Mandy Moore’s 2-Year-Old Son Gus Is Diagnosed With Gianotti-Crosti Syndrome: ‘Crazy Rash’

Mandy Moore is giving fans an update after her 2-year-old son faced a startling health scare. On Friday, the “This Is Us” actress took to Instagram to explain that little Gus woke up last weekend with an alarming skin condition. “This sweet boy woke up with a crazy rash on Saturday am. We thought maybe an excema flare? Poison oak? Allergy. We tried to deduce what it could be and did anything to help him find relief from the itch. Went to urgent care. Pediatrician. Dermatologist. Pediatric dermatologist. All the while, he smiles and laughs and carries on with his day like the rockstar he is.” She went on to reveal that the tot is on the mend and explained what he was diagnosed with. “Turns out it’s a viral childhood rash that just spontaneously appears called Gianotti-Crosti syndrome. It sometimes accompanies a cold but not in Gus’s case. 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. 0oooof. Anyone else ever experience this??” she added.
