Abstract

Papillary thyroid carcinoma (PTC) is the most common thyroid cancer subtype and constitutes 80% of all thyroid malignancies. PTC lesions that are 1 cm or less in size are defined as “papillary thyroid microcarcinoma” (PTMC). The incidence of occult PTC cases detected on autopsy series is very high, ranging from 10 to 35%. With the increased use of diagnostic imaging modalities, the detection rate of thyroid cancer is increasing worldwide. Both PTC and PTMC have good prognosis. Due to indolent nature of the disease, especially in PTMC cases, both the extent of the initial surgery and the need for RAI treatment remain controversial.

In this section, two cases are presented. One of them is a PTC with lymph node metastases, and the other is a PTMC case with multifocal disease.
