Pyomyoma is a rare complication, which withoug antibiotics or surgical intervention, may cause sepsis and mortality. The present study reported a case of large uterine pyomyoma in a perimenopausal female. A 53-year-old multigravida woman was referred to the Department of Obstetrics and Gynecology (Wakayama Medical University, Wakayama, Japan) due to progressive abdominal distension. The patient presented with anemia gravis, severe inflammatory reaction and cachexia. Computed tomography revealed a large unilocular mass, 50 cm in size, with an irregular surface and thickened wall, occupying the entire abdomen. Following antibiotic medication, the patient underwent a total abdominal hysterectomy and bilateral salpingo-oophorectomy. Intraoperative findings demonstrated a solid tumor arising from the back of the uterine body. A total of 12 liters of purulent, malodorous fluid was drained from the tumor. The resected mass was 50 cm in size and 13.5 kg in weight. Cultures of the pus revealed the presence of Streptococcus agalactiae. Pathological findings revealed suppurative leiomyoma with no malignancy. Large pyomyoma is difficult to distinguish from a gynecological malignant tumor types, particularly in perimenopausal women with non-specific clinical presentation. Although pyomyoma is a benign tumor, care must be taken to discriminate these from large abdominal tumors. [ABSTRACT FROM AUTHOR]

The objective of the present study was to investigate the usefulness of the maximum standardized uptake value (SUVmax) of the primary tumor on preoperative 18F‑fluoro‑2‑deoxy‑D‑glucose (FDG) positron emission tomography and computed tomography (PET/CT) as a prognostic indicator in patients with endometrial neoplasms. A total of 75 patients with endometrial cancer or uterine carcinosarcoma who underwent surgical treatment were included in the present study. All patients underwent preoperative PET/CT, and the correlation between the SUVmax of the primary tumor and clinical outcomes was analyzed. The SUVmax was significantly higher in patients with stage II/III disease, a histology of grade 3 endometrioid adenocarcinoma and carcinosarcoma, a positive lymph node (LN) status, positive lymph‑vascular space involvement (LVSI), and deep (≥1/2) myometrial invasion. Receiver operating characteristic curve analysis revealed that the optimal cut‑off values of SUVmax for predicting a positive LN, LVSI and deep myometrial invasion were 7.49, 6.45 and 6.45, respectively. The overall survival (OS) and progression‑free survival (PFS) of patients with a high SUVmax were significantly lower compared with those of patients with a low SUVmax using the cut‑off value of 7.30. However, no significant difference was observed in the OS or PFS between the high and low SUVmax groups when analyzed in carcinosarcoma patients alone. Finally, multivariate analyses demonstrated that the SUVmax of the primary tumor was an independent prognostic factor for impaired PFS in 55 endometrioid adenocarcinoma patients; however, not in all patients, including those with carcinosarcoma. The present findings demonstrated that the SUVmax of the primary tumor may be a useful biomarker for predicting clinical outcomes of patients with endometrial cancer, although its prognostic impact appears to be limited in patients with uterine carcinosarcoma.

The objective of the present study was to investigate the prognostic value of 18F‑fluoro‑2‑deoxy‑D‑glucose (FDG) uptake by primary tumors on positron emission tomography/ computed tomography (PET/CT) in surgically resectable cervical cancer. A total of 59 patients with stage IA2‑IIB cervical cancer who underwent preoperative FDG‑PET/CT, followed by radical hysterectomy and lymphadenectomy, were included in the study. The maximum standardized uptake value (SUVmax) of the primary tumor was measured, and the association between the SUVmax and clinicopathological factors or patient outcomes was analyzed. The SUVmax was significantly higher in patients with an advanced stage, lymph node metastasis, lymph‑vascular space involvement and large tumors. The overall survival (OS) and progression‑free survival (PFS) of patients with a high SUVmax were significantly lower compared with patients with a low SUVmax, using an optimal cut‑off value of 7.36 for OS and 5.59 for PFS obtained from receiver operating characteristic curve analysis. Similarly, OS and PFS in patients with a high SUVmaxwere significantly lower in 39 patients with stage IB using a cut‑off value of 7.90 and 6.69 for OS and PFS, respectively. Finally, multivariate analyses showed that the SUVmaxof the primary tumor was an independent prognostic factor for impaired PFS in all patients and those with stage IB alone. These findings demonstrated that a high SUVmax on preoperative PET/CT was correlated with unfavorable clinical outcomes in patients receiving radical hysterectomy, suggesting that the SUVmaxof the primary tumor may be a prognostic indicator for surgically‑treated, early‑stage invasive cervical cancer.

Mature cystic teratomas are the most common among all ovarian neoplasms, representing 30-40% of the cases. However, to the best of our knowledge, there have been only two reports of mature cystic teratomas occurring in identical twins to date. We herein report a case of identical twins with mature cystic teratomas who were treated with laparoscopic surgery. A 32-year-old woman was referred to our hospital due to a tumor in the right ovary. The patient underwent laparoscopic resection of the ovarian tumor and the pathological diagnosis was benign mature cystic teratoma. Two years later, the identical twin of the abovementioned patient was referred to our hospital also due to a right ovarian tumor. The patient underwent laparoscopic resection of the ovarian tumor and the pathological diagnosis was benign mature cystic teratoma. Therefore, for early diagnosis, it may be important to consider the possibility of mature cystic teratoma in the identical twin of a patient, even in the absence of symptoms. [ABSTRACT FROM AUTHOR]
