Mandy Moore has revealed that her young son has a rare condition called Gianotti-Crosti syndrome.
Moore, the star of This Is Us, shared a number of photos showing her son with rashes down his legs and praised the two-year-old’s brave attitude to the illness, which could last for a few weeks.
The 39-year-old wrote: “This sweet boy woke up with a crazy rash on Saturday AM.

“We thought maybe an eczema 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 continued: “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.

“Anyone else ever experience this?
“This parenting thing is so weird and hard and sometimes you feel so helpless (and yes I'm ever so grateful it's only an itchy skin condition).
“Kids are resilient and as long as he's smiling through it, we are a-okay.”
Gianotti-Crosti syndrome - GCS - is a rare condition that comes on suddenly, sometimes accompanied by a cold, and is characterised by lesions on the skin, and a blistery rash that can appear on the arms, legs, and buttocks.
The illness can last for a few weeks, but does usually subside pretty quickly.

Not that quickly if you’re suffering with it, right enough.
The lesions on the skin are often preceded by an infection, usually a virus, which might cause problems like a sore throat, a bit of a fever, or the symptoms of an upper respiratory infection.
In some cases, the illness can be associated with Hepatitis B, though - as the US government’s rare diseases advice notes - ‘while in many countries the underlying cause [of GCS] is Hepatitis B, this is rarely the case in North America’.
Moore is known for her work as a singer, as well as starring in movies and TV shows alongside her musical career.
Currently, she stars in This Is Us, and was even nominated for a Golden Globe and a Primetime Emmy for her role as Rebecca Pearson on the family drama.
