Background: - Cutaneous tuberculosis is an infection caused by M. tuberculosis complex, M.bovis and Bacillus Calmette-Guérin, which depending on individual immunity, environmental factors and type of inoculum may present varied clinical and evolutionary aspects(3). Cutaneous TB is one of the most elusive and more difficult diagnoses to make for dermatologists practicing in developing countries because of the difficulty in obtaining a microbiological confirmation(3).Cutaneous TB comprises only a small proportion (1%- 2%) of all cases of TBnevertheless, bearing in mind the high prevalence of TB in many developing countries, these numbers become significant (19) |
