A Case Report on Bortezomib-Induced Bilateral Chalazion.

A chalazion is a swollen bump on the eyelid that occurs when the eyelid's oil gland clogs up. Bortezomib is an FDA-approved novel agent for the treatment of patients with multiple myeloma (MM). Recently, there have been a few case reports on the possible association between eyelid chalazion and bortezomib therapy. We describe the case of an 87-year-old female diagnosed with MM who developed bilateral eye chalazion after being initiated on bortezomib. She was evaluated by an ophthalmologist, started on eye lubricants and antibiotic eye drops, and the bortezomib was discontinued until the resolution of the lesions was achieved. Physicians should be aware of these ocular complications of bortezomib, as early intervention can prevent worsening eyelid complications.
