title: Ultrasound biomicroscopic appearances of eyelid lesions at 50 MHz.
abstract: OBJECTIVE
  To correlate the ultrasound biomicroscopy (UBM) appearance of eyelid lesions with the results of histopathologic examination.
  
  
  METHODS
  Fifty-two patients with eyelid lesions were evaluated using 50-MHz UBM, and the UBM scans were compared with the histopathologic findings. The obscuration of the normal lid sonographic layers and invasion into adjacent tissues were criteria suggesting malignancy.
  
  
  RESULTS
  UBM characteristics of different eyelid lesions are presented. The sensitivity of UBM in detecting malignancy ranged from 78% to 86%, whereas the specificity ranged from 37% to 69%.
  
  
  CONCLUSIONS
  This study of eyelid lesions shows that UBM can help differentiate between various benign and malignant lid lesions.
