We report 6 affected males in a 5-generation family with x-linked Simpson-Golabi-Behmel (SGB) syndrome. All had pre- and postnatal overgrowth with 2 adult males attaining heights over 195 cm. Other features included "coarse" face with hypertelorism, broad nasal root, cleft palate, full lips with a midline groove of the lower lip, grooved tongue with tongue tie, prominent mandible, congenital heart defects, arrhythmias, supernumerary nipples, splenomegaly, large dysplastic kidneys, cryptorchidism, hypospadias, skeletal abnormalities and postaxial hexadactyly. All affected individuals were of normal intelligence. One boy died at age 19 months of a neuroblastoma. The putative origin of the gene in this family was the maternal great grandmother of the propositus. Eight carrier females, who showed varying manifestations of the gene, have been identified. Anthropometric analysis has identified preliminary characteristic craniofacial dimensions in this syndrome. Molecular studies have shown a maximal lod score of 2.81 with no recombinants observed for the SGB-DXYS68 pairing, mapping the disorder to Xqcen-Xq21.3.

We reviewed the Tumor Registry for 1981 at the Children's Hospital of Philadelphia to identify all the children with newly diagnosed cancer who were seen initially in the emergency department (ED). Of the 220 new patients listed, 16 (7.3%) sought initial care in the ED (1 per 4,500 ED visits). Seven had leukemia, five had non-CNS solid tumors (2 lymphoreticular, 1 Wilms', 1 neuroblastoma, and 1 ovarian), and four had CNS tumors. Among the children with leukemia, pallor (6) and decreased activity (4) were the most common complaints. Duration of symptoms ranged from 4 days to 3 weeks. Physical examination showed pallor (5), splenomegaly (4), fever (3), hepatomegaly (3), lymphadenopathy (3), and ecchymoses or petechiae (2). The complete blood count and peripheral smears were all abnormal. The five patients with non-CNS solid tumors had symptoms related to the location of their neoplasms. The patients with Wilms' tumor, neuroblastoma, and ovarian dysgerminoma had abdominal masses; the patient with lymphoma had a large, painful inguinal node; and the patient with histiocytosis X had an infiltrative rash, gingivitis, and pneumonitis. Of the four children with CNS tumors, three had headache, and one had an incidentally detected scotoma following head trauma. All four eventually had abnormal neurologic exams and computer tomographic scans, but two were discharged initially with psychiatric diagnoses. We conclude that cancer, although rare in children, occurs with greater relative frequency in the referral hospital ED than that predicted by published cancer rates from the referring hospital's ED.(ABSTRACT TRUNCATED AT 250 WORDS)

The authors describe a case of stage IV-S neuroblastoma in a boy forty days old with impressive enlargement of the liver whose left lobe was initially mistaken for splenomegaly. Regression was obtained without active treatment. Factors affecting the prognosis and treatment are briefly discussed. Is reported the association with persistent elevation of serum acid phosphatase.

An apparently normal 10-day-old girl had, since birth, a gray-white vascularized tumor in the inferior quadrants of the right anterior chamber. General physical examination revealed abdominal distension, hepatomegaly, splenomegaly, and a deeply located abdominal mass. Multiple subcutaneous nodules scattered all around the body's surface could be palpated. Surgical exploration confirmed the presence of a left adrenal neuroblastoma. Six months after a complete resection of the abdominal tumor and general radiotherapy and chemotherapy, the right anterior chamber mass regressed almost completely, leaving only a calcified residue. The child is living and well six years after the diagnosis of neuroblastoma. This is the first case known to us in the literature of a congenital anterior chamber metastasis, as well as the first case reported of an anterior segment metastasis from a neuroblastoma.

