Résumé
This study analysed the prevalence of the characteristics evaluated in dermatoscopy for melanocytic infiltrations of the conjunctiva with various degrees of malignancy. A total of 160 conjunctival pigmented lesions were studied. Each lesion was scored using dermatoscopic patterns and the characteristics of malignancy described by Kittler. Also, the Authors' own clues were added to the evaluation. In melanomas, the following characteristics were identified: asymmetry of the pattern and colour, larger average number of colours, the presence of grey colour, structureless area, polymorphic vessels and feeder vessels. A pattern of black dots and a black colour was typical of malignant lesions and pre-cancerous (premalignant) lesions - primary acquired melanosis (PAM) with atypia. Cysts were observed only in the group of naevi. The patterns evaluated with dermatoscopy are present in pigmented lesions of the conjunctiva. There are, however, some characteristics which allow differentiation between melanoma and pigmented naevus and melanosis and also between PAM.

BACKGROUND/AIM
OBJECTIVE
This study analysed the prevalence of the characteristics evaluated in dermatoscopy for melanocytic infiltrations of the conjunctiva with various degrees of malignancy.
PATIENTS AND METHODS
METHODS
A total of 160 conjunctival pigmented lesions were studied. Each lesion was scored using dermatoscopic patterns and the characteristics of malignancy described by Kittler. Also, the Authors' own clues were added to the evaluation.
RESULTS
RESULTS
In melanomas, the following characteristics were identified: asymmetry of the pattern and colour, larger average number of colours, the presence of grey colour, structureless area, polymorphic vessels and feeder vessels. A pattern of black dots and a black colour was typical of malignant lesions and pre-cancerous (premalignant) lesions - primary acquired melanosis (PAM) with atypia. Cysts were observed only in the group of naevi.
CONCLUSION
CONCLUSIONS
The patterns evaluated with dermatoscopy are present in pigmented lesions of the conjunctiva. There are, however, some characteristics which allow differentiation between melanoma and pigmented naevus and melanosis and also between PAM.
