TL;DR: Although fibrous dysplasia and ossifying fibroma are similar disease entities, especially in the demonstration of the osteogenic lineage in stromal fibroblast-like cells, they show distinct differences that can be revealed by immunohistochemical detection of osteocalcin expression.

TL;DR: Insight is provided into possible mechanisms underlying the pathogenesis of phosphaturic mesenchymal tumor and imply a central role of the FGF1-FGFR1 signaling pathway.

TL;DR: The investigation of senescence-associated immune cell subsets from the spleens and mesenteric lymph nodes revealed an increase in PD-1 + CD44 high CD4 T cells as well as CD95 + GL7 + germinal center B cells, indicating that the long-term circadian misalignment exacerbates immune senescences and consequent chronic inflammation.

TL;DR: It is shown that lipoblastoma is a group of lipomatous tumors with PLAG1 rearrangement and overexpression, in agreement with previous studies.

TL;DR: A 35-year-old woman with a retroperitoneal Müllerian cyst with the tubal type of epithelium is reported, which is an extremely rare case among the known cases and Immunohistochemical tests showed that the lining cells were strongly positive for cytokeratins.
