Metastasis to the primary thyroid carcinoma is extremely rare. We report here a case of colonic adenocarcinoma metastasis to medullary thyroid carcinoma in a 53-yr old man with a history of colon cancer. He showed a nodular lesion, suggesting malignancy in the thyroid gland, in a follow-up examination after colon cancer surgery. Fine needle aspiration biopsy (FNAB) of the thyroid gland showed t...

Thyroid nodules are common and are being more commonly identified with improvement in imaging modalities. Because thyroid nodules are frequently found incidentally during routine physical examination or imaging performed for another reason, physicians from a diverse range of specialties encounter thyroid nodules. Clinical decision making depends on proper evaluation of the thyroid nodule. Diagn...

Dual malignancy was first reported by Billroth in 1889. Incidence of second malignancy in cancer patients is as high as 10%, but synchronous anaplastic thyroid cancer along with breast tumor is a rare entity. We present a case of a 61-year-old female with a synchronous anaplastic carcinoma thyroid with ductal carcinoma breast. The plausible association of breast cancers with thyroid carcinomas ...

Primary squamous cell carcinoma of the thyroid gland (PSCCT) is a rare malignancy that presents with advanced disease and poor prognosis. It is difficult to diagnose PSCCT in its early stage because of its rarity and lack of typical imaging findings. We experienced an elderly woman with PSCCT confirmed by surgery. Although preoperative fine-needle aspiration revealed no malignancy, surgical res...

Thyroglossal duct cysts are the most frequently encountered congenital neck masses having a malignancy rate of 1%. The most common malignant form is papillary thyroid carcinoma. Synchronous papillary thyroid carcinoma developing in the thyroglossal duct cyst is rarely seen. Synchronized papillary carcinoma can be described as a multifocal tumor or a metastatic lesion on a thyroglossal duct cyst...

This study aims to look at the prevalence of thyroid malignancy in previously healthy children and adolescents presented with multinodular goiter (MNG) and or solitary nodules for which they underwent thyroid surgery. Twenty one children and adolescents (13 males and 8 females) underwent partial or total thyroidectomy over a 10-year period. Papillary thyroid carcinoma was found in 4 (19%) patie...

Introduction: Thyroid nodules are commonly encountered on ultrasonographic studies. Color doppler ultrasonography can be utilized to help in differentiating malignant and nonmalignant nodules based on different imaging criteria. Objective: The objective of this study is to correlate sonographic and color Doppler characteristics of thyroid nodules with the results of sonographically guided fine-...

BACKGROUND Thyroid nodules often discovered incidentally and present a management problem particularly when investigations suggest atypical or suspicious cells. Prediction of the risk of malignancy within such a thyroid nodule is based on clinical, biochemical, ultrasonographic, and cytologic features. Our aim was to create a nomogram to predict accurately the chance of malignancy within a thyr...

Colorectal cancer (CRC) metastasis to the thyroid gland is rare. Here wereport a 45 yr-old man in western Iran referred to Hematology Clinic, Kermanshah city, Iran in March 2014 with complaint of exertional dyspnea, multi-nodular goiter as well as complaint of exertional dyspnea, and multi-nodular goiter. His history included a low anterior resection of rectum in 9 months ago for a high-risk st...

BACKGROUND The Bethesda System for Reporting Thyroid Cytopathology (BSRTC) is used in surgical decision-making according to malignancy risk in each category. Malignancy risk in atypia/follicular lesion of undetermined significance (AUS/FLUS) is estimated in BSRTC to be 5% to 15%, but institutional data have varied widely. METHODS We conducted a post-BSRTC 4-year retrospective analysis of inde...
