Objective: We analyzed the expression and immunolocalization of vascular adhesion protein (VAP)-1 in conjunctival tumors and normal conjunctival tissue of humans. Methods: Nine conjunctival tumors, including pyogenic granuloma and extranodal marginal zone B-cell lymphoma (EMZL), and 2 normal conjunctivas were analyzed by immunohistochemistry for VAP-1 and CD31 expression. Results: Immunoreactivity for VAP-1 was detected in the lumen of microvessels in pyogenic granuloma and in EMZLs. In contrast, normal bulbar conjunctival tissues demonstrated weak cytoplasmic immunoreactivity for VAP-1 in the blood vessels. Conclusions: The immunolocalization of VAP-1 varied in the histopathology of the conjunctiva, involving the pathology of inflammatory conjunctival disorders.
