What Is a Mycosis?


Mycosis is a fungal infection that affects the skin, nails, or between the toes and fingers. It’s caused by microscopic fungi — mainly dermatophytes, yeasts (Candida), or molds   that thrive in warm, moist environments such as shoes, socks, or public showers.

When these fungi grow uncontrollably, they can cause irritation, itching, and even nail damage.

 Common Types of Fungal Infections on Toes and Fingers

1. Athlete’s Foot (Tinea pedis)

One of the most frequent foot infections, usually between the toes.

Symptoms:

  • Itching and burning sensation

  • Peeling, cracked, or white skin between toes

  • Unpleasant odor

Causes:

  • Wearing tight or non-breathable shoes

  • Walking barefoot in humid public areas (pools, gyms)

  • Excessive sweating

2. Nail Fungus (Onychomycosis)

A chronic infection that affects toenails or fingernails.

Symptoms:

  • Thickened, yellow or brown nails

  • Brittle and fragile nail texture

  • Nail detachment or foul odor

Causes:

  • Untreated athlete’s foot

  • Poor foot hygiene

  • Humid conditions or sharing nail tools

3. Hand Mycosis (Tinea manuum)

Less common but similar to athlete’s foot, it affects the hands, especially in people who touch infected feet or objects.

Symptoms:

  • Red, dry, scaly patches on palms or between fingers

  • Itching and cracking skin

  • In some cases, nail involvement

Diagnosis

To confirm a fungal infection, doctors may perform:

  • Microscopic examination of skin or nail scrapings

  • Culture tests to identify the fungal species

  • Wood’s lamp or PCR tests for specific identification

 Treatment Options

Fungal infections require consistent and targeted treatment to avoid recurrence.

 Topical Treatments:

  • Antifungal creams or sprays: clotrimazole, terbinafine, or miconazole

  • Antifungal powders: to keep feet dry and prevent spread

 Oral Treatments:

  • Itraconazole or fluconazole for deeper or persistent infections

  • Nail lacquer with antifungal agents (ciclopirox, amorolfine)

 Natural Remedies (supportive care):

  • Tea tree oil: natural antifungal properties

  • Vinegar or salt foot baths: may help control mild infections
