Girl, nine, is forced to wear a panda onesie to school after developing an allergy to her uniform

A girl often has to wear a onesie to school because she is ‘allergic to her uniform’.

Lily Mason, from Keyworth, Nottingham, suffers from Mast Cell Activation Disorder, which sends her immune system into ‘overdrive’.

Last October, the nine-year-old was left in ‘immeasurable pain’ when her school uniform caused her to break out in a burning rash that covered her body.

Her mother, Joy Mason, 33, was forced to send Lily to school in a furry panda onesie because it was the only thing that did not irritate her skin.

As well as her school uniform being a trigger, Lily’s allergies means she ‘almost lives in a bubble’ and can only eat nine foods.

Speaking of Lily’s reaction to her uniform, Ms Mason said: ‘Her skin was beyond sore – causing her immeasurable pain.

‘Certain fabrics can affect her skin, but because her condition changes so often, it’s impossible to keep track. One day it’ll be fine, but another it won’t.’

Lily is forced to take medication every day to reduce the severity of her reactions and even has to sit on special cushions due to certain fabrics being a trigger.  

‘One day she can be allergic and the next she’ll be allergic to something else,’ her mother said.

Ms Mason, who is also mother to seven-year-old Harry, said: ‘It’s a total change from how I thought a family would be.

‘Our life is making sure Lily is as well as possible. And if that means she has to attend school wearing a onesie, so be it.’

WHAT IS MAST CELL ACTIVATION DISORDER?

Mast cell activation disorder is the umbrella term for a spectrum of diseases caused by the inappropriate activation or build-up of mast cells in the body’s tissues.

Mast cells are produced in the bone marrow and are an important part of the immune system and help fight infection.

When mast cells detect an allergen, they release histamine and other chemicals into the bloodstream. Histamine makes the blood vessels expand and the surrounding skin itchy and swollen.

Mast cells sometimes mistake harmless substances, such as pollen, for infectious germs, and trigger the process of swelling.

This can cause the skin to become red, swollen and itchy, and it can also create a build-up of mucus in the airways, which become narrower.

People with the condition have an increased risk of having a severe and life-threatening allergic reaction called anaphylaxis.

Symptoms include itchy skin or a raised, red skin rash, feeling light-headed or faint and swelling of the throat, mouth and tongue which can lead to breathing difficulties.

Lily was diagnosed with MCAS in 2017 after years of doctors being baffled by her fluctuating symptoms. 

‘When she was diagnosed, the GP didn’t even know what the condition was,’ Ms Mason said.  

‘Her immune system is in overdrive,’ she explained.

‘It was only recognised as an illness since last year but it seems everything acts as a trigger. From food to smells, Lily lives almost in a bubble.’

Due to her only being diagnosed relatively recently, Lily’s family are still adapting to her disorder.

‘We are still discovering what Lily’s triggers are and we’ve learnt she’s had the potential to be allergic to anything,’ Ms Mason said.  

‘With everything from anaphylaxis to itchy skin, to nose bleeds and fatigue, it seems Lily is constantly uncomfortable.  

‘Sometimes she’ll beg me to make the reactions stop. She’s a tough cookie though.’

MCAS is genetic with Harry having a 76 per cent chance of developing the condition. But he has shown no signs of the disorder yet. 

‘It’s a condition that can appear at any point in a person’s lifetime,’ Ms Mason said.  

‘Because it’s so hard to diagnose, it’s impossible to know how many people have it.’
