Recurring desmoid tumor of the neck: A case report.

The infiltrative growth pattern of desmoid tumors and their proximity to important anatomical structures make them difficult to manage. Mutilating surgery should be avoided, while surveillance or radiotherapy remain valid options.

SPORADIC MEDULLARY THYROID CARCINOMA IN GRAVES' DISEASE.

Introduction: Graves' disease (GD) and concomitant thyroid nodules can be found in up to 44% of all cases, of which up to 17% are determined as malignant tumors. Medullary thyroid carcinoma (MTC) seems to be found extremely rarely, which causes belated diagnosis.

Case Presentation: A 50-year-old man was diagnosed with GD.

Challenging diagnosis of cervical vagal nerve schwannoma.

Schwannoma arising from vagal nerve is a rare tumour. It is a slow-growing, benign mass, but rarely it might undergo malignant transformation. We report a case of a 55-year-old woman with asymptomatic Xth cranial nerve schwannoma in the left side of the neck.

Papillary Thyroid Carcinoma Tissue miR-146b, -21, -221, -222, -181b Expression in Relation with Clinicopathological Features.

We analyzed miR-146b, miR-21, miR-221, miR-21, and miR-181b in formalin fixed paraffin-embedded papillary thyroid carcinoma (PTC) tissue samples of 312 individuals and evaluated their expression relationship with clinicopathological parameters. A higher expression of miR-21 was related to unifocal lesions ( < 0.011) and autoimmune thyroiditis (0.

Different stability of miRNAs and endogenous control genes in archival specimens of papillary thyroid carcinoma.

Background: The most popular miRNA quantitation technique is RQ-PCR with relative gene expression method that requires an endogenous control (EC) gene for data normalization. However, there are insufficient data and selection criteria on the most suitable ECs for miRNA expression studies in many cancer types including papillary thyroid carcinoma (PTC). Therefore, in this study we evaluated the impact of chosen EC and archival formalin-fixed, paraffin-embedded (FFPE) PTC tissue age on estimated target miRNA expression.
