This work also aimed to develop an algorithm allowing the differentiation between conjunctival melanoma and other melanocytic lesions of the conjunctiva, on the basis of a dermatoscopic examination. We performed retrospective clinical and histopathological analysis of conjunctival lesions surgically treated during one year in our institution in correlation with the interview data, with special regard to the practical approach through the division into pigmented and amelanotic lesion with setting the probability of their attribution to benign, pre\-malignant and malignant ones. Material and Methodology A total of 160 conjunctival pigmented lesions \(40 naevi, 40 PAM without atypia, 40 PAM with atypia, 40 melanomas\) were studied. Each lesion was scored using dermatoscopic patterns and the clues of malignancy described by Kittler. Also, the Authors’ own clues were added to the evaluation \(black dots occuring in any parts of the lesion, feeder vessels and cysts\) All 305 patients \(164 men, 141 women\) who underwent surgical excision of conjunctival tumors in 2017 at the Department of Ophthalmology and Ocular Oncology Jagiellonian University Medical College in Krakow were analyzed."]
