Ryl-Paltaufa Warty Tuberculosis of the Skin

Riel-Paltauf Warty Skin Tuberculosis is an infectious disease caused by Mycobacterium tuberculosis, manifested by the formation of superficial and deep-lying ulcers, blisters and tubercles on the skin with a conical or hemispherical outgrowth. The disease has been known since ancient times. It was first described in the works of Galen, Vesalius, Puer-Quen, Aristotle and others. Much attention was paid to the study of the pathogenesis of this disease by the pathologist Charrette in 1722. There is also a view of Riel-paltauf as a type of skin tuberculoma.

**Rila-paltauf verrucous** is a form of skin tuberculosis characterized by a rash of vesicular papules in the area of ​​the corners of the mouth and, more often, the back of the hands. The rashes are usually large, often multiple, dotted with subvesicular pustules, the surrounding skin is thickened and covered with hyperpigmented vegetations, and there are symptoms of lymphadenopathy. When examining biopsy material in Riehl-Patertauf, focal lymphohistiocytic infiltration is detected, and therefore this variant of tuberculosis has long attracted the attention of researchers. Microbial interruptions of Koch's bacillus in tissue have been described.
