Clear cell carcinoma arising from abdominal wall endometriosis is an exceptionally rare malignancy that typically develops at prior surgical scar sites. We report a case of a woman in her 50s with a history of cesarean section who presented…

Per- and polyfluoroalkyl substances (PFAS) are reportedly associated with adverse obstetric outcomes, including premature labor and gestational diabetes. We aimed to evaluate associations of maternal PFAS exposure with obstetric and birth o…

Fallopian tube carcinoma, presenting as an inguinal hernia, is a rare entity. We report the case of a woman in her 70s with a history of hysterectomy and right oophorectomy 29 years prior who presented with left cervical lymphadenopathy and…

Growth and immune process dysregulation can result in both cancer and nonmalignant disease (hereditary or acquired, with and without predisposition to malignancy). Moreover, perhaps unexpectedly, many nonmalignant illnesses harbor genomic a…

Ossification of the posterior longitudinal ligament of the spine (OPLL) is an intractable disease leading to severe neurological deficits. Its etiology and pathogenesis are primarily unknown. The relationship between OPLL and comorbidities,…

We report a 33-year-old man who presented with recurrent right pneumothorax. Computed tomography (CT) showed the presence of a large bulla with a maximum diameter of 8 cm in the right middle lobe; he subsequently underwent bullectomy. Histo…

IntroductionAmong diseases that cause small bowel obstruction, internal hernia may result in severe outcomes. Therefore, emergency laparotomy has been often performed, but it may be invasive. We experienced a case of a broad ligament hernia…

Next-generation sequencing has enabled patient selection for targeted drugs, some of which have shown remarkable efficacy in cancers that have the cognate molecular signatures. Intriguingly, rapidly emerging data indicate that altered genes…

ObjectiveThe estrogen metabolite 2-methoxyestradiol has shown antitumorigenic action in some epithelial tumors. In the present work we investigate its effects in ovarian cancer used alone or in combination with other apoptotic-inducing reag…

Environmental contaminants affect a wide variety of biological events in many species. Dioxins are typical environmental contaminants that exert adverse oestrogen-related effects. Although their anti-oestrogenic actions are well described, …

CT findings in 37 cases with pathological diagnosis of uterine adenomyosis were reviewed retrospectively. The attenuation coefficient of adenomyosis is almost same as normal parenchyma on both plain and enhanced CT. The margin was obscure e…
