Cutaneous tuberculosis (TB) is a rare form of extrapulmonary tuberculosis that can have diverse clinical manifestations. Cutaneous involvement may occur as a result of exogenous inoculation, contiguous dissemination from a focus of infection, or by hematogenous spread from a distant focus (1). Multibacillary forms of cutaneous localization remain by far the most common in children (2). Children and the elderly are greatly affected due to immunological inability to contain the mycobacterial infection. Scrofuloderma can occur in isolation or coexist with pulmonary and disseminated forms of TB. It presents with erythematous nodules that fistulize and discharge caseous and purulent material (3). Anatomopathological examinations reveal abscesses, necrosis and tuberculoid granulomas (3). Clinical, biological, pathological correlation and sometimes progression with antibacillary treatment are the key to diagnosis (2).
