“…The logistics and potential adverse acute and late effects from the recommended radiotherapy were discussed, including but not limited to conjunctivitis, cataract formation (up to 50% of the patients), mild xerophthalmia (20-40% of the patients), corneal ulceration (very low risk at this dose), vision loss (extremely low risk as this dose), dermatitis, infection, pain, fatigue, and radiation-induced malignancies. 11,12 The purpose of this case is to demonstrate the rare finding and potential association of peripheral ulcerative keratitis to the underlying disease of MALT lymphoma. We hope that this case is illustrative and informative for ophthalmologists and other physicians, as early detection and treatment of MALT lymphoma is favorable for patient outcomes.…”
