Conjunctival chronic lymphocytic leukemia presenting as bilateral chronic conjunctivitis.

Purpose: This report describes a case of conjunctival chronic lymphocytic leukemia (CLL) in a 73 year-old female with a prior history of CLL thought to be in remission who presented with bilateral chronic conjunctivitis. Observation: Examination revealed bilateral conjunctival injection, mildly purulent discharge, and the presence of large follicle-like lesions involving the bilateral superior and inferior palpebral conjunctiva. Conjunctival cultures grew Corynebacterium species. The patient was treated with topical antibiotics and steroids which improved the conjunctival injection and discharge, but the follicle-like lesions persisted. A conjunctival biopsy was performed and was consistent with the diagnosis of chronic lymphocytic leukemia. Fundoscopic exam did not demonstrate posterior uveal or retinal involvement. She was referred to her oncologist for further evaluation and management. Marked clinical improvement was noted after starting treatment with ibrutinib. Conclusions and importance: This case demonstrates a rare ocular manifestation of the most common form of leukemia. It happened to present with common, nonspecific symptoms of eye redness, discharge, and follicular reaction consistent with a bilateral chronic conjunctivitis. Clinical appearance and symptoms improved with topical steroids and eventually resolved with systemic bruton kinase inhibitor therapy.
