Background: This report discusses the current literature on both non-invasive and invasive SMILE ((i)SMILE) lesions of the cervix with focus on the pathology and its related clinical diversity in several cases. Currently, the knowledge on (i)SMILE is limited to single case reports and series. As a consequence, consensus guidelines regarding the management are lacking. Although there is overlap with both high grade squamous intra-epithelial lesion (HSIL) and adenocarcinoma in situ (AIS) on immunohistochemical analyses, it is recommended to treat SMILE like AIS and further excision is needed when surgical margins are positive for SMILE on conization. (i)SMILE, should be considered as a rare subtype of adenocarcinoma of the cervix, and should be treated as such.
Case Report: We describe a case with a SMILE lesion undergoing a subsequent robotic hysterectomy after conization and two cases with iSMILE: one case with an early FIGO-stage 1B1 iSMILE tumor, undergoing a robotic radical hysterectomy with sentinel procedure, and one case undergoing a robotic-assisted pelvic/para-aortic lymph node staging dissection, confirming a metastatic FIGO-stage 3C2 (for primary chemo-radiotherapy treatment).
Conclusion: Here, we report for the first time a few cases of (i)SMILE with different clinical presentations, their management and follow-up. Immunohistochemical characteristics are given for both primary lesions as well as the metastases.

Cervical cancer is one of the deadliest cancers that pose a significant threat to women's health. Early detection and treatment are commonly used methods to prevent cervical cancer. The use of pathological image analysis techniques for the automatic interpretation of cervical cells in pathological slides is a prominent area of research in the field of digital medicine.

Objective: To explore the risk factors associated with the pathological progression to invasive carcinoma following the conization of cervical high-grade squamous intraepithelial lesions (HSIL) and to construct a risk prediction model to guide preoperative risk assessment and optimize the selection of surgical approaches.
Methods: A retrospective analysis was conducted on the clinical data of 3337 patients who underwent cervical conization for HSIL at Hunan Provincial Maternal and Child Health Care Hospital from December 2016 to March 2022. The patients were categorized into the pathological progression group (398 cases) and the nonprogression group (2939 cases) based on postconization pathology results.

Background: Cervical cancer is a common cancer worldwide, with > 85% of deaths occurring in Lower- and Middle-Income Countries where resources for screening programs are limited. Women living with HIV (WLHIV) are at increased risk. HPV test-and-treat is a screening strategy where women with HPV are offered ablative treatment of the cervix to reduce the risk of invasive cancer.

Objective: To evaluate the 36-month clinical performance of Single Bond Universal Adhesive (SBU; 3M ESPE, Germany) in non-carious cervical lesions (NCCLs) using different modes of adhesion according to the FDI criteria. The primary outcome was the retention loss of the restorations, while the secondary outcomes included marginal staining, marginal adaptation, post-operative sensitivity and tooth vitality, recurrence of caries erosion and abfraction, and tooth integrity, all evaluated according to the FDI criteria.
Materials And Methods: In this study, the SBU Adhesive was applied to 246 NCCLs of 25 patients using different modes of adhesion: Self-etch (SE), selective-enamel-etching (SLE), and etch-and-rinse (ER).

Background: This study aimed to investigate the potential utility of Epithelial-mesenchymal transition (EMT) signaling cell detection in the early diagnosis of cervical lesions.
Methods: Enrichment of cervical epithelial cells was carried out using a calibrated membrane with 8-μm diameter pores. RNA-in situ hybridization (RNA-ISH) was employed to detect and characterize EMT cells utilizing specific EMT markers.
