Abstract: Background: In general, classification of warts is based on morphology, histology, and anatomic location. Diagnostic accuracy can be improved by dermoscopy examination comparison to the naked eye. There are only few studies about dermoscopic findings in cutaneus warts. Case: We presented 6 cases of verruca vulgaris, palmaris and filiformis with dermoscopy examination. All cases had warts with various location and morphology, there are location in hands, finger and foot. The dermoscopic aspects in verruca vulgaris were based on the presence of verrucous, greyish structureless surrounded by whitish halos and irregularly distributed multiple punctate haemorrhages; frogspawn appearance. In verruca palmaris, we found a well-defined yellowish papilliform surface with interrupted palmaris lines and multiple punctate haemorrhages was observed. Whereas on verruca filiformis, finger like papilliform structure and hairpin vessel. Discussion: Dermoscopic findings in different type of warts can be varied. Multiple punctate haemorrhages; red, brown or black dot are the most common dermoscopic finding that can be observed in all cases of warts.
