[Hemolymphangioma of the orbit in children].

Orbital hemolymphangiomas are extremely rare. Clinical and computed tomographic brain scan aspects mimic "inflammatory orbital pseudotumors". They frequently fluctuate in size with upper respiratory tract infections and may bleed, causing acute exophthalmos. Therapeutic approach remains difficult as complete surgical excision is always impossible and postoperative complications frequent with acute inflammatory relapses and/or hemorrhages. We describe 2 children with orbital lymphangiomas presenting as orbit tumors.
