All treatments for CSDs other than the levonorgestrel intrauterine system shortened menstrual periods. Laparoscopic surgery was effective for patients with fertility requirements.

Leiomyomatosis peritonealis disseminata (LPD) is a rare smooth muscle tumor, which is characterized by the dissemination of multiple smooth muscle-like nodules throughout the omental and peritoneal surfaces. The present report describes the case of a 33-year-old woman who had previously undergone laparoscopic myomectomy due to a bizarre leiomyoma. Five years after the initial operation, the patient was referred to our hospital with irregular episodes of right abdominal pain. As the presentation was highly suspicious of malignant uterine tumor metastasis or LPD, the patient subsequently underwent laparoscopic total hysterectomy, bilateral salpingo-oopherectomy, omental resection and excision of some of the disseminated nodules. Histological examination confirmed the diagnosis of LPD. Under laparoscopic examination, LPD must be distinguished from metastatic leiomyosarcoma and other malignant conditions. Frozen section biopsy examination may help with the diagnosis, but the final diagnosis relies on pathological examination. The etiology of LPD includes several theories, such as the hormonal, genetic and iatrogenic theories. A gonadotropin-releasing hormone agonist may be successful in shrinking the nodules. In women who have completed their families, total abdominal hysterectomy, salpingo-oophorectomy, omentectomy and debulking appears to be the optimal treatment.

Our results suggest that ultrasound elastography could be helpful for discrimination of low- and high-grade serous ovarian carcinoma. Low-grade lesions are stiffer and not as elastic as high-grade lesions.

The aim of the present study was to evaluate tumor stiffness by ultrasound elastography, which has the potential to provide additional information that is useful in predicting the response to neoadjuvant chemotherapy (NACT) in high-grade serous ovarian carcinoma (HGSC) patients. In total, 32 patients with International Federation of Gynecology and Obstetrics stage III and IV epithelial ovarian cancer treated with NACT underwent transvaginal and transabdominal sonography, followed by elastography and finally, by interval cytoreductive surgery. Histopathological analysis revealed 24 (75%) HGSCs. The mean elasticity score was statistically higher for the post-NACT lesions than for the pre-NACT lesions (3.13±0.57 vs. 2.04±0.51, respectively; P<0.001). The median elasticity score for the pre-NACT lesions on the four-point scale was 2, and the score for the post-NACT lesions was 4. Cases of post-NACT with scores of 3 and 4 had a higher optimal cytoreduction rate than cases with scores of 1 and 2 (93.8 vs. 25.0%, respectively; P<0.001). When the post-NACT elasticity scores of 3 and 4 were used for the prediction of optimal cytoreduction, elastography exhibited 88.2% sensitivity, 85.7% specificity, a 93.8% positive predictive value, a 75.0% negative predictive value and 87.5% accuracy. The results of the current study suggested that elastography is a sensitive tool for the evaluation of NACT in patients with HGSC and that it may aid gynecologists in choosing the optimal cytoreduction.
