Derm Dx: Linear, streaky vesicles at birth
An infant in the pediatric clinic has been exhibiting interesting skin findings. At birth, she had a linear and streaky distribution of vesicles on her trunk and extremities, which subsequently progressed to verrucous plaques at age 2 months and hyperpigmented streaks at age 5 months.
The infant appears to have a small patch of alopecia at the scalp crown. The patient underwent an MRI after birth, which demonstrated that she likely had a small right frontal stroke, but otherwise she is neurologically intact.
An ophthalmologic examination is normal. The patient’s CBC and complete metabolic panel after birth were significant only for a peripheral eosinophilia. An examination of the mother demonstrates pigmented streaks on the trunk and leg (image below).
