Insulin-mediated pseudoacromegaly with nonfunctioning pituitary adenoma

Celik Mehmet , Ayturk Semra , Yilmaz Bulbul Buket , Guldiken Sibel

Pseudoacromegaly is a rare disorder characterized by cutaneous manifestations of growth hormone excess but with normal growth hormone levels or IGF-1. This condition described in patients with insulin resistance, hypothyroidism, pachydermoperiostitis and drug intake such as minoxidil. The hyperinsulinaemia impaired metabolic signalling may activate intact mitogenic signalling pathways and stimulate pathological tissue growth.A 41-year-old man presented w...

Submandibular ectopic thyroid with normally located thyroid gland

Yilmaz Mahmut Sinan , Ayturk Semra , Guven Mehmet , Dilek Fatma Husniye

Ectopic thyroid is a rare developmental anomaly of the thyroid gland which is defined as the presence of thyroid tissue at a site other than the pretracheal area. Nearly 1–3% of all ectopic thyroids are located in the lateral neck. Simultaneous submandibular ectopic thyroid tissue presenting with a functional orthotopic thyroid gland is extremely rare. A 37-year-old woman was admitted to our outpatient clinic with a cervical mass existing for 3 years. On physical examinat...

Case with metastatic lung cancer who developed adrenal insufficiency

Bulbul Buket Yilmaz , Celik Ece , Celik Mehmet , Ayturk Semra , Ustun Funda , Guldiken Sibel

Adrenal metastasis is common (35%) among the patients with lung cancer, while less than 3% of the patients develop bilateral adrenal metastasis. Adrenal metastases are generally small and clinically asymptomatic. Adrenal insufficiency is rare despite the presence of adrenal metastasis. Lam et al. reported this ratio as 0.7%. We aimed to present a case with lung cancer and bilateral adrenal metastasis who developed adrenal insufficiency.A 63-year old male...

A rare case: adrenal lymphangioma

Durmus Yusuf , Celik Mehmet , Bulbul Buket Yilmaz , Ayturk Semra , Can Nuray , Tastekin Ebru , Guldiken Sibel

Adrenal lymphangioma is a rare benign tumors of the adrenal gland. Because of the increased use of imaging methods in recent times, the diagnosis is usually made incidentally. It is usually due to malformation between the lymphatic and the venous system. Those with small indiameters are generally asymptomatic and can be evacuated by needlea spiration. However, surgery is recommended for cysts over 6 cm in diameter due to risk of infection, bleeding, compression of neighboring ...

A rare case: non-islet cell tumor hypoglycemia with adrenal insufficiency

Asoglu Veysi , Celik Mehmet , Bulbul Buket Yilmaz , Ayturk Semra , Ustun Funda , Guldiken Sibel

Non-islet cell tumor hypoglycemia (NICTH) is a rare paraneoplastic syndrome and is the second most common cause of tumor-related hypoglycemia following insulinoma. Its prevalence is not known and is likely that many cases would go undiagnosed. In here, we describe a patient with PNET who presented with severe hypoglycemia.A 37-year-old male with known metastatic Pancreatic neuroendocrine tumors (PNET) presented with weight loss, sweating, and tremor, epi...

Insulin resistance and BRAFV600E mutation in the patients with differentiated thyroid carcinoma

Celik Mehmet , Yilmaz Bulbul Buket , Ayturk Semra , Tastekin Ebru , Can Nuray , Sezer Atakan , Ustun Funda

Aim: The incidence of nodular thyroid disease is high among patients with insulin resistance. The aim of this study is to evaluate the relationship between BRAFV600E mutation and insulin resistance in the patients with papillary thyroid cancer.Materials and methods: We examined clinical and laboratory data of 103 patients who had been followed up by our department between the years 2010 and 2015. The diagnosis of insulin resistance (IR) was made when the...

A rare cause of respiratory failure: Anaplastic carcinoma

Celik Ece , Celik Mehmet , Bulbul Buket Yilmaz , Ayturk Semra , Can Nuray , Serez Bilkay , Guldiken Sibel

Anaplastic thyroid carcinoma (ATC) is one of the most aggressive and lethal human malignancies. The median survival time following diagnosis is typically six months or less. Rapidly growing tumors may cause respiratory failure by compressing trachea. A 71-year-old woman presented with 1-month history of dyspnea, cyanosis and rapidly enlarging neck mass for the past 2 weeks. She had been suffering from multinodular goiter disease. Physical examination revealed a large, fixed an...

Clinical characteristics of Paget disease of bone from Turkey

Yavuz Dilek Gogas , Ayturk Semra , Bayraktar Firat , Cetinkalp Sevki , PD Study Group

Prevalence of Paget’s disease (PD) of bone as well as clinical and demographical presentation may differ between the populations.Aim: In this study we evaluate clinical and demographical parameters of Paget’s disease patients followed from endocrinology clinics in Turkey.Method: An invitation was sent to all tertiary endocrinology clinics to complete a survey on demographic clinical, laboratory parameters, treatment modal...

Pituitary apoplexy case caused by Hanta virus ınfection

Ayturk Semra , Genc Ahmet Bilal , Yaylaci Selcuk , Karabay Oguz , Tamer Ali , Celik Mehmet

Pituitary apoplexy (PA) is a rare but life-threatening medical emergency. Common predisposing factors include closed head trauma, blood pressure alterations, history of pituitary irradiation, cardiac surgery, anticoagulation, treatment with dopamine agonists, pituitary stimulation testing, and pregnancy. Hantaviruses belonging to the Bunyaviridae family are a group of rodent- or insectivore-borne single-strand ribonucleic acid (RNA) viruses. In humans, hantaviruses can cause h...

Four osteopoikilosis cases detected in a family

Ayturk Semra , Genc Ahmet Bilal , Yaylaci Selcuk , Gul Serdar Savas , Tamer Ali , Celik Mehmet

Osteopoikilosis (OPK) is a rare benign sclerotic bone dysplasia. It is inherited in an autosomal dominant pattern. There is no exact evidence of its aetiology and pathogenesis. Usually, it is an asymptomatic disease and the diagnosis is made incidentally from radiographs which show multiple, small, well-defined, variably shaped and widely distributed sclerotic areas over the skeleton. We report a family with OPK. A 22 years old woman was admitted to outpatient clinic with comp...
