Abstract:An immunocompetent, 25-year-old gentleman with bilateral chronic uveitis presented to various uveitis clinics at different points of time with documented typical clinical features of Toxoplasma Chorioretinitis (Headlight in fog appearance), Behcet's Disease (Hypopyon with peripheral retinal vasculitis), and Presumed Ocular Tuberculosis (Granulomatous Intermediate Uveitis with positive Interferon-gamma release assay) and had been treated with anti-toxoplasma drugs, oral prednisolone, and immunomodulation with o… Show more
“…In one case, a diagnosis of choroidal melanoma was made, but immunohistochemical studies revealed LCH [10], and in the second eye, the iris portion of an iridociliochoroidal mass was found to be LCH after fine-needle aspiration [7]. Some reported vitreous biopsy for diagnosis of intraocular LCH [15], whereas others made the diagnosis based on a systemic history of LCH [11,16,17], as we did for our patient.…”
Background. This study is aimed at exploring a case of choroidal Langerhans cell histiocytosis (LCH) successfully treated with systemic corticosteroid and immunosuppressant. Case presentation. A 24-year-old man with known multisystem LCH developed loss of vision, ocular pain, conjunctival injection, panuveitis, and a ciliochoroidal mass. After receiving an intravenous methylprednisolone pulse, oral high-dose corticosteroids, and methotrexate, the mass resolved quickly and completely without flare-ups during 6 months of follow-up. Conclusions. Intraocular involvement of LCH is rare and can present with or without a history of multisystemic disease. The diagnosis is challenging, and the standard treatment is not established. Systemic anti-inflammatory and immunosuppressive therapy could be an effective treatment, as the LCH itself contains an essential element of inflammation and the symptoms may be mainly inflammatory.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
