A 13-year-old adolescent was admitted to our clinic with a history of otalgia, odinophagia, and subconjunctival hemorrhage (red eye). After the patient had used ophthalmic tobramycin/dexamethasone and oral amoxicillin for 3 days, prescribed when she was seen in an emergency service, the conjunctival lesion had not improved. On admission, examination of the patient revealed unilateral temporal nodular episcleritis (Table) of her left eye (arrow), arthritis of her left ankle, symmetric erythema nodosum on her legs, and a fever (temperature, 38°C). Ocular sarcoidosis was diagnosed by conjunctival biopsy; the specimen showed a noncaseating granuloma. Culture was negative for bacteria, fungus, and parasites. The patient had no reaction to the tuberculin test, had no signs of intrathoracic disease, and the levels of the angiotensin-converting enzyme as well as serum and urinary calcium were normal. The lesion resolved after 2 months of treatment with ophthalmic dexamethasone.TABLECauses of EpiscleritisData from Br J Ophthalmol.1Watson PG Hayreh SS Scleritis and episcleritis.Br J Ophthalmol. 1976; 60: 163-191Crossref PubMed Scopus (386) Google Scholar Collagen vascular diseases (ie, rheumatoid arthritis, systemic lupus erythe-matosus, polyarteritis nodosa, and spondyloarthritis)GoutInfectious diseases (tuberculosis, Lyme disease, syphilis)Granulomatous diseases (Wegener granulomatosis, sarcoidosis) Open table in a new tab Sarcoidosis is less common in children than in adults. In a 15-year study in Denmark, the incidence of sarcoidosis was 0.06 case per 100,000 children 4 years of age oryounger; it increased gradually with age to 1.02 cases per 100,000 adolescents 14 to 15 years of age. In adolescents, the clinical picture was similar to that in adults.2Iannuzzi MC Rybicki BA Teirstein AS Sarcoidosis.N Engl J Med. 2007; 357: 2153-2165Crossref PubMed Scopus (1610) Google Scholar Uveitis or iritis is the most common manifestation, occurring in 24% to 56% of children, followed by conjunctival granulomas.2Iannuzzi MC Rybicki BA Teirstein AS Sarcoidosis.N Engl J Med. 2007; 357: 2153-2165Crossref PubMed Scopus (1610) Google Scholar, 3Shetty AK Gedalia A Childhood sarcoidosis: rare but fascinating disorder.Pediatr Rheumatol Online J. 2008; Sep 23; 6: 16Crossref PubMed Scopus (116) Google Scholar
