Area of Science:

  • Vascular Medicine
  • Dermatopathology

Background:

  • Chronic primary lymphedema of the lower extremity can predispose individuals to secondary complications.
  • Understanding the pathogenesis of skin changes in advanced lymphedema is essential for effective management.

Observation:

  • A 26-year-old male presented with severe lymphedema (elephantiasis) of the left leg.
  • Clinical examination revealed confluent, violaceous, macerated plaques and ulcers on the dorsal aspect of the left foot's toes.

Findings:

  • Histopathology confirmed a proliferation of small blood vessels.
  • Evidence of extravasated erythrocytes and hemosiderin deposits supported the diagnosis of acroangiodermatitis.

Implications:

  • Acroangiodermatitis is a significant complication of chronic lymphedema, characterized by vascular changes in the skin.
