We describe an extremely rare case of advanced pure primary ovarian squamous cell carcinoma (SCC), treated by adjuvant chemotherapy with dose-dense paclitaxel combined with carboplatin (dd-TC) plus the combination chemotherapy with irinotecan and cisplatin (CPT-P), with long-term recurrence-free survival. A 71-year-old woman complaining of lower abdominal pain was referred to our hospital and a 7-cm-diameter solid tumor was identified. She was diagnosed with a left ovarian tumor that was highly suspicious for malignancy based on ultrasonography, magnetic resonance imaging, and contrast-enhanced computed tomography. Bilateral salpingo-oophorectomy, low-anterior colon resection, and colostomy were performed. Intra- and post-operative histopathological diagnosis revealed International Federation of Gynecology and Obstetrics stage IIIc well-differentiated pure ovarian SCC. As adjuvant chemotherapy, 2 courses of dd-TC were administered, followed by 3 courses of CPT-P; the patient then underwent 4 additional courses of dd-TC. Both regimens were effective and there has been no recurrence or metastasis thus far in the 5 years since the operation.

OBJECTIVE: The purpose of this study was to develop a risk prediction score for distinguishing benign ovarian mass from malignant tumors using CA-125, human epididymis protein 4 (HE4), ultrasound findings, and menopausal status. The risk prediction score was compared to the risk of malignancy index and risk of ovarian malignancy algorithm (ROMA). METHODS: This was a prospective, multicenter (n=6) study with patients from six Asian countries. Patients had a pelvic mass upon imaging and were scheduled to undergo surgery. Serum CA-125 and HE4 were measured on preoperative samples, and ultrasound findings were recorded. Regression analysis was performed and a risk prediction model was developed based on the significant factors. A bootstrap technique was applied to assess the validity of the HE4 model. RESULTS: A total of 414 women with a pelvic mass were enrolled in the study, of which 328 had documented ultrasound findings. The risk prediction model that contained HE4, menopausal status, and ultrasound findings exhibited the best performance compared to models with CA-125 alone, or a combination of CA-125 and HE4. This model classified 77.2% of women with ovarian cancer as medium or high risk, and 86% of women with benign disease as very-low, low, or medium-low risk. This model exhibited better sensitivity than ROMA, but ROMA exhibited better specificity. Both models performed better than CA-125 alone. CONCLUSION: Combining ultrasound with HE4 can improve the sensitivity for detecting ovarian cancer compared to other algorithms.

BACKGROUNDWith the advent of color Doppler flow imaging (CDFI) and technological development of detection of serum tumor markers, new opportunities are presented to the improved risk of malignancy index (RMI) based on Jacobs' research for predicting ovarian malignancy in patients with adnexal masses.

METHODSOne hundred and eighty women with an adnexal mass admitted for primary laparotomy were studied. Tumor specific growth factor (TSGF) adjusted ultrasound scores and the results of Doppler blood flow analysis were obtained before the operation. Based on the parameters which had been studied in Jacobs' research, TSGF levels and the findings of color Doppler flow imaging, the risk of malignancy model was redesigned using a binary Logistic regression model. The diagnostic efficacy of the improved risk of malignancy index (improved RMI) was compared with the Jacobs' model RMI by receiver operator characteristic (ROC) curve.

RESULTSThe ROC curve showed a higher sensitivity (Mcnamer's test, P < 0.05) in the discrimination between benign and malignant adnexal masses for the improved RMI than the RMI. Compared with the RMI, the improved RMI had an advantage in prediction of ovarian germ cell tumors and granular cell tumor (28.57% vs.71.43%, P < 0.05) and the early stage tumors and borderline tumors (33.33% vs. 66.67%, P < 0.05).

CONCLUSIONThe predictability of the improved RMI is better than the classic Jacobs' model, especially in diagnosis of the ovarian germ cell tumors and granular cell tumor and other early stage adnexal tumors.

