Tinea Corporis

Tinea corporis is a common superficial fungal infection of the glabrous (non-hairy) skin. Characterized by itchy, erythematous, annular lesions with a scaly, advancing border and central clearing, it is caused by dermatophyte fungi that inhabit the stratum corneum.

It is caused by anthropophilic, zoophilic, or geophilic dermatophytes, primarily Trichophyton rubrum, Trichophyton mentagrophytes, and Microsporum canis. Transmission occurs via direct skin-to-skin contact, fomites (towels, clothing), or zoonotic contact with infected pets.

Dermatophytes secrete keratinases, enzymes that digest keratin, allowing the fungus to colonize the stratum corneum. The host immune response, primarily cell-mediated immunity, results in inflammation, scaling, and the classic annular appearance as the fungus expands radially from the site of inoculation.

Global prevalence is high, particularly in warm, humid climates. It affects all ages but is more common in children and young adults. Males are slightly more susceptible than females due to higher levels of physical activity and sports participation.

• Hyperhidrosis (excessive sweating)
• Immunocompromised state (e.g., HIV, diabetes, systemic corticosteroids)
• Direct contact with infected pets
• Living in hot, humid environments
• Participation in contact sports (e.g., wrestling)

A. Early Symptoms

• Small, red, pruritic papules or vesicles


• Mild localized erythema B. Common Symptoms


• Annular (ring-shaped) erythematous lesions


• Scaling at the advancing border


• Central clearing


• Pruritus C. Advanced Symptoms


• Coalescence of multiple rings


• Pustules or crusting along the border


• Hyperpigmentation or hypopigmentation (post-inflammatory) D. Emergency Symptoms


• Secondary bacterial cellulitis (fever, spreading warmth, pain)

Physical findings reveal distinct, circular patches with raised, scaly borders. The center is often hypopigmented or clear. Palpation may reveal induration at the border.

A. Clinical Assessment: Typically visual inspection is sufficient.
B. Laboratory Testing: Potassium hydroxide (KOH) mount of skin scrapings.
C. Imaging Studies: Wood’s lamp examination (generally negative for tinea corporis).
D. Functional Tests: None.
E. Biopsy Findings: Periodic Acid-Schiff (PAS) stain reveals fungal hyphae in the stratum corneum.
F. Genetic Testing: Not indicated.
G. Differential Diagnosis: Eczema, Psoriasis, Pityriasis rosea, Granuloma annulare.

Test Name: Potassium Hydroxide (KOH) Preparation
Type: Skin scraping microscopic exam
Purpose: To visualize fungal elements (hyphae/spores).
Expected Findings: Septate, branching hyphae.
Interpretation: Diagnostic for dermatophytosis.

None standard. Wood’s lamp may be used to rule out tinea capitis.

• Psoriasis: Usually silver scaling, no central clearing.
• Pityriasis Rosea: "Herald patch," Christmas tree distribution.
• Eczema (Nummular): No central clearing, usually intensely pruritic.

• Secondary bacterial infection (e.g., Staphylococcal impetigo).
• Majocchi’s granuloma (deep folliculitis).
• Persistent pigmentary changes.

A. Lifestyle Modifications: Keep skin clean and dry. Avoid shared personal items.
B. Preventive Measures: Treat infected pets, practice good hygiene.
C. Medical Treatment:

• Topical Antifungals: Terbinafine, Clotrimazole (1st line).


• Oral Antifungals: Oral Itraconazole or Terbinafine for refractory cases.

Excellent. Most cases resolve with topical therapy within 2–4 weeks.

Avoid direct skin-to-skin contact with infected individuals; ensure gym mats are disinfected; avoid sharing clothing or towels.
