Discordance in biochemistry and ultrasonography: Nonsecretory parathyroid adenoma

Dilek Dellal Fatma , Aydin Cevdet , Kilinc Ibrahim , Kilicarslan Aydan , Ersoy Reyhan , Cakir Bekir

Aim: Although nonsecretory parathyroid carcinoma is relatively more frequent, nonsecretory parathyroid adenoma was also reported. It is thought to precede functioning parathyroid adenoma.Case report: An iso-hypoechoic 6.5×9.5×16.1 mm thyroid nodule with irregular borders in the superior-posterior part of right thyroid lobe was observed in ultrasonography in a 44-year-old female euthyroid patient. Fine-needle aspiration (FNAB) biopsy resulted wi...

Are there any differences between demographic characteristics, preoperative ultrasonographic findings, and cytological results of patients with thyroid tumors of uncertain malignant potential and papillary thyroid carcinoma of classical and non-encapsulated follicular variants?

Introduction: Thyroid tumors of uncertain malignant potential (TT-UMP) has been accepted as a subgroup of follicular-patterned thyroid tumors for which benignancy or malignancy cannot be assessed exactly. We aimed to evaluate demographic characteristics, ultrasound (US) findings, and cytological results of patients with TT-UMP and compare these findings with the classical variant of papillary thyroid carcinoma (CV-PTC) and non-encapsulated follicular variant of PTC (NEFV-PTC) ...

Ultrasonographical, clinical and histopathological features of 1264 nodules with papillary thyroid carcinoma and microcarcinoma based on tumor size

Cuhaci Neslihan , Baser Husniye , Topaloglu Oya , Ozdemir Didem , Kilicarslan Aydan , Ersoy Reyhan , Cakir Bekir

Introduction: In recent years, due to the improvements in ultrasonography (US), it has become possible to gain more information about the papillary throid carcinoma (PTC) and papillary tyroid microcarcinoma (PTMC). However, whether PTC and PTMC exhibit the same ultrasonographic features and behave same features is controversial. We aimed to evaluate the patients diagnosed with PTC and PTMC in terms of clinical, ultrasonographical (US) and histopathological features and their r...

Ultrasonographical and cytological features of exophytic thyroid nodules: do exophytic nodules pretend to be malignant?

Dellal Fatma Dilek , Baser Husniye , Ozdemir Didem , Kilicarslan Aydan , Ersoy Reyhan , Cakir Bekir

Aim: Exophytic nodule refers to a nodule that sticks out of the normal thyroid boundary/outline. Other definition is a nodule with an acute angle between the lesion and adjacent thyroid capsule. In the literature, one study reported that thyroid nodules with exophytic configuration showed a high malignancy rate. We aimed to compare ultrasonographical features and cytopathologic results of exophytic and non-exophytic thyroid nodules.Material and method: T...

Coexistent toxic adenoma and Riedel thyroiditis: a case report

Tam Abbas Ali , Ozdemir Didem , Ersoy Pamir Eren , Kilicarslan Aydan , Ersoy Reyhan , Cakir Bekir

Riedel thyroiditis is a rare chronic inflammatory disease of the thyroid. It is characterized by replacement of normal parenchyma with dense fibrotic tissue. Peripheral tissues might also be affected and this may cause airway obstruction, dysphagia, recurrent laryngeal nerve palsy and hypoparathyroidism. We report a patient with toxic adenoma previously treated with radioactive iodine and histopathologically confirmed Riedel thyroiditis.Case: A 61 years ...

Does timing of repeat fine needle aspiration biopsy in thyroid nodules alter the adequate or AUS/FLUS cytology result?

Dilek Dellal Kahramanca Fatma , Sacikara Muhammed , Kilicarslan Aydan , Evranos Ogmen Berna , Aydin Cevdet , Topaloglu Oya , Ersoy Reyhan , Cakir Bekir

Aim: To determine whether early repeat fine needle aspiration biopsy(FNAB) has an effect on adequate or atypia of undetermined significance/follicular lesion of undetermined significance(AUS/FLUS) cytology rates in thyroid nodules with inadequate or AUS/FLUS in the first FNAB.Method: Nodules of patients who underwent repeat biopsy due to insufficient or AUS/FLUS cytology between 2019-2022 were included. Demographic data of the patients and ultrasonograph...

Comparison of clinicopathological features in patients with familial and sporadic papillary thyroid cancer

Dellal Fatma Dilek , Ozdemir Didem , Aydin Cevdet , Ogmen Berna , Kilicarslan Aydan , Kilic Mehmet , Ersoy Reyhan , Cakir Bekir

Introduction: Although, familial medullary thyroid cancer is a known condition, familial papillary thyroid cancer (PTC) is a rare and less well described clinical entity. While some studies suggest more aggressive features in familial PTC, some do not support these findings. We aimed to compare ultrasonographical, cytopathological and histopathological results of patients with familial and sporadic PTC.Methods: Data of 194 patients diagnosed with PTC his...

A cancer of undetermined significance – incidental thyroid carcinoma

Evranos Berna , Burcak Polat Sefika , Neslihan Cuhaci Fatma , Baser Husniye , Topaloglu Oya , Kilic Mehmet , Kilicarslan Aydan , Ersoy Reyhan , Cakir Bekir

Introduction: Incidental thyroid carcinoma (ITC) in patients operated on for a benign disease is frequent. ITC characteristics in patients operated for malign disease, but not sampled by fine needle aspiration (FNA) or seen in ultrasonography, is unknown. We aimed to compare ITC with nonincidental ITC (NITC) in this study.Material and method: Retrospective analyses of 918 individual patients who were operated for benign and malign thyroid disease in our ...

Malignancy risk and false negative rate of fine needle aspiration cytology in thyroid nodules equal or greater than 4 cm

Bestepe Nagihan , Ozdemir Didem , Ali Tam Abbas , Dellal Fatma Dilek , Kilicarslan Aydan , Parlak Omer , Ersoy Reyhan , Cakir Bekir

Background: We aimed to evaluate malignancy rate in thyroid nodules ≥4 cm and determine false negativity of fine needle aspiration biopsy (FNAB) in these nodules.Methods: Patients who underwent thyroidectomy between January 2007 and December 2014 in our institution were reviewed. Demographical and clinical data and preoperative ultrasonography (US) findings were obtained from the medical records. The nodules in these patients were grouped as &#8805...

Bethesda classification is highly predictive especially for the diagnoses of aggressive variants of papillary thyroid carcinoma

Evranos Berna , Polat Sefika Burcak , Baser Husniye , Ozdemir Didem , Kilicarslan Aydan , Yalcin Abdussamed , Ersoy Reyhan , Cakir Bekir

Background: Fine needle aspiration biopsy (FNAB) has proven to be the most valuable diagnostic procedure for preoperative discrimination of benign and malignant nodules. Bethesda System for Reporting Thyroid Cytopathology (TBSRTC) has standardized reporting and cytomorphological criteria in aspiration smears. In this study, we aimed to determine malignancy rates in nodules with different cytology results and diagnostic value of TBSRTC for variants of papillary thyroid carcinom...
