Growing teratoma syndrome is a rare phenomenon. Presented is a case of a 36 year old, G2P2 (2002) who consulted for abdominal enlargement and subsequently underwent exploratory laparotomy, peritoneal fluid cytology, left salpingooophorectomy, right oophorocystectomy, infracolic omentectomy and random peritoneal biopsy. Histopathology revealed immature teratoma of the ovary, FIGO grade III, stage IIIC. She received adjuvant chemotherapy using Bleomycin, Etoposide, Cisplatin. After the second cycle of chemotherapy, new lesions were appreciated in the right ovary and at the cul de sac for which she underwent exploratory laparotomy, peritoneal fluid cytology, total hysterectomy with right salpingooophorectomy, tumor debulking, infragastric omentectomy, random peritoneal biopsy. Histopathologic study showed mature teratoma. No further treatment was given. Presently, patient has no evidence of disease for 5 months.

The malignant transformation of a cystic teratoma is a rare event, occurring in about 0.2% to 1.8%. Primary malignant melanoma arising from the ovary is extremely rare. A primary melanoma in an ovarian cystic teratoma originates most frequently at the dermoepidermal junction, similar to a cutaneous melanoma. Though there are no standard adjuvant regimens for the treatment of primary malignant melanoma of the ovary. We present another case report of malignant melanoma developing in cystic teratoma.

OBJECTIVE: The aim of this study was to know the clinicopathological characteristics that help to make a decision about diagnosis and treatment of ovarian masses in Korean women. METHODS: Women who were undergone operations and histopathologically confirmed as ovarian masses at Inje University Busan Paik Hospital and Donrae Paik Hospital from January of 1997 to June of 2009 were enrolled in this study. Distribution according to histopathological types and ages were analyzed. RESULTS: Of the 2875 cases, there were 1078 cases (37.5%) of non neoplastic masses and 1797 cases (62.5%) of neoplastic masses. In the neoplatic masses, there were 1286 cases (44.7%) of benign tumors, 140 cases (4.9%) of borderline tumors and 371 cases (12.9%) of malignant tumors. Endometriomas were most common tumors (644 cases, 59.7%) among non-neoplastic masses. Mature cystic teratomas were the most common tumors (598 cases, 46.5%) among benign tumors. Mucinous cystadenomas were the most common types (105 cases, 75.0%) among borderline tumors. Epithelial ovarian cancers were the most common types (267 cases, 72.0%) among malignant tumors. As the result of age distribution, mature cystic teratomas were the most common types of the women of the first and second decade, endometriomas were the most common types of the women of the third and fourth decade, and benign epithelial tumors were the most common types of the women of fifth and after sixth decade. CONCLUSION: Taken as a whole, neoplastic ovarian masses were more common than non-neoplastic masses, but most common ovarian mass was endometrioma which is non-neoplastic mass.

OBJECTIVE: The purpose of this was to evaluate accuracy of frozen section diagnosis for ovarian tumors according to histologic type and malignant potential. METHODS: We compared the frozen section and final diagnosis of patients with ovarian tumors from April 2001 to April 2006. Of these 1138 cases, 628 cases (55.2%) were epithelial ovarian tumors. Benign, borderline, and malignant epithelial tumors were 380 (60.5%), 87 (13.9%), and 161 (25.6%) cases. The accuracy of frozen section diagnosis was analyzed according to histologic type and malignancy potential. RESULTS: The overall accuracy of frozen section diagnosis was 93.9%. The accuracy for benign, borderline, and malignant tumors were 93%, 92%, and 98%, respectively. The accuracy of frozen section diagnosis was significantly low in mucinous tumors and borderline malignant tumors. However the borderline malignancy was the only independent factor associated with the inaccuracy of frozen section diagnosis (OR: 12.2, 95% CI: 6.5-23.1). The sensitivity for immature teratoma was as low as 63.6%. CONCLUSION: Our data shows that the accuracy is low in mucinous tumors, borderline tumors, and immature teratomas and the borderline malignancy is independent factor associated with inaccuracy of frozen section diagnosis.

