Introduction: Hyalinizing trabecular tumor (HTT) is an unusual thyroid neoplasm that was first described by Carney in 1987.Many cytological and histological features of such tumors may be mistaken for Papillary Thyroid Carcinoma (PTC) and Medullary Thyroid Carcinoma (MTC).This can lead to overtreatment like total thyroidectomy and lymph node dissection. Here, we present a rare case of hyalinizi...

We report a rare case of papillary thyroid carcinoma incidentally found within a branchial cleft cyst. Only four other cases have been described in the literature. A total thyroidectomy and selective neck dissection was performed, and no evidence of occult primary disease was found after review of fine sections. Branchial cleft cysts are the most common lateral neck masses. Ectopic thyroid tiss...

The aim of this study was to evaluate the accuracy of fine-needle aspiration (FNA) cytology and thyroid scintigraphy (TS) in patients with solitary thyroid nodules. We retrospectively reviewed a series of 657 consecutive patients (531 (80.8%) women and 126 (19.2%) men, median age 45 years, range 16-81 years) with solitary thyroid nodules. Prior to surgery, all patients underwent FNA cytology wh...

Background: The aim of this study was to understand any association between differentiated thyroid carcinoma (DTC) and Ile3434Thr XRCC7 gene polymorphism (GenBank accession number: rs7830743). DTC is the most prevalent thyroid neoplasm, which includes papillary and follicular cell carcinoma. XRCC7 gene encodes a protein that functions in non-homologous end joining DNA repair pathway. Non-synony...

Rationale: Ectopic thyroid is commonly found in the neck region. Intra-abdominal ectopic thyroid is extremely rare, with only 2 cases reported in the pancreatic region. Very few reports have described detailed imaging findings of intra-abdominal ectopic thyroid. Patientconcerns:A 73-year-old womanwith aggravated recurrent right upper quadrant pain was found to have a retroperitoneal mass at the...

BACKGROUND Thyroid metastases are clinically rare, and usually occur in patients with a history of prior malignancy and when there are metastases elsewhere. Metastases of pancreatic carcinoma to the thyroid are extremely rare, with only three cases reported in the literature. CASE PRESENTATION We report a patient who had a pancreatic carcinoma with metastasis to the thyroid as initial clinica...

BACKGROUND Ultrasonography (US) plays a crucial role in the diagnostic management of thyroid nodules, but its widespread use in clinical practice might generate heterogeneity in ultrasound reports. OBJECTIVES The aims of the study were to propose (a) a standardized lexicon for description of thyroid nodules in order to reduce US reports of interobserver variability and (b) a US classification...

INTRODUCTION Papillary carcinoma is the most common malignant thyroid neoplasm. The effect of the concurrent presence of Hashimoto's thyroiditis and papillary thyroid carcinoma remains controversial. OBJECTIVE To evaluate the association between Hashimoto's thyroiditis and clinicopathological parameters in thyroid papillary carcinoma cases, based on an historical institutional cohort analysis...

BACKGROUND Collision tumors of the thyroid are a rare pathology that present a diagnostic and treatment challenge. In this report, we present an interesting case and a review of the current literature as to inform management. METHODS AND RESULTS An 88-year-old woman presented with acute airway compromise and vocal cord paralysis. CT identified a thyroid mass and widespread metastasis. Histopa...

Renal carcinoma cell is responsible for 3e4% of all neoplasms and 80e85% of malignant tumors of the renal cortex. The most frequent histological subtypes are: clear cells (approximately 75%), papillaries (10%), chromophobes (5%), oncocytoma (8%), angiomyolipoma (<1%). Among the less common histological types are the medullary carcinomas (1%), collecting ducts (1%), Xp11 translocation (<1%) and ...
