1. INTRODUCTION
The term telangiectasia refers to a dilated venule, capillary, or arteriole visible to the
human eye and measuring 0.1-1.0 mm in diameter (1). Telangiectasias develop on the
face secondary to genetic predisposition, chronic actinic damage, collagen vascular
disorders, topical corticosteroid application, and disorders of vascular regulation such as
acne rosacea. Linear and “spider” telangiectasias develop on the legs, especially in
women, beginning in the second to third decade due to multiple factors including
genetic predisposition, gravity, pregnancy, and trauma. Papular telangiectasias are fre-
quently seen as part of genetic syndromes, such as Osler-Weber-Rendu syndrome,
and are also seen in collagen vascular disorders (2). Spider telangiectasias typically
occur in school-age children, with most persisting into adulthood. They present a cosmetic
concern as well as the propensity to bleed with minor trauma (1).
