Background: This article describes the differential diagnosis of conjunctival papillomas and reviews the treatment options with a focus on the new topical interferon alpha 2 beta therapy.
Case: A 45-year-old white man presented with a red right eye of approximately 6 months' duration. The lesion was suspicious and suggestive of malignancy; therefore, the patient was referred for consultation. The lesion was diagnosed as a conjunctival papilloma. The patient was placed on topical interferon alpha 2 beta eye drops, and within 2 weeks he experienced complete lesion regression.
Conclusion: Interferons, in particular interferon alpha-2b (IFN-alpha2beta), have recently been shown to be successful in treating conjunctival papillomas and conjunctival intraepithelial neoplasia (CIN). Previously, treatment was limited to observation for asymptomatic patients. Larger lesions in symptomatic patients were treated by surgical excision and cryotherapy. Additional treatment modalities included topical antimetabolite treatment with mitomycin-C and 5-fluorouracil. These treatments, although effective, had significant attendant postsurgical complications and toxic ocular adverse reactions. Interferons represent a new successful treatment modality.

Introduction And Importance: Conjunctival squamous cell carcinoma (SCC) is the most advanced form of ocular surface squamous neoplasia (OSSN), with varying incidence rates influenced by factors such as age, UV exposure, and occupation. Early detection is crucial, but misdiagnosis is common, especially when SCC mimics benign conditions like pterygium.
Case Presentation: An 83-year-old Caucasian male farmer presented with a rapidly enlarging nasal limbal lesion, initially misdiagnosed as pterygium.

Histone deacetylase HDAC6 has been implicated in regulating antiviral innate immunity. However, its precise function in response to DNA virus infection remains elusive. Herein, we find that HDAC6 deficiency promotes the activation of cGAS-STING signaling and type I interferon (IFN) production, both in vitro and in vivo, resulting in a decrease in HSV-1 infection.
