🔍 Quick Summary
Pityriasis versicolor is a common fungal skin condition that causes light or dark patches.
It is harmless but can affect appearance—and is treatable.
1️⃣ Introduction
Pityriasis versicolor is a superficial fungal infection of the skin.
• caused by yeast naturally present on the skin
• leads to uneven skin color (patches)
• not dangerous but can be persistent
👉 It affects pigmentation—not deeper skin layers.
2️⃣ How it happens
The yeast on the skin grows excessively.
• disrupts normal pigment production
• causes lighter or darker patches
• more noticeable after sun exposure
👉 The fungus interferes with how the skin produces color.
3️⃣ Types
• Hypopigmented patches
- lighter than surrounding skin
- common in darker skin tones
• Hyperpigmented patches
- darker or slightly pink/brown
- may vary with skin type
👉 Appearance depends on individual skin tone.
4️⃣ Common causes
• Overgrowth of yeast (Malassezia)
• Contributing factors
- hot, humid weather
- oily skin
- sweating
5️⃣ Symptom explanation
• patches on chest, back, neck, or arms
• color changes (lighter or darker)
• mild scaling
👉 These occur due to disrupted pigment and surface fungal growth.
6️⃣ Associated symptoms
• mild itching (sometimes)
• fine dry scaling
• patches more visible after sun exposure
• gradual spread
👉 Often more noticeable than physically uncomfortable.
7️⃣🩺 When it becomes concerning 🚨
• widespread patches
• no improvement with treatment
• uncertainty about diagnosis
👉 These may indicate:
• need for medical confirmation
• alternative skin condition
8️⃣ Management / treatment
• antifungal creams or shampoos
• oral antifungal medication (if extensive)
• maintaining skin hygiene
9️⃣ Diagnosis
• clinical examination
• skin scraping (if needed)
