Tuberculosis cutis verrucosa A18.44

Rare, post-primary superficial paucibacillary inoculation tuberculosis due to exogenous reinfection or autologous superinfection after the tuberculous primary complex with partial immunity and normergic reaction of the organism. Infection occurs when handling material containing the pathogen.

Notice! Occupational disease of the skin (farmers, butchers, anatomists, pathologists).

Typical post-primary re-infection of the skin with good immunity. Penetration of tubercle bacteria into the skin through small injuries. Frequently occurring in people who work in agriculture.

Butcher's tubercle: mainly farmers, butchers, veterinarians. Mostly type bovinus; extremely chronic course.

Mild tuberculosis: Doctors, employees in pathological or anatomical institutes. Mostly type humanus, often acute course with tuberculous lymphangitis.

Mostly blurred, round, oval or polycyclic, indolent or slightly touch-sensitive, brown-red, coarse, coarse, sloppy papules or plaques, occasionally papulopustules or erosions with crustal formations. Lesions are often surrounded by an inflammatory halo. The lesions show peripheral progression and central scarring. Secondary infections and regional lymph node swelling are common.

Note: Since mycobacteria cannot penetrate intact skin, the manifestations of infection are typically found at the site of injury.
