Dermatologists will always call it rosacea so I'm not surprised. Especially since a rosacea diagnosis requires no tests. It's what I call the "easy answer". All it takes is having a red face and bam, you're slapped with a rosacea diagnosis. Three dermatologists I've been to all diagnosed me with rosacea whereas the rheumatologists I see are more fixated on Lupus and Mixed Connective Tissue Disease because all of my other symptoms that accompany my red face. Technically you can have both, but my skin doesn't respond to any of the rosacea creams. It responds better to immunomodulatory medications.

Ask dermatologist to biopsy your rash. He really should have done it in the first place when trying to determine lupus.

Mine spread from my face down my upper arms and down to ribs. It was embarrassing to me and puzzling to the doctors, but was finally diagnosed 7 months later. My mom first broke out on back of her neck, then above her eyebrows, then the butterfly across her face a year later. Took her 2 years to get a diagnosis.

It could be both. I've only heard about the butterfly rash being on the face. However for the pass few years I've been getting a rash on both of my forearms. My doctor wants me to see a dermatologist about it. But since them my rheumatologist has diagnosed me with Lupus.
