🦠 Tinea Corporis vs Tinea Versicolor — Don’t Confuse Them in Exams!
Many nursing and medical students lose marks because they mix up ringworm (dermatophyte infection) with Malassezia infection.
⚡ Quick Exam Trick
🔹 Tinea corporis → Ring-shaped lesion with central clearing
🔹 Tinea versicolor → Hypo/Hyperpigmented macules with fine scaling
🔹 KOH test → “Spaghetti & Meatballs” appearance (Malassezia)
💡 NCLEX / NORCET / AIIMS Tip:
If the question mentions Wood’s lamp → Yellow-gold fluorescence, think Tinea versicolor.
