BACKGROUND The objective of the study was to report a rare case of primary neuroendocrine carcinoma of the right kidney in a 36 year old male. METHODS The patient was clinically assessed; CT and OctreoScan scintigraphy were performed and levels of 5-HIAA, vanillylmandelic acid and NSE were determined. The tumor and metastases were histologically and immunohistochemically examined. RESULTS T...

In 1957, Armstrong, McMillan and Shaw demonstrated a metabolite of epinephrine (E) and norepinephrine (NE) in normal human urine (2, 3). This substance, 3-methoxy,4-hydroxymandelic acid (VMA, for vanillylmandelic acid), was excreted in abnormally large amounts in three patients with pheochromocytomas (3). Recent studies of sympathomimetic amine metabolism (Figure 1) (4-7) suggested that the uri...

pheochromocytoma is a catecholamine‑producing tumor. there are a very few reported cases of clinical pheochromocytoma. here, we report a 27‑year‑old woman para 1 live 1 with chief complaint of headache, confusion, nausea, and vomiting 2 days after cesarean section. she was anxious and had palpitation. on physical examination, fever, tachycardia, tachypnea, high blood pressure, and right thyroid...

We have developed a simple and precise paper chromatographic method for the determination of 4-hydroxy-3-methoxymandelic acid (VMA) in urine. Concentrations of VMA in patients with neuroblastoma were increased in comparison to controls. The linearity was excellent in the concentration range tested. The within-assay coefficient of variation for control and patient urine was less than 2.2%. ...

Neonatal adrenal hemorrhage presenting as an abdominal mass in the newborn is not uncommon. However, judging the nature of a suprarenal mass is sometimes difficult, especially when the structure is more complex with unusual clinical course. We report a male newborn with neonatal adrenal hemorrhage presenting as a multiloculated cystic mass. The margins between the mass and left kidney were indi...

Pheochromocytoma associated with inferior vena cava (IVC) thrombosis is very rare. A 27-year-old female presented with right flank pain and hypertensive urgency. Contrast-enhanced CT abdomen and gadolinium-contrast MRI abdomen revealed right adrenal mass suspicious of malignancy with invasion and compression to the right IVC wall along with IVC thrombus extending from the level of renal veins t...
