[Isolated cystic cervical lymphatic metastasis from occult papillary carcinoma of the thyroid: unusual and rather difficult diagnosis].
Thyroid papillary carcinoma, exceptionally, can appear with cervico-lateral metastases in absence of thyroid evident disease. In that case we can have an infected branchial cyst, therefore is very important a correct preoperative diagnosis with FNAB. In literature were described 30 cases of cervico-lateral cystic masses that the histology revealed as occult papillary carcinoma metastases. Our experience is about 80 cases of papillary carcinoma, in only 2 cases the cancer was evident as a tight-elastic tumour in cervico-lateral region, hypoechogenic to the US scan with irregular and thick wall: one of the patient had multinodular goiter; the other one didn't have clinical of US scan character of thyroid disease. FNAB on lymph nodes shows doubtful cells evidence. Both patient had a total thyroidectomy with functional cervico-lateral and MAS lymphadenectomy. In one patient histology showed a papillary carcinoma of 4 mm in the right lobe, in the other patient the cancer was unknown. FNAB, in all doubtful cases, is the most important diagnosis test.
