title: Histological pattern of ovarian neoplasma.
abstract: OBJECTIVE
  To see the morphological pattern of benign and malignant ovarian neoplasms.
  
  
  METHODS
  Retrospective study of all consecutive cases of ovarian neoplasms diagnosed at Aga Khan University Hospital between 1st January 1993 and 30th September 1998.
  
  
  METHODS
  The Section of Histopathology, AKUH, Karachi.
  
  
  METHODS
  Of 855 ovarian tumours 506 (59.18%) were benign and 349 (40.81%) malignant. Surface epithelial-stromal tumours comprised 63.50% of all tumours. Benign cystic teratoma was the commonest benign tumour (35.17% of all benign tumours) and serous cystadenocarcinoma was the commonest malignant tumour (33.33% of all malignant tumours). Mucinous cystadenocarcinomas are more common in our population as compared to the West and borderline and malignant mucinous tumours occur at a younger age group. Malignant germ cell tumours are also common in our population.
  
  
  CONCLUSIONS
  Except for the greater frequency of malignant mucinous and germ cell tumours, the findings of our series correspond to the published Western data.
