Dermatoses Resulting from Disorders of the Veins and Arteries

Abstract

This chapter discusses the disorders that affect the arteries and veins that are important to practising dermatologists. It moves from peripheral arterial disease to varicose veins, venous thrombosis and chronic insufficiency. On the way, arterial, venous and arteriovenous malformations are discussed; the types and causes of telangiectases are described; and erythromelalgia is covered. The latest on the pathogenesis of these disorders is discussed and the most recent guidelines on management are given.

Focal cutaneous telangiectasia in a young dog of probable congenital origin

“…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).…”

“…Several subtypes of telangiectasia have been discussed, and some of them may be reclassified in the future. Congenital unilateral naevoid telangiectasia (UNT) is presumably involved in the ISSVA (2018) (Calonje et al., 2015; Goldsmith et al., 2015; Cossiolo et al, 2018; Küçük et al., 2021). It presents at birth or shortly after neonatal periods and is characterised by clustered telangiectasia with a reticular appearance that blanches with diascopy.…”

“…We present a young dog with focal cutaneous telangiectasia based on clinical (including dermatoscopy) and histological features. Telangiectasia is defined as the permanent dilatation of pre‐existing blood vessels, creating small focal lesions, usually in the skin or mucous membranes (Demanuelle et al., 1999; Goldsmith et al., 2015).…”

“…Cutaneous vascular anomalies form a heterogeneous disease group that would be categorised into tumours and malformations in human medicine according to clinical and biological criteria (Calonje et al., 2015; Dompmartin et al., 2015; Goldsmith et al., 2015; ISSVA, 2018). A new classification (International Society for the Study of Vascular Anomalies [ISSVA], 2018) for human vascular anomalies has been proposed in 2018 by the ISSVA.…”

Surgical excision and primary closure of venous lake of upper eye lid for better cosmetic outcome: A case report

“…Usually, they are single in number but occasionally multiple lesions can occur. [ 1 ] Histologically, they are lined by a single layer of flattened endothelial cells and a thick wall of fibrous tissue is located in the upper dermis. The lesion is thought to occur as a result of the deterioration in connective tissue in vascular adventitia and in the dermis.…”
