Cómo decía mi amigo el Dr. HOUSE , nunca es lupus!
Not everything with “lupus” is ! 🐺❌
Some diseases carry the name but have nothing to do with systemic lupus erythematosus ( ). Let’s clear the confusion
1️⃣ Lupus vulgaris
➡️ Chronic cutaneous TB 🦠
➡️ Painful nodules & ulcers, often disfiguring (“wolf-bite” scars)
2️⃣ Lupus pernio
➡️ Chronic sarcoidosis of the skin
➡️ Violaceous plaques on nose, cheeks, ears
3️⃣ Lupus miliaris disseminatus faciei (LMDF)
➡️ Rare granulomatous papules, esp. around eyelids/mid-face
➡️ Heal with pits/scars
4️⃣ Lupus anticoagulant
➡️ A misnamed autoantibody
➡️ Causes clotting + pregnancy loss (Antiphospholipid Syndrome)
🚫 Over half of patients don’t even have lupus!
So next time you hear “lupus”, remember:
👉 Sometimes it’s TB, sarcoid, granulomas, or antibodies — but not lupus erythematosus!
Names confuse, diseases don’t connect.
