How to recognize the type of onychomycosis in the photo?

How do you know if you have nail fungus and which one? Ideally, you need to see a doctor for an accurate diagnosis. But if there is an urgent need to understand this problem, our selection of photos with a description of the symptoms will help, focusing on how you can understand what type of onychomycosis you suffer from.

how to recognize fungus on toenails

It is not enough to diagnose nail fungus - it is important to accurately determine the type of pathogen, the stage and form of the disease. Doctors use several diagnostic methods for this, and patients can recognize which specific onychomycosis has hit them, thanks to the characteristic symptoms and photos of nails affected by the fungus.

Photo of nail fungus at various stages of development

Initial stage

The first symptoms of the disease appear as follows:

  • changes in nail color and skin around the nail plate;
  • the appearance of yellow and white dots, longitudinal stripes, microcracks, spots, rough skin;
  • the nail plate changes its structure, becomes rugged, thin, loose and brittle.

Second stage

In the second stage, the fungus begins to actively divide and the symptoms of an unpleasant disease begin to blossom literally before our eyes. The nail thickens and darkens, deforms, becomes brittle, with time deep cracks appear.

Third stage

The advanced stage of damage to the nail plate is manifested by its thickening or pathological thinning. A strong thickening of the nail plate is a protective reaction of the body. By the density of the stratum corneum, you can determine how deep the fungus has penetrated the nail.

When the fungus does its job and the thinner nail plate is rejected by the body as a source of infection, the fungus spreads to the nail bed. This is fraught with a purulent process and susceptibility to various infections.

Photo of onychomycosis in different variants of the disease course

Dermatologists identify different variants of the disease course. One look at the legs is enough for a specialist to make the diagnosis.

Normotrophic flow variant

It has the following resources:

  • the thickness of the nail is preserved, which indicates the location of the infection in the upper layers;
  • The
  • nails are dense, not brittle;
  • presence of yellow or white spots in the form of spots and stripes;
  • the edge of the affected nail is irregular and serrated.

The prognosis of treatment in this case is favorable. Until thickening appears, the nail can be saved quickly.

Hypertrophic course

Has the following symptoms:

  • the deformation of the nail plate is visible to the naked eye;
  • the nail is crumbling;
  • color of the dish is gray, dirty yellow, brown, lacking natural luster;
  • hyperkeratosis, manifested by increased growth of corneal cells from the plaque upwards, which causes discomfort when walking, painful sensations.

In most cases, hyperkeratosis is the main reason for seeking medical attention.

atrophic variant of the disease course

Atrophic variant of the course

It is characterized by the following features:

  • the nail is thin, gray or brown;
  • nail plate rejection.

In this case, the treatment is very difficult, the hopes of restoring the nail plate are minimal and the risk of the nail completely atrophy is high.

Photo of fungus on the nails depending on the pathogen

There are three types of fungi that infect the nail plate.


They can be recognized by the following symptoms:

  • nail blade deformation;
  • the appearance of streaks, spots, turbidity of the nail;
  • nail malnutrition and mold damage are manifested by the appearance of brown and black spots;
  • redness and inflammation of the nail skin.

Yeast mushrooms

It has the following resources:

  • the nail has become thinner and looser;
  • the periungual area is usually inflamed;
  • injury of interdigital folds and feet.

Those in constant contact with water are susceptible to infection with this pathogen.


They differ in the following characteristic symptoms:

moldy appearance of fungus on the nails
  • changes the color of the plate to green, black, gray;
  • the fungus can develop after a finger touch;
  • The
  • mold does not penetrate deeply into the nail.

Photo of onychomycosis depending on the form of the disease

The onset of negative manifestations in different cases begins at a specific location on the nail plate.

Distal variant

Your attributes:

  • onset of infection of the free limit;
  • the edge of the nail becomes white or yellowish;
  • the infection gradually grows from the border to the center.

Lateral (lateral) variant

Has the following symptoms:

  • begins on the sides of the nail in the skin fold;
  • The colonies of the fungus, moving laterally in each other, quickly spread the disease, covering the entire surface of the nail.

Proximal variant

Characterized by the following manifestations:

  • the disease starts on the side of the cuticle;
  • Gradual penetration of the fungus from the beginning of the nail to the edge, which leads to the appearance of spots, thinning of the plaque.

White surface

Has the following clinical picture:

  • can appear anywhere on the nail plate;
  • rapid development and distribution;
  • due to the defeat of the upper layer, the nail appears to be covered with a white powder;
  • without thickening.

Total variation

Symptoms of this nail fungus:

total variant of the fungus on the nails
  • extensive spread of infection from the free edge of the nail and cuticle;
  • inflammation of the nail fold;
  • thinning or hyper-thickening of the plate;
  • fragility.

The reasons for such a rapid course may be improper treatment or lack thereof, as well as a significant weakening of the body's immune system.

The fight against nail fungus must be started with the knowledge of it. Thanks to this selection of photos, you will be able to independently determine the causative agent, the location and the severity of onychomycosis.
