Transient Thyrotoxicosis in Molar Pregnancy

Functioning Endocrine Tumors in Pregnancy: Diagnostic and Therapeutic Challenges

The occurrence of endocrine tumors in pregnancy poses several diagnostic and therapeutic challenges. Although rare, functioning tumors involving the pituitary, thyroid, adrenal, and pancreas are reported in the literature. Timely diagnosis and management of these tumors are essential as they might lead to adverse maternal and fetal outcomes if left untreated. This review is an attempt to characterize various functioning tumors that could occur in pregnancy, their clinical features, diagnosis, and management.

Delivery of Euthyroid Baby following Hyperthyroidism in Twin Gestation with Coexisting Complete Hydatidiform Mole

Context

Gestational trophoblastic disease (GTD) is a rare complication of pregnancy, ranging from molar pregnancy to choriocarcinoma. Twin pregnancies with GTD and coexisting normal fetus are extremely rare with an estimated incidence of 1 case per 22,000–100,000 pregnancies. Molecular mimicry between human chorionic gonadotrophin (hCG) and thyroid-stimulating hormone (TSH) leads to gestational trophoblastic hyperthyroidism (GTH) which is further associated with increased maternal and fetal complications. This is the first reported case in literature describing the delivery of a baby with biochemical euthyroid status following a twin pregnancy with hydatidiform mole (HM) associated with gestational trophoblastic hyperthyroidism (GTH).

Case Description

A 24-year-old G4 P3 Caucasian female with twin gestation was admitted to hospital for gestation trophoblastic hyperthyroidism. She was later diagnosed to have twin pregnancy with complete mole and coexisting normal fetus complicated by gestational trophoblastic hyperthyroidism (GTH). Despite the risk associated with the continuation of molar pregnancy, per patient request, pregnancy was continued till viability of the fetus. The patient underwent cesarean section due to worsening preeclampsia and delivered a euthyroid baby at the 24th week of gestation.

Conclusions

Twin pregnancy with gestational trophoblastic disease and coexisting normal fetus is associated with high risk of hyperthyroidism, and careful monitoring of the thyroid function test along with dose titration of thionamides is of utmost importance throughout the gestation. If normal thyroid hormone levels are maintained during the pregnancy, euthyroidism could be successfully achieved in the baby.

Advanced gestational trophoblastic disease: A case report of medical management prior to surgical intervention

BACKGROUND

Gestational trophoblastic disease (GTD) is a rare developmental form of proliferative trophoblastic tissue. Sparse literature exists regarding the optimal management of patients with advanced GTD, but the definitive treatment is urgent surgical intervention.

CASE

A 48-year-old woman presented advanced GTD. She was medically managed for hypertension and hyperthyroidism prior to surgical intervention in order to minimize the risk of anesthetic and surgical complications.

CONCLUSION

Advanced GTD is rare. Undetected GTD can result in complications such as thyrotoxicosis, which poses substantial risks in the peri-operative period. Appropriate identification and management of this clinical problem are essential to prevent complications as well as subsequent malignant sequelae.
