leukoplakia, confirmed by histopathology, which indicated intense epithelial dysplasia. The patient was referred for surgical treatment. The patient in this case was not exposed to oral cancer risk factors. Therefore, it reinforced the need of a detailed intraoral examination to detect early potentially malignant lesions.
A CASE REPORT OF OSTEOSARCOMA IN THE MANDIBLE. ANA MARIA DIAS DA ^ NIO RODRIGUES, RODRIGO COSTA, EUGE RESENDE, LUISA AGUIRRE BUEXM, FERNANDO DIAS, ADRIANA TEREZINHA NEVES NOVELLINO and, SIMONE DE QUEIROZ CHAVES LOURENCO ¸ The report describes a case of mandibular osteosarcoma in a 25-year-old black male patient complaining of increase of volume in mandible with evolution of 4 months. The anamnesis stated a previous history of mucoepidermoid carcinoma in the left retroauricular region treated by parotidectomy 18 years ago. Physical examination revealed the swelling of the left body of the mandible with face asymmetry and an expansive increase of volume in the buccal region of the mandible, extending to vestibule depth, associated with pain on palpation and paresthesia. Panoramic radiograph revealed a poorly defined radiolucent image without sclerotic border, with destruction of the periodontal ligament corresponding to tooth 36. Incisional biopsy was performed, and the histopathologic report was compatible with osteosarcoma. The patient was referred for oncology treatment. Osteosarcomas in the mandible are extremely rare, and this case justifies investigation as the patient had already presented another type of tumor in the proximal region.
EXTENSIVE SIALOLIPOMA IN THE MOUTH FLOOR OF AN 11-YEAR-OLD CHILD: A CASE REPORT. ERASMO BERNARDO MARINHO, EALBER CARVALHO MACEDO LUNA, FABRICIO BITU SOUSA, KARUZA MARIA ALVES PEREIRA, EVELINE TURATTI and, ROBERTA BARROSO CAVALCANTE An 11-year-old boy was referred to our department complaining of painless swelling in the neck and floor of the mouth with an evolution time of approximately 2 months. Extraoral examination revealed a soft tumefaction on the right side of the sublingual region with normal surface color. Intraoral examination revealed a soft tumefaction on the anterior right side of the floor of mouth with normal surface color. Panoramic radiograph and complete blood count ruled out infection of odontogenic origin. Negative aspiration puncture ruled out cystic lesions. Salivary gland tumor was considered as diagnostic hypothesis. Incisional biopsy under local anesthesia was planned. However, surgical procedure was favorable, and the lesion was completely removed. Histologic sections showed mature adipocytes septated by delicate bundles of collagen fibers and interspersed by islands of salivary parenchyma, obtaining a histopathologic conclusion of sialolipoma. No evidence of recurrence was observed after 19-month follow-up.

OOOO January 2020 CAPOBIANGO SOARES DE MOURA, LUISA AGUIRRE BUEXM and, ALESSANDRA OLIVEIRA FERRANI GOMES Ranula is a common lesion of the mouth floor, resulting from rupture of the salivary gland duct and extravasation of mucin, usually associated with local trauma. Higher prevalence among young people and children is observed. Treatment options include marsupialization, excision of the gland involved, and micromarsupialization, the less invasive technique. A 28-year-old lactating female patient without previous oral lesions was complaining of "lump in the mouth." Intraoral examination showed a bluish-floating increase of volume in the right mouth floor crossing midline, associated with ulcer near the occlusion line, with clinical diagnosis of ranula. Micromarsupialization was the treatment of choice, and after 8 months, there was complete regression of the lesion without recurrence. This technique is a good treatment option because of its simplicity of execution and low invasiveness, being prioritized in patients like the one from this case report.
EXUBERANT CEMENTO-OSSIFYING FIBROMA OF THE MAXILLA. BERNARDO CORREIA LIMA, SABRINA MORELLI, MARIA APARECIDA CAVALCANTE, BRUNO AUGUSTO ^A BENEVENUTO DE ANDRADE, ALINE CORRE ABRAHAO, MICHELLE AGOSTINI and, MARIO e ROMANACH Cemento-ossifying fibroma (COF) is a benign fibro-osseous neoplasm that commonly presents as a slow-growing, welldefined mixed radiolucent-radiopaque lesion, located in the posterior mandible of women in their third and fourth decades of life. A 59-year-old male patient was referred complaining of an asymptomatic 8 £ 7 cm swelling of progressive growing in the last 5 years located in the posterior region of the maxilla. Panoramic radiograph showed a well-defined, predominantly radiopaque lesion with marked cortical bone expansion and maxillary sinus involvement. Microscopic evaluation showed proliferation of cellular fibroblastic stroma containing mineralized trabeculae of varying size and occasional concentric calcifications. There was no continuity between the tumor and surrounding normal cortical bone. The final diagnosis was COF. The patient was submitted to conservative surgery, and no recurrence was observed after 6 months of follow-up. COF of the maxilla may present as a painless and well-defined fibro-osseous tumor of large size.

In the physical examination, the mucous membranes remained intact. When palpating, we noticed bone crepitation in the maxilla and mandible bones. The panoramic x-rays showed welldefined radiolucent images without any radiopaque halos extending from the right mandibular ramus to the molar region on the left.
