Background: Endometrial cancer is one of the most common malignancies among women worldwide. Although this cancer is often diagnosed at early stages, the need for biomarkers of diagnosis remains a necessity to overcome conventional invasive procedures of diagnosis. Objective: In our study, we aim to investigate the diagnostic value of microRNA-21 in endometrial cancer and its relation to clinicopathological features. Methods: We used RT-qPCR to measure the expression of microRNA-21 in 71 tumor tissues, 53 adjacent tissues, and 54 benign lesions. Results: Our results show that microRNA-21 is a potential biomarker for endometrial cancer with an area under the receiver operating characteristic curve of 0.925 (95% CI = 0.863 - 0.964, P<0.0001). The sensitivity was 84.51% (95% CI = 74.0 - 92.0) and specificity was 86.79% (95% CI = 74.7 - 94.5). For discrimination between benign lesions and controls the AUC was 0,881 with a sensitivity of 100% (95% CI = 93.4 - 100.0) and specificity of 66.04 % (95% CI = 51.7 - 78.5), and for discriminating benign lesions from tumors the AUC was 0,750 with a sensitivity of 54.93% (95% CI = 42.7 - 66.8) and specificity of 90.74% (95% CI = 79.7 - 96.9). We also found that tumors with elevated microRNA-21 expression are of advanced FIGO stage, high histological grades, and have cervical invasion, myometrial invasion and distant metastasis. Conclusion: Our findings support the important role of miR-21 as a biomarker for the diagnosis of endometrial cancer. Further studies on minimally invasive/noninvasive samples such as serum, blood, and urine are necessary to provide a better alternative to current diagnosis methods.

Introduction: Verrucous carcinoma of the vulva is a rare lesion, mainly affecting postmenopausal women, this lesion is a distinct and particular entity in the classification of vulvar carcinomas and its progression is uncertain and unpredictable. It is characterized by its extensive exophytic growth without infiltration of the basement membrane. Case Report: We report a case of verrucous carcinoma of the vulva collected at the Mohamed VI cancer treatment center in Casablanca, we will discuss through a literature review, its therapeutic and evolutionary diagnostic modalities. Conclusion: Therefore, verrucous carcinoma is a rare entity and its evolution is mainly local, rarely metastatic. It is the indication for exclusive surgical treatment with wide excision without lymphadenectomy in principle. Radiation therapy provides no survival benefit. The prognosis is relatively good but burdened by local recurrences.
