Cervical lymphadenopathy revealing differentiated thyroid cancer. Review of the literature and therapeutic approach.

Well-differentiated thyroid cancer (i.e. papillary microcarcinoma) may be r evealed by a clinically palpable cervical node, especially in young patient s, Primary tumor specificity (small-sized, superior location, invasion, mul tifocality) and characteristics of cervical node involvement (with synchron ous central and lateral multiple node spread) require appropriate treatment by a skilled surgeon. Contrary to the primary tumor treatment (total thyro idectomy), surgical management of the cervical node basins remains controve rsial. Only a special knowledge of the specificity of this disease and cerv ical lymphatic anatomy will ensure a good prognosis for the patient.
