Histologically distinct tumors that coexist in an organ without any histological admixture at their interface are denominated collision tumors. We report 3 cases of colliding mature cystic teratoma with mucinous cystadenoma and a case of mature cystic teratoma colliding with benign Brenner tumor in the ovary. We also provide a literature review based on 35 previously published ovarian collision cases. Ovarian tumors from all classes, benign, borderline and malignant lesions may collide. Both our case series and the literature review indicate that ovarian tumor collisions tend to be clinically and ultrasonographically/radiologically unrecognized. The awareness among surgeons, radiologists and pathologists of this rare phenomenon and histological recognition are crucial in order to offer adequate treatment to patients. There is a need to identify novel and more specific imaging clues pointing towards collision tumors in the ovary.

Objectives. The study was conducted to characterize the use of the laparoscopic surgery in elderly patients. Methods. The medical records of elderly patients aged ≥65 years who underwent laparoscopic surgery were retrospectively reviewed for diseases, surgical procedures, histological diagnosis, intraoperative and postoperative complications, and reasons for presentation. Results. Of the 405 patients who underwent laparoscopic surgery between January 2005 and March 2012, 41 (10.1%) were aged ≥65 years. The most common disease treated by surgery was ovarian tumor, followed by uterine prolapse. Histological diagnosis of ovarian tumor specimens obtained from 23 patients included serous cystadenoma (44.0%), mature cystic teratoma (20.0%), mucinous cystadenoma (20.0%), and endometrioma (4%). In contrast, in the non-elderly group, the most common histological diagnosis was endometrioma (42.9%), followed in order by mature cystic teratoma (28.3%), serous cystadenoma (18.0%), and mucinous cystadenoma (4.7%). While 23.7% of the non-elderly patients required emergency laparoscopic surgery, none of the elderly patients required emergency surgery. Only 1 of 27 patients who underwent surgery for an ovarian or adnexal mass presented with abdominal pain. No one developed serious intraoperative or postoperative complications. Conclusion. Laparoscopic surgery can be safely performed in elderly patients. It should be noted, however, that few elderly patients with benign pelvic mass manifest symptoms before undergoing surgery.

A collision tumor is the coexistence of two adjacent, but histologically distinct tumors without histological admixture in the same tissue or organ. Such tumors have often been reported in various organs, but location in the ovary is rare. The juxtaposition with dermoid cysts has been reported as comprising approximately 5% of benign mucinous ovarian tumors and rare examples of proliferating mucinous tumors. Authors are reporting a case of collision tumor which included benign mucinous cystadenoma and benign cystic teratoma. The gynecologists and pathologists should be aware of such combination of tumors. The case was diagnosed post-operatively. It is important to correctly diagnose the component of tumor for further management and favourable prognosis. Frozen section intra-operatively plays an important role in diagnosing such tumors.
