PURPOSE: To evaluate frequency of conjunctival tumors in all ages and compare benign vs malignant counterparts. DESIGN: Retrospective series. METHODS: setting: Tertiary referral center. STUDY POPULATION: Total of 5002 patients. OBSERVATION: Clinical features. MAIN OUTCOME MEASURE: Differentiation of benign from malignant counterparts. RESULTS: The tumor was benign (52%), premalignant (18%), or malignant (30%). Malignant tumors included melanoma (12%), squamous cell carcinoma (SCC) (9%), lymphoma (7%), and others. Comparison of primary acquired melanosis vs melanoma revealed melanoma with greater median patient age (54 vs 61 years, P < .0001), male sex (35% vs 49%, P < .0001), location in fornix (2% vs 6%, P = .0016) and tarsus (1% vs 4%, P = .0018), larger median basal diameter (6 vs 8 mm, P < .0001) and thickness (<1 vs 1 mm, P < .0001), and intralesional cysts (0% vs 7%, P < .0001), feeder vessels (10% vs 48%, P < .0001), intrinsic vessels (4% vs 33%, P < .0001), and hemorrhage (<1% vs 3%, P = .0001). Comparison of conjunctival intraepithelial neoplasia (CIN) vs SCC revealed SCC with greater diffuse involvement (1% vs 8%, P < .0001) and larger median basal diameter (7 vs 8 mm, P < .0001) and thickness (1 mm vs 2 mm, P < .0001). Comparison of benign reactive lymphoid hyperplasia vs lymphoma revealed lymphoma with greater median patient age (50 vs 61 years, P < .0001), fornix location (32% vs 54%, P < .0001), larger median basal diameter (10 vs 20 mm, P < .0001), and less involvement of nasal region (50% vs 23%, P < .0001). CONCLUSION: In an ocular oncology practice, conjunctival tumors are benign (52%), premalignant (18%), or malignant (30%). Malignant tumors tend to occur in older patients and demonstrate greater basal diameter and thickness, compared with benign counterparts. Copyright Â
