Extranodal Rosai-Dorfman Disease presenting as an isolated epibulbar mass

Abstract

Rosai-Dorfman disease is a rare idiopathic disorder characterized by painless lymphadenopathy with cervical involvement in more than 80% cases. We report a case of Rosai-Dorfman disease presenting as an isolated epibulbar mass in a healthy young adult male. Epibulbar involvement in Rosai-Dorfman disease is a rare presentation as can be seen from a review of all literature. The presentation, differential diagnosis and treatment are discussed.
