Ovaries are very complex organs in terms of embryology and histology. It undergoes cyclical changes from adolescence to menopause and gives rise to different types of cells, which has capacity to produce different type of lesions and tumours¹.

A number of non-neoplastic lesions can occur from neonatal period to postmenopausal age group. Most are functional in nature and resolve with minimal treatment. Some of the non-neoplastic lesions like massive edema of ovary, stromal hyperplasia, large follicular cyst, pregnancy luteomas and granulomatous inflammation can be confused with neoplasm clinically, intraoperatively and on morphological examination. The main aim lies in distinguishing ovarian neoplasmsfrom the wide spectrum of non-neoplastic lesions. Despite the new techniques like imaging studies, the diagnosis is mainly dependent upon histopathological examination.

The present study is being undertaken to review in detail the different varieties of ovarian lesions in and around Tirunelveli and assess their characteristics with regards to incidence, age and histopathological appearances.

Aim and Objectives

1. To determine the nature of non-neoplastic lesions presented to the department of Pathology, Tirunelveli Medical College.
2. To ascertain the frequency and distribution of ovarian lesions among various age group and to correlate them with the clinical features.
3. To study the histomorphological diversity of various non neoplastic lesions of ovary.
