A 4-year-old boy presented with a pink nodule on his left cheek. The lesion started as a hyperpigmented macule 3 years ago and since then had been gradually increasing in size and developing into a pink nodule. The lesion was pruritic at times and sometimes bled with minor trauma. The boy was otherwise healthy, with an unremarkable medical history and with no history of trauma or exposure to radiation. On physical examination, there was a 1-cm well-circumscribed, symmetrical, pinkish, dome-shaped nodule with central erosions on the left cheek (Figure 1). Hair, nails, and mucosae were of normal appearance, and the remainder of the examination was unremarkable.
