reported. All patients were over age 40 years and underwent excisional biopsy. Two lesions were diagnosed as BCA and the others as CA. Literature review of the MEDLINE, LILACS, and SCIELO databases used the key words basal cell adenoma,canalicular adenoma,and monomorphic adenoma.The site of occurrence of the BCA in the two cases reported was relatively uncommon. The clinical and histopathological features of the lesions were somewhat consistent with literature ndings. AO-06 - BILATERAL EAGLE SYNDROME: CASE REPORT. IGOR BRASIL VILLAR, BARBAHRA CAROLYNIE AMORIM REIS, DANIEL DO CARMO CARVALHO, DIMITRE RAMOS GRANDEZ ARAÚJO, IGOR BRASIL VILLAR, LUCIANO HENRIQUE DE JESUS, RICARDO FARIAS BRITO. FACULDADE CATHEDRAL. The bilateral eagle syndrome is characterized by an elonga- tion of the styloid process or mineralization of the ligamentous complex. Its manifestation is usually bilateral, and symptoms may or may not be present. Symptoms include facial pain of the un- derlying nerves and arteries close to the styloid process. Eagle syndrome is more common in adults and may be related to trauma or tonsillectomy. A patient reported difculty moving the neck and facial pains on swallowing. Radiographic examination with or without radiopaque contrast, medium showed bilateral miner- alization of the ligamentous complex of the mylohyoid. The proposed treatment was surgery via extraoral access. AO-07 - CASE OF PERIPHERAL AMELOBLASTOMA IN A MIDDLE-AGED MALE.

UNIVERSIDADE DE SÃO PAULO. Ameloblastoma is one of the most frequent odontogenic neoplasms but has an uncommon peripheral counterpart. Cauca- sian man, 56, was referred for evaluation of a left mandibular gingival lesion present for 10 months. Physical examination revealed an asymptomatic solid brous swelling, 1 cm in diam- eter, on the buccal aspect of the lower left alveolar ridge. The lesion surface was smooth and normal in color. Intraoral radio- graphs showed no abnormalities. A clinical hypothesis suggested peripheral osseous broma, prompting an excisional biopsy. One week later the lesion regained its initial proportions. Histological sections exhibited islands of ameloblastic epithelium in a follic- ular pattern in the lamina propria, central squamous metaplasia with keratinization, and some dystrophic calcication, leading to a nal diagnosis of peripheral ameloblastoma. The patient was referred to surgery for further evaluation and treatment. Peripheral ameloblastoma occurs in less than 2% of all ameloblastoma cases, affecting mainly the posterior mandible in the second and third decades of life.

ANA LUISA HOMEM DE CARVALHO, LAURA CAMPOS HILDEBRAND, MANOELA DOMINGUES MARTINS, MARCO ANTONIO TREVIZANI MARTINS, VINÍCIUS COELHO CARRARD, MARIA CRISTINA MUNERATO. UFRGS/HCPA. Cheilitis granulomatosa (CG) is a condition of unknown etiology clinically characterized as enlargement of the lips with the microscopic appearance of a nonspecic granulomatous inammation. White man, 33, had swelling of the lips and facial asymmetry of 6 yearsduration. Intraoral examination found a painless enlargement of the lower and middle upper lip. Lesions resembling cobblestones were also noted on the buccal mucosa bilaterally. Colonoscopy and hypersensitivity testing ruled out the diagnoses of Crohn disease and allergy, respectively. An inci- sional biopsy was performed in the lower lip. Microscopic assessment revealed noncaseating granulomatous inammation, leading to a diagnosis of CG. Intralesional corticosteroids (triamcinolone 10 mg/mL) were administered, and the patients condition is being closely followed. AO-09 - DELAYED ADVERSE EFFECTS RELATED TO HYALURONIC ACID DERMAL FILLER (RESTYLANE): CLINICAL FINDINGS AND TREATMENT OF ORAL MANIFESTATION. MARCOS MARTINS CURI, DANIEL HENRIQUE KOGA, CRISTINA ZARDETTO, CAMILA LOPES CARDOSO, SÉRGIO ROCHA ARAÚJO. HOSPI- TAL SANTA CATARINA, SÃO PAULO. Skin llers are often used in facial cosmetic surgery. Although they are considered safe, adverse reactions may occur but are rarely reported in the literature. Woman, 65, developed oral lesions related to hyaluronic acid 12 years after receiving skin llers. She complained of right buccal facial swelling after recent oral surgery. Palpation revealed notable rmness over the area that was diffuse, with no denitive outline. During follow- up, the patient developed two new painful nodules on the left facial side. She revealed that she had had soft-tissue augmentation in the past, conrming her previous aesthetic procedure. Samples obtained through incisional biopsy were evaluated histologically, revealing granulomatous allergic reactions associated with the use of hyaluronic acid. Treatment with local intralesional cortico- therapy resulted in remission after 3 months. This is a rare case of delayed adverse effect related to the use of the skin ller Restylane.

UNIMONTES/UNICAMP. Bartters syndrome (BS) is a renal tubulopathy that leads to polyuria, polydipsia, water and electrolyte imbalance, and neph- rocalcinosis. Amelogenesis imperfecta (AI) has been described in association with nephrocalcinosis. Eight patients with BS were screened for dental abnormalities. Decayed teeth in patients with suggestive clinical features of AI were analyzed by scanning electron microscopy. Typical features of AI were detected in two girls with BS who demonstrated nephrocalcinosis. The diagnosis and achievement of adequate clinical control were delayed. Ge- netic analysis detected the mutation responsible for BS in one girl, specically, a homozygous mutation of exon 5 of the KCNJ1 gene that resulted in a substitution of valine for alanine at codon 214 (A214V). The presence of AI in BS may indicate abnor- malities of the biomineralization process in tubular disorders can affect calcium deposition in dental tissues. Apoio: FAPEMIG e CAPES.

Ameloblastoma is one of the most frequent odontogenicneoplasms but has an uncommon peripheral counterpart. Cauca-sian man, 56, was referred for evaluation of a left mandibulargingival lesion present for 10 months. Physical examinationrevealed an asymptomatic solid fibrous swelling, 1 cm in diam-eter, on the buccal aspect of the lower left alveolar ridge. Thelesion surface was smooth and normal in color. Intraoral radio-graphs showed no abnormalities. A clinical hypothesis suggestedperipheral osseous fibroma, prompting an excisional biopsy. Oneweek later the lesion regained its initial proportions. Histologicalsections exhibited islands of ameloblastic epithelium in a follic-ular pattern in the lamina propria, central squamous metaplasiawith keratinization, and some dystrophic calcification, leading toa final diagnosis of peripheral ameloblastoma. The patient wasreferred to surgery for further evaluation and treatment. Peripheralameloblastoma occurs in less than 2% of all ameloblastoma cases,affecting mainly the posterior mandible in the second and thirddecades of life.
