How to recognize the type of onychomycosis from the photo?

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

how to recognize toenail fungus

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

Photo of toenail fungus at different stages of development

Initial phase

The first symptoms of the disease appear as follows:

  • changes in the color of the nail and skin around the nail plate;
  • appearance of yellow and white spots, longitudinal lines, microcracks, spots, thick skin;
  • nail plate changes its structure, becomes lumpy, thin, loose and brittle.

The second phase

In the second stage, the fungi begin to actively divide and the symptoms of an unpleasant disease begin to flourish literally before our eyes. The nail thickens and darkens, deforms, becomes brittle, over time, deep cracks appear in it.

The third phase

third stage nail polish

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

When the fungus has done its job and the diluted nail plate is rejected by the body as a source of infection, the fungus will spread to the nail bed. This is fraught with a purulent process and susceptibility to various infections.

Photo of onychomycosis in different variants of the course of the disease

Dermatologists identify different variants of the course of the disease. A foot look is enough for a specialist to make a diagnosis.

Normotrophic flow variant

Has the following features:

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

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

Hypertrophic course

Has the following symptoms:

  • deformation of the nail plate is visible to the naked eye;
  • the nail is collapsing;
  • plate color is gray, dirty yellow, brown, lack of natural luster;
  • hyperkeratosis, manifested by increased growth of horny cells of the upper plate, which causes discomfort while walking, painful sensation.

Most often, it is hyperkeratosis that is the main reason to seek medical attention.

atrophic variant of disease course

Atrophic variant of the course

Characterized by the following features:

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

In this case, the treatment is very difficult, the hopes for the restoration of the nail plate are minimal and the risk of the nail becoming completely atrophied is high.

Photo of pathogen-dependent nail fungus

There are three types of fungi that infect nail plate.


They can be recognized by the following symptoms:

  • deformation of the nail plate;
  • appearance of lines, stains, darkening of the nail;
  • malnutrition of nails and fungal damage is manifested by the appearance of brown and black spots;
  • redness and inflammation of the nail skin.
Yeast fungus

You have the following features:

  • the nail has become thinner and cheaper;
  • the periungal area is often inflamed;
  • lesion of the interdigital folds and legs.

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


Change in the following characteristic symptoms:

moldy appearance of nail fungus
  • change the color of the plate to green, black, gray;
  • fungus can develop after finger stroke;
  • mold does not penetrate deep into the nail.

Photo of onychomycosis depending on the form of the disease

The onset of negative manifestations in various cases starts from a certain place on the nail plate.

Distal variant

Its attributes:

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

Side variant

Has the following symptoms:

  • starts from the sides of the nail in the fold of the skin;
  • Fungal colonies, moving from side to side, 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 fungi from the beginning of the nail to the edge, which leads to the appearance of stains, thinning of the plaque.

Surface white

Has the following clinical picture:

  • can appear on any part of the nail plate;
  • rapid development and distribution;
  • due to the defeat of the top layer, the nail appears to be covered with white powder;
  • without obesity.

Total change

Symptoms of this nail fungus:

total variant of nail fungus
  • wide spread of infection from the free edge of the nail and cuticle;
  • inflammation of the periungal fold;
  • plate thinning or hyperticking;
  • fragility
  • .

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

The fight against nail fungus should start knowing that. Thanks to this selection of photographs, you can independently determine the causative agent, localization and severity of onychomycosis.
