[Orbital lymphangioma. Apropos of 2 uncommon cases]

Lymphangiomas can be considered as hemodinamically isolated vascular hamartomas. They are rare tumors, and their orbito-palpebral location can be cosmetically and functionally detrimental. In severe cases, the treatment is mainly surgical and effective only if complete removal is performed. The result is often deceiving because of the diffuse extension of these tumors. We hereby report two exceptionally severe cases that both presented with major cosmetic impairment and visual loss. We discuss literature available, the management and the methods of treatment and the non-surgical alternatives.
