Dermoscopy as an Important Tool for Differentiating Unilateral Nevoid Telangiectasia and Angioma Serpiginosum

Focal cutaneous telangiectasia in a young dog of probable congenital origin

“…In our case, the rather young age of presentation of the lesion in our case may suggest a congenital disorder, and the clinical and histopathological findings were similar to those of UNT. Dermoscopy showed a reticulated appearance with tortuous vessels, which suggested dilated capillaries in the superficial layer of the dermis; these findings were also similar to the dermoscopic findings of UNT (Küçük et al., 2021 ; Villela‐Segura, 2019 ). Although dermoscopy is a useful non‐invasive tool for the examination of vascular lesions in humans, there are no reports on its use in animals for examining vascular lesions (Dong et al., 2016 ; Genovese et al., 2014 ; Scarampella et al., 2015 , 2017 ; Tomich et al., 2018 ; Zanna et al., 2015 , 2017 ).…”

“…It is suspected that the lesion appeared during the neonatal periods due to a non‐progressive nature in the dog. Primary telangiectasias have a good prognosis, with the exception of aesthetic considerations (Goldsmith et al., 2015; Küçük et al., 2021; Villela‐Segura, 2019). Cutaneous telangiectasia in dogs has been associated with Cushing's syndrome (Gross et al., 2005).…”

Dermoscopic Analysis of Vascular Malformations and Tumors Based Upon Dominant Vascular Dermoscopic Features: A Retrospective Analysis From a Tertiary Care Center of East India

“…The dermoscopic features of AS were dominated by short linear and linear irregular vessels of variable diameter that had ill-defined margins/blurred margins (Figure 2E) and were arranged in a haphazard arrangement. Additional dermoscopic features described before are hairpin-like and comma vessels [10]. In line with the prior report, in all subtypes of AK, the prominent dermoscopic features were red, reddishpurple to brown-black lacunae (Figure 3A) [11,12].…”

Unilateral Nevoid Telangiectasia

“…Dermoscopy shows multiple tortuous capillaries in reticulated pattern. [ 4 ] Histopathological examination shows dilated vessels in upper dermis without any endothelial cell proliferation or angiogenesis. Management mainly includes treating the primary cause of hyperestrogenemia and reassurance for the skin condition.…”
