Two patients present with red lesions. A white infant aged 4 months presented with a three-month history of a red, verrucous nodule on his scalp, that grew from a small papule to a 3-cm nodule. A white man aged 50 years who had developed red papules on his legs, arms, chest and abdomen 20 years earlier, noticed that a group of the papules grew together to form a plaque. Can you differentiate between these two patients’ lesions?
