Abstract

Primary Burkitt lymphoma of the thyroid is an extremely rare entity with only a few reported cases. A female patient in her 70s with Hashimoto’s thyroiditis presented with a 2-month history of progressive left-sided neck swelling. Ultrasound examination revealed a multinodular goitre and fine needle aspiration (FNA) showed no signs of malignancy. The rapid growth of the thyroid mass raised the concern of a lymphoproliferative process. After left thyroid lobectomy and histopathological examination, the diagnosis of Burkitt lymphoma was made and the patient was included in a randomised study providing chemotherapy following a dose adjusted EPOCH-R regimen. Clinical remission was reached after 6 cycles of chemotherapy. There were no signs of relapse on follow-up, 1.5 years after the end of the treatment. Fast growing thyroid nodules in HT warrant a high index of suspicion. Despite no signs of malignancy after FNA cytology, these nodules may need further investigations.
