title: Adrenocortical oncocytoma in pregnancy.
abstract: BACKGROUND
  Adrenal oncocytomas are uncommon, nonfunctioning tumors occurring most often in endocrine organs.
  
  
  METHODS
  A 32-year-old woman presented at 25 weeks' gestation complaining of right flank pain. Abdominal ultrasonography and computed tomography revealed a 9 x 10-cm solid right-sided adrenal mass. Endocrine evaluation was normal. At 36 weeks' gestation, she underwent cesarean followed by resection of the adrenal mass. Histopathologic and ultrastructural studies revealed a benign adrenocortical oncocytoma.
  
  
  CONCLUSIONS
  Although rare, adrenocortical oncocytomas should be included in the differential diagnosis of solid, nonfunctioning, adrenal tumors in pregnancy.
