Cutaneous tuberculosis of the pinna: an unusual location

Cutaneous tuberculosis (CT) is a relatively uncommon, presenting 1-1.5% of all extrapulmonary tuberculosis manifestations. The pinna location is exceptional. We reported the case of an immunocompetent, vaccinated 59 year-old man, who presented a chronic skin lesion of the left ear evolving for 2 years and wrongly treated with topical and oral antibiotics. In histopathological evaluation of the incisional biopsy from the lesion, she was found to have tuberculosis. The patient responded to 4-drug anti-tubercular treatment. CT should be mentioned as a differential diagnosis in all chronic skin lesions of the external ear especially in endemic countries.
