Abstrakt: Background: Large paraganglioma of the Zuckerkandl organ (POZ) is extremely rare. The patient can occasionally be paucisymptomatic, further obscuring the diagnosis and carrying high mortality. Recommended treatment for large paraganglioma (PGL) is open surgical removal. We report a case of successful laparoscopic resection of a large POZ with normal blood pressure in a 45-year-old man.
Case Presentation: A 45-year-old man was hospitalized because of hyperglycemia. Computed tomography of the abdomen and the serum and urinary catecholamine levels confirmed the diagnosis of large POZ. But his blood pressure was normal and he underwent laparoscopic tumor excision successfully. During 6 months follow-up after laparoscopy, serum and urinary catecholamines were normal but glycaemia remained high level. DNA analysis of the succinate dehydrogenase complex subunits B (SDHB) and SDHD revealed no mutation.
Conclusions: POZ is an unusual mass and preoperative diagnosis can be difficult in clinically silent cases. PGL cannot be excluded in patients with normal blood pressure. Even a large POZ can be excised laparoscopically by following proper techniques.
