Cutaneous tuberculosis is an extrapulmonary form of tuberculosis
characterized by distinct clinical and histopathological
presentations. Tuberculous chancre, a form of primary inoculation
tuberculosis, primarily affects individuals with no natural or
acquired immunity against the tubercle bacilli. It is commonly
acquired after minor trauma or any traumatic procedures. Initially,
it starts as a papule or nodule that gets ulcerated. The ulcer is
typically painless, has undermined bluish margins, is friable in
nature, and heals with atrophic scarring. If left untreated, it can
lead to various complications. The tuberculous chancre responds
well to antituberculous therapy. The emergence of resistant strains
and the AIDS epidemic led to a global resurgence of cutaneous
tuberculosis in the last century. Hence, awareness of the clinical
manifestations of cutaneous tuberculosis is necessary for its early
diagnosis and management. We report a case of tuberculous
chancre in a 45-year-old previously healthy male.
