Inflammatory pseudotumor of the eyelid.

We present three patients whom we believe developed idiopathic inflammatory pseudotumors confined to the eyelid tissues with no evidence of orbital involvement. All three patients were misdiagnosed initially as having lesions of an infectious etiology. All three patients responded completely and rapidly to oral steroid therapy after the correct diagnosis was confirmed by biopsy. We believe that pseudotumor of the eyelid is a distinct subtype of idiopathic inflammatory pseudotumor.
