Unilateral nevoid telangiectasia presents with fine thread veins, typically over a segment of skin supplied by a particular nerve on one side of the body. [1] It most frequently involves the trigeminal, C3 and C4, or nearby areas. [1] The condition was named in 1970 by Victor Selmanowitz. [2]
Unilateral nevoid telangiectasia is characterized by multiple chronic asymptomatic superficial blanching telangiectasias along dermatomes or Blaschko's lines, [3] with asymmetric skin involvement, [4] while symmetric instances have been infrequently recorded. [5] [6] The trunk and upper extremities' third and fourth cervical dermatomes are the most severely impacted. [4]
Unilateral nevoid telangiectasia can be congenital or acquired. Rare congenital type manifests at or soon after the neonatal period; it is more common in males and occurs in an autosomal dominant pattern. Conversely, the acquired form is nearly exclusively found in young female patients who have physiologic problems. [7]
A normal-appearing epidermis with superficial dermal telangiectatic blood vessels beneath and a low level of inflammatory infiltration is revealed by histopathologic investigation. [8]
After the triggering factor is eliminated, unilateral nevoid telangiectasia usually persists but in rare situations, it resolves on its own. The first step in treatment is cosmetic concealment. [7] The condition has improved aesthetically with the use of pulsed dye laser, which has proven to be a useful alternative. [9]
