title: The collection of five interesting cases of adrenal tumors from one medical center.
abstract: BACKGROUND
  Adrenal tumors are detected incidentally in 4 to 8% of patients in imaging studies. Adenomas, pheochromocytomas and adrenocortical carcinomas represent the most common tumors of the adrenal glands. Rarely are final histopathological reports are surprising.
  
  
  OBJECTIVE
  The aim of our study is a retrospective analysis of selected clinical characteristics and hormonal studies in five cases of rare adrenal tumors.
  
  
  METHODS
  We present five interesting cases of adrenal tumors: two medullary hyperplasia, one adenomatoid tumor, one hydatid cyst and a primary angiosarcoma of the adrenal gland. The final diagnosis was established by means of microscopic examination of the specimens.
  
  
  CONCLUSIONS
  The number of adrenal tumors was increased due to widespread use of imaging procedures. In patients without any known extra-adrenal malignancy most lesions are benign, non-hyper functioning adenomas. Adrenal tumors should be evaluated biochemically and radiologically.
