In lipedema subcutaneous adipose tissue, interstitial fibrosis precedes adipocyte hypertrophy (present at stage I), crown-like structures appear at all stages, IL-6 and TNF are upregulated at stages II–III in affected thighs, macrophage polarization shifts from M2-dominant (anti-inflammatory) at stage I toward M1-like (pro-inflammatory) at stage III, and VEGFC is upregulated in advanced disease—collectively delineating a stage-dependent inflammatory and fibrotic progression in affected tissue.
