An 8-year-old Hispanic girl was diagnosed as having ataxia telangiectasia (AT) at the age of 2 years, when she was noted to have an unsteady gait, ataxia, and hypotonia. At the age of 4 years, she was seen at the dermatology clinic for widespread hypopigmented and depigmented patches, consistent with vitiligo. She was also noted to have bulbar conjunctival telangiectasias (Figure 1). At the age of 5 years, she was seen in dermatology because of a persistent lesion on her left cheek. On examination, she had a 2.3×3.5-cm, irregularly bordered, dusky-red plaque on her left cheek (Figure 2), as well as a similar plaque on her right ankle (Figure 3). A skin biopsy specimen was obtained from the cheek lesion (Figure 4 and Figure 5).
