Severe aplastic anemia in a patient with primary immunodeficiency

This paper reports the case of a 6 year old boy with primary immunodeficiency disease, whose marrow cells showed dyshematopoietic features, that was subsequently transformed to severe aplastic anemia. He was first diagnosed as having congenital immunodeficiency comprising deficiency of immunoglobulin A (IgA), IgG2 and IgG4, depressed mitogen responses, lymphopenia with inverted CD4/CD8 ratio and an increased proportion of T-cell receptor gamma/delta-bearing cells. Cytogenetic study of the peripheral blood showed a normal karyotype of 46,XY, but that of the marked hypoplastic marrow demonstrated one cell with monosomy 7 and another with trisomy 8 in the 20 cells examined.

A case of cerebral glioblastoma with extensive cerebrospinal fluid dissemination: diagnostic value of immunohistochemical examination and MR imaging

A 9-year, 6-month-old boy presented with peripheral-type multiple cranial nerve palsy due to extensive cerebrospinal fluid (CSF) dissemination of intracranial glioblastoma multiforme. Tissue obtained from biopsy did not stain for glial fibrillary acidic protein (GFAP). The relationship between GFAP-negative tumor cells and extensive CSF dissemination agreed with recent reports. Magnetic resonance imaging with gadolinium-DPTA enhancement clearly depicted not only the cranial meningeal dissemination but also spinal metastasis. Magnetic resonance imaging showed undoubted usefulness in demonstrating disseminated glioblastoma.
