Tuberculosis verrucosa cutis (TVC) is a form of cutaneous tuberculosis that results from accidental inoculation of Mycobacterium tuberculosis in a previously infected or sensitized individual with a moderate to high degree of slowly evolving cell-mediated immunity.
It is also known as "prosector's wart".
The most frequent site for the wart are the hands. But it can occur anywhere in the skin, such as in the sole of the feet, in the anus, and, in the case of children from developing countries, in the buttocks and knees.
The diagnosis is confirmed by a skin biopsy and a positive culture for acid-fast bacilli. A PPD test may also result positive.
Therapy for cutaneous tuberculosis is the same as for systemic tuberculosis i.e 4-drug regimen, i.e., isoniazid, rifampin, pyrazinamide, and ethambutol or streptomycin.