Strumal carcinoid of ovary is an unusual form of monodermal ovarian teratoma with thyroid-like follicles admixed with typical carcinoid tumor pattern. Most of them arise in dermoid cyst or in mature solid teratoma. Recently we experienced a case of strumal carcinoid postoperatively and report this case with a brief review of the concerned literatures.

We report a partial fetus-like structure (homunculus) in benign ovarian mature cystic teratoma removed from a 23-yr-old female. The cyst displayed various tissues derived from the three germ layers. The homunculus had a distinguished fetal cranial structure with one upper extremity. A partially developed osteocartilagenous skeleton was identified in the cranial structure of the homunculus. Intracranial structures such as cerebral cortex, retinal pigment, and leptomeninges were extruded from the partially disrupted calvarium.

Dermoid cysts are the most common type of ovarian neoplasms occurring during a woman's reproductive life and account for 25% of all premenopausal ovarian neoplasms. Intraoperative spillage of dermoid cyst materials may lead to febrile morbidity, ileus, peritonitis, adhesion or fistula formation. Rarely, malignant element spillage, if present, may also lead to cancer dissemination. The management of dermoid cyst is controversal. Recently, laparoscopic surgery for ovarian cysts has been increasingly accepted. But, in view of the high risk of intraperitoneal rupture of large sized cysts, many surgeon still prefer the laparotomic approach. Recently, we did laparoscopic salphingo-oophorectomy to the patient having 20cm sized dermoid cyst. Intraoperative spillage of cyst material occurred, but patient recovered without any postoperative complication. So, we present this case with brief review of the literatures.

OBJECTIVE: To know the clinical and histopathologic profiles of ovarian tumors. METHODS: 822 women undergone operations for their ovarian tumors were enrolled in this study from July of 1996 to June of 2004 at Inha University Hospital in S. Korea. Incidence, age, laterality and size were analyzed according to their histopathologic results. RESULTS: Among 822 women, there were 2.1% of non-neoplastic ovarian cysts, 81.0% of benign tumors, 4.4% of borderline tumors, and 12.5% of malignant tumors. Among benign tumors, 48.2 were cystic teratomas, 22.5% were mucinous, and 19.4% were serous tumors. Among borderline tumors, 52.8% were mucinous and 42.2% were serous. Among malignant tumors, 25.2% were serous and metastatic, respectively, and 18.4% were mucinous. The average and median age of non-neoplastic cysts were 39.1 +/- 12.7, 41 years old, those of benign tumors were 38.2 +/- 18.4, those of borderline tumors were 33.4 +/- 16.7, 28, and those of malignant tumors were 47.8 +/- 15.4, 49. The bilaterality of benign tumors was 10.7%, that of borderline were 16.7%, and that of malignant were 24.2%. The average and median diameter of non-neoplastic cysts were 3.2 +/- 1.4 cm, 3 cm, those of benign tumors were 8.1 +/- 4.3 cm, 7 cm, those of borderline tumors were 13.5 +/- 7.8 cm, 12 cm, and those of malignant tumors were 10.2 +/- 6.1 cm, 9.3 cm. CONCLUSION: We analyzed clinical and histopathologic data of 822 ovarian tumors.

Gliomatosis peritonei is the deposition of benign glial implants, more commonly associated with an immature ovarian teratoma. This paper reports a case of a 24 year old gravida 1 para 1 (1001) who underwent unilateral salpingo-oophorectomy and complete surgical staging for a preoperative diagnosis of ovarian new growth, probably malignant. Intraoperatively, aside from the ovarian mass on the right, there was also note of an omental mass. Histopathology revealed a mature ovarian teratoma for the ovary and gliomatosis peritonei for the omental mass. Gliomatosis peritonei is a rare entity. There are currently no guidelines on how patients with this condition can be followed up. Transvaginal sonography and annual measurement of alpha-fetoprotein may play a role in the follow-up of patients in low resource settings.
