Unilateral Nevoid Telangiectasia in a Female Adolescent: A Case Report

Unilateral nevoid telangiectasia (UNT) is a rare, benign vascular disorder characterized by superficial, arborizing telangiectasias distributed unilaterally within a single body segment. The acquired form is the most frequent and is more common in adolescents during puberty and in women of childbearing age, possibly due to estrogen-related mechanisms. Although its true prevalence remains unknown, UNT is believed to be underdiagnosed due to its subtle and often asymptomatic nature. Diagnosis is primarily clinical; however, skin biopsy can assist in confirming the diagnosis and excluding other vascular or dermatologic conditions. We present a case of UNT in a 10-year-old adolescent female, along with a review of the current literature.
