Conjunctival involvement in Churg-Strauss syndrome

PURPOSE: To describe an unusual case of Churg-Strauss syndrome (CSS) that presented with a conjunctival nodule and was successfully treated with oral corticosteroids. METHODS: Case report. RESULTS: A 30-year-old woman with a history of adult-onset asthma, seasonal allergies, and a lung mass presented with a nodular elevation of the conjunctiva. Excisional biopsy demonstrated necrotizing eosinophilic granulomas. Systemic evaluation revealed peripheral eosinophilia and elevated IgE, consistent with Churg-Strauss syndrome. The patient's symptoms and eosinophilia resolved after an increase in the dose of oral corticosteroids. CONCLUSIONS: This case describes a unique presentation of conjunctival involvement in CSS that differs from prior case reports by having a small, well-demarcated nodule and lacking signs of active inflammation.
