Primary oral tuberculosis in an immunocompetent patient

Primary tuberculosis of the tongue is very rare. The chronic ulceration is commonly misdiagnosed as a cancerous lesion. We report the case of a 44 years old immunocompetent woman who presented with a lingual chronic painful ulceration. The biopsy of the lesion showed a granulomatous inflammation, with caseous necrosis in the center. The ulceration healed after a 6 month tuberculosis treatment.
