Okay, it's not. It's just a weird rash that has nothing to do with hygiene, moral fortitude, or coal, and just happens to be kind of in the shape of a Christmas tree. If you're really bad at identifying shapes. But I guess "blob rash" isn't particularly evocative.
Let's learn about it anyway, shall we?
It may start with a sore throat. After that, there's the aptly-named "herald" patch, a round or oval pink patch that usually shows up on the chest or abdomen, then fades. Days or weeks later, the pink dots start. Sometimes they're on the front, sometimes the back.
And what's really weird is their pattern.
"It was like a tattoo that covered my back in the shape of a Christmas tree," says Mark Jared Zufelt, a 41-year-old Seattle writer/director/photographer, who came down with the rash in his 20s. "It fanned out from the top and worked its way down. It was gross."
...Itchy and scaly (each pink dot is covered with a thin white scale, like cigarette paper), the rash is fairly common and sometimes confused with ringworm, eczema or psoriasis.
However, the article notes, it is possible to have a reaction to your Christmas tree if you're a
filthy Grinch who hates America person who happens to have allergies:
In 2007, a British teacher named Nicola Coleman made headlines when she broke out in red hives shortly after putting up a Norway spruce. Researchers have also found that some people are allergic to the mold found in pine or fir trees. They've dubbed this allergy — which triggers a runny nose, sneezing and asthma attacks — Christmas tree syndrome.
