The purpose of this study was to evaluate the incidence, clinical features, microbiology, risk factors, and treatment outcomes in cases of ocular surface squamous neoplasia (OSSN) with coexisting microbial keratitis (MK). ⋯ Rarely, MK can coexist with OSSN leading to a poor treatment outcome. Male sex, human immunodeficiency virus seropositivity, large limbal pigmented OSSN lesion with keratin and corneal component, noduloulcerative morphology, and scleral invasion were risk factors for this association.
