To submit data on the histopathological diagnosis made in the Oral Pathology Department of Stomatology of Autonomous University in Nuevo León, Monterrey, Mexico during from 1989 to 2008. From 2 183 biopsies, bone tissue lesions accounted for 637 cases (29.2 %) and those that soft tissue summarized 1 529 (70 %), from dental tissue 17 samples (0.8 %) were processed. For bone tissue the more frequent diagnoses were: periapical granulomas, periapical cyst, dentigerous cyst and odontogenic keratocyst (keratogenic odontogenic tumor). The more frequent diagnoses for the soft tissue are: fibroma, pyogenic granulomas, mucocele, epidermoid carcinoma and papiloma. In maxillary there were 292 cases, in maxilla 258 and in 87 samples there was no specification from which maxillary was obtained the biopsy. In soft tissue, from gum 505 biopsies were obtained, from inferior lip 164, from soft tissue 157 were not specified, tongue 147, alveolar mucosa 146, hard palate 89 and other areas underwent 321 biopsies. From female patients 1 370 biopsies were obtained (62.8 %) and from male patients 796 biopsies (36.4 %). There was a coincidence of 1 482 cases (67.9 %) between the clinical diagnosis and the histopathological one, the no coincident ones summarized 172 (7.9 %) and 529 cases (24.2 %) where there wasn't clinical diagnosis being acceptable according to similar studies, but could be significantly improved by a continuous education.
