    Composite Adrenal Pheochromocytoma-Ganglioneuroma in an Adult Patient

    Acta Endo (Buc) 2014 10(1): 140-149 doi: 10.4183/aeb.2014.140

    Background. Composite adrenal pheochromocytoma-ganglioneuromas (PHEO-GNs) are well-defined neoplasms of the adrenal medulla, consisting of both endocrine and neural components. They are extremely rare. To date, only 46 cases have been reported in the English literature. Case report. We describe an adult case of endocrinologically active adrenal composite PHEO-GN diagnosed in a 62-year-old male patient with history of dizziness, headache, nausea, vomiting, and uncontrolled hypertension including intermittant hypertension attacks. On physical examination, he had a blood pressure (BP) of 170/110 mmHg. 18-fluorodeoxyglucose positron emission tomography-computed tomography showed a right adrenal tumor with increased metabolic activity. Urinary levels of catecholamines and their metabolites were prominently elevated. Right adrenalectomy was performed for treatment purposes. The histological diagnosis of the resected tumor was composite adrenal PHEO-GN. Conclusions. Composite adrenal PHEO-GN is a rare entity and preoperative diagnosis is difficult. Its hormonal activity and imaging characteristics are frequently very similar to those of other adrenal tumors, especially pure PHEO and adrenal carcinoma. Therefore, careful evaluation by endocrine tests and multiple imaging procedures are needed for providing a differential diagnosis. However, definitive diagnosis composite adrenal PHEO-GN is established by histological and immunochemical studies. To our knowledge, the present case is the first report that describes composite adrenal PHEO-GN in a patient from Turkey. We discuss this case and review the literature on this unusual entity.

    Hypoparathyroidism, Deafness, and Renal Dysplasia

    Acta Endo (Buc) 2014 10(4): 687-692 doi: 10.4183/aeb.2014.687

    Background. HDR syndrome is an autosomal dominant disorder characterized by hypoparathyroidism, sensorineural deafness, and renal dysplasia caused by mutation of the GATA3 gene. Case report. We describe a case of HDR syndrome diagnosed in a 46-yearold male patient. He had hand numbness, intermittent dizziness, and imbalance due to hypocalcemia. Physical examination was slim in appearance, had marfanoid features, and presented the typical apathetic face. He had a narrow rib cage and pectus excavatum deformity. Laboratory findings included serum calcium of 7.4 mg/dL, phosphorus of 4.87 mg/dL, albumin of 4.5 g/dL, intact parathormone (iPTH) of 13.3 pg/mL, 25(OH) D3 vitamin of 16.3 μg/L, daily urinary calcium excretion of 23.4 mg/day. Noncontrast computerized tomography (CT) of the brain showed bilateral basal ganglia calcification. Abdominal ultrasonography and CT showed the absence of renal tissue in the left kidney site and pelvis (left renal aplasia). Audiometry revealed mild sensorineural hearing loss at high frequencies. Conclusions. The patients with HDR syndrome are often diagnosed when they are examined for symptomatic hypoparathyroidism and deafness. To the best our knowledge, the present case is the second case of Barakat Syndrome reported from Turkey. The treatment of HDR syndrome is focused on clinical symptoms. The prognosis of the disease correlates with hypoparathyroidism and the severity of renal disease. HDR syndrome has an autosomaldominant inheritance, screening of family members is recommended for early diagnosis and treatment.
