Sarcoidosis presenting as multilobular limbal corneal nodules

To review reported external ocular manifestations of sarcoidosis and to present bilateral, multilobular, nodular, limbal, corneal nodules as being a unique manifestation of the disease.

A 16-year-old Saudi girl presented with bilateral, multilobular, solid, limbal nodules, with a vascular supply from the conjunctival vessel, and associated membraneous conjunctivitis and healed trachoma. The Schirmer's test revealed less than 2 mm in both eyes with tear meniscus less than 2 mm. Biopsy of an associated palpebral conjunctival nodule was performed, in addition to a gallium scan, chest X-ray, and a serum angiotensin-converting enzyme (SACE) level.

The culture showed beta-hemolytic streptococci. Gallium scan showed intake by both lacrimal glands. Her chest X-ray results were normal, as was the SACE level. Biopsy of the excised conjunctival nodule disclosed a noncaseating granulomatous reaction with epithelioid and giant cells, and chronic inflammatory cell infiltrate confirming a diagnosis of sarcoidosis.

A multilobular, nodular, perilimbal mass as a unique manifestation of sarcoidosis is presented. A streptococcal membraneous conjunctivitis and healed trachoma superimposed. A review of sarcoidosis of the external eye is included.
