#MandyMoore shares that her 2 year-old son Gus is on the mend after experiencing a “crazy rash” that initially seemed to have no explanation: "Turns out it's a viral childhood rash that just spontaneously appears called Gianotti-Crosti syndrome."⁠ ⁠ She says it's all over his "legs and feet (ouch) and the backs of his arms but nowhere else. There's nothing to do but a steroid cream and Benadryl at night. And it could last 6-8 weeks."⁠ ⁠ According to the National Institutes of Health, the most common symptom associated with #GionottiCrosti syndrome is a rash with blisters on the skin of the legs, buttocks, and arms. ⁠ ⁠ Link in bio for the photos Moore posted of the condition.⁠ ⁠ ✏️: Yahoo Life⁠ 📷: Getty
