Introduction Spider naevi (SN) are considered a subtype of telangiectasias, currently classified as low‐flow vascular malformations. Objective To describe the videodermoscopy and Doppler‐ultrasound (US) features of a large group of SN. Material and Methods A retrospective study of cases of SN collected at our Dermatology department during the period between June 2015 and June 2017 was performed. Clinical images, dermoscopic, videodermoscopic and Doppler‐US files were reviewed. For each case, the age of the patient, time since onset, size and dermoscopic pattern of the lesions were recorded. The presence of pulsatility was also evaluated visually on the videodermoscopy. Results Two hundred and thirty‐three SN in 189 patients were included. The mean age was 39.5 years (range: 10–76 years). Mean size of the lesions was 4.1 ± 2.0 mm. We described three dermoscopic patterns: network, star and looping. Older age, longer time since onset and larger size were found associated with higher frequency of the looping and star patterns compared to that of network pattern (P
