Purpose: To evaluate the prevalence of undiagnosed and asymptomatic HIV infection in patients with ocular surface squamous neoplasia (OSSN) in an urban patient population in Malawi.
Methods: A consecutive series of patients presenting with OSSN was evaluated in an African academic centre. A detailed history and physical examination in 53 consecutive patients with conjunctival squamous cell carcinoma and conjunctival intraepithelial neoplasia were performed. Thirty eight (72%) patients agreed to undergo serological HIV testing.
Results: Seventy-nine per cent (30 of 38) patients were HIV positive. None of the patients had previous HIV testing or was aware of having symptoms of HIV. Seventy per cent (n = 21) of the HIV-positive patients had no other symptoms suggestive of HIV infection or any other disease. Patients were far more likely to refuse HIV testing if they were married and male.
Conclusions: The conjunctival tumour may be the primary and only apparent manifestation of HIV in patients presenting with OSSN in Sub-Saharan Africa.
