Candy Cane Hypopyon Secondary to Intraocular Mantle Cell Lymphoma: A Case Report

Bilateral hemorrhagic hypopyon, also known as candy cane hypopyon, is an extremely rare presentation which we report as a unique case in association with intraocular mantle cell lymphoma (MCL). A 63-year-old white male presented with a 3-week history of conjunctival injection OS that was unresponsive to erythromycin ointment and topical steroids, in the setting of recently discovered diffuse lymphadenopathy and malaise. On presentation, he was found to have bilateral hemorrhagic hypopyon. Lymph node biopsy was diagnostic of MCL, and subsequent anterior chamber paracentesis confirmed intraocular MCL. The patient was put into remission with intravitreal rituximab injections, systemic chemotherapy, and external beam radiation. Cases of MCL with ocular involvement typically involve ocular adnexal structures, and seldom involve the uvea. Furthermore, this patient represents an extremely unusual case in his presentation with a hemorrhagic hypopyon.
