Benign ovarian cysts--a retrospective evaluation over two years

Area of Science:

• Gynecologic Pathology
• Oncology
• Reproductive Medicine

Background:

• Benign ovarian cysts are common, but accurate differentiation is challenging.
• Clinical presentation and gross features are often insufficient for precise cyst typing.
• Histological examination is essential for definitive diagnosis.

Purpose of the Study:

• To evaluate the histological subtypes of "benign" ovarian cysts.
• To assess the accuracy of initial clinical and gross diagnoses compared to histology.
• To emphasize the importance of detailed histological analysis in managing ovarian cysts.

Main Methods:

• Histological analysis of 89 ovarian cysts over 2.5 years.
• Supplementation of routine histology with ample blocking and deeper sectioning.
• Comparison of initial diagnoses with final histological classifications.

Main Results:

• Out of 89 cysts, 44 were neoplastic, 22 dysfunctional, 19 simple, and 4 endometriotic.
• Initial diagnoses were altered in 11.2% of cases following detailed histological examination.
• Neoplastic and dysfunctional cysts, with distinct clinical implications, were frequently misclassified initially.

Conclusions:

• Clinical diagnosis of benign ovarian cysts requires robust histological support.
• Detailed histological evaluation, including deeper sectioning, is vital for accurate cyst typing.
• Distinguishing between neoplastic, dysfunctional, simple, and endometriotic cysts impacts patient management.
