Laboratory Studies

The following laboratory tests may be necessary:

  • Serum pregnancy test, if applicable
  • Liver function tests
  • Hepatitis profile

Individual case reports have described unilateral nevoid telangiectasia in association with other systemic abnormalities. However, the evidence is minimal at this time for such associations, and, therefore, screening has not been recommended. Such associations include a case of unilateral nevoid telangiectasia associated with hyperthyroidism[7] and a case of unilateral nevoid telangiectasia occurring in a hepatitis B carrier without evidence of liver dysfunction.

Other Tests

Punch biopsy of lesional and perilesional skin for comparison may be considered. Skin biopsy is usually not necessary because the diagnosis is usually established on clinical grounds.

Other testing is not necessary. However, Kreft et al have described the results of laser-Doppler flowmetry in a patient with unilateral nevoid telangiectasia.[8] They were able to demonstrate increased perfusion in areas of unilateral nevoid telangiectasia, even in areas that were clinically unremarkable. They also found that capillary microscopy demonstrated morphologically altered capillaries.
