CLINICAL CASE: A 42 year-old male, smoker, was referred for evaluation of an ulcer located in the gingiva, during one month, that produced disturbances. On the intraoral examination we appreciated an ulceration of 0,5 cm, on a mandibular torus, in the lingual gingiva of the left first molar (Fig. 1-2). A panoramic x-Ray (Fig.3), a CT scan (Fig. 4) and a biopsy were taken (Fig. 5-6. Fig. 6 is a S-100 stain).
