She was described by the doctor back in 1866.Recognize this disease is very easy due to the presence on the hair of the colonies of the fungus in the form of a white clutch.

  • White whiskers;
  • White head piedra;
  • White pubic piedra;
  • White podrum axillary hollows;
  • White beard piedra.

Given the peculiarity of the inflammatory process, the disease is divided into 2 stages:

  1. Acute.
  2. Chronic.

The appearance of the white piedra can be judged from the following video:

Causes of

The cause of the disease in humans is the ingestion of Trichosporon beigelii fungus into the body. In addition to this fungus, the disease can be provoked by others from the genus Trichosporon:

  • Trichosporon giganteum;
  • Trichosporon ovale;
  • Trichosporon cerebriforme.

The disease is transmitted from the patient to the healthy. More often men are ill. The fungus is transmitted in such ways:

  • Through foreign hairbrushes;
  • Through other people's headgear;
  • lubrication of hair with oils, fermented milk products.

Spores of Trichosporon beigelii are located around the hair. Through the cuticle of the hair penetrates only a small part of the fungus.

Symptoms of

The commonly considered disease occurs in chronic form. The presence of the disease is indicated by the presence of small, dense nodules on the surface of the hair. These nodules are white in color, the shape of them may be oval or irregular. They cover the hair around. About 30 - 40 nodules can attach to one hair. The ring they form reaches a length of 10 mm.

Nodules covering hair are fungus spores. When the patient pulls his hair very tight, the nodules can stick together. This is how the tufts are formed, which is called the "columbian coil", they are like sheaves of cereals.

If a bug infested with a fungus is bent, a characteristic crunch will be heard that indicates a violation of the integrity of the Trichosporon beigelii colony. Fungus affects only the hair shaft. With this disease, the hair does not break, do not fall out. Only when the form is started can threaten alopecia areata.

If the patient has leukemia, he may develop a generalized infection. In addition, the body shows a hemorrhagic, papular rash. Over time, the rash passes into blisters containing hemorrhagic contents.


mycosis head If suspected to occur, develop a white piedra should seek help from such specialists:

  • mycologist;
  • trichologist.

To detect this infectious disease, it is necessary to pass such diagnostic tests:

  • General analysis of urine.
  • Delivery of blood for glucose.
  • Biochemical blood test.
  • General blood test.

In addition, biochemical research will be required:

  • Study of protein, its fractions.
  • Determination of the amount of total, direct bilirubin.
  • Determination of the level of transaminases( AST, creatinine, ALT, alkaline phosphatase, urea, thymol sample).

It is also recommended for the patient to undergo specific diagnostics:

  1. Cultural research, which involves the cultivation of a colony of this type of fungi on the Saburo nutrient medium.
  2. Study of hair, affected by a fungus, which is carried out by specialists under a microscope. Study of filament fungus, which has a size of only 4 - 6 microns.

Patients can carry out differential diagnosis. It is necessary to exclude the patient from such diseases as: pediculosis, false piedra.


White piedra refers to chronic diseases, so it is very difficult to cure it. The best option is full shaving of the hair, but most patients do not like this method of treatment.
