  "statement": "This review reports that lipedema adipose tissue exhibits hypertrophic adipocytes with CD68+ macrophage infiltration in perinecrotic crown-like structures and around vessels, mast cells and T lymphocytes in hypervascular areas, and elevated blood VEGF leading to vessel proliferation, capillary dilation, hypoxia and fibrosis, with mast cells contributing to increased interstitial fluid, adipocyte deterioration and elastic fiber fragmentation; pain is described as a hallmark symptom.",
  "statement_pt": "Esta revisão relata que o tecido adiposo do lipedema apresenta adipócitos hipertróficos com infiltração de macrófagos CD68+ em estruturas semelhantes a coroas perinecróticas e ao redor de vasos, mastócitos e linfócitos T em áreas hipervasculares, e VEGF sanguíneo elevado levando à proliferação de vasos, dilatação capilar, hipóxia e fibrose, com os mastócitos contribuindo para o aumento do fluido intersticial, deterioração de adipócitos e fragmentação de fibras elásticas; a dor é descrita como sintoma marcante.",
