Abstract: PURPOSE: To describe a case of diffuse conjunctival papilloma in an immunocompromised individual on tacrolimus that was refractory to treatment with interferon α-2b, but responded to topical mitomycin-c. OBSERVATIONS: A 79-year-old Caucasian female with a history of a liver transplant twenty years ago, who was immunosuppressed with tacrolimus (2 mg daily) presented with a diffuse conjunctival and corneal squamous papilloma. Following treatment with four weekly subconjunctival interferon-α2b injections (3 million units/0.5 mL) and 3 months of topical interferon-α2b therapy (1 million units/mL), four times daily, slow progression was documented. The patient was switched to topical mitomycin-c drops (0.04%) administered four times daily (one week on and one week off) with dramatic regression of the tumor. CONCLUSIONS AND IMPORTANCE: In cases of conjunctival squamous papilloma that do not respond readily to topical interferon, topical mitomycin-c is an alternate therapeutic option. We hypothesize that use of tacrolimus may have contributed to the lack of response to topical interferon-α2b.
