  “distribuição desproporcional de TAS e ausência de relação causal com obesidade”
  Brazilian Delphi consensus (expert agreement, not primary evidence)

  narrative review
• Non-contrast MR Lymphography of lipedema of the lower extremities — Cellina et al. (2020) ✓ verified — consistent · cohort · 2020 · reading confidence: high
  The article provides evidence of distinct imaging findings in lipedema patients, supporting the notion that it is a separate disease from obesity and lymphedema.
• Impact of hormones on lipedema development: a systematic literature review — Lüchinger et al. (2026) ✓ verified — consistent · review · 2026 · reading confidence: high
  “Os achados apoiam a reclassificação do lipedema como distúrbio hormonalmente influenciado, distinto da obesidade”
  The systematic review evaluates the pathophysiological mechanisms of lipedema and supports its distinction from obesity.
• Lipedema: an overview of its clinical manifestations, diagnosis and treatment of the disproportional fatty deposition syndrome – systematic review — Forner‐Cordero et al. (2012) ✓ verified — consistent · review · 2012 · reading confidence: high
  “TC sem contraste: sensibilidade 95% e especificidade 100% para diagnóstico de lipedema (Monnin-Delhom). Critério diagnóstico diferencial chave: pele do dorso do pé poupada no lipedema (sinal do cuffing), Stemmer negativo; ao contrário do linfedema.”
  This is a systematic review of available literature on lipedema that explicitly lists differential diagnoses (lymphedema, obesity, lipohypertrophy, phlebedema), supporting lipedema as a distinct clinical entity, but the evidence base is des
• Lipedema — Okhovat & Alavi (2015) ✓ verified — consistent · review · 2015 · reading confidence: high
  “Lipedema não responde a dieta restrita nas pernas — principal distinção clínica com obesidade simples”
  This is a narrative literature review that explicitly states lipedema is distinct from lymphedema and obesity, supporting the question's affirmative direction, but provides no primary data and is limited by the low quality of evidence inher
• Lipedema: Clinical Features, Diagnosis, and Management — Mortada et al. (2025) ✓ verified — consistent · review · 2025 · reading confidence: high
  “the current research indicates that lipedema appears to be a clinical entity related to genetic factors and fat distribution, although distinct from lymphedema and obesity”
  Narrative review directly addressing the question, explicitly stating lipedema is distinct from obesity and lymphedema; supports the affirmative, but evidence level is low (non-systematic review noting scarcity of high-quality trials).
• Modern approaches to the diagnosis and multimodal management of lipedema: A phlebology-oriented clinical framework. — Hendesi F. (2026) ✓ verified — consistent · review · 2026 · reading confidence: high
  “Accurate diagnosis of lipedema relies primarily on clinical evaluation, including pain assessment, tissue palpation, characteristic fat distribution, and exclusion of lymphedema and simple obesity.”
  A narrative review that frames lipedema as a distinct systemic disorder requiring exclusion of obesity and lymphedema, but presents no original comparative evidence testing the distinction; on-topic background rather than a direct test.
