Trichophytosis axillary

Introduction to echinococcosis Trichomycosis axillaries is also known as trichonocardiasisaxillaris, trichomycosis nodosa, and the pathogen is corynebacterium tenuis. The bacteria mainly invade the bristles and pubic hair, and are parasitic in the cells and cells of the dermis, which generally do not invade the skin. It is mainly popular in tropical and subtropical regions, and it is also distributed in temperate zones. basic knowledge The proportion of illness: 0.04% Susceptible people: no specific population Mode of transmission: contact sexual transmission Complications: cellulitis, folliculitis, foot swelling

The cause of echinococcosis

(1) Causes of the disease

The pathogen, corynebacterium tenuis, invades the pubic hair and pubic hair, and invades the cells and cells between the hairskin.

(two) pathogenesis

Corynebacterium tenuis, which mainly invades the pubic hair and pubic hair, is parasitic in the cells of the hairskin and between the cells, and generally does not invade the skin.

Trichophytonosis prevention

1. Pay attention to personal hygiene, develop a good bath, wash your hands and feet, and change the good hygiene habits of underwear and shoes.

2. Keep your skin dry.

3. Avoid contact with sputum patients and clothing, do not touch and play with rickets.

Complications of echinococcosis Complications, cellulitis, folliculitis, foot swelling

There are few complications of Trichophyton rubrum, such as not paying attention to hygiene, often scratching, and in rare cases can cause bacterial infection in deep tissues. Localized cellulitis, folliculitis, purulent sputum, subcutaneous tissue abscess, lymph node abscess, Majocchii granuloma, foot edema, verrucous hyperplasia, etc. Causes acute inflammation of local skin tissue such as redness, heat and pain, leading to symptoms such as fever and chills. It is necessary to pay attention to active anti-inflammatory treatment.

Symptoms of echinococcosis common symptoms inflammatory sputum hairy hair with tiny nodules itch licking hair thinning nodules

The sweaty person is prone to this disease, which occurs mostly in the mane hair. The pubic hair can also be invaded. The hair in other parts is not easily invaded. There are sparse scattered tiny nodules on the hair shaft. The nature is hard, the adhesion is firm, and sometimes it can be sheathed. Hair shaft, nodules are generally yellow, sometimes red or black (China is more common in yellow), obvious when sweating in summer, dry in winter is not easy to find, the hair is tarnished, pathogens such as invading the hair surface, can make hair shaft Damaged, the hair is easy to break, the nodular color can make the local sweat and clothes color, the skin is generally unchanged, and the patient has no symptoms.

Examination of echinococcosis

Histopathological examination: It can be identified as Corynebacterium parvum, and the short microscopic bacteria can be seen in the gelatinous substance of the nodule.

Diagnosis and identification of echinococcosis

diagnosis

Diagnosis can be made based on medical history, clinical manifestations, and examination.

Differential diagnosis

Pay attention to the identification of the following diseases

Folliculitis: Pseudo-smear Gram staining can be used to detect pathogenic microorganisms, and stubborn cases require bacterial culture and drug susceptibility testing. Histopathology is acute pustular inflammation in the hair follicle area, and lymphocytes, plasma cells, and histiocytic cells may infiltrate in chronic cases.

Peripheral keratosis: hereditary skin disease, rash is more common in the thigh and the upper arm, the infraorbital and perineal parts are rare, generally no symptoms, histopathology shows hyperkeratosis of the epidermis, hair follicle mouth expansion, embedded with horny plug.
