of the thyroid--prognostic significance of lymph node metastasis and multifocality.
Background: A large proportion of the patients with papillary thyroid microcarcinoma
are young women.
Papillary thyroid microcarcinoma
: proposal of treatment based on histological prognostic factors evaluation.
The 3 patients with Graves disease all had papillary microcarcinoma
found incidentally on postoperative histology.
It can be classified into four categories: (1) thyroid carcinoma or microcarcinoma
as an incidental finding after total thyroidectomy for benign mass, (2) radiological incidental finding of thyroid carcinoma with positive FNA result, (3) apparent thyroid metastasis with primary tumor unidentified prior to final histological specimen, and (4) symptomatic ectopic thyroid tissue with apparent metastasis .

Carcinoma arising in thyroglossal duct remnants with cervical lymph node metastasis and microcarcinoma
in the thyroid.
Hay, of 535 patients with thyroid papillary microcarcinoma
, median tumor size was 8 mm in diameter.
Delay in intervention for low-risk papillary microcarcinoma
does not affect prognosis.
14 cases (35%) were of classical PTC, 4 cases (10%) of papillary microcarcinoma
, 6 cases (15%) of FVPTC, 1 case (2.5 %) of diffuse sclerosing variant of PTC, 5 cases (12.5%) of FC-MI, one case (2.5%) of FC-WI and 9 cases (22.5%) of cellular nodule.
Additionally, we found that five cases of papillary thyroid microcarcinoma
(PTMC) (7.9%) presented dedifferentiation in the thyroid (2/5, 40.0%) and lymph node (3/5, 60.0%), of which 2 cases (40.0%) were observed to be fatal (Table 6).
Second, histologically, the lymph nodes in our case did not exhibit extensive fibrosis or lymphocytic infiltrate as shown in two cases of papillary thyroid microcarcinoma
that regressed to less than 1.5 mm with metastasis to lymph nodes .
