Case Presentation

 A 40-year-old woman presented to the dermatology clinic 

after pregnancy for new-onset of asymptomatic patches 

of superficial telangiectasia, partially blanchable, mostly 

arranged unilaterally on the right side of her upper body, 

including neck, shoulder, and arm. Lesions also involved 

bilaterally the cervical dermatomes on the chest (Figure 1A). 

Dermoscopy showed ectatic, tortuous, and thin capillaries 

(Figure 1B). 

Diagnosis of unilateral nevoid telangiectasia (UNT) was 

made upon clinical and dermoscopic findings.

Teaching Point

UNT is a rare, nevertheless underdiagnosed, and underre-

ported capillary malformation, associated with increased 

estrogen levels [1]. It may have a striking appearance, but 

patients should be reassured about the benignity of the con-

dition [2].
