reported. All patients were over age 40 years and underwentexcisional biopsy. Two lesions were diagnosed as BCA and theothers as CA. Literature review of the MEDLINE, LILACS, andSCIELO databases used the key words “basal cell adenoma,”“canalicular adenoma,” and “monomorphic adenoma.” The site ofoccurrence of the BCA in the two cases reported was relativelyuncommon. The clinical and histopathological features of thelesions were somewhat consistent with literature findings.
AO-06 - BILATERAL EAGLE SYNDROME: CASE REPORT.IGOR BRASIL VILLAR, BARBAHRA CAROLYNIEAMORIM REIS, DANIEL DO CARMO CARVALHO,DIMITRE RAMOS GRANDEZ ARAÚJO, IGOR BRASILVILLAR, LUCIANO HENRIQUE DE JESUS, RICARDOFARIAS BRITO. FACULDADE CATHEDRAL.
The bilateral eagle syndrome is characterized by an elonga-tion of the styloid process or mineralization of the ligamentouscomplex. Its manifestation is usually bilateral, and symptoms mayor may not be present. Symptoms include facial pain of the un-derlying nerves and arteries close to the styloid process. Eaglesyndrome is more common in adults and may be related to traumaor tonsillectomy. A patient reported difficulty moving the neckand facial pains on swallowing. Radiographic examination withor without radiopaque contrast, medium showed bilateral miner-alization of the ligamentous complex of the mylohyoid. Theproposed treatment was surgery via extraoral access.
AO-07 - CASE OF PERIPHERAL AMELOBLASTOMA IN AMIDDLE-AGED MALE. BIANCA FREO, NELISEALEXANDRE DA SILVA LASCANE, THIAGO SALVADORDE LIMA YAMADA, DÉCIO DOS SANTOS PINTO-JÚNIOR, MARINA HELENA CURY GALLOTTINI,NORBERTO NOBUO SUGAYA, FÁBIO ABREU ALVES.UNIVERSIDADE DE SÃO PAULO.
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.
AO-08 - CHEILITIS GRANULOMATOSA: CASE REPORT.ANA LUISA HOMEM DE CARVALHO, LAURA CAMPOSHILDEBRAND, MANOELA DOMINGUES MARTINS,MARCO ANTONIO TREVIZANI MARTINS, VINÍCIUSCOELHO CARRARD, MARIA CRISTINA MUNERATO.UFRGS/HCPA.
Cheilitis granulomatosa (CG) is a condition of unknownetiology clinically characterized as enlargement of the lips withthe microscopic appearance of a nonspecific granulomatous
inflammation. White man, 33, had swelling of the lips and facialasymmetry of 6 years’ duration. Intraoral examination found apainless enlargement of the lower and middle upper lip. Lesionsresembling cobblestones were also noted on the buccal mucosabilaterally. Colonoscopy and hypersensitivity testing ruled out thediagnoses of Crohn disease and allergy, respectively. An inci-sional biopsy was performed in the lower lip. Microscopicassessment revealed noncaseating granulomatous inflammation,leading to a diagnosis of CG. Intralesional corticosteroids(triamcinolone 10 mg/mL) were administered, and the patient’scondition is being closely followed.
AO-09 - DELAYED ADVERSE EFFECTS RELATED TOHYALURONIC ACID DERMAL FILLER (RESTYLANE):CLINICAL FINDINGS AND TREATMENT OF ORALMANIFESTATION. MARCOS MARTINS CURI, DANIELHENRIQUE KOGA, CRISTINA ZARDETTO, CAMILALOPES CARDOSO, SÉRGIO ROCHA ARAÚJO. HOSPI-TAL SANTA CATARINA, SÃO PAULO.
Skin fillers are often used in facial cosmetic surgery.Although they are considered safe, adverse reactions may occurbut are rarely reported in the literature. Woman, 65, developedoral lesions related to hyaluronic acid 12 years after receivingskin fillers. She complained of right buccal facial swelling afterrecent oral surgery. Palpation revealed notable firmness over thearea that was diffuse, with no definitive outline. During follow-up, the patient developed two new painful nodules on the leftfacial side. She revealed that she had had soft-tissue augmentationin the past, confirming her previous aesthetic procedure. Samplesobtained through incisional biopsy were evaluated histologically,revealing granulomatous allergic reactions associated with the useof hyaluronic acid. Treatment with local intralesional cortico-therapy resulted in remission after 3 months. This is a rare caseof delayed adverse effect related to the use of the skin fillerRestylane.
AO-10 - DENTAL MANIFESTATIONS IN TWO PATIENTSWITHBARTTER’S SYNDROME. SIBELE NASCIMENTO DEAQUINO, SHIRLENE PIMENTEL FERREIRA, ANA CRISTINASIMÕES E SILVA, DÉBORA MARQUES MIRANDA, PAULACRISTINA PEREIRA, RICARDO DELLA COLETTA,HERCÍLIO MARTELLI-JÚNIOR. UNIMONTES/UNICAMP.
Bartter’s syndrome (BS) is a renal tubulopathy that leads topolyuria, polydipsia, water and electrolyte imbalance, and neph-rocalcinosis. Amelogenesis imperfecta (AI) has been described inassociation with nephrocalcinosis. Eight patients with BS werescreened for dental abnormalities. Decayed teeth in patients withsuggestive clinical features of AI were analyzed by scanningelectron microscopy. Typical features of AI were detected in twogirls with BS who demonstrated nephrocalcinosis. The diagnosisand achievement of adequate clinical control were delayed. Ge-netic analysis detected the mutation responsible for BS in onegirl, specifically, a homozygous mutation of exon 5 of the KCNJ1gene that resulted in a substitution of valine for alanine at codon214 (A214V). The presence of AI in BS may indicate abnor-malities of the biomineralization process in tubular disorders canaffect calcium deposition in dental tissues. Apoio: FAPEMIG eCAPES.
