Fertility Preservation in Ovarian Collision Tumour: A Case Report

Dermoid cysts are the most common germ cell tumours encountered in the reproductive age group. The coexistence of dermoid cysts with other histological types within the ovary is rare. An uncommon combination of mature cystic teratoma with mucinous cystadenoma is being presented here. The challenges in managing these tumours arise from their large size, making cystectomy while preserving the normal ovary a daunting task. Preoperative identification of separate components and thorough discussion with the histopathologist play a crucial role in effective management. The presence of malignant components and the diagnosis of the most aggressive component guide the direction of the management protocol. Our case highlights the positive outcome of fertility-sparing surgery in the context of bilateral ovarian masses.
