Abstract Beckwith–Wiedemann syndrome is the most common genetic overgrowth syndrome. Patients with Beckwith–Wiedemann syndrome may have hemihypertrophy, but their lymphatic vasculature is intact. We present a child with Beckwith–Wiedemann syndrome and lower extremity enlargement thought to be due to hemihypertrophy that was instead diagnosed with primary lymphedema. There are many causes of leg overgrowth in the pediatric population and misdiagnosis is common. While extremity enlargement secondary to hemihypertrophy may occur in 15% of patients with Beckwith–Wiedemann syndrome, progression and pitting edema only occur in primary lymphedema. This report highlights the importance of ensuring an accurate diagnosis so that patients are managed appropriately.
