摘要: Context: Mutations of the gene encoding succinate dehydrogenase subunit B (SDHB) predispose to malignant paraganglioma (PGL). Recognition SDHB phenotype in apparently sporadic PGL directs appropriate treatment and family screening. Objective: The objective study was assess mutation-specific clinical biochemical characteristics SDHB-related PGL. Design: design retrospective descriptive. Patients: Patients included 29 patients (16 males) with abdominal or thoracic Intervention: There no intervention. Main Outcome Measures: Clinical presentations, plasma urine concentrations catecholamines O-methylated metabolites, genotype-phenotype correlations were measured. Results: Mean ± sd age at diagnosis 33.7 15.7 yr. Tumor-related pain among presenting symptoms 54% sole symptom 14%. Seventy-six percent had hypertension, 90% lacked a history All primary tumors but one originated f...
