Objective To analyze the frequency of oral lesions and their characteristics in patients seen in the residency program at Santa Casa de Pelotas, Rio Grande do Sul, Brazil. Methods Reports of biopsies performed in the residency program at Santa Casa de Pelotas, during a period of three years, obtained from the Archives of the Center for Diagnosis of Diseases of the Mouth. From these, data were collected and analyzed with respect to histological diagnosis of the lesion, gender, age, ethnicity, lesion location, type of biopsy, and agreement between clinical and histopathology diagnosis. Results A total of 221 reports were analyzed, from which 55 different diagnoses were observed. Inflammatory fibrous hyperplasia was the lesion most commonly found, appearing in 38 reports (17%), followed by squamous cell carcinoma and mucocele in 17 reports, and radicular cyst in 15 reports. The main demographic characteristics shown were: Females in 59.09% of cases; the fifth decade of life in 29%, and caucasian ethnicity representing 85% of cases. As regards location, the lesions were concentrated mainly in the maxillary and mandibular soft tissues (29%). The number of excisional biopsies was higher, representing 91.4%. Agreement between clinical and histopathologic diagnosis was slightly higher (111 reports) than disagreements. Conclusion The results of this study were similar to those of the majority of the articles reviewed with regard to the most frequent oral lesions and their characteristics, in spite of the shortcomings found in the way requisition forms for histopathological examinations had been filled out.
