Unna Nevus: Early Presentation in a 10-Year-Old Girl

A 10-year-old girl presented with three asymptomatic raised lesions over the dorsal aspect of her left index finger present for the past 7 years. On examination, there were three skin-colored nodules overlying the middle and distal phalanx of her left index finger, without any attachment to the underlying structures (Figure 1) The nodule over the distal phalanx was the largest with a cobblestone-like surface. All the nodules were firm to touch. Cutaneous, mucosa, hair, nails, and systemic examinations were within normal limits. The two smaller nodules were excised under local anesthesia and sent for histopathologic examination. Histologic study from one of the representative lesion showed type B nevus cells (lymphocytoid), located in the expanded papillary dermis (Figures 2 and 3).
