Spectrum of Ovarian Cystic Lesions-A Histopathological Study

Objective: The aim of this retrospective study is to determine the frequency of ovarian cystic lesions involving both neoplastic and non-neoplastic entities, its distribution and histopathological spectrum including both benign and malignant lesions. Method: This study involved analyzing 67 cases of cystic ovarian lesions/tumors reported in Histopathology section of Tezpur Medical College and hospital in a 24 month period. They were classified according to WHO classification of ovarian tumors (2003). Clinical details of patients were perused according to archived records. Result: Cystic lesions were grouped according to their nature whether neoplastic or non-neoplastic and whether benign, borderline or malignant. The neoplastic cystic lesions comprise the majority of lesions comprising 64.17% while non-neoplastic lesions comprise 35.82%. Among neoplastic lesions cyst adenomas comprise majority (46.5%) of benign lesions and malignant lesions comprise 6.9% of lesions. Among non-neoplastic lesions simple/follicular cysts comprise 54.16% of lesions. Conclusion: Benign cystic neoplastic lesions out number the non-neoplastic lesions and benign tumors are more common than malignant ones. Ovarian lesions are not easily detected by physical or laboratory investigations hence one has to depend in addition to microscopic appearance of the tumor other clinical parameters such as age of the patient, presenting complains, location of lump and dimension of lump.
