A case of perirenal neuroblastoma causing intrarenal obstruction of the pelvis of the kidney presented as a small hydronephrosis at 3 days of age. The tumor grew rapidly over the next 48 hr, diagnosis was confirmed by ultrasonography, and the mass was removed surgically.

A 26-year-old woman had a neuroblastoma during infancy; an extra-adrenal pheochromocytoma at age 16 years, with hepatic recurrences during the next ten years; and multifocal renal cell carcinoma. Neuroblastoma and pheochromocytoma, despite their common embryologic origin, to our knowledge have not been previously reported as separate tumors in the same patient. Although many attributes of the patient's tumors suggest a hereditary disorder, thorough investigation disclosed no evidence of heritable conditions associated with any of these tumors in the patient or her family members. Long-term observation of persons surviving after treatment of neuroblastoma will be necessary to determine whether this case represents a previously unidentified tumor predisposition or a sporadic occurrence.

The case of a 2 1/2-year-old girl with a well-nigh asymptomatic neuroblastoma of the left adrenal is described. In the final stage it gave rise to unusual clinical signs. The tumor had grown into the inferior vena cava via the left suprarenal and renal veins. Dissolution of the soft tumor mass in the vena cava caused fatal massive embolism of lungs and brain.

The diagnosis of bilateral neuroblastoma in the adrenal glands in a newborn led to the discovery of a family with clustering of tumors of neural crest origin. According to the two-mutation model of neuroblastoma development we searched for individuals with the first mutation, who are predisposed to neuroblastoma. Neither chromosomal analysis of the peripheral blood nor the examination of catecholamines nor of gm-phenotypes could mark the first step to neuroblastoma. However, it was possible to detect cystationinuria in familial neuroblastoma for the first time. Cystationinuria could be calssified as secondary to vitamin B6-deficiency. Since cystathioninuria and vitamin B6-deficiency were not only seen in blood-relations but also in relatives by marriage there was no fixed correlation to individuals with tumor or their relatives.

Thirteen children with localized (Evans stage I or II) thoracic primary neuroblastoma were divided into two groups according to the type of therapy administered, in order to compare the therapeutic efficacy and morbidity of excisional surgery followed by either irradiation alone or irradiation plus chemotherapy (group A) with similar surgery alone (group B). Group A consisted of 6 children (mean age 1 year, 2 months). Complete surgical excision was accomplished in 2 patients, while 4 had microscopic residual. All 6 patients are free of disease at 26--76 months (mean 47 months), including 2 who had recurrent tumor and received additional therapy. Two have developed congestive heart failure and one severe scoliosis secondary to irradiation. Of the 7 children in group B (mean age 2 years, 2 months), 3 had microscopic residual tumor and 2 had adjacent lymph node involvement. After 12--47 months (mean 23 months), no recurrence or surgery-related morbidity has been observed. From these limited data it appears that surgery alone may provide adequate therapy for localized thoracic neuroblastoma and obviate the morbidity associated with multimodal therapy.

An intravenous urogram in a child with left adrenal neuroblastoma and bone metastases deomonstrated malrotation of the left kidney but no visible mass. A bone scan showed uptake of 99mTc by the tumor which suggested the diagnosis, confirmed by an abdominal echogram.

A child with mediastinal and supraclavicular ganglioneuroma, heterochromia iridis, and Horner's syndrome is described. The authors postulate that the thoracic neoplasm originated as a congenital neuroblastoma with metastasis to the supraclavicular lymph nodes and subsequent benign transformation, and that the ocular abnormalities resulted from sympathetic ganglion injury by the tumor in infancy. This seems to be the first published report of such ocular abnormalities associated with mediastinal ganglioneuroma.

A case of extracranial metastasis of cerebral neuroblastoma without previous craniotomy is presented. The tumor in the left posterior frontal region penetrated the dura mater and the skull, formed a lump under the galea and metastasized to the lymph nodes in the infraparotid and superior cervical regions.

A light- and electron-microscopic review of 40 cases diagnosed at Children's Hospital of Pittsburgh as ganglioneuroblastoma, neuroblastoma, or small round cell tumor-probably neuroblastoma disclosed four cases that contained abundant glycogen. Two were unquestionable neuroblastomas by electron microscopy; one was primary in the adrenal gland, the other in the mediastinum. In the third case, a paraspinal tumor, the light-microscopic appearance was suggestive or neuroblastoma, but no catecholamine granules or neural processes were demonstrated in the material available for electron microscopy. The fourth case was an undifferentiated malignant tumor in the pectoralis muscle of a 12-year-old girl. By electron microscopy, neural processes were demonstrated and the tumor was classified as peripheral neuroblastoma. Of the remaining 36 cases, electron microscopy readily indicated a diagnosis of neuroblastoma or glangioneuroblastoma in 35 of them. In the other case, the tissue had been fixed in formalin and only a few catecholamine granules were found after an extensive search.

The hematologic manifestations of neuroblastoma are numerous and varied. Bone marrow invasion by tumor cells may cause leukoerythroblastic changes or depression of one or more of the cell lines in the peripheral blood; occasionally bone marrow involvement may be so extensive that tumor cells may be released into the peripheral blood and lead to an erroneous diagnosis of leukemia. Anemia in neuroblastoma patients may result not only from bone marrow involvement, but also from bleeding into a tumor mass or from the hemolysis accompanying a consumption coagulopathy. A specific morphologic abnormality, the cogwheel erythrocyte, has been reported in patients with neuroblastoma. Neuroblastoma may also be associated with elevation of the platelet count or a hypercoagulable state. Recognition of these protean hematologic manifestations may facilitate diagnosis in children with atypical presentations of this highly malignant tumor.
