Follicular carcinoma of the thyroid usually presents as nodules with rare cases showing metastasis at diagnosis. But occult follicular carcinoma without any thyroid enlargement and presenting as multiple lytic bone lesions is unusual and relatively rare. Here we report a 66-year old Malay man presenting with occipito-parietal swelling for last two years. He had no thyroid enlargement; no thyroi...

This is a retrospective case study of a 61-year-old woman diagnosed with follicular thyroid carcinoma. The patient underwent thyroidectomy for the treatment of goitre after being admitted for shortness of breath. Microscopic and immunohistochemical studies were performed, which confirmed follicular carcinoma of the thyroid with an insular component. We also conducted a review of the literature ...

The Bethesda System for Reporting Thyroid Cytology (TBSRTC) has proven to be an effective and robust thyroid fine needle aspiration (FNA) classification scheme to guide the clinical treatment of patients with thyroid nodules. However, a tendency of increasing diagnosis of atypia of undetermined significance/follicular lesion of undetermined significance (AUS/FLUS) is observed. This is commensur...

BACKGROUND Papillary thyroid carcinoma often has lymph node metastasis, compared with follicular thyroid carcinoma. The study showed that epithelial-mesenchymal transition occurs in carcinoma cells during the first stage of metastasis, where some extracellular matrix molecules are secreted in large quantities. Sialic acid carried by fibronectin as the antigen of the monoclonal antibody (MoAb) J...

A retrospective study was performed to determine the reliability of physical examination (PE), ultrasonography (US) and fine-needle aspiration cytology (FNA) in the evaluation of thyroid nodules. Preoperative diagnoses of 252 euthyroid patients comprised 126 with benign lesions, 114 with papillary carcinoma and 12 with follicular carcinoma made by PE, US and FNA were reviewed. The specificity o...

BACKGROUND Thyroid cancers are the most frequently occurring endocrine malignancy worldwide. In Turkey, thyroid cancers are ranked 2(nd) on the incidence list in women, with a rate of 16.2%, but they are not included among the top 10 cancer types in men. AIMS To identify the contribution of the BRAF(V600E) mutation, and the RET/PTC1 and PAX8-PPARγ rearrangements in the diagnosis and different...

BACKGROUND The catalytic component of telomerase, human telomerase reverse transcriptase (hTERT) has been found to be reactivated in immortalized cell lines and considered as a diagnostic marker for malignancy in different body tissues. AIM OF WORK Therefore we thought to determine whether hTERT gene detection could serve as an adjunct in the diagnosis of thyroid lesions together with evaluat...

BACKGROUND The diagnosis of thyroid follicular carcinoma by fine needle aspiration biopsy is a well known problem in thyroid pathology. METHODS We evaluated telomerase activity (TA) in 85 fine needle aspiration biopsy (FNAB) samples from patients with thyroid nodules. Surgery samples from patients with tumor or follicular adenomas were also analyzed. RESULTS Twenty of the FNAB samples corre...

Introduction Follicular thyroid cancer, similar to follicular adenoma, usually takes the form of a round, encapsulated tumour. Cytological examination does not allow a firm diagnosis of follicular thyroid cancer to be made. Follicular thyroid cancer can be diagnosed by histopathological examination only after demonstrating the infiltration of the capsule by the tumour and/or vessel invasion. Th...

A 50-year-old woman presented with an extremely uncommon case of solitary metastasis from follicular carcinoma of the thyroid, which presented clinically as trigeminal neurinoma. Neuroimaging detected a tumor in the right petrous apex, which was removed surgically. Histological examination showed metastatic follicular carcinoma of the thyroid. However, no primary tumor was detected by various i...
