Purpose: To report a case of extremely rare anaplastic T-cell lymphoma of the urinary bladder in an advanced stage, with completely unspecific radiological features and symptomatology mimicking necrotic myomas. Case Report: A 38-year-old women was admitted for pelvic pain, dysuria, enlarged uterus, subfebrile temperature, but without vaginal bleeding and hematuria. On ultrasound scan necrosis of the uterine myomas was suspected. Magnetic resonance imaging revealed an anteuterine tumor (9×9×11 cm) infiltrating the uterus and urinary bladder and retrouterine formation (7×5×7 cm) adhering to the posterior uterine wall and rectum, right kidney hy-dronephrosis, and parailiac lymphadenopathy. Cystoscopy confirmed the presence of the tumor on the posterior bladder wall and bladder roof infiltrating the right ureteral orifice. Histopathological and immunohistochemical analyses of tumor biopsy confirmed the presence of T-cell anaplastic ALK+ non Hodgkin’s lymphoma of the urinary bladder. Conclusion: This case report shows that pelvic pain and dysuria alone can imply on urinary bladder tumors even in the absence of hematuria. Additionally, uniqueness of this case lies in the younger age of the female patient. Moreover, the authors showed for the first time that lymphomas could spread locally into both uterus and intestines, without systemic dissemination. © 2019 S.O.G. CANADA Inc.. All rights reserved.

Introduction: Good preoperative tumor triage is essential for choosing the appropriate approach. Objective: The study aim was to identify factors from standard preoperatively collected data, which could predict the nature of adnexal masses prior surgery. Material and Methods: The study involved all women treated in the Clinic for Gynecology and Obstetrics Clinical Center of Serbia for adnexal tumors throughout a period of 18 months. On admission, detailed anamnestical and laboratory data were obtained and ultrasound scans were performed. Obtained data were compared with hystopathological findings of tumors. Methods of correlation and logistic regression were applied to create association models. Results: Three new models for predicting tumor nature were achieved from anamnestical data, characteristics of women and tumors, and laboratory analyses. Two statistically significant (p = 0.000) equations were obtained for anamnestical data and characteristics of women and tumors, while three were made for laboratory analyses. Sensitivity of anamnestical malignancy index (AMI) was 73.33%, specificity 72.87%, positive predictive value (PPV) 39.49% and negative predictive value (NPV) 91.88%. Sensitivity of characteristic malignancy index (CMI) was 92.38%, specificity 67.36%, PPV 40.59% and NPV 97.34%. Sensitivity of laboratory malignancy index (LMI) was 56.45%, specificity 90.24%, PPV 68.63%, and NPV 84.57%. Conclusions: The best predictors of malignancy are menopausal status, body mass index (BMI), age, metastases, ascites, tumor marker CEA level, and erythrocyte sedimentation rate (ESR). Along with the risk of malignancy index (RMI), for more reliable triage and preoperative tumor evaluation the authors propose introduction of another three indexes (AMI, CMI, LMI) in clinical practice.

Granulosa cell tumors (GCTs) are characterized by slow growth, local spread, and late recurrence. The authors report the case unique for both unusually large dimensions of the recurring tumor and the fact that it was confined only to the omentum, where it has recurred 41 years after the initial surgery including salpingo-oophorectomy. This is the longest reported period from initial diagnosis to the recurrence of GCT. This case report is important as it proves that recurrence of GCT is possible even after an extremely long period of time after the initial surgery, due to the nature of this tumor, and the inhibition of apoptosis process. © 2018 S.O.G.
