PE-127 - AMELOBLASTIC FIBRO-ODONTOMA IN THEMAXILLA: HISTOLOGICAL CONSIDERATIONS ANDSURGICAL TREATMENT. RENNAN LUIZ OLIVEIRA DOSSANTOS, MARIA LUÍSA SOARES, LUCAS ALEXANDRE DEMORAIS SANTOS, PRISCILLA FLORES SILVA, ANTONIOFIGUEIREDO CAUBI, FÁBIO LUIZ NEVES GONÇALVES,RAFAEL DE QUEIROZ MOURA. FOPeUPE.

Ameloblastic fibro-odontoma (AFO) is a rare benign odon-togenic tumor that alters the formation of dentin and enamel.Patient, 18, underwent routine panoramic radiographs to evaluatethe absence of an upper right second molar that had not erupted.Ectopic inclusion associated with the lesion involved the entiretooth, producing areas of radiolucency and radiopacity. Excisionbiopsy of the lesion, followed by enucleation, sinusectomy, andexcision of the involved tooth were performed. Histopathologicalexamination revealed fragments of neoplasm of mixed odonto-genic source with connective tissue similar to dental papilla andislands of odontogenic epitheliumdfindings consistent with adiagnosis of ameloblastic fibro-odontoma. Six months intofollow-up there was persistence of the tissue inside the leftmaxillary sinus, suggestive of recurrence. A new biopsy wasperformed, which found fibrous connective tissue and mucosa ofthe maxillary sinus compatible with scarring.

Osseous dysplasias (ODs) are idiopathic processes restrictedto the gnathic bones and characterized by the substitution ofnormal bone by fibrous tissue and metaplastic bone. OD is clas-sified as focal, periapical, or florid. A case of florid OD wasdiagnosed after a failed tooth extraction. Black woman, 40,required evaluation of a swollen area in the posterior leftmandible found a year earlier after a tooth extraction in the area.Panoramic radiography revealed radiolucencies with radiopaquefoci extending from the molar area to the lateral incisor area.Suspecting a complex odontoma, an excisional biopsy was per-formed. Histopathological examination revealed fibrous tissue ofvarying cellularity interspersed with irregular bone trabeculae andsmall masses of cementum-like material, which exhibited a directconnection with a tooth root remnant. The definitive diagnosiswas florid OD. After 1 year of careful follow-up, the patient re-mains asymptomatic.

PE-129 - FLORID OSSEOUS DYSPLASIA ASSOCIATEDWITH OSTEOMYELITIS: CONSERVATIVE SURGICALMANAGEMENT. LETICIA FERNANDA HAAS, CAROLINEZIMMERMANN, LILIANE JANETE GRANDO, MARIA INÊSMEURER, VICTOR LOUSAN DO NASCIMENTO POUBEL,FILIPE MODOLO, FILIPE IVAN DANIEL. UNIVERSIDADEFEDERAL DE SANTA CATARINA.

Florid osseous dysplasia (FOD) is characterized by multi-focal fibro-osseous lesions in the jaws. Microscopically, normalbone is replaced by fibrous stroma containing cemento-osseoustissue. The affected areas tend to exhibit hypovascularization andnecrosis. Alveolar atrophy in edentulous jaws may expose thesemasses to the oral environment, resulting in infection and

osteomyelitis. Woman, 73, had dentures in place and was seekingcare for painful symptoms in the premolar region of the rightmaxilla. Granulation tissue was noted surrounding areas ofexposed bone. The patient reported previous facial cellulitis thatwas successfully treated with antibiotic therapy. Diagnostic im-aging revealed lesions consistent with FOD, with characteristicsof infection in the region of the clinical complaints. Antibiotictherapy was initiated, with plastic surgery of the affected regionand discontinuation of the use of dentures. The treatment waseffective, with healing by secondary intention. In FOD, rigorousclinicoradiographic correlation is essential, and conservativemanagement could be considered.

PE-130 - FOCAL EPITHELIAL HYPERPLASIA (FEH) IN AHUNGARIANMANLIVING INBRAZIL. CLÁUDIA MARIANAVARRO, CHAIENE EVELIN ZAGO, CLEVERTONROBERTO DE ANDRADE. FACULDADE DE ODONTOLO-GIA DE ARARAQUARAeUNESP.

Focal epithelial hyperplasia (FEH) is rare in people living inurban areas. Hungarian man, 43, who was living in Brazil cameto the oral medicine service complaining of “swellings on thelip.” Intraoral examination revealed several exophitic, sessile,smooth-surfaced nodules situated on the right and left of thelower lip mucosa. The asymptomatic lesions ranged in size from1 to 3 mm in diameter, were firm on palpation, and were coveredby normal pink mucosa that was not ulcerated or inflamed. Themedical history revealed no systemic disease. The patient deniedrisky sexual behavior related to human papillomavirus (HPV)infection. He reported no similar lesions in family members. Thedifferential diagnosis included condyloma acuminatum, oralflorid papillomatosis (in early stage of development), and FEH.Histological examination confirmed FEH. This case illustrates arare presentation of FEH usually found in Indian and Eskimochildren.

PE-131 - FOCAL OSTEOPOROTIC BONE MARROWDEFECTS: CASE REPORT. NATHALIA DE ALMEIDAFREIRE, TUANNY LIMA RANGEL, AMANDA DE SOUZASANT’ANNA, RAPHAELA CAPELLA, SARAH ANTERO,ROSEMIRO MACIEL, MÔNICA ISRAEL. UERJ.

The diagnosis of focal osteoporotic bone marrow defects isimportant because this variation show radiographic characteristicsthat could be misinterpreted as other lesions. Woman, 43, wasreferred to the FOUERJ Clinic of Oral Medicine by her dentistbased on radiographs taken before implants were placed. Twopanoramic radiographs, dated 2011 and 2012, both presented aradiolucent image that was multiloculated and located in the areafrom tooth #37 to tooth #44 that maintained the same size. Therewere no clinical manifestations, so it was concluded that theimage was caused by focal osteoporotic bone marrow defects.The patient was educated about the diagnosis and dischargedwithout surgical intervention.
