[Erythematotelangiectatic skin--diagnostic difficulties]

Erythematotelangiectatic skin is a common cosmetic and medical problem. Flushing or persistent erythema, teleangiectasias, and occasionally other inflammatory skin lesions can be caused by internal or environmental factors. Certain physiologic reactions and systemic or dermatologic diseases represent internal conditions leading to visible skin flushing in the blush area. Erythematotelangiectatic skin is found in body areas which are particularly exposed to various environmental factors and perform important esthetic functions at the same time. Determination of the main etiopathologic factor responsible for flushing in the blush area precedes the selection of an adequate method of care, correction or treatment of the erythematotelangiectatic skin. The main aim of this study was to analyze fundamental mechanisms of flushing or persistent erythema and their sequellae basing on the literature. Another aim was to review current diagnostic options useful in examining the etiology and severity of erythematotelangiectatic skin symptoms.
