✦ Synopsis
Background. Cervical cystic lymph node metastases as first and sole manifestation of occult papillary thyroid carcinoma are observed exceptionally rarely. In the seven patients here reported, a cystic, ovoid mass in the lateral aspect of the neck was the initial symptom of the papillary microcarcinoma.
Methods. There were six men and one woman, aged between 17 and 54 years (mean 31.7 years), who complained of round, movable, painless masses in the lateral aspect of the neck. Two patients were first seen with two cervical tumors. Tumors had been present from a few days to 12 months (mean 5.1 months). The cystic nature of tumors was demonstrated by echographic studies. In all cases, thyroid tumors were not palpable on physical examination and no abnormalities of the thyroid gland were shown by other diagnostic procedures.
Results. The diagnosis was made preoperatively by fineneedle aspiration cytology of the nodes in five of the seven cases. All patients underwent thyroidectomy with conservative neck dissection followed by radioactive iodine therapy. After a follow-up period from 1 to 7 years, all patients are alive with no apparent signs of recurrence or metastasis.
Conclusions. In a young patient with solitary lateral cervical cyst, the diagnosis of lymph node metastasis from occult papillary thyroid carcinoma should be considered. Any lateral mass requires tissue diagnosis, and fine-needle aspiration is usually ad-equate for clarification of the histology. Ipsilateral modified neck dissection and total thyroidectomy followed by radioactive iodine therapy offers a favorable prognosis.
