HBOT significantly decreased ( <.05) the expression of the 1 mRNA gene and ICAM-1 serum level ( =.004). The number of HBOT sessions strongly correlated with ICAM-1 serum level ( =.043) but poorly correlated with 1 mRNA gene expression ( =.22). The expression of the gene, however, strongly correlated with ICAM-1 serum level ( =-0.988, <.001). HBOT can reduce thermal wound complications, length of stay in hospitals due to thermal burns, 1 mRNA gene expression, and ICAM-1 serum level. HBOT can reduce thermal wound complications, length of stay in hospitals due to thermal burns, ICAM-1 mRNA gene expression, and ICAM-1 serum level. and importance Retroperitoneal ganglioneuromas that cause lower back and leg pain are extremely rare and are often misdiagnosed. Surgical resection has excellent prognosis in long-term survival. We present an 80-year-old man with two-year worsening left lower back and leg pain. He was treated as presumed lumbar spine spondylosis with several courses of physical therapy together with medical treatment. An abdomen CT scan disclosed a tumour in the left retrorenal space. The tumour was resected and the histopathologic examination suggested a completely excised retroperitoneal ganglioneuroma. During one-year follow-up the patient is free of pain without any local recurrence. Retroperitoneal ganglioneuromas are rare benign tumors that originate from neural crest-derived cells of the paravertebral sympathetic plexus and sometimes from the adrenal medulla. They are usually asymptomatic and discovered on routine clinical examination or on autopsy. Occasionally they may show symptoms due to local pressure effect or rarely they are hormonally active and present with adrenergic symptoms. Complete resection of the tumor is important in order establish the final diagnosis and alleviate sy
