Some medical defi nitions remain the same for many years, others change due to the progress in the diagnostic tools, which are able to distinguish markers and symptoms until then undetectable. Occult thyroid carcinoma is a general term indicating clinically different situations, whereas the incidentally detected papillary thyroid microcarcinoma is the most important from the clinical point of v...

Papillary microcarcinoma (PMC) is a thyroid tumor measuring 10mm or less in maximum diameter and comprise up to 30% of all papillary thyroid cancers. Most of them are detected incidentally and defined as incidental papillary microcarcinoma (IPC<or=10mm). The incidence of such incidental cancers found in surgical specimens of benign thyroid diseases is high. Although most PMC are incidental, all...

CONTEXT An activating mutation in the gene BRAF has been correlated with poorer prognosis and more aggressive clinical course in papillary thyroid carcinoma (PTC). We therefore hypothesized that the good prognosis, high 5-year disease-free rate and high survival rate of patients with less aggressive papillary thyroid microcarcinoma (pT1aNo-x) would be associated with a lower incidence of the BR...

Background: Active surveillance (AS) has become an alternative treatment approach for papillary thyroid microcarcinoma (PTMC). The purpose of this study is to uncover the clinicopathological factors associated with high-risk nodal disease in order select proper candidates AS PTMC.

Distant metastasis from papillary thyroid carcinoma (PTC), particularly from papillary thyroid microcarcinoma, is rare. We present a case of perigastric lymph node metastasis from PTC in a patient with early gastric cancer and breast cancer. During post-surgical follow-up for breast cancer, a 56-year-old woman was diagnosed incidentally with early gastric cancer and synchronous left thyroid can...

This is a case report on papillary thyroglossal duct cyst (TGDC) carcinoma along with synchronous occult papillary thyroid microcarcinoma. A 46-year-old woman visited our hospital because she had an anterior midline neck mass below her hyoid bone. Preoperative ultrasound-guided fine-needle aspiration cytology revealed signs of papillary TGDC carcinoma. We performed a Sistrunk operation and a to...

BACKGROUND The reported incidence rate of occult thyroid carcinoma in patients operated for benign thyroid pathology has been much higher than expected in the last years,especially for multinodular goitre, which raises the question about which should the proper surgical management for these cases be. AIM To assess the incidence rate of OTC in a single medium volume surgical center and to esta...

In Korea, the incidence of thyroid cancer increased explosively in the early 2000s, and reached a plateau in the early 2010s. Most cases of newly diagnosed thyroid cancer are small indolent microcarcinoma and could be good candidates for active surveillance (AS) instead of immediate surgery. Many considerations must be taken into account for establishing selection criteria for candidates for AS...
