Anterior Uveitis and Iris Nodules That Are Associated With Langerhans Cell Histiocytosis

To describe a case of Langerhans cell histiocytosis (LCH) that involved the anterior uveal tract. Interventional case report. A retrospective review was conducted on a patient with iris nodules and anterior uveitis in the setting of LCH. Visual acuity and clinical findings that were noted on slit lamp biomicroscopy were extracted. An 18-year-old male patient with unilateral anterior segment inflammation and iris nodules experienced visual improvement from 20/200 to 20/25 after treatment with a 5-day course of topical corticosteroids. Regression of the iris nodules and anterior segment inflammation was also noted. Bone marrow aspirate confirmed recurrent, active LCH. The clinician should include LCH in the differential diagnosis when faced with anterior segment inflammation in conjunction with iris nodules. Additionally, LCH can be treated successfully with topical corticosteroid therapy.
