Lack of response to systemic corticosteroids in patients with lymphangioma.

Lymphangioma is a benign nonencapsulated orbital tumor that is difficult to treat. Recently, systemic corticosteroids were advocated as a safe and effective alternative to surgical drainage of the cysts. We describe our experience with 3 cases in which proptosis progressed or did not improve despite the exclusive use of systemic steroids for 1 week, necessitating urgent surgical intervention. These three cases demonstrate that at least in some cases, steroids alone may be ineffective, and alternative interventions must be undertaken.
