Background: When surgeons decide to perform lobectomy as the treatment of papillary thyroid carcinomas (PTCs), they must consider the possibility of contralateral cancer. We wanted to determine the incidence of bilateral PTCs (bPTCs) and analyze their characteristics. We also wanted to determine how many patients with bPTC were missed preoperatively.
Methods: From January 2007 to May 2011, a total of 466 patients with PTC who were treated by total thyroidectomy at a single institution were enrolled. Patients were divided into two groups based on bilaterality. The patients with bPTCs were further investigated regarding the preoperative presence of the contralateral tumor.
Results: Bilaterality was seen in 29.8 % of PTC patients. In all, 36.8 % of PTCs ≥ 1 cm, and 25.7 % were papillary thyroid microcarcinomas (PTMCs). The presence of PTC in the contralateral lobe was missed in 15.8 % of bPTCs and in 21.3 % of bPTMCs. The rates of preoperatively nondetected contralateral cancer were 4.7 and 5.5 % for PTCs and PTMCs, respectively. Tumor size and multifocality were factors associated with bilaterality (p = 0.014 and p < 0.001, respectively).
Conclusions: Bilaterality is found more frequently when the tumor is large. Multifocality also can help predict the possibility of bilaterality. Therefore, total thyroidectomy may be necessary for patients with a multifocal or large tumor. It should be noted that the presence of a contralateral cancer is missed in 4.7 and 5.5 % of patients with preoperatively diagnosed unilateral PTC and PTMC, respectively.

Introduction Thyroid malignancy remains a significant global health concern, making the accurate differentiation between benign and malignant thyroid nodules crucial for optimal patient management. Fine-needle aspiration cytology (FNAC) is the gold-standard preoperative diagnostic tool, and The Bethesda System for Reporting Thyroid Cytopathology provides a standardized framework for interpretation. This 10-year retrospective study evaluated the malignancy risk in surgically treated patients with thyroid nodules classified as Bethesda Category III by comparing FNAC findings with histopathological outcomes.

Papillary thyroid cancer (PTC) is the most frequent thyroid malignancy. Recently, the incidence has become widespread among both male and female individuals worldwide. In this article, we aim to report a 32-year-old Saudi female who presented with a painless lateral neck mass for more than seven months, and on excisional biopsy, was found to have features of PTC.

Background: Multifocality is a distinctive feature of papillary thyroid carcinoma (PTC); however, the biological behavior of PTC and its optimal management strategy remain unclear. The aim of this study was to analyze the clinical features and prognostic differences of multifocal papillary carcinoma and to guide the precise treatment of multifocal papillary carcinoma.
Methods: The medical records of 1,139 patients with PTC who had undergone total or hemi-thyroidectomy between April and October 2013 at the Tianjin Medical University Cancer Institute and Hospital were reviewed.
