Nabothian cysts are mucinous retention cysts formed through the accumulation of cervical mucus inside blocked cervical crypts leading to non-neoplastic mucinous cystic lesion in relation to the uterine cervix. The formation of Nabothian cysts is a common gynecological benign condition in women of reproductive age. While the presence of small-sized Nabothian cysts is usually clinically asymptomatic and requires no treatment or intervention, the diagnosis of larger Nabothian cysts can be mistaken with malignant tumors, including mucin producing carcinomas such as Adenoma malignum...

Abdominal wall endometriosis (AWE) is a rare form of endometriosis that usually develops in the scar after cesarean section (CS). Recently, the occurrence of AWE has been increasing together with the increase of CS incidence. AWE can be clinically misdiagnosed as hernia, lipoma, or hematoma. Here we retrospectively analyzed the clinical aspects of AWE and surgical approach in 14 patients from a tertiary hospital, who were treated by surgery, between 2012 and 2017. The mean age was 32.71 ± 8.61 years (range: 19-45)...

Malignant mesothelioma of the tunica vaginalis testis is an extremely rare tumor without specific clinical manifestations, mainly including hydrocele formation and a painless mass. We herein present the case of a patient with hydrocele of the left testis, without any other complaints. Tunica vaginalis subinvolution was performed, and postoperative pathological examination revealed a malignant mesothelioma arising from the left tunica vaginalis testis. Whole-body positron emission tomography-computed tomography (PET-CT) and subsequent abdominal and pelvic magnetic resonance imaging (MRI) revealed no evidence of local lymphadenopathy...

PURPOSE OF REVIEW: Superparamagnetic iron oxide nanoparticles (SPIONs) are tested to identify sentinel lymph nodes (SLNs) to exploit the advantages of targeted pelvic SLN dissection (sPLND), while circumventing the disadvantages of established radioactive labeling. Here we review recent studies about sPLND in prostate cancer (PCa), including the first results of SLN detection using intraprostatic SPION-injection. RECENT FINDINGS: A recent systematic literature review reveals that the diagnostic accuracy of sPLND is comparable with extended PLND (ePLND)...
