Other nuclear features seen include nuclear pseudoinclusion and nuclear groove in coffee-bean shaped nuclei. 2 Usually children present with large tumors and lymph node metastases in up to 90 of the cases but the prognosis is generally good3 4 Interest in pediatric thyroid cancer has increased mainly after the Chernobyl nuclear power plant accident. DTC can present with a papillary pattern or a follicular pattern resulting in a diagnosis of either papillary carcinoma or follicular carcinoma.

Papillary thyroid cancer or papillary thyroid carcinoma is the most common type of thyroid cancer representing 75 percent to 85 percent of all thyroid cancer cases.
Papillary carcinoma occurred in all age groups although the inci- dence rose with increasing age in women. While papillary thyroid carcinoma tends to have an excellent prognosis certain histologic variants have been shown to have more aggressive clinical courses. When DM occur in primary thyroid carcinoma with low-risk histology they are almost always found at presentation.
Most tumors are heterogeneous with both histologiespapillary and follicular which is why they were formerly referred to as mixed papillary and follicular carcinomas.
