Bilateral HPV Positive Squamous Cell Carcinoma In Situ of Conjunctiva.

A 45 year-old woman presented with blurred vision and irritation of the left eye. Clinical examination revealed a superior palpebral conjunctival lesion consistent with a diagnosis of papilloma. She was lost to follow up despite repeated attempts to schedule a biopsy, and presented again after an extended period with bilateral disease. Subsequent biopsy confirmed bilateral squamous cell carcinoma in situ which was human papilloma virus-16 positive by molecular testing. She declined further treatment; during the subsequent year, the lesions extended across the bulbar conjunctiva bilaterally.
