Neuroblastoma presenting with the nephrotic syndrome.

A case of neuroblastoma in a 4-yr-old boy presenting with the nephrotic syndrome is reported. Nether thrombosis nor stenosis of the renal veins and the inferior vena cava was present. Electron microscopy revealed lumps of subepithelial deposits as well as thickening and tortuosity of the glomerular basement membrane compatible with membranous nephropathy. It is postulated that deposition of neuroblastoma-associated immune complexes on the glomerular basement membrane-was responsible for the development of the nephrotic syndrome in this patient. Five pediatric cases of nephrotic syndrome associated with extrarenal neoplasia were collected from the world literature and are briefly discussed.

Use of technetium-99m as a radioactive label to study migratory patterns of leukocytes.

Technetium-99m had been used as a radioactive label to study the migratory patterns of neutrophils. In a previous in vitro study, neutrophils were labeled with Tc-99m and infused into patients with and without various hematological disorders. Increased pulmonary localization was detected by scintillation camera within 10 min; this decreased gradually within 3 hr. Accumulation was seen in the liver and spleen at 3 hr. The same results were noted by using neutrophils labeled with Tc-99m sulfur colloid. In a patient with severe ulceration in the oral cavity, due to acute leukemia, Tc-99m-labeled transfused neutrophils that were collected by filtration leukopheresis were concentrated in the infected lesions.
