A 31-year-old male patient presented with a rapidly growing neck mass with normal thyroid function tests. Ultrasonography showed thyroidal expansion, a hypoechoic nodule that completely filled the right lobe, and 2 hypoechoic
lymphadenopathies in the right jugulodigastric chain. The patient underwent right total and left subtotal
thyroidectomy, following the diagnosis of
nodular goiter; however, postoperative histopathological evaluation demonstrated primary
Burkitt's lymphoma of the thyroid gland. The
tumor was staged as stage 1, and R-
hyper-CVAD protocol (
rituximab, hyperfractionated
cyclophosphamide,
vincristine,
doxorubicin and
dexamethasone) was administered. The protocol was changed to R-CHOP after 4 cycles due to recurrent grade III/IV
cytopenias and
febrile neutropenia. The PET-CT scans performed after
chemotherapy and at the 6-month follow-up were normal. In summary, we reported a case with a diagnosis of
Burkitt's lymphoma, which is a rare type of primary thyroid
lymphoma.
