A healthy 6-year-old boy presents for evaluation with a 3-month history of an asymptomatic rash extending from his left thumb to his left wrist. What's the diagnosis?
A healthy full-term newborn presented with a prominent sacral dimple within an oval patch. Ultrasound showed no evidence of spinal anomalies, and the child was discharged home. Three days later, the patch became elevated, red, and moist appearing, and she was brought to the emergency department (ED) for further evaluation of the “growing blister.”
