Background: To evaluate the predictive role of a risk of malignancy index in discriminating between benign and malignant adnexal masses preoperatively. Materials and Methods: A total of 408 patients with adnexal masses managed surgically between January 2010 and February 2014 were included. The risk of malignancy indices (RMI) 1, 2, 3 and 4 were calculated using findings for ultrasonography, menopausal status, and CA125 levels. Histopathologic results were the end point. ROC analysis was used for the sensitivity and the specificity of the models. Results: Some 37.6 % of the cases were malignant in the postmenopausal group while 7.9 % were malignant in the premenopausal group. Pelvic pain was the most common complaint, and the majority of the cases were diagnosed at stage 3. The RMI 1, 2, 3 and 4 yielded percentage sensitivities of 76.1, 79.1, 76.1 and 76.1 and specificities of 91.5, 89.1, 90.6, 88.6, respectively. RMI 1 was the most reliable test in the general population according to AUC levels and Kappa statistics. From ROC analysis results of post/premenopausal women, the RMI 1 (cut off: 200) yielded sensitivities of 84.0/60.9 and specificities of 87.7/92.5. With RMI 2 they were 88.6/60.9 and 80.0/91.0, with RMI 3 84.0/60.9 and 87.7/91.8, and with RMI 4 (cut off:400) 81.8/47.8 and 83.6 /44.0. Although test performance of RMI methods were good in a general population and postmenopausal women, the RMI inter-agreement validity was only moderate or fair in premenopausal women. Conclusions: Our study confirms the effectiveness of RMI algorithms in postmenopausal women. However, more sensitive tests are needed for premenopausal women.

We report the case of a girl with peritoneal tuberculosis (Tb) who presented with mimicking features of ovarian cancer including massive ascites, elevation of CA-125 and ovarian masses. These ovarian masses cannot be ruled out malingnacy with image study. Gram stain, acid-fast stain, bacteriological and mycological culture of centrifuged ascites cells were negative. Tumor markers revealed an elevated CA-125 level of 112 U/mL and adenosine deaminase level were significantly high with 118 U/L. Diagnostic laparoscopy was done. The histology of the peritoneum and the ovary showed multiple granulomatous nodules with epithelioid cells and multi-nucleated giant cells. And there were no evidence of malignancy. Furthermore acid-fast bacilli (AFB) was identified in this specimen. Peritoneal Tb was difficult to diagnosis in our patient because it mimicked ovarian cancer. And this is the first case of abdominal Tb mimicking ovarian cancer in children in Korea.

Ovarian cysts are the most common cystic abdominal masses in female newborns. It is believed to be derived from an overstimulation of the ovarian follicles by maternal, placental, and fetal hormones. Although most ovarian cysts resolve spontaneously, surgical management is mandatory for life-threatening, complicated cases, including torsion, intracystic hemorrhage, and rupture of the cyst. Rupture of ovarian cysts is thought to be exceedingly rare, but can lead to severe hemorrhagic ascites or peritonitis. We managed a case of a ruptured ovarian cyst in a female newborn who presented with mild abdominal distension and two episodes of gross hematuria. Exploratory laparotomy revealed a right ovarian cyst with torsion and rupture. She was successfully treated with a right salpingo- oophorectomy with no sequelae.

Background: Ovarian cancer is the most common cancer cause of gynecologic cancer deaths. In order to increase the likelihood of patient survival through primary operation by gyneco-oncologists, an appropriate algorithm for referral is considered here. Materials and Methods: Suspicious adnexal mass cases including ovarian malignancy probability score-1 (OMPS1) scores between 2.3-3.65 are re-evaluated by OMPS2. Sensitivity and specificity of each score were determined. Results: Sensitivity and specificity with a 3.82 score of OMPS2 in the studied subgroup (OMPS1 scores between 2.3-3.65) were 64% and 76.9% respectively. Conclusions: Management of OMPS1 scores of below 2.3 with sensitivity of 100% and above 3.65 with specificity of 72.9% is clear. In the subgroup of cases with OMPS1 score between 2.3-3.65, OMPS2 is helpful for triage with a cutoff score of 3.82.

Two female Yorkshire terrier was referred to Veterinary Medical Teaching Hospital, Seoul National University. In case 1, clinical signs were vomiting, anorexia and weight loss. Cystic intraabdominal mass was identified in radiographic and ultrasonographic examination. In case 2, clinical sign was abdominal distension. In radiographic and ultrasonographic examination, cellular ascites and bilateral intraabdominal masses next to kidneys were observed. Many clusters of glandular epithelial cells with anisocytosis, anisokaryosis, high N:C ratio coarse chromatin and prominent nucleoli were shown in cytologic examination of sanguineous ascites. In all two cases exploratory laparotomy was performed and enlarged ovaries were observed (Rt: 6$\times$5$\times$5 cm and Lt: 3$\times$2$\times$1 cm in case 1 and 3$\times$2$\times$1 cm bilaterally in case 2). After ovariohysterectomy histopathologic examinations were performed. Histopathologically the masses were diagnosed as ovarian adenocarcinoma and ovarian cystadenocarcinoma in case 1 and case 2, respectively. In both dogs no further chemotherapy was carried out. These two dogs had no gross evidence of tumor recurrence at the time of 3 months after tumor resection, but long-term follow-up might be needed.

