What is Warty Skin Tuberculosis?
Warty skin tuberculosis – this disease is more common in adults, and males are significantly more likely to get sick. In the bulk, the disease is associated with the nature of the profession and affects people working with tuberculosis material from the corpses of animals and people: veterinarians, butchers, slaughterhouse workers, pathologists, as well as medical personnel who have contact with patients who suffer from active forms of tuberculosis.
Pathogenesis during Warty Skin Tuberculosis
In these cases, warty tuberculosis of the skin develops as superinfection. In some patients who already have open tuberculosis of the lungs, intestines, bones, etc., this skin pathology is the result of self-infection.
Symptoms of Warty Skin Tuberculosis
Typical locations of the process are the rear of the hands and fingers, somewhat less often it is localized on the feet. First, a dense, bluish-red tubercle (cadaveric tubercle), which has a tendency to grow, is formed, which has a tendency to grow, eventually turning into a flat dense plaque. On the surface of the plaque formed large horny layers and wart growths. The mature focus of warty tuberculosis of the skin has three zones: a purple-red border (peripheral zone), a warty formation (middle zone), an atrophic area of skin with a tuberous bottom (central zone).
When cured on the spot lesions are formed scars. In the foci of warty tuberculosis subcutaneous microabscesses are formed with the release of pus droplets. Often there is involvement in the process of lymph nodes and blood vessels. New nodules and plaques may form around the main nidus, later merging with each other. Typically, changes in the general condition of patients does not occur, in most cases it remains quite satisfactory. 80-96.5% of patients have positive tuberculin reactions.
Diagnosis of Warty Skin Tuberculosis
It is based on clinical manifestations (purple-red rim along the periphery of the focus, three zones), typical location of the process, positive tuberculin samples. The disease should be differentiated from simple warts, vegetative pyoderma, blastomycosis, chromomycosis, sporotrichosis. Simple warts do not have inflammatory manifestations. Vegetative pyoderma is characterized by pronounced inflammation and abundant purulent discharge. Chronic mycoses are confirmed by histological studies and microscopy. Spinocellular carcinoma is asymmetric, located at the natural orifices and quickly decays with the formation of ulcers.
Treatment of Warty Skin Tuberculosis
Treatment is carried out with specific anti-tuberculosis drugs, X-ray irradiation, cauterization, curettage of the lesions with a sharp spoon are used.
The course of the disease is chronic and long enough, but most often it ends in complete recovery.
