Histomorphological Spectrum of Ovarian Tumours in a Tertiary Care Centre of North India: A Case Series.

Ovarian tumours constitute the second most common tumour of the female genital tract after cervical cancers. The study describes the histological subtypes of ovarian neoplasms along with other parameters like age, laterality and consistency of lesion in a tertiary care centre in Uttarakhand. The retrospective data of ovarian tumours sent to the Department of Pathology was collected over a period of 4.5 years. They were classified into benign, borderline and malignant categories in the respective histological subtypes (surface epithelial, germ cell, sex cord stromal and metastatic) based on the latest WHO classification. The consistency of tumour, laterality and age of the patient were also evaluated. Of the 130 cases studied, 73 (56%) were benign, 13 (10%) were borderline and 44 (34%) were malignant. The majority of cases (73.1%) were surface epithelial tumours, followed by germ cell tumours (20.8%), sex cord stromal tumours (4.6%) cases and metastatic tumours (1.6%). Most cases (80.8%) showed unilateral involvement while 19.2% cases had bilateral involvement. The majority of cases in the present study were benign. Serous cystadenoma was the most common benign tumour with its malignant counterpart being the most common tumour in the malignant category.
