Massive infantile nephroblastomatosis: a clinical, radiological, and pathological analysis of four cases.

Four cases of massive infantile nephroblastomatosis with up to three and one-half years follow-up are described. Great similarity was found clinically, radiologically and pathologically, which distinguishes this entity from true Wilms' tumor. The course of the renal lesion following treatment was monitored by sequential radiological and biopsy studies. The pathogenesis, natural history, and management are discussed.

Report of a case of gross thymic hyperplasia in a child.

A large thoracic mass and a mediastinal lymph node were excised from an infant with a peripheral blood and bone marrow lymphocytosis. The 224-mass was composed of histologically normal thymus, and the lymph node architecture was partially effaced. Hypogammaglobulinemia was detected two years after thymectomy. The enormous thumus in this case fits the classic gross pathologic definition of hyperplasia. The possibility of associated thymic hyperfunction in this case is discussed.

Acute renal failure secondary to acute pyelonephritis.

A six year-old girl presented with acute oliguric renal failure, secondary to acute, non-obstructive pyelonephritis. Evidence for pyelonephritis as the cause of renal failure included: the evolution of typical changes on serial intravenous pyelograms, an acute interstitial inflammatory exudate on percutaneous renal biopsy, and gram-positive cocci on gram stain of the biopsy tissue. Although a specific causative organism was not conclusively identified, enterococcus was isolated from the initial catheterized urine specimen. The patient recovered from the acute illness but was left with impaired renal function, hypertension, and cortical scarring. Acute, non-obstructive pyelonephritis can produce acute renal failure in children and must be considered in the differential diagnosis of this syndrome.

Thymoma in a 12-year-old boy.

A case of thymoma in a 12-year-old boy is presented. The patient had a history of thymic irradiation in infancy, and a family history of leukemia. The mass was readily resected and the patient is well 10 years later. The tumor contained an unusual admixture of normal thymic tissue with the neoplastic epithelial elements. This peculiar histologic pattern is discussed in relationship to the patient's age and history.

Perianal rhabdomyosarcoma in childhood.

The case of a child with a stage I perianal embryonal botryoid rhabdomyosarcoma is presented, with description of coordinated management utilizing local excision, irradiation, and cyclic chemotherapy resulting in a 3-year tumor-free survival. Previously reported pediatric cases are summarized.
