A male-specific increase in the HLA-DRB4 (DR53) frequency in high-risk and relapsed childhood ALL

Previous studies reported significant HLA-DR associations with various leukemias one of which is with HLA-DRB4 (DR53) family in male patients with childhood ALL. We have HLA-DR-typed 212 high-risk or relapsed patients with childhood (n = 114) and adult (n = 98) ALL and a total of 250 healthy controls (118 children, 132 adult) by PCR-SSP analysis. The members of the HLA-DRB3 (DR52) family were underrepresented in patients most significantly for HLA-DRB1*12 (P = 0.0007) and HLA-DRB1*13 (P = 0.0001). In childhood ALL, the protective effect of DRB3 was evident in homozygous form (P = 0.001). The DRB4 marker frequency was increased in males with childhood ALL (67.4%) compared to age- and sex-matched controls (42.1%, P = 0.003) and female patients (35.7%, P = 0.004). Besides being a general marker for increased susceptibility to childhood ALL in males, HLA-DRB4 is over-represented in high-risk patients. These results further suggest that the HLA system is one of the components of genetic susceptibility to leukemia but mainly in childhood and in boys only. (C) 2002 Elsevier Science Ltd.

Unusual Clinical Presentation of Hodgkin Lymphoma in a Child

Background: Hodgkin lymphoma (HL) is predominantly a nodal disease with extranodal presentation being uncommon. Presentation with neurological symptoms is not uncommon in adult patients with HL. Subdiaphragmatic involvements are less common especially in childhood. In the literature, there has been no case which presented with both spinal cord compression and bilateral hydronephrosis in pediatric patients with HL. Observation: We report a 9-year-old boy diagnosed with HL who presented with bilateral hydronephrosis and epidural involvement. Conclusion: Differential diagnosis of abdominal mass in patients presenting with spinal cord compression and/or hydronephrosis should include HL. Retrograde J ureteral stenting is the treatment of choice for malignant ureteral obstruction