Objective: The aim of our study is to compare an ovarian malignancy prediction model based on age and four sonographic findings (OMPS1) with a new model called OMPS2 which differs just by adding serum CA125 measurement to (OMPS1). Methods: In a cross sectional comparative study OMPS1 was validated in 830 operated ovarian masses within a 3 years period (2006-2009). Logistic regression analysis was used to construct OMPS2 based on OMPS1 adding serum CA125 findings. The area under the curve for two models was compared in 411 patients. Results: OMPS2 was calculated as follows: OMPS1 + 1.444 (if serum CA125= 36-200) or 3.842 (if serum CA125 is more than 200). AUC of OMPS2 was increased to 84.3% (CI 95% 78.1- 89.8) in comparison to OMPS1 with AUC of 78.1% (CI 95% 71.8-84.5). Conclusion: Our second model is more accurate in prediction of ovarian malignancy, compared with our first model.

Purpose : Inguinal hernias are common in children and sometimes are associated with dangerous complications, such as incarceration. There are no established management guidelines for ovarian hernias. We have reviewed the clinical course of ovarian hernias in infants. Methods : We reviewed the medical records of female infants diagnosed with ovarian hernias by ultrasonogram at Kwandong University College of Medicine, Cheil General Hospital, and the Women's Healthcare Center between March 2001 and August 2007. We analyzed the patients gestational age, birth weight, age at the time of detection of the inguinal mass, the patients chief complaints, operative time, post-operative complications, and ultrasonographic findings. Results : Eight female infants had ovarian hernias, four of whom were born prematurely. Seven infants had left-sided ovarian hernias, and one infant had a right-sided ovarian hernia. Five infants underwent surgery and there were no postoperative complications or recurrences. Three girls did not have surgery, and the ovarian hernias regressed spontaneously, with no recurrences or complications. The regression time of inguinal masses ranged from 70-161 days after birth. Conclusion : Physical examination to detect movable masses within the labium major in premature female infants is important because the incidence of premature inguinal hernias is much higher than in term infants. No rational medical treatment plans for female ovarian hernias have been published to date. We cared for three girls with spontaneous regression of ovarian hernias. Pediatricians should be aware whether emergent surgery for ovarian hernias is indicated.

Anaplastic lymphoma kinase (ALK) rearrangement, is a kind of driver mutation, accounts for 3%-5% of non-small cell lung cancer (NSCLC). NSCLC patients harboring ALK fusion genes have distinct clinical features and good response to ALK inhibitors. Metastasis from lung cancer to the ovary has rarely been known. We report a case of a 54-year-old woman with bilateral ovarian metastases from ALK rearranged NSCLC. She underwent bilateral salpingo-oophorectomy for ovary masses, which were progressed after cytotoxic chemotherapy although primary lung mass was decreased. Histopathological examination of the ovary tumor showed characteristic adenocarcinoma patterns of the lung and ALK rearrangement.

Echinococcosis is a multisystem disease and has propensity to involve any organ, an unusual anatomical site, and can mimic any disease process. Primary peritoneal echinococcosis is known to occur secondary to hepatic involvement but occasional cases of primary peritoneal hydatid disease including pelvic involvement have also been reported. We report here 1 such case of primary pelvic hydatidosis mimicking a malignant multicystic ovarian tumor where there was no evidence of involvement of the liver or spleen. Our patient, a 27-year-old female, was detected to have a large right cystic adnexal mass on per vaginal examination which was confirmed by ultrasonography. Her biochemical parameters were normal and CA-125 levels, though mildly raised, were below the cut off point. She underwent surgery and on exploratory laparotomy, another cystic mass was found attached to the mesentery of the small gut. The resected cysts were processed histopathologically. On cut sections both large cysts revealed numerous daughter cysts. Microscopic examination of fluid from the cysts revealed free scolices with hooklets and the cyst wall had a typical laminated membrane with inner germinal layer containing degenerated protoplasmic mass. The diagnosis of pelvic hydatid disease was confirmed and patient was managed accordingly. Hydatid disease must be considered while making the differential diagnosis of pelvic cystic masses, especially in endemic areas.

A 1-year-old, 2.35 kg spayed female American short hair cat was referred with episodic signs of heat at 3 months after ovariohysterectomy. Through the screening tests, bilateral cystic, ovary like masses were shown at the caudal to both kidneys with high serum estradiol concentration. It was considered that the patient was suffered from ovarian remnant syndrome. Laparoscopic exploration was performed, and each of mass lesions was resected by ultrasonic scalpel. Patient was recovered favorably and has been doing well without recurrence of estrus signs until 2 years after surgery.
