Lipedema adipose tissue shows distinct histopathologic features (adipocyte hypertrophy, increased intercellular fibrosis, macrophage infiltration), aberrant lipid metabolism, and a unique adipogenesis gene expression profile compared to BMI-matched controls, differentiating it from obesity and lymphedema.

Evidence over time

Evidence (2)

• Adipose Tissue Hypertrophy, An Aberrant Biochemical Profile and Distinct Gene Expression in Lipedema — Felmerer et al. (2020) ✓ verified — consistent · cross sectional · 2020 · reading confidence: high
  The study directly compares lipedema patients to BMI-matched controls using histopathology, serum analysis, and gene expression arrays, finding distinct molecular and morphological hallmarks; however, the sample size is small (10 lipedema,
• A Comparative Analysis to Dissect the Histological and Molecular Differences among Lipedema, Lipohypertrophy and Secondary Lymphedema — von Atzigen et al. (2023) ✓ verified — consistent · cross sectional · 2023 · reading confidence: high
  “VEGF-R3 aumentado exclusivamente em linfedema (3,227±1,067 fold) vs todas as condições (lipedema 1,006, lipohipertrofia 1,406) — marcador molecular específico de linfedema”
  The study directly compares lipedema, lipohypertrophy, and secondary lymphedema using histological and molecular methods in matched samples, identifying distinct characteristics that support lipedema as a separate condition from both obesit
