Human papillomavirus (HPV)-associated trilateral squamous neoplasia in immunocompetent individual.

Purpose: To describe a case of bilateral conjunctival and cervical human papillomavirus (HPV)-related squamous neoplasia.

Case Description: A healthy immunocompetent 55-year-old lady came to our attention for prosecution of care of a right recurrent conjunctival squamous cell carcinoma. Upon examination, she was found disease-free in the right eye but displayed a left conjunctival intraepithelial neoplasia (CIN grade I) and low-grade cervical squamous dysplasia. HPV infection with genotypes 16 (right eye), 11 and 39 (left eye) and 39 (uterine cervix) was also detected.

Conclusion: Simultaneous uterine and conjunctival HPV-related squamous neoplasia can occur in immunocompetent individuals. Auto-inoculation and repeated exposure to HPV could explain coexistence of different genotypes.
