Strumal Carcinoid

Ovarian primary carcinoid tumors are very rare, accounting for 0.5-1.7% of all carcinoid tumors and 3% of ovarian teratomas. This type of tumor frequently arises from a mature cystic teratoma. The primary ovarian carcinoid tumors are divided into 4 major types, based on their histological characteristics: insular, trabecular or mucinous pattern. Strumal carcinoid refers to insular or trabecular pattern associated with struma ovarii. The strumal type is the most common histologic form, accounting for 40% of primary ovarian carcinoid tumors. Approximately 5% of carcinoid tumors of the non-mucinous type can be malignant. However, in the case of ovarian strumal carcinoid, the occurrence of metastasis is unusual. This article is based on a case of a 30-year-old nulliparous woman diagnosed with strumal carcinoid, who presented a right ovarian tumor suggestive of teratoma synchronous to a breast cancer. She was referred to our center for fertility preservation.

Strumal Carcinoid

Primary ovarian carcinoid tumors are extremely rare. Ovarian strumal carcinoid is usually derived from mature cystic teratoma, an ovarian germ cell tumor composed of two distinctive components characteristic thyroid tissue intermixed with a carcinoid tumor. The incidence of stromal carcinoid tumor is accounting for 0.3-1% of all ovarian tumors and 3% of all mature teratomas. Herein, we report a 25-year-old female presented with severe abdominal pain. She had right struma ovarii after Laparoscopic-Assisted Ovarian Cystectomy (LAOC) procedure one year ago. The sonography of abdomen images study demonstrated a well capsulated cystic mass measured up to 11 cm in dimension. The mature cystic teratoma was the first diagnostic possibility. She underwent the laparoscopy-assisted left ovarian cystectomy. Histopathological and immunohistochemical examinations confirmed strumal Carcinoid Tumor of the Ovary (SCTO) arising from strum ovarii in the left ovary. She was recovered well and was still asymptomatic after two years follow-up. In conclusion, we first describe the primary SCTO arising from a heterochronous struma ovarii. The symptoms of SCTO are usually non-specific and misleading. Therefore, it is important to fully understand the characteristics, diagnosis and management of SCTO. Diagnosis should be confirmed by pathology and immunohistochemistry, and clinically metastatic carcinoid should be excluded.

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.

While mature cystic teratoma of the ovary is the most common ovarian tumor in young women, immature teratoma is a very rare tumor, representing only 1% of all ovarian cancers. In the three cases presented here, young women who were suspected to have mature cystic teratoma, based on CT scan and MRI, were ultimately diagnosed with immature teratoma Ic (b) G1 after laparoscopic operation. They underwent salpingo-oophorectomy of the affected side only and have shown no sign of recurrence during follow-up. We sometimes encounter patients with immature teratoma who have no findings pointing to malignancy on CT or MRI. Generally, if the components of immature nerve cells that represent immature teratoma are very few, it is difficult to diagnose the entity as immature teratoma with imaging evaluations such as CT or MRI. In many hospitals, laparoscopic surgery is selected for patients with ovarian mature teratoma. Therefore, it is essential to attempt as much as possible not to disseminate the fluid content of the tumor into the intra-abdominal space during laparoscopic operation, because in rare cases the tumor turns out not to be benign mature teratoma.
