Metachronous Bilateral Adrenal Neuroblastoma: A Case Report and Literature Review.

A baby presented with a large right adrenal mass, multiple hepatic lesions and diffuse bone marrow infiltration when she was just over 1 month old. After needle biopsy and a histologic definition of neuroblastoma, she underwent chemotherapy and a subsequent complete resection. Three years after diagnosis, a large left adrenal localized mass was detected.

Neuroblastic tumors and neurofibromatosis type 1: A retrospective multicenter study in Italy and systematic review of the literature.

Background: Neuroblastic tumors (NBTs) are the most common extra-cranial solid tumors of childhood. Neurofibromatosis type 1 (NF1) is the most common neurocutaneous disorder with a predisposition to tumors. The co-occurrence of NBTs in the setting of NF1 has been occasionally reported, suggesting a non-casual association and likely configuring a spectrum of neural crest-derived disorders.

Dramatic response to Cisplatin window therapy in a boy with advanced metastatic ewing sarcoma.

Ewing sarcoma (ES) is the second most common type of primary bone malignancy, and retains a high propensity to metastasize; the prognosis of patients with disseminated disease is very poor, with an event-free survival rate of <20%. Current multimodality treatment for ES consists of combined chemotherapy before and concurrent with surgery and local radiotherapy for the involved bone. Cisplatin is one of the most widely used drugs for the treatment of bone tumors in children, but is not currently used in ES.

Vocal cord palsy after vincristine treatment in a child and the inefficacy of glutamic acid in the prevention of relapse: a case report.

Introduction: Vincristine is an antineoplastic drug with a well known efficacy for the treatment of acute lymphoblastic leukemia and many solid tumors. No more than 20 pediatric patients with vincristine-induced vocal cord palsy have been reported, and to the best of our knowledge this is the first case where glutamic acid was administered with the aim of preventing a relapse of laryngeal dysfunction.

Case Presentation: The larynx paralysis presented with hoarseness and stridor in a Caucasian 18-month-old girl and spontaneously resolved in about a month.

Effectiveness of cyclosporine and mycophenolate mofetil in a child with refractory evans syndrome.

Evans Syndrome is a rare autoimmune disease consisting of hemolytic anemia, thrombocytopenia and/or neutropenia. It may be associated with other autoimmune or lymphoproliferative diseases. Its course can be extremely serious and, rarely, even life-threatening; thus it represents a excellent treatment challenge for the pediatric hematologist.

Simultaneous diagnosis of acute lymphoblastic leukemia and peripheral neuroblastic tumor in a child.

We report the case of a 3-year-old girl with a mediastinal mass, severe anemia, leukocytosis and neutropenia, in whom, after initial suspicion of metastatic neuroblastoma, a final diagnosis of concurrent ganglioneuroblastoma and acute lymphoblastic leukemia was made. The mediastinal tumor was surgically excised and the child subsequently underwent chemotherapy for acute lymphoblastic leukemia. The patient remains in complete remission from both diseases 4 years after the diagnosis and 24 months after completion of all treatment.

Hepatopathy-thrombocytopenia syndrome (HTS) after actinomycin-D therapy: report of three cases and review of the literature.

Hepatopathy-thrombocytopenia syndrome (HTS) is a severe complication very similar to vein occlusive disease (VOD), also known as hepatic sinusoidal obstructive syndrome (SOS), characterized by fever, hepatopathy (hepatomegaly with abnormal liver function tests), ascites, weight gain, jaundice, and thrombocytopenia (platelet count less than 25 × 10(3)/μL). It has been generally observed in patients with Wilms tumor, and is commonly associated to administration of actinomycin D. We report three children with Wilms tumor, with severe HTS/SOS, but had a different outcome, in spite of vigorous supportive therapy.

Hodgkin lymphoma and nephrotic syndrome in childhood.

An association between nephrotic syndrome and extrarenal neoplasia was described for the first time in 1922. Since then a large number of cases have been published, few of them describing the link between Hodgkin disease (HD) and nephrotic syndrome (NS). It shows that the incidence of nephrotic syndrome in Hodgkin lymphoma is less than 1%.

Severe polyuria and polydipsia in hyponatremic-hypertensive syndrome associated with Wilms tumor.

The combination of hyponatremia and renovascular hypertension is known as hyponatremic-hypertensive syndrome (HHS) and so rarely described in children but associated with various kinds of occlusions of the renal artery. We describe two children who presented HHS with severe hypokalemia, polyuria, and polydipsia associated with Wilms tumor, which required treatment with an angiotensin-converting enzyme inhibitor before nephrectomy. All HHS signs and symptoms resolved only following surgical resection of the tumor, allowing chemotherapy to be given.

Focal nodular hyperplasia of the liver: an unusual association with diabetes mellitus in a child and review of literature.

Hepatic hemangioma, adenoma and focal nodular hyperplasia are the most frequent benign lesions of the liver, but they are all infrequent among pediatric population. The reports of focal nodular hyperplasia in children have recently increased in number, with many cases associated to drug intake, particularly to chemotherapy. We here describe, to our knowledge, the first case of focal nodular hyperplasia in association with diabetes mellitus in childhood.

Reversible posterior leukoencephalopathy syndrome: report of 2 simultaneous cases in children.

Reversible posterior leukoencephalopathy syndrome (RPLS) is a rare complication of cancer chemotherapy. We have recently observed two cases occurred simultaneously in children receiving different chemotherapy regimens, for hepatoblastoma and acute lymphoblastic leukaemia, respectively. Both children presented with altered mental status, severe visual disturbances, headache, seizures, backpain and hypertension.

Congenital hepatic fibrosis: a very uncommon cause of pancytopenia in children.

The disease presentation of autosomal recessive polycystic kidney disease (OMIM #263200, ARPKD) is highly variable and includes polycystic kidneys, pulmonary hypoplasia, and congenital hepatic fibrosis. The authors report an unusual case of ARPKD presenting with hepatosplenomegaly and cytopenia mimicking acute leukemia.
