IntroductionGlucagonoma is an extremely rare type of functional pancreatic neuroendocrine tumor that is characterized by distinctive clinical manifestations such as diabetes mellitus, weight loss, deep vein thrombosis, and necrolytic migratory erythema which represents the hallmark clinical sign of glucagonoma syndrome. Here, we report the case of a 53-year-old male patient who presented with high amilase and lipase levels. In further investigation a pan...

PurposePoorly differentiated thyroid carcinoma (PDTC); is a rare type of thyroid cancer with a high risk of recurrence, metastasis, and death. Pleural effusion due to thyroid cancer has seldom been reported. In this report, we present a case with PDTC related malignant pleural effusion.CaseA 66-year-old male patient presented with neck swelling and shortness of breath. At another center, thyroid ultrasonograp...

IntroductionThyroid cancer is the most common endocrine malignancy and its overall incidence has increased significantly in the last 30 years. Cancer in adolescents and young adults (AYA) is defined by the National Cancer Institute as diagnoses occurring among those aged 15 to 39 years. Thyroid cancer is the second most common cancer in the AYA population. In this study, we aimed to compare clinical, ultrasonographical, cytological and histopathological ...

IntroductionExtramedullary plasmacytoma (EMP) is a plasma cell neoplasm of extraosseous tissues. Less than 5% of all plasma cell neoplasms develop extramedullary. EMP is most common in the upper respiratory tract and oral cavity. The thyroid gland is one of the extremely rare regions. It is more common in men and the average age at diagnosis is 55. Primary thyroid plasmacytoma is one of the rare thyroid neoplasms. It often manifests as a rapidly growing ...

IntroductionIt is recommended to determine levothyroxine (LT4) dose individually in patients with hypothyroidism. However, higher doses of LT4 therapy are required to achieve target TSH levels in significant number of patients. Oral LT4 absorption occurs in the small intestine, especially in the jejunum and proximal ileum, while a small amount is absorbed in duodenum. Causes of LT4 malabsorption include helicobacter pylori infection, chronic atrophic gas...

The co-occurrence of congenital adrenal hyperplasia and type 1 diabetes mellitus (T1DM) is a rare phenomenon in existing literature. The primary cause of congenital adrenal hyperplasia (CAH) is often 21-hydroxylase deficiency (21OHD), a condition associated with the CYP21A2 gene located on chromosome 6p21.3 within the major human leukocyte antigen (HLA) histocompatibility locus. Various gene polymorphisms, particularly in HLA-DQalpha, DQbeta, and DR genes on chromosome 6p21.32...

Aim: In patients with papillary thyroid carcinoma (PTC), the incidence of subacute thyroiditis (SAT) is thought to be more frequent than estimated. The incidence of thyroid cancer is between 2.3% and 21.1% in Graves’ Disease (GD).Case: A 31-year-old female patient applied with complaints of amenorrhea and hair loss in the 10th postpartum month. There was no history of COVID-19 infection, but Biontech vaccine were administered two years ago. Her fami...

Introduction: Goiter means that the thyroid gland is larger than the normal size for the patient’s age and gender. Some of the causes of goiter are iodine deficiency, thyroid nodules, Graves’ disease(GD). Goiter, hyperthyroidism, ophthalmopathy and dermopathy can be seen in GD. Compression symptoms due to goiter (dyspnea, dysphagia, superior vena cava syndrome) are also seen. Here, we will present a case of GD with superior vena cava syndrome.C...

Introduction: The risk of malignancy in thyroid nodules is reported by the Bethesda system by performing fine needle aspiration biopsy (FNAB). Atypia of undetermined significance(AUS) or follicular lesion of undetermined significance(FLUS)(Bethesda 3) and suspicious for a follicular neoplasm (Bethesda 4) create uncertainty about treatment and follow-up. Molecular tests, ultrasonographic features of the nodules, and calcitonin level help us for this uncertainty. Here, we will p...

Aim: To determine whether there is any factor that can predict sufficient results in second thyroid fine-needle aspiration biopsy (FNAB) after first nondiagnostic cytological result.Materials and method: Nodules with non-diagnostic result after first FNAB were included and separated into two groups as sufficient (Group-1) and insufficient (Group-2) second FNAB. Results: Second FNAB was performed on 643 nodules of 443 patients with ...
