of human chorionic gonadotropin (hCG). High maternal androgens can cross the placenta producing virilization of the female fetus.
CASE PRESENTATION: A 46,XX newborn female, whose mother was diagnosed with a metastatic ovarian tumor during her second trimester of gestation associated with worsening hirsutism and acne, was found to have ambiguous genitalia at birth. Testosterone levels in both the mother and infant were elevated. Follow-up laboratory tests showed progressive normalization of circulating androgens after delivery.
CONCLUSIONS: Krukenberg tumors are rare and may produce virilization of the mother and the female fetus when present during pregnancy.
