Differentiated thyroid cancer in patients taking lithium for bipolar affective disorder: a case series

Ali Tam Abbas , Aydin Cevdet , Ozdemir Didem , Bilginer Muhammed Cuneyt , Ersoy Reyhan , Cakir Bekir

Aim: Lithium bicarbonate is a drug used in the initial treatment of bipolar disorders. Lithium is an element of alcali metal group and besides being a causative agent for goiter and hypothyroidism primarily, it has also some antithyroid effects. Rarely, lithium may cause hyperthyroidism secondary to thyroiditis or probably autoimmune mechanisms. The association between lithium and thyroid cancer is very little known subject. In this case series, we presented differentiated thy...

Evaluation of preoperative ultrasonographic and biochemical features of patients with aggressive parathyroid disease: Is there any reliable predictive marker?

Cakir Bekir , Burcak Polat Sefika , Kilic Mehmet , Ozdemir Didem , Aydin Cevdet , Sungu Nuran , Ersoy Reyhan

Introduction: Parathyroid cancer (PC) is rare accounting for <1% of all presentations. Tumors that demonstrate these atypical features and do not fulfill criteria for carcinoma can be classified as atypical adenomas (APA). Herein we aimed to evaluate the clinical and biochemical features of the patients with an atypical parathyroid adenoma or carcinoma and compare it with benign parathyroid adenomas.Method: Twenty-eight patients who were operated for...

Bilateral large adrenal lesions in a patient with undertreated congenital adrenal hyperplasia

Bilginer Muhammet Cuneyt , Ozdemir Didem , Aydin Cevdet , Ersoy Reyhan , Cakir Bekir

Introduction: Congenital adrenal hyperplasia (CAH) is a group of autosomal recessive diseases characterized by enzyme deficiencies in cortisol secretion. The most common form is 21-alpha hydroxylase deficiency. Here, we report a patient with undertreated CAH and bilateral large adrenal masses.Case report: 34 years old male patient diagnosed with CAH and testicular anorchia at the age of 7 admitted to our clinic for general weakness. Hydrocortisone treatm...

Evaluation of TSH receptor antibodies and histopathological features in patients with toxic multinodular and toxic nodular goiter

Aydin Cevdet , Baser Husniye , Neslihan Cuhaci Fatma , Ozdemir Didem , Yalcin Samet , Ersoy Reyhan , Cakir Bekir

Introduction: Association between high thyrotrophin receptor antibodies (TRAb) and relapse of thyroid cancer in Graves’ patients was reported previously. In this study, we aimed to investigate possible relation between TRAb and thyroid malignancies in patients with toxic multinodular (TMNG) and toxic nodular goiter (TNG).Methods: Thyroidectomized patients with a preoperative diagnosis of TMNG, TNG and euthyroid multinodular or nodular goiter (MNG/NG...

Neck lesions located outside the thyroid bed with similar echogenity of thyroid tissue

Dellal Fatma Dilek , Aydin Cevdet , Ozdemir Didem , Ersoy Reyhan , Ocal Berrak G. , Cakir Bekir

Introduction: We aimed to determine demographical, hormonal, ultrasonography(US) and cytological features of cases with neck lesions that are located outside the thyroid region and have similar echogenity with thyroid tissue.Method: Neck US reports of patients who underwent fine needle aspiration(FNAB) under US guidance in our clinic in a period of one year were reviewed retrospectively. Lesions having similar echogenity with thyroid tissue and defined a...

Hemithyroidectomy seems to be a reasonable initial surgical approach for patients with cytologically Bethesda Category III (AUS/FLUS) thyroid nodules

Bilginer Cuneyt , Ozdemir Didem , Topaloglu Oya , Aydin Cevdet , Dumlu Gurkan , Dogan Hayriye , Ersoy Reyhan , Cakir Bekir

Introduction: Atypia of undetermined significance/follicular lesion of undetermined significance (AUS/FLUS) termed as Bethesda Category III constitute 15–30% of thyroid cytology. However, the risk of malignancy in this heterogenous category is estimated as 5–15%. The recent studies has been reported the malignancy rate in the wide range of 6–48%. This causes surgical approach variability between different centers. We aimed to evaluate the initial malignancy rate...

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...

Hyalinizing trabecular tumor of thyroid in a patient with suspicious for papillary cancer in fine needle aspiration biopsy: a case report

Tam Abbas Ali , Aydin Cevdet , Ozdemir Didem , Dogan Hayriye Tatli , Korukluoglu Birol , Ersoy Reyhan , Cakir Bekir

Introduction: Hyalinizing trabecular tumor is a very rare neoplasm of thyroid and can be misinterpreted as papillary or medullary cancer in fine needle aspiration biopsy (FNAB).Case report: Multinodular goiter was detected in a 65 years old woman using metformin and L-thyroxine for impaired blood glucose and Hashimoto thyroiditis, respectively. FNAB was performed in two nodules and reported as suspicious for malignancy and benign. She underwent total thy...

Evaluation of clinical and biochemical features of patients with atypical parathyroid adenoma: a retrospective study

Polat Sefika Burcak , Kilic Mehmet , Aydin Cevdet , Ozdemir Didem , Sungu Nuran , Ersoy Reyhan , Cakir Bekir

Introduction: Primary hyperparatyhyroidism (PHPT) is usually caused by single or multiple adenomas and cancer is rare accounting for <1% of all presentations. The presence of certain cytological and architectural features such as adherence to adjacent organs, a solid growth pattern, broad bands of fibrosis, cytological atypia, and an irregular growth contour do not indicate malignancy but are recognised as atypical features encountered more commonly in malignant than benig...

Ultrasonographical features and cytological findings of thyroid nodules in patients with Hashimoto's thyroiditis

Ozdemir Didem , Dellal Fatma Dilek , Baser Husniye , Yazgan Aylin Kilic , Turkolmez Seyda , Ersoy Reyhan , Cakir Bekir

Introduction: It is unclear whether ultrasonographic (US) findings and fine-needle aspiration biopsy (FNAB) results of nodules accompanied with Hashimoto’s thyroiditis (HT) are affected by the presence of thyroiditis or not. In this study, we compared US features and cytological results of nodules in patients with and without HT.Methods: Patients who underwent FNAB in our clinic were evaluated prospectively. Nodules in patients with and without HT w...
