1️⃣ Introduction

Tinea corporis is a superficial fungal infection of the skin.

• affects the body (arms, legs, trunk)
• caused by dermatophyte fungi
• commonly called “ringworm” 

πŸ‘‰ The name comes from the ring-shaped rash—not an actual worm.

2️⃣ How it happens

Fungi infect the outer layer of the skin.

• thrive in warm, moist environments
• spread on the skin surface
• feed on keratin (skin protein)

πŸ‘‰ The infection remains on the surface but can spread outward.

3️⃣ Classification

• Localized tinea corporis

  • single or few patches
  • mild infection

• Widespread tinea corporis

  • multiple areas involved
  • may need stronger treatment

πŸ‘‰ Extent determines treatment approach.

4️⃣ Common causes

• Direct contact

  • skin-to-skin with infected person
  • contact with animals (e.g. pets)

• Indirect contact

  • shared towels, clothing
  • contaminated surfaces

5️⃣ Symptoms

• circular or ring-shaped rash
• red, raised edges
• clearer center

πŸ‘‰ The rash spreads outward, forming a ring pattern.

6️⃣ Associated symptoms

• itching
• scaling or dry skin
• gradual spread
• mild discomfort

πŸ‘‰ Scratching can worsen and spread infection.

7οΈβƒ£πŸ©ΊWhen it becomes concerning 🚨

• multiple areas affected
• no improvement with treatment

πŸ‘‰ These may indicate:
• more extensive infection
• need for medical treatment

8️⃣ Management / treatment

• oral antifungals if widespread
• keep skin clean and dry

9️⃣ Diagnosis
