The classic triad of pheochromocytoma symptoms of headache, sweating and tachycardia is not present in a high percentage of patients and is sometimes diagnosed as incidentaloma or atypical presentations.Case report: The authors present a 56-year-old man, with no known diseases, referred to Endocrinology evaluation by incidentaloma of the right adrenal gland, from the Pne...

Introduction: Secondary causes of diabetes refer to a category in which diabetes is associated with other diseases. They are thought to constitute less than 2% of the total cases of diabetes.Case report: A 56 year-old caucasian man, with no relevant medical history, presented to the Emergency Department with fatigue, polyuria, polydipsia, polyphagia and involuntary weight loss (6 kg in two weeks).

Introduction: The endocrine system is often affected in the course of HIV infection. However, hypopituitarism and diabetes insipidus are uncommon disorders in these patients and have been related to drugs, infections of the central nervous system and neoplastic infiltration, in extremely rare cases.Case report: We present a case of a 42-year-old man with HIV infection known since 2005, but undergoing antiretroviral therapy only since 2010 (emtricitabine/...

Introduction: Leiomyomas are benign tumors originating from the smooth muscle cells. They occur more frequently in the uterus and in the gastrointestinal system. Adrenal leiomyomas are rare tumors arising from the smooth muscle of the adrenal vein and its tributaries.Case report: Man, 72-years-old, referred to Endocrinology in the context of an adrenal incidentaloma (20 mm maximum diametre) detected in abdominal-pelvic CT performed for the study of splen...

Introduction: Central diabetes insipidus (CDI) is a rare complication of acute myeloid leukemia (AML) occurring in less than 0.6% of patients. It is associated with genetic changes in chromosomes 3 and 7. CDI may precede; occur simultaneously or after the diagnosis of AML.Case report: 51-year-old man, with no relevant past medical history, began complaining with polyuria, polydipsia, weakness and weight loss in March 2015.The patient was evaluated in the...

Introduction: Mauriac Syndrome is characterized by the presence of hepatomegaly, growth retardation, delayed puberty and cushingoid features. This entity is traditionally diagnosed during the work-up of hepatic enzymes alterations in children/young adults with type 1 diabetes mellitus (T1DM) with poor glycaemic control. However, the impact of metabolic control in the normalization of hepatic analytic profile is not clarified.Methods and design: Retrospec...

Introduction: Propylthiouracil is a drug used in the treatment of hyperthyroidism and autoimmunity phenomena have been described as a side effect of its use. Despite anti-neutrophil cytoplasmic antibodies (anca) positivity is frequent in patients treated with propylthiouracil, the occurrence of clinically evident vasculitis is rare.Case report: A 65-year-old woman, diagnosed with hyperthyroidism 2 years ago and treated with propylthiouracil (50+...

Introduction: Bilateral macronodular adrenal hyperplasia is a rare cause of Cushing’s syndrome (CS) characterized by multiple adrenal nodules >1 cm. It can be diagnosed in patients with overt CS but is more often diagnosed incidentally, especially in the 5th or 6th decades of life.Clinical case: 61-year-old woman with type 2 diabetes, arterial hypertension and dyslipidemia treated with metformin+sitagliptin 1000/50 mg bid, valsartan+hydrochlorot...

Introduction: Primary acinic cell carcinoma (ACC) is an uncommon salivary gland (SG) tumor, making up 1–3% of all SG neoplasms, more frequent in women, at 40–60 year old. The cause is still unknown and the only well-established risk factor is ionizing radiation. ACC metastasize in 10–15% of the cases, 35% tends to recur and the rate of disease-associated death is about 16%. Surgical resection is the mainstay treatment, but radiation therapy may be used in some c...

Introduction: Pheochromocytomas and extra-adrenal paragangliomas are rare neuroendocrine tumors, with a peak incidence between the 3rd–5th decades of life and about 10% are malignant. Although they have the same radiographic and histologic characteristics of their benign counterpart, malignant pheochromocytomas are diagnosed by the presence of local invasion or metastatic tumor in the non-chromaffin tissues, and offer a poorer prognosis. Treatment is typically extirpative...
