In a comparative lymphoscintigraphy study (15 women with lipedema vs 15 with primary lymphedema), inguinal lymph nodes were absent in 14/15 lymphedema cases but only 1/15 lipedema cases (p<0.001) and colloid half-life was longer in lymphedema (230±92 vs 121±36 min, p<0.01), and the Stemmer sign is positive in lymphedema but negative in lipedema, with the review describing lymphedema and lipedema as distinct entities and lipedema's fat distinct from obesity (weight loss reduces truncal but not limb fat).

Lymphoedema and lipoedema of the extremities — Kröger (2008) ✓ verified — consistent · review · 2008 · reading confidence: high
“ausência de visualização de linfonodos inguinais em 14/15 casos de linfedema e apenas 1/15 de lipedema (p<0,001); meia-vida do colóide maior no membro patológico de linfedema (230±92 vs. 121±36 min, p<0,01)”
Comparative review explicitly distinguishing lipedema from lymphedema via clinical sign (Stemmer) and lymphoscintigraphy data, and from obesity via fat distribution response to weight loss; directly addresses the question's affirmative dire
