Magnetic resonance imaging features of uterine adenosarcoma: case series and systematic review.

Objectives: To comprehensively summarize the characteristics of magnetic resonance imaging (MRI) findings of uterine adenosarcoma through a systematic review and case series analysis.

Methods: A literature search was conducted in MEDLINE, Scopus, and Embase databases on June 3, 2024. In total, 25 cases from 23 articles were selected, and five cases from the authors' institution were included.

Recurrent severe anemia associated with a jejunal arteriovenous malformation in pregnancy: A case report.

Background: Small intestinal arteriovenous (AV) malformations may cause gastrointestinal hemorrhage, occasionally leading to anemia; however, they are rarely seen in pregnancy. This report presents a case of a pregnant woman who had recurrent severe anemia that was attributed to a small hemorrhagic intestinal arteriovenous malformation.

Case Presentation: A 24-year-old pregnant woman (gravida 2, para 1) presented with a low hemoglobin concentration (3.

S100-stained perineural invasion is associated with worse prognosis in stage I/II colorectal cancer: Its possible association with immunosuppression in the tumor.

Perineural invasion (PNI) is known as a poor prognostic factor in colorectal cancer (CRC). Although histopathological evaluation of PNI is usually conducted on hematoxylin and eosin (HE)-stained sections (HE-PNI), it remains controversial whether PNI can be precisely evaluated only by HE-staining, and its concise mechanisms causing worse prognosis remains elusive. In this study, we examined the impact of PNI evaluated by S-100-immunostaining (S100-PNI) on postoperative mortality in 279 consecutive CRC patients and further investigated its association with the tumor immune microenvironment.
