Orbital sarcoidosis presenting as diffuse swelling of the lower eyelid.

The author reports a case of orbital Sarcoidosis in a 70-year-old female that initially presented as diffuse swelling of the lower eyelid. The patient complained of painless swelling of the left lower lid without palpable mass, and a computerized tomography (CT) scan of the orbit was unremarkable. A serum angiotensin converting enzyme level was elevated, and hilar lymphadenopathy was noted on the chest CT. The patient underwent surgical debulking for histologic confirmation, which led to a final diagnosis of sarcoidosis involving the orbital fat. Unexplained chronic eyelid swelling without a mass should be considered a possible ophthalmic manifestation of orbital sarcoidosis.
