Solid facial edema preceding a diagnosis of retro-orbital B-cell lymphoma

Persistent solid facial edema is a rare condition of unknown cause. Although acute facial edema has been associated with numerous disease processes such as infections, neoplasms, immune disorders, inflammation, neuropathic processes, drugs, mechanical obstructions, and trauma, solid facial edema has most often been associated with acne vulgaris. We report the first case, to our knowledge, of solid facial edema preceding a diagnosis of a subcutaneous scalp and orbital/periorbital B-cell lymphoma.
