Primary Non-Hodgkin's T-Cell Lymphoma of the Thyroid Gland Complicating Hashimoto's Thyroiditis: Case Report

This case report presents an extremely rare case of primary non-Hodgkin's T-cell lymphoma of the thyroid gland complicating Hashimoto's thyroiditis and discusses the clinical history, findings, treatment, and prognosis. Although the place of surgery in the treatment of thyroid lymphoma is controversial, in this case, surgery followed by three rounds of chemotherapy with cyclophosphamide, doxorubicin, vincristine, and prednisone, and radiation therapy to neck and mediastinum were a very effective treatment for the disease so that no relapse has been detected during 3-year follow-up.
