A 3-month-old infant presents to the pediatric dermatology clinic with a solitary lesion on the left lower leg. At birth the parents noticed a slightly erythematous area. There was no significant past medical history; milestones were normal.
Intermittently this area will form a superficial blister that will cover the majority of the surface area of the lesion; the blister will rapidly rupture to form a scab. At a one point she was diagnosed with a superficial bacterial infection after culturing Moraxella spp. from the area.
The blistering did respond to topical antibiotics, but a well-demarcated 1 cm x 2 cm erythematous plaque remains (Figures 1 and 2).
A diagnostic biopsy is shown in Figure 3. A stain for CD117 is shown in Figure 4.
