High-resolution histopathology and transmission electron microscopy of lipedema adipose tissue (normal-BMI, stages 1-2) showed CD68+ macrophage infiltration increased exclusively in affected areas (similar to obesity but in normal-weight patients), along with endothelial/pericyte hyperproliferation (Ki-67+), severe endothelial barrier degeneration, calcium crystal and collagen (fibrosis) accumulation, and adipocyte cytoplasmic projections into the capillary lumen, indicating vascular and adipocyte pathology independent of obesity.
