[Tuberculous ulcer of the palate. Apropos of a case].

We present a case of orificial tuberculosis in a male of 51, consisting on an ulcer in the pallatum. This diagnosis lead us into finding an advanced active pulmonary tuberculosis which the patient ignored. We want also to emphasize the importance of a correct differential diagnosis regarding oral cavity ulcers, among which we must always keep in mind that tuberculosis is still quite common in our environment, as well as squamous cell carcinoma, reticulum cell sarcoma, eosinophilic granuloma, stomatitis ulceromembranous.
