Scrofuloderma of the chest with mediastinal TB.

Cutaneous tuberculosis is a rare manifestation of extrapulmonary tuberculosis caused by Mycobacterium tuberculosis in most cases and rarely by Mycobacterium bovis. Diagnosis may be challenging due to a wide range of clinical findings and similarities to other chronic dermatoses, leading to delayed treatment. We present a case of scrofuloderma in a 4-year-old girl that arose from a contiguous spread from the anterior mediastinum with associated pulmonary involvement.
