title: Presentation and therapy of myelolipoma.
abstract: BACKGROUND
  Adrenal myelolipoma is a rare and benign, hormonally inactive tumor frequently discovered incidentally. Because of the increasing rate of detection of adrenal myelolipoma, use of the correct diagnostic examination and treatment, with respect to surgical excision or regular controls, is continually gaining importance. We report herein on the largest series of surgically treated patients with adrenal myelolipoma from a single institute.
  
  
  METHODS
  The clinical charts of 12 patients who underwent adrenal surgery for myelolipoma were reviewed. Follow up was carried out by means of re-examination or by personal contact with the primary physician. It was possible to perform a re-examination on eight of the 12 patients 6.9 years after the operation: one patient had died 5.2 years after surgery.
  
  
  RESULTS
  Diagnosis of adrenal myelolipoma was made incidentally in seven patients, and during examination for reasons of unspecific abdominal or flank pain in five patients. A transabdominal approach was taken in five patients, a subcostal approach was taken in three patients and a translumbal approach was taken in four patients. At the follow up, all formerly symptomatic patients were free of symptoms. No recurrence could be seen; however, in one patient a contralateral adrenal myelolipoma had developed.
  
  
  CONCLUSIONS
  Symptomatic tumors, growing tumors or tumors larger than 10 cm should be excised surgically by means of an endoscopic or conventional approach, depending on the size. Surgical indication should not be liberalized by the introduction of more gentle operative techniques such as the translumbal or the endoscopic approach. A close follow up should be maintained in the case of patients free of symptoms, and for those with a definite diagnosis from imaging procedures.
