A Case of Gastric Atypical Lipomatous Tumor/Well‐Differentiated Liposarcoma With Endoscopic Morphological Changes

open access: yesDEN Open, Volume 6, Issue 1, April 2026.
ABSTRACT Atypical lipomatous tumor/well‐differentiated liposarcoma is a locally aggressive mesenchymal neoplasm composed of adipocytes and stromal cells. Gastric cases are exceedingly rare, and their malignant potential remains unclear. We report a case of a woman in her 60s who was found to have multiple submucosal tumor‐like lesions of the stomach ...

Meflin/ISLR is a meningeal cell‐specific marker involved in the development of meninges and meningioma progression

open access: yesBrain Pathology, Volume 36, Issue 2, March 2026.
Mesenchymal stromal cell‐and fibroblast‐expressing Linx paralogue (Meflin) is expressed in embryonic meninges and contributes to meningeal homeostasis. In meningiomas, elevated Meflin correlates with higher grade and recurrence. Single‐cell RNA sequencing revealed a Meflin‐high tumor cell subset marked by reduced proliferation, WNT6 expression, and ...