A mesothelial cyst of the round ligament is a rare cause of an inguinal mass. Clinically, it is frequently misdiagnosed as one of commoner diseases such as an inguinal hernia, femoral hernia, lipoma, and lymphadenopathy upon physical examination. Some previous reports elaborated the sonographic features of a mesothelial cyst of the round ligament. However, to our knowledge, few reports have described the CT features of a mesothelial cyst. We illustrated here the sonographic and multidetector CT features of a case of a mesothelial cyst of the round ligament that presented as an inguinal palpable mass and mimicked a metastasis in a patient with a Sertoli-Leydig cell tumor of the ovary.

We present a case of a 40-yr-old woman diagnosed with a primary malignant struma ovarii. The patient was admitted with the complaint of pelvic pain and a large pelvic mass in the mid-portion of lower abdomen on gynecological examination. Pre-operative tumor markers and routine biochemistry were unremarkable. She was treated with total abdominal hysterectomy and right salpingo-oopherectomy. Post-operatively, she was diagnosed with a malignant struma ovarii through the usage of histopathological criteria similar to the guidelines for primary thyroid gland disease. The patient was subsequently performed left salpingo-oopherectomy and retroperitoneal pelvic lympadenectomy for re-staging. Although, left ovary and lymph nodes were histopathologically normal, she was offered thyroidectomy but she refused to accept the offer. Thyroglobulin level was monitored in the post-operative period. She is free of the disease for 18 months.

OBJECTIVETo assess the value of color Doppler ultrasonography, contrast-enhanced ultrasound and detection of serum CA-125 levels in the differential diagnosis of ovarian masses.

METHODSThe findings of color Doppler ultrasonography, contrast-enhanced ultrasound and the serum levels of CA-125 were comparatively analyzed in 65 patients with ovarian masses, and the diagnostic accuracy of the 3 methods was estimated.

RESULTSOf the 65 cases of ovarian masses, 21 of the 35 patients with benign ovarian masses had serum CA-125 levels below 35 U/ml , and 28 of the 30 patients with malignant masses showed CA-125 levels over 35 U/ml. Color Doppler ultrasonography identified 30 benign and 22 malignant cases, but failed to produce definite results in 13 cases (including 5 with benign and 8 with malignant masses). By contrast-enhanced ultrasound, benign masses were found in 34 cases and malignant masses in 29 cases, and misdiagnosis occurred in 2 cases (including 1 case of thecoma and 1 of ovarian borderline tumor). With serum CA-125 detection, color Doppler ultrasonography and contrast-enhanced ultrasound, the diagnostic sensitivity for ovarian masses was 66.7%, 73.3%, and 96.7%, and the specificity was 60.0%, 85.7%, and 97.1%, respectively.

CONCLUSIONSDetection of serum CA-125 level and ultrasound examinations help in the diagnosis and differential diagnosis of benign and malignant ovarian masses. Compared with serum CA-125 detection and color Doppler ultrasonography, contrast-enhanced ultrasound is more informative on perfusion patterns of the ovarian masses to result in higher accuracy in early and differential diagnosis of the ovarian masses.

The association of intramuscular myxoma and fibrous dysplasia is a rare disease known as Mazabraud's syndrome. We present a case of Mazabraud's syndrome coexisting with a uterine tumor and resembling an ovarian sex cord tumor (UTROSCT). This uterine tumor showed a high mitotic index and cytological atypia. To the best of our knowledge, the coexistence of the two different entities has not been reported in the literature.

We report here on a 26-year-old pregnant female who developed hirsutism and virilization during her third trimester along with a significantly elevated serum testosterone level. Abdominal US and MR imaging studies were performed, and they showed unique imaging features that may suggest the diagnosis of pregnancy luteoma in the clinical context. After the delivery, the serum testosterone level continued to decrease, and it returned to normal three weeks postpartum. The follow-up imaging findings were closely correlated with the clinical presentation.
