Low-grade fibromyxoid sarcoma (LGFMS) is a distinctive slow growing soft tissue neoplasm, mostly affecting young individuals with no gender difference. It usually arises in deep soft tissue of the lower limbs and trunk, but few cases of LGFMS located in pelvis have been reported. We describe the magnetic resonance imaging(MRI) features of LGFMS located in the anterior pelvic wall of a 21-year-old female and correlate them with clinicopathological features. The tumor was completely resected and there is no recidivism during the follow-up one year. We report on the radiological findings of LGFMS with histological correlation. Awareness of the imaging features may be useful for the diagnosis of LGFMS and helpful to distinguish among mimics.

Hollyhock (Alcea rosea (Linn). Cavan) is an herbaceous flowering plant with significant applications in urban greening, soil remediation, and traditional medicine. However, its genetic diversity and molecular characteristics at the population level have not been explored yet. Here, the phenotypic and genetic diversity of 162 hollyhock accessions from China revealed extensive variation among 11 traits and strong correlations between several quantitative traits. Whole-genome re-sequencing of 32 randomly chosen accessions identified 10,468,760 core single-nucleotide polymorphisms (SNPs) distributed evenly across the genome, except for on chromosome 21, and the average nucleotide diversity (π) was calculated to be 0.00397. Principal component analysis showed that these 32 accessions could be divided into four subpopulations, which was in agreement with the population structure analysis, and the subpopulations were strongly correlated with geographic location. A neighbor-joining dendrogram displayed similar clusters, except for accessions HuB25 and HLJ28, which formed two separate clusters. Our findings illuminate the genetic diversity in hollyhock and provide valuable information for hollyhock breeding.

INTRODUCTION: Intrapancreatic fat deposition is related to insulin resistance and type 2 diabetes mellitus. However, the association between intrapancreatic fat deposition and coronary artery disease has not been well studied. In this study, we investigated the associations between intrapancreatic fat deposition alone or in combination with triglyceride-glucose (TYG) index and the risk of coronary artery calcification (CAC) in a general population. METHODS: A total of 9,479 participants who underwent CT scans for lung cancer screening from 2018 to 2020 were included in this study. The TYG index was calculated through the following equation: Ln (fasting glucose [mg/dL] × fasting TG [mg/dL]/2). Pancreatic CT attenuation was used as a marker of intrapancreatic fat deposition. CAC was evaluated on noncardiogram-gated chest CT. RESULTS: CAC was detected in 2,447 of 9,479 participants. The prevalence of CAC was significantly lower in subjects with high pancreatic CT attenuation (37.8% in the first quartile [Q1] vs 17.8% in the fourth quartile [Q4], P < 0.001). Pancreatic CT attenuation was associated with the occurrence of CAC (odds ratio 0.82, 95% confidence interval 0.69–0.97, Q4 vs Q1). The area under the curve of the combination of pancreatic CT attenuation and the TYG index was significantly greater than that of TYG and pancreatic CT attenuation alone in identifying CACs (0.646 vs 0.596 and 0.612, P < 0.001). DISCUSSION: Intrapancreatic fat deposition was associated with CAC, and the combination of pancreatic CT attenuation and the TYG index performed better than TYG or pancreatic CT attenuation alone in identifying CACs.
