The presence of metastatic malignancy entails a search for the primary tumor. In this study, two unusual cases of metastatic tumors, one a diffuse B-cell Non-Hodgkin lymphoma (NHL) and the other squamous cell carcinoma (SqCC), to the thyroid gland, revealed two primary sites on further work-up. In view of diffuse B-cell NHL involving the nasopharynx, parapharyngeal and cervical lymph nodes, it was presumed that the involvement of thyroid was secondary. Similarly, because of uncommon occurrence of SqCC of thyroid and proven synchronous SqCC in lung and larynx, the tumor in the thyroid was diagnosed as a metastatic SqCC. |
