Abstract:
Left renal and left adrenal masses were incidentally found by computerized tomography (CT) in a 56-year-old man who was admitted to our hospital for treatment of upper digestive tract hemorrhage. Apparently no clinical signs suggestive of Cushing's syndrome existed. The renal tumor was diagnosed as renal cell carcinoma based on the findings on enhanced CT. 131I-adosterol uptake in the examination of adrenal scintigraphy under dexamethasone suppression was definitely increased in the left adrenal gland, although hormonal examinations of serum and urine for adrenal functions were within the normal range. Plasma adrenocorticotropic hormone (ACTH) and serum cortisol were suppressed by administration of 2 mg dexamethasone for 2 days. The left kidney was radically removed by surgery together with the left adrenal gland. Histological diagnoses were left renal cell carcinoma and adrenocortical adenoma.

The kidneys are located in the retroperitoneal space on either side of the vertebral column, protected posteriorly by the 11th and 12th ribs. The right kidney sits slightly lower than the left owing to the presence of the liver...

The Retinoblastoma Gene
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...
