We describe a tuberculin test (PPD) negative patient with a chronic cutaneous lesion with histological features resembling sarcoidosis, in whom M. tuberculosis complex DNA was detected in formalin-fixed paraffin-embedded tissue by polymerase chain reaction (PCR) amplification. The lesion cleared with antituberculous treatment.
