Abstract

The definition of papillary microcarcinoma (PMC) by the WHO is papillary thyroid carcinoma (PTC) measuring 10 mm or less regardless of extension to adjacent organs (Ex), clinical lymph node metastasis (N), and distant metastasis (M). Low-risk PMC is defined as PMC without Ex, N, or M. Recent development of imaging techniques, especially ultrasound examination, has enabled us to detect small nodules measuring 3 mm or less. Additionally, ultrasound-guided fine needle aspiration cytology (FNAC) facilitated diagnosis of small nodules detected by ultrasound. Because of the prevalence of these techniques, PMC has been very frequently detected and diagnosed. Largely due to these developments, the incidence of thyroid cancer, especially of small PTC, is increasing globally without an increase in thyroid cancer mortality.
