If you’re a Mandy Moore fan, then chances are you saw her Instagram story detailing how her two-year-old son August, also known as Gus, was recently diagnosed with a rare skin condition known as Gianotti-Crosti syndrome.

She revealed the news on July 28 in photos obtained by Page Six, with a photo that started by saying: “This sweet boy woke up with a crazy rash on Saturday am,” and how she thought it was a spontaneous rash that came out of nowhere.

But after some digging, they found the culprit, saying, “Turns out it’s a viral childhood rash that just spontaneously appears called Gianotti-Crosti syndrome. It sometimes a company’s 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 to 8 weeks.”
