Collision Tumors in Ovary: Case Series and Literature Review

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.

Surgery In Elderly

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.

Ovarian Tumours

Mature cystic teratomas account for 30–45 % of all ovarian tumours. Malignant transformation of these tumours is rare with squamous cell carcinoma (SCC) being the commonest histological type. During a 24-year period (1986–2010) we identified six women treated for SCC arising in a mature cystic teratoma at our institution. Each case was reviewed retrospectively recording presenting symptoms, tumour markers, preoperative imaging, tumour stage, management and outcome. Durable responses are difficult to achieve but best treatment response was seen in a woman who had partial response to chemo-radiotherapy. Concurrent chemo-radiation may be considered for disease confined to the pelvis.
