It’s pretty easy to figure out what DLE was about from the context clues in the article. Knowing that it means discoid lupus erythematosus and the detailed definition wouldn’t have added much imo. In fact I didn’t even care to look it up until I read your comment.

if you're referring to DLE, from the second paragraph:

> When she was diagnosed with DLE, discoid lupus erythematosus, an autoimmune condition where the immune system attacks the skin on the nose and sunlight makes it worse

edit: ah, just saw a comment from the author indicating they added that post-hoc

Sounds like someone just needs to spend more time keeping up with rare canine autoimmune disorders
