Background Thyroid nodules are typically an initial sign of thyroid cancer (TC) and require evaluation by thyroid ultrasonography. Additional measures, such as fine needle aspiration, may be necessary depending on the level of malignancy risk. This study aims to comprehensively analyze TC clinical, radiological, and histopathological characteristics in a cohort of Saudi patients.

Background And Aims: Follicular-patterned thyroid tumors (FPTTs) are frequently encountered in thyroid pathology, encompassing follicular adenoma (FA), follicular thyroid carcinoma (FTC), noninvasive follicular thyroid neoplasm with papillary-like nuclear features (NIFTP), and follicular variant of papillary thyroid carcinoma (fvPTC). Recently, a distinct entity termed differentiated high-grade thyroid carcinoma has been described by the 5th edition of the WHO classification of the thyroid tumors, categorized as either high-grade fvPTC, high-grade FTC or high-grade oncocytic carcinoma of the thyroid (OCA). Accurate differentiation among these lesions, particular between the benign (FA), borderline (NIFTP) and malignant neoplasms (FTC and fvPTC), remains a challenge in both histopathological and cytological diagnoses.

Oncocytic adrenal cortical carcinoma (ACC) is a rare malignant adrenal cortical tumor with limited documented case reports. Herein, a 65-year-old female patient presented with a large, solid adrenal mass. A diagnosis of oncocytic ACC was rendered with the following tumor characteristics: The tumor entirely consists of diffuse sheets of polygonal cells with bizarre nuclear atypia and deeply eosinophilic cytoplasm.

Article Synopsis
- * Key mutations were identified in various genes, such as APC and TP53, with significant genomic alterations including a unique RAD51 biallelic deleterious translocation linked to homologous recombination deficiency.
- * The research also found no major differences in mutation load or genetic features between traditional and oncocytic ACC subtypes, revealing a broad range of genomic changes that may help guide future cancer treatment options.
