OOOO Volume 129, Number 1 cells, which have abundant cytoplasm filled with eosinophilic granules that resemble lysosomes. A 37-year-old male patient was referred to a maxillofacial surgery clinic with swelling in the mandible noticed 10 years earlier. Two previous biopsy results were suggestive of ameloblastoma. Intraorally, there was a nodular swelling in the right alveolar ridge involving the region of premolars and molars, and computed tomography showed an expansible and multilocular lytic lesion. Histologic examination revealed a lesion composed of fibrous stroma with cell sheets presenting extensive granular cell transformation, surrounded by peripheral ameloblast-like cells. Immunohistochemistry showed negativity for Ki-67. The diagnosis was GCA. A marginal resection of the mandible was performed, and the microscopic examination confirmed the diagnosis. The patient remains in monitoring, and the reconstruction surgery of the mandible will be held soon.
ORAL MANIFESTATION OF CROHN DISEASE - A CASE REPORT. RUCHIELLI LOUREIRO BORGHETTI, LETICIA SPINELLI JACOBY, MARIA EDUARDA LANES BALDINO, JULIANE DE QUADROS DE BORTOLLI, KAREN CHERUBINI, MARIA ANTONIA ZANCANARO DE FIGUEIREDO and, FERNANDA GONCALVES ¸ SALUM A 29-year-old male patient was referred to a specialized service with gingival lesions that lasted 10 years. The medical history showed untreated Crohn disease. Intraoral examination detected firm nodules at the vestibular retromolar region of the right and left mandibular molar, red in color, recovered by ulcerated mucosa, and both measuring 2 cm. The buccal mucosa revealed a swollen, cobllestone appearance and showed deep linear ulcerations. Incisional biopsy was performed, and histopathologic analysis showed a connective tissue with intense chronic inflammatory infiltrate and neutrophils, blood vessel neoformation, and epithelioid cells. We recommended the use of 0.12% topical chlorhexidine. Because of persistent oral lesions, the patient was redirected to a gastroenterologist for further investigations and systemic treatment. Clinical control remains for 2 months. Approximately one-third of Crohn disease patients develop extraintestinal manifestations. Treatment of oral lesions included treatment of the intestinal disease and cooperation between gastroenterologists and specialists in oral medicine.
ERYTHEMA MULTIFORME. KAREN MARIA e GUIMARAES PACHECO, ALINE PEREIRA BERNARDINO, THIAGO CORDEIRO PIMENTEL MAFRA, CAROLINA PONTELO PIRES, e ARMOND and, FABIOLA DAVI DE NUNES, SEBASTIAO HERMINIA MARQUES CAPISTRANO A 58-year-old woman attended a clinic with “lumps in the hands and wounds on the mouth that appeared a year ago, that would come and go.” On the last recurrence, “blisters were formed.” She reported using antibiotics, antidepressants, antihypertensives, and analgesics. On extraoral examination, dark macules on the arms and hands were observed. On intraoral examination, ulcerated lesions and white plaques on the buccal mucosa were observed bilaterally. An incisional biopsy was performed, and the diagnosis was nonspecific inflammatory process. Then, a 1mL intramuscular injection of betamethasone dipropionate was prescribed. After 15 days lesions on the buccal mucosa recurred. The patient returned with new skin lesion erythematous in the
form of a target, which proved the diagnosis of erythema multiforme, and 1-mL intramuscular injections of betamethasone dipropionate were applied. The doctor discontinued the analgesics and antibiotics. After 6 months, the patient returned with no lesions but with scars.
AMELOBLASTIC FIBRODENTINOMA: CASE e DE ANDRADE, REPORT. IAN MAGALHAES EDUARDA GALLITO FERES, MIRIAM e BEATRIZ JORDAO MOREIRA SARRUF, RODRIGO FIGUEIREDO DE BRITO RESENDE, ADRIANA TEREZINHA NEVES NOVELLINO ALVES, SIMONE DE QUEIROZ CHAVES LOURENCO ¸ and, JOSIANE COSTA RODRIGUES DE SA A 10-year-old white male patient was referred to the clinic because of absence of tooth 37. Extraoral examination was irrelevant. Intraoral examination showed absence of tooth 37 and the left inferior retromolar region covered by normal mucosa with normal bone contour. Cone beam computed tomography revealed unilocular hypodense image with hyperdense margin and hyperdense foci inside, between the unerupted teeth 36 and 37, which was displaced. Diagnostic hypothesis was odontoma. Treatment consisted of lesion excision under local anesthesia, and tooth 37 has been maintained. The histopathologic report confirmed the final diagnosis of ameloblastic fibrodentinoma. The patient is under follow-up without relapse.
RECONSTRUCTION OF THE MIDDLE THIRD OF THE FACE WITH PARALLEL SEGMENTS WITH MICROVASCULAR FIBULAR FLAP: NEW TECHNIQUE. LAURINDO MOACIR SASSI, JOSE L DISSENHA, MARIA ISABELA GUEBUR, FERNANDO L ZANFERRARI, ALFREDO B SILVA, PAOLA A.G. PEDRUZZI and, GYL H.A. RAMOS Each reconstruction has its differences. Our objective was to show a different way. Study Design: A.R.F., an 18-year-old white man, presented a tumor with diagnosis of fibrous dysplasia in the maxillary bone (M), palate, and zygomatic complex (ZC) on the left side. After the maxillectomy with immediate reconstruction, we observed the anatomic flaw of the M caused by the tumor removal. When in power of the vascularized fibula, it was possible to cut, with osteotomy, in 4 segments, with each segment length depending on the size of the bone flaw. The first segment was used to reconstruct the orbit floor and ZC. The second one (3 cm) was discarded. The third one was used to reconstruct the M on the medium line to the third superior molar. Finally, the fourth segment formed an angle of 90 degrees with the third segment from the distal portion. Conclusion: This surgical technique presented a satisfactory result.
