Cutaneous tuberculosis is a rare form of tuberculosis infection that may lead to chronic lesions of skin and be missed in diagnosis due to location of the appearance of the lesions. This is a very rare case of peri-oral cutaneous tuberculosis in a 21-year-old man with no other specific sign of symptoms of tuberculosis infection but mimics signs of Herpesviridae family infection. The biopsy of the lesions and Ziehl-Neelsen stain revealed the diagnosis of cutaneous tuberculosis. By the beginning of the treatment of this unusual form of tuberculosis, the lesions had begun to fade and after 8 months, they were totally faded.
