A Case of Epstein-Barr Virus-Positive Diffuse Large B-Cell Lymphoma Occurring in Thyroid Gland

Abstract

Epstein-Barr virus positive diffuse large B-cell lymphoma is very rare malignant tumor in thyroid gland. Compared to Epstein-Barr virus negative diffuse large B-cell lymphoma, it tends to have more extranodal involvement, does not respond to chemoimmunotherapy well, and has worse prognosis. We have encountered a patient with Epstein-Barr virus positive diffuse large B-cell lymphoma of thyroid gland in 75-year-old female presenting with aggravating dyspnea and neck pain.
