 Tuberculosis of the skin called a number of violations in which TB bacteria - those that usually cause pulmonary tuberculosis - affect the skin. TB skin - it's pretty rare variety of extrapulmonary tuberculosis Extrapulmonary tuberculosis - many forms  Extrapulmonary tuberculosis - many forms
 . Even in countries such as China and India, where TB incidence is very high, cutaneous tuberculosis is rare - less than the 0.1% of patients.

Mycobacteria can get into the skin of lungs (via lymph or blood), or through small lesions in the skin; in most cases tuberculosis Tuberculosis - a full recovery is not guaranteed  Tuberculosis - a full recovery is not guaranteed

Symptoms of TB of the skin

Usually, the first symptoms of tuberculosis Symptoms of TB - how to recognize the disease  Symptoms of TB - how to recognize the disease
   skin appear 2-4 weeks after mycobacterium penetrated into the skin. The manifestations of this disease is largely dependent on its type and the type and severity of tuberculosis, in turn - on the strength of the immune response and the virulence of mycobacteria.

Verrucose lupus is most common in adults, and in men. As a rule, the disease affects the skin on the back of the hand, fingers, feet, elbows, knees and buttocks. The first sign of warty tuberculosis is usually a convex skin tumors purple or brown-red. It increases gradually with time the skin may appear a few of these warty formations. Additionally, the affected skin can form abscesses. There are cases where these tumors persist for years, and then were on their own, without treatment. This, of course, does not mean that the disease can ride - on the contrary, in cases of suspected TB skin as soon as possible to seek medical help.

Lupus usually affects the skin around the mouth, in rarer cases - the neck, arms, legs, or torso. The skin produces small reddish-brown lumps with clear boundaries. Over time, these tumors can cause large scars and, sometimes, to skin cancer.

Strumoderma or skrofuloderma mostly develops in the skin in the neck or chest. Such lupus in children and young adults is more common than in middle-aged and elderly. Kollikvativny TB often develops in patients with tuberculosis of the lymph nodes Tuberculosis of the lymph nodes - the degree of complexity of the disease  Tuberculosis of the lymph nodes - the degree of complexity of the disease

Patients with very weak immune papulonekrotichesky tuberculosis may lead to the formation of deep ulcers of various areas of the skin. Low immunity in these patients may also lead to the fact that the Mantoux test will show a negative result, due to which the diagnosing lupus is difficult.


Diagnosis of tuberculosis of the skin

Mycobacterium Infections in patients with any form of TB is set by the tuberculin skin test, analysis of the secretion of interferon-gamma and / or sputum.

Treatment of tuberculosis of the skin

Patients who have been diagnosed as pulmonary and extrapulmonary tuberculosis, prescribe anti-TB drugs. Typically, the most effective is a combination of medicines, as isoniazid, rifampicin, pyrazinamide and ethambutol.
