title: Evaluation of aspiration cytology of ovarian masses with histopathological correlation.
abstract: OBJECTIVE
  To evaluate the efficacy and diagnostic accuracy of fine needle aspiration cytology (FNAC) in distinguishing non-neoplastic and neoplastic ovarian lesions and to determine reliable cytological criteria for typing neoplastic ovarian masses into benign and malignant tumours and their subtypes.
  
  
  METHODS
  FNAC was performed on 50 patients diagnosed as having an ovarian mass clinically and/or ultrasonographically. Detailed history, clinical examination and ultrasound findings in each case were recorded. The cytological diagnoses were categorized as neoplastic and non-neoplastic and further into benign and malignant neoplasms. These cytological diagnoses were then compared subsequently with the histopathological diagnoses.
  
  
  RESULTS
  The study material consisted of 57 aspirates from 50 patients. A comparison of cytological findings with the histological diagnosis was possible in 53 aspirates; in the remaining four cases (7%) the smears were acellular. On cytology, 31 lesions were diagnosed as neoplastic and 22 as non-neoplastic. The overall sensitivity of cytology in diagnosing neoplastic and non-neoplastic ovarian lesions was 93.9% and the specificity was 100%. The positive predictive value was 100% and negative predictive value 90.9%. The overall diagnostic accuracy was 96.2 %.
  
  
  CONCLUSIONS
  FNAC of ovarian masses is a minimally invasive procedure that can differentiate neoplastic from non-neoplastic ovarian lesions. It may help avoid unnecessary operations and preserve the reproductive ability in young patients. Furthermore, it also enables a satisfactory sub-categorization of ovarian tumours, which facilitates the choice of appropriate therapy.
