ABSTRACT
The incidence of non-Hodgkin lymphoma (NHL) during pregnancy is quite low. There have been a few anecdotal reports of NHL arising in the thyroid gland. Here, we present a 28-year-old female patient who developed a neck swelling, pain and respiratory distress in the 17th week of her first pregnancy. She was diagnosed as having an aggressive NHL of the thyroid gland after subtotal thyroidectomy. She had 4 cycles of chemotherapy before successful cesarean delivery of a healthy, full-term male infant at 39 weeks of gestation. Four additional courses of chemotherapy were administered, after which the patient did not show any signs of relapse.
