Rapidly growing nodule on infant’s posterior thighThe parents of a healthy 5-month-old boy bring him to the office for evaluation of an enlarging yellowish nodule on the back of his right thigh. It started as a pink macule several months ago and became yellow and lumpy over the last month. The infant was born at term and has grown and developed normally. His parents deny any trauma, but report occasional bleeding from the surface of the nodule. They deny any new medications or outdoor exposures. There is no history of new topical skin products.
