Thyroid Non-Hodgkin Lymphoma: Fine Needle Aspiration Cytology in the Diagnosis, Case Report
Concerning the tumors that affect the thyroid gland, lymphoma is a rare entity. Likewise, the thyroid is a rare site for extranodal lymphoma occurrence. Thyroid lymphoma frequently arises in a lymphocytic thyroiditis background, presenting as a rapidly enlarging goiter, which is occasionally aggressive. It leads to compressive symptoms and may significantly compromise the airways.
Choosing the right treatment requires the identification of the lymphoma subtype and knowledge about the stage of the disease at diagnosis. These factors have prognostic implications, emphasizing the need of early and accurate diagnosis. Due to overlapping features of lymphoma with thyroiditis on cytological analysis, this is not always an easy task.
The authors report a case of thyroid lymphoma and discuss the clinical features and the utility of the available diagnostic tools.
