Mandy Moore Reveals Her Son Has Rare Skin Condition

Mandy Moore has revealed that her two-year-old son Gus has developed a rare skin condition that lasts at least 10 days. On Friday, July 28th, the This Is Us star took to her Instagram Story to share photos of a large rash that spread on her son's body.

“This sweet boy woke up with a crazy rash on Saturday am. We thought maybe an eczema flare? Poison oak? Allergy,” she wrote alongside the photo. “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 carries on with his day like the rockstar he is.”

According to the National Institutes of Health, "Gianotti Crosti syndrome (GCS) is a rare childhood skin condition characterized by a papular rash with blisters on the skin of the legs, buttocks, and arms. Skin lesions typically last at least 10 days and often last for several weeks."

Moore went on to reveal, "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’ case. It’s all over his legs and feet 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.”

The star also shared a vulnerable and encouraging note on parenting. Moore shares two sons with her husband Taylor Goldsmith. “This parenting thing is weird and hard and sometimes you feel so helpless (and yes I’m ever so grateful it’s only an itchy skin condition)," she wrote. "Kids are resilient and as long as he’s smiling through it, we are a-okay."