This study evaluates the clinical and laboratory data of children with secondary hemophagocytic lymphohistiocytosis (sHLH) related to malignancy. Charts of patients who met the diagnostic criteria for sHLH associated with malignancy between January 2000-2006 at six different hospitals in Turkey were reviewed retrospectively. The diagnosis of HLH had been established by bone marrow aspiration in 27 patients, cerebrospinal fluid and bone marrow aspiration in one patient and lung-liver biopsy in another. Twenty-nine children were diagnosed as having sHLH related to malignancy. Twenty cases (18 ALL and 2 AML) with acute leukemia (10 girls/10 boys, median age: 8 years [3-14 years]) were found to have sHLH. Five patients with acute leukemia had HLH at the time of diagnosis (Group 1a), and 15 patients with acute leukemia were diagnosed as having sHLH during therapy (Group 1b), namely reactive sHLH associated with the chemotherapy. Nine patients, including two cases each of rhabdomyosarcoma, neuroblastoma, Hodgkin disease, and non-Hodgkin lymphoma (NHL) and one case with Langerhans cell histiocytosis, were diagnosed as having concomitant hemophagocytosis at the initial evaluation of the tumor (Group 2). Fever, anemia, and hypertriglyceridemia were present in all sHLH cases of all three groups. Hepatomegaly was detected in 60.0%, 73.3%, and 88.8% of the three groups, respectively. Splenomegaly was more frequent in patients of Groups 1a (60.0%) and 2 (88.8%) than in those of Group 1b, the reactive ones (13.3%). Hypofibrinogenemia was detected in all patients of Group 1a and Group 2. Low level of fibrinogen was present in 91.6% of patients in Group 1b. All patients in Group 1b (100%) had neutropenia and thrombocytopenia. Neutropenia was found at rates of 60.0% and 55.5% in Group 1a and Group 2, respectively. Thrombocytopenia was detected in 80.0% of patients in Group 1a and 77.7% in Group 2. The overall mortality rate was 34.4% (10 cases) in our series of 29 children with sHLH; 50% of deaths were directly attributable to HLH. Pediatric malignancy-associated HLH patients have been commonly described as case presentations or in a review of the literature. We believe that our cohort, compiling 29 children regarding the association between malignancy and HLH, will be useful for pediatricians who are interested in this still mysterious topic.

Galectin-1 (Gal-1) has been described to promote tumor growth by inducing angiogenesis and to contribute to tumor immune escape by promoting apoptosis of activated T cells. We had previously identified upregulation of Gal-1 in preclinical models of aggressive neuroblastoma (NB), a solid tumor of childhood. However, the clinical and biological relevance of Gal-1 in this tumor entity is unclear. Here, the effect of Gal-1 on the immune system and tumorigenesis was assessed using modulation of Gal-1 expression in immune effector cells and in a transgenic NB model, designated TH-MYCN. The fraction of CD4(+) T cells was decreased in tumor-bearing TH-MYCN mice compared to tumor-free littermates, while both CD4(+) T cells as well as CD8(+) T cells were less activated, compatible with a reduced immune response in tumor-bearing mice. Tumor incidence was not significantly altered by decreasing Gal-1/LGALS1 gene dosage in TH-MYCN mice, but TH-MYCN/Gal-1(-/-) double transgenic mice displayed impaired tumor angiogenesis, splenomegaly, and impaired T cell tumor-infiltration with no differences in T cell activation and apoptosis rate. Additionally, a lower migratory capacity of Gal-1 deficient CD4(+) T cells toward tumor cells was observed in vitro. Transplantation of TH-MYCN-derived tumor cells into syngeneic mice resulted in significantly reduced tumor growth and elevated immune cell infiltration when Gal-1 was downregulated by shRNA. We therefore conclude that T cell-derived Gal-1 mediates T cell tumor-infiltration, whereas NB-derived Gal-1 promotes tumor growth. This opposing effect of Gal-1 in NB should be considered in therapeutic targeting strategies, as currently being developed for other tumor entities.

Gaucher disease (GD) patients have an increased risk of cancer, in particular of hematological origin, while the association between GD and Neuroblastoma (NBL) has never been described. Here we report the case of an adolescent diagnosed with NBL, also presenting splenomegaly and persistent thrombocytopenia. The association with GD, suggested by the histological findings on bone marrow biopsy, was confirmed by enzymatic and genetic tests. The possible pathogenetic mechanisms are briefly reviewed. The evidence of this new association supports the necessity of further studies on GD comorbidities and the need of systematic data collection and analysis, potentially through an international registry. A greater attention for GD in the hemato-oncological field is needed, in order to avoid underdiagnosis and to optimize treatment strategies.
