- Tuberculosis is an infection caused by a Mycobacterium called Mycobacterium Tuberculosis.
- It is a condition favoured by high population density, promiscuity (poverty, intravenous drug abusers, HIV) and the use of immunosuppressants (biologics, ciclosporine…). It is frequent in Sub-Saharan Africa, but new cases are a cause of concern, notably in China, Russia, South-East Asia and some countries in Africa which account for 80% of new cases.
- Although there are skin manifestations, it is a systemic disease which can have dire consequences on the lungs and other organs (especially in its miliary form).
- Treatment consists of a combination of antituberculous drugs, which must be continued for several months.
- Vaccination (Immunization) is also available: BCG vaccine (Bacille-Calmette-Guérin)
Skin manifestations are:
- Exogenous tuberculosis
- Primary inoculation tuberculosis
- Tuberculosis Verrucosa Cutis
- Endogenous Tuberculosis
- Orificial tuberculosis (Tuberculosis Cutis Orificialis)
- Hematogenous/lymphatic tuberculosis
- Lupus Vulgaris
- Acute Miliary tuberculosis
- Tuberculid (Mycobacterium absent from lesion)
- Erythema Induratum of Bazin
- Lichen Scrofulosorum
- Papulonecrotic Tuberculid
