Tumour lysis in newborn: spontaneous or secondary to antenatal steroids?

Tumor lysis syndrome in premature infant prompting early resection of a large sacrococcygeal teratoma: a case report

BACKGROUND

Sacrococcygeal teratomas (SCTs) are the most common congenital neoplasm and often require resection soon after birth. There are rare reports of cardiac arrest during surgery due to manipulation of the tumor triggering secondary necrosis and hyperkalemia.

CASE PRESENTATION

This case describes a very preterm infant with a SCT who develops spontaneous preoperative tumor lysis syndrome (TLS). The medical team utilized rasburicase and the patient underwent total gross resection at 40 h of life.

CONCLUSIONS

We emphasize the importance of the early recognition and management of tumor lysis syndrome in SCT with rasburicase, aggressive management of hyperkalemia and consideration of early resection of SCTs even in the case of a very premature infant.

Diffuse Large B-Cell Lymphoma During Third-Trimester Pregnancy and Lactation

BACKGROUND

Diffuse large B-cell lymphoma is the most common type of non-Hodgkin's lymphoma affecting pregnancy. These tumors may be aggressive and rapidly growing in pregnancy. Management is based on the balance of risks and benefits to both the pregnant patient and the fetus.

CASE

We present a case of diffuse large B-cell lymphoma diagnosed in the third trimester of pregnancy. The patient underwent labor induction at 34 weeks of gestation, started a standard chemotherapy protocol postpartum, and breastfed following a timed lactation protocol.

CONCLUSION

Management of lymphoma during pregnancy highlights the need to consider all aspects of proposed oncologic and obstetric care as well as neonatal risks. Considerations highlighted in this case include staging methods, administration of antenatal steroids, timing of delivery, and lactation during chemotherapy.

Malignant rhabdoid tumour of the neck in a neonate

Fetal neck masses are rare, and present a challenge antenatally, during delivery and in making a diagnosis. In this report, we detail the presentation of a neonate with a neck mass diagnosed in the third trimester. The baby was delivered by ex utero intrapartum therapy (EXIT). Investigations sent included an MRI with limited CT cuts, and a biopsy, which lead to the diagnosis of a malignant rhabdoid tumour. This is rare and the overall survival is low.
