Rathke cleft cysts (RCCs) are non-neoplastic sellar lesions derived from remnants of Rathke’s pouch, and mostly asymptomatic. Symptomatic RCCs occur usually in middle-age, are >1 cm, and cause pituitary hypofunction, diabetes insipidus, hyperprolactinemia or visual impairment. In children, RCCs are rare and usually asymptomatic. However, symptomatic cases may present with growth retardation and diabetes insipidus. We report two children with symptomatic RCC manifestin...

In insulin resistant, young women with PCOS elevated serum AGEs and their receptor RAGE have been reported. The present study (approved by the local ethical committee) was undertaken to determine whether increased levels of serum AGEs in PCOS is a distinct finding compared with age- and BMI-matched women, presenting the isolated components of the syndrome and whether serum AGE levels were different among PCOS phenotypes. A total of 193 lean non-insulin resistant women were stu...

Introduction: Ganglioneuromas are rare, benign tumors of mature ganglion cells, arising from the sympathetic ganglia and 20% are located in the adrenal medulla, representing 1–4% of adrenal incidentalomas. About 1/3 secrete catecholamines but hypertension and other adrenergic symptoms are rare. About 60% are depicted with 131I- MIBG.Case report: A 72-year-old man was admitted for a left adrenal tumor 9×8 cm, incidentally found in abd...

Introduction: There is no concensus whether euthyroid children with Hashimoto’s thyroiditis (HT) need treatment with thyroxine.Aim of the study: To assess whether thyroxine influences goitre progression (calculated thyroid volume on U/S scan) in euthyroid children with HT.Subjects and methods: We studied 50 euthyroid children with HT for a 2-year period. Children with a multinodular goitre were not included in the study. Twent...

Pheochromocytomas and paragangliomas, tumors originating from the chromaffin cells, are rare in children.We report an 8-year-old boy who was admitted to the intensive care unit with seizures for which the child had to be intubated, severe hypokalemia (1.8 mEq/l), hyponatremia (127 mEq/l) and fever. Parents reported that several months before admission the boy had nocturnal sweating. Brain MRI revealed areas of increased sign intensity in the parietal lob...

Introduction: Monomorphic epitheliotropic intestinal T-cell lymphoma (MEITL), formerly known as type II enteropathy-associated T-cell lymphoma, is a rare and aggressive subtype of lymphoma of the gastrointestinal track typically noted in Asian or Hispanic populations. Adrenal involvement as part of MEITL is extremely rare. Herein we present a patient of Greek origin with MEITL and bilateral adrenal metastases.Case Presentation: A 74-year-old man presente...

Bariatric surgery is a common treatment for morbidly obese patients requiring weight loss and/or metabolic control. Vitamin D (VitD) deficiency and bone loss may occur post-operatively and supplementation with high oral doses of Vitamin D is required. Alternatively, intramuscular depot ergocalciferol (vitamin D2) which slowly releases VitD and overcomes the gastrointestinal tract, could be administrated in such patients.Aim: To present a case of severe V...

Introduction: 21-hydroxylase deficiency (21-OHD) is a common inherited disorder accounting for 90–95% of congenital adrenal hyperplasia (CAH) cases. Some cases may be diagnosed in adulthood after the incidental discovery of adrenal masses on computerized tomography (CT).Case report: A 59-year-old male was investigated for incidentally discovered bilateral adrenal masses in an abdomen CT scan, measuring 5 cm on the right and 8 cm on the left adrenal....

Background and objectives: Medullary thyroid carcinoma (MTC) originates from thyroid C-cells and is a calcitonin (CT) secreting tumour with aggressive behaviour. Surgery is recommended in all patients with basal or calcium-stimulated CT values of 100 pg/ml or higher due to the high probability of MTC. The objective of this study was to investigate the utility of calcium stimulation test for CT in order to distinguish MTC from C-cell Hyperplasia (CCH) preoperatively and to exam...

Introduction: Diagnostic and post-therapy radioiodine whole body scan (WBS) is used in the follow-up of differentiated thyroid carcinoma (DTC) for the detection of local recurrence or remote metastasis. We report a case of false-positive uptake of radioiodine WBS.Case report: A 37-year-old female patient underwent subtotal thyroidectomy for multinodular goitre and histology revealed multifocal papillary thyroid carcinoma, of follicular type with three fo...
