Metastatic XXXX of the submandibular lymph nodes with @entity1544 : report of a case.

@entity3557 @entity1 @entity1377 @entity5 @entity957 @entity1544 @entity259
We report a unique case of metastatic @entity3557 of the submandibular lymph nodes with @entity1544 . A 48-year-old @entity1 was referred to our hospital for treatment of a @entity259 and right submandibular masses. @entity5 , 2 cm in its largest dimension, was palpated in the right lobe of the thyroid gland. The masses in the submandibular region measured up to 3 cm in diameter. Each submandibular @entity5 had a cystic cavity containing slightly opaque fluid. Aspiration cytology of the thyroid established a diagnosis of @entity1377 . Aspirated material from the cystic cavity of one of the submandibular masses contained only keratinized material with a thyroglobulin level of 175 ng/ml. The @entity1 underwent a total thyroidectomy with modified radical neck dissection. Microscopic examination of the resected specimen confirmed a diagnosis of @entity1377 of the thyroid, as well as well-differentiated @entity957 with cystic changes in the submandibular lymph nodes. Focal immunoreactivity for thyroglobulin, combined with the absence of any other possible primary lesions in the head and neck region, suggested metastatic @entity3557 of the submandibular lymph nodes with @entity1544 .
