Vascular Lesion
An abnormality of superficial blood vessels in the skin—such as spider veins, port-wine stains, or haemangiomas—that is commonly addressed by laser or light-based cosmetic treatments.
Full Definition
In cosmetic dermatology, 'vascular lesion' is a broad descriptor encompassing conditions including telangiectasias, spider naevi, rosacea-associated erythema, port-wine stains, haemangiomas, and cherry angiomas. Treatment typically involves selective photothermolysis using wavelengths (e.g., 532 nm KTP laser or 595 nm pulsed dye laser) absorbed preferentially by oxyhaemoglobin. Editors should be alert to inconsistent capitalisation of specific lesion types and should ensure that the named pathology (e.g., 'port-wine stain', not 'port wine stain') is hyphenated correctly per clinical style guides. The term 'vascular blemish' is used in patient-facing copy but is considered informal in clinical documentation.
Usage
Usage note: In clinical documentation, specify the type of vascular lesion rather than using the generic term alone. In patient copy, plain-English equivalents may be used with clinical terms in parentheses.
In Context
- "The treatment consent form listed 'vascular lesions' without specifying the type; the editor queried whether this should read 'telangiectasias' or 'port-wine stain'." — Patient consent form
- "In patient-facing leaflets, 'vascular lesion' may be replaced with the plain-English term 'thread vein' for clarity, with the clinical term parenthesised." — Patient education leaflet
