UNUSUAL OCCURRENCE OF CLEAR CELLS IN ODONTOGENIC FIBROMA: A CASE STUDY WITH IMMUNOHISTOCHEMICAL ANALYSIS. PATRICIA GUERRA PEIXE GONCALVES, ¸ RODRIGO PORPINO MAFRA, HELLEN BANDEIRA DE PONTES SANTOS, LARISSA SANTOS AMARAL ROLIM, PATRICIA DARVIN GOMES PARENTE, LELIA BATISTA e DE SOUZA and, LEAO PEREIRA PINTO Odontogenic fibroma (OF) is an uncommon benign neoplasm with varying histopathologic features. We report a case of a 44-year-old female patient presenting a painful lesion in the maxilla with 8 months of evolution. Intraoral inspection showed a sessile, firm swelling measuring about 2 cm in diameter. Panoramic radiograph evidenced a well-defined radiolucency between teeth 16 and 18. Incisional biopsy was performed. Histopathologic analysis revealed a benign neoplasm characterized by proliferation of stellate ectomesenchymal cells associated with intense collagen deposition. Numerous islands and cords of odontogenic epithelium with a predominance of clear cells were evidenced. Epithelial cells showed immunopositivity for CK19, AE1/AE3, and Ki-67 but no immunopositivity for a smooth muscle actin, S-100, or CD68. Histopathologic diagnosis was OF, and the patient was referred for tumor excision. This is a case of particular interest because of the unusual occurrence of clear cells in the epithelial component of OF, which may lead to diagnostic difficulties.
TUBERCULOSIS OF THE ORAL CAVITY: CASE REPORT. AMANDA SILVA DE ALMEIDA LIMA, THIAGO MOREIRA PESSOA, GERALDO OLIVEIRA SILVA JUNIOR, MARILIA HEFFER ^ PIRES CANTISANO and, FABIO RAMOA Tuberculosis is a serious public health problem that, despite its decreasing incidence rate, still presents high mortality. It is a bacterial infection transmitted through the air, caused by the Mycobacterium tuberculosis bacterium that affects the lungs, and can remain latent or evolve to the disease state, spreading later to other parts of the body. This study exemplifies the case of a 57-year-old white man, a bookseller, smoker, and resident in an area without basic sanitation, who had white plaques mixed with erythematous areas in oropharynx with a 5-month evolution, difficulty in swallowing, and episodes of night fever. Histopathologically, a granulomatous inflammatory process was observed showing areas of necrosis and pseudoepitheliomatous hyperplasia. The periodic acid Schiff and Grocott stains were negative, and the Ziehl-Nielsen staining showed Epstein-Barr presence. The patient was referred for treatment.

A 58-year-old woman was referred because of a swelling in the anterior mandible associated with displacement of teeth and discomfort in the area. Medical history showed hypertension. Clinical examination revealed a 2.0-cm bluish swelling in the alveolar mucosa of the anterior mandible with hard consistency. Panoramic and periapical radiographs revealed a 3.0-cm well-defined unilocular radiolucent lesion in the anterior mandible. Vitality tests showed that some teeth associated with the lesion presented normal results, while others showed negative responses. Clinical diagnoses were glandular odontogenic cyst and ameloblastoma, and an incisional biopsy was performed. Histologic diagnosis was compatible with unicystic ameloblastoma, and the patient was submitted to a conservative surgical removal of the lesion. Final diagnosis confirmed unicystic ameloblastoma, and the patient is under clinical and radiologic follow-up. Histologic analysis showed different relationships of the tumor with the roots of adjacent teeth.
OROFACIAL FOREIGN BODY REACTION TO COSMETIC MATERIAL: REPORT OF 3 NEW CASES. NATALIA MELCOP, EMANUEL ^ A ROZA, ALINE MENDES, ANA LUIZA OLIVEIRA CORRE e ^ A ABRAHAO, CORRE MICHELLE AGOSTINI, BRUNO AUGUSTO BENEVENUTO DE ANDRADE and, MARIO e JOSE ROMANACH Orofacial foreign body reactions are adverse effects to cosmetic fillers that are often used for esthetic purpose. Case 1 involved a 76-year-old woman with a painless swelling in the upper lip lasting 1 year. Case 2 involved a 53-year-old woman presenting multiple painless normal-colored nodules of unknown duration located in the lower lip mucosa. Case 3 involved a 77year-old woman with a painless nodule in the right buccal mucosa of unknown duration. All patients admitted having undergone a cosmetic procedure in the past. Microscopically, all cases showed variable-sized empty microcysts, surrounded by a mixture of histiocytes, collagen bundles, multinucleated giant cells, and inflammatory cells. Patients are under follow-up after treatment that consisted of surgical excision of the material. Foreign body reactions to cosmetic fillers are uncommon in the orofacial region.
MULTIPLE HEMANGIOMAS WITH FORMATION OF PHLEBOLITH: CASE REPORT. GILBERTO MARCUCCI, VINICIUS PIOLI e ZANETIM, LEONARDO BRAUN GALVAO MAXIMO DIAS and, MARCELO MARCUCCI Lesions of vascular nature often suffer dystrophic calcification inside, called phleboliths, and are represented by radiopaque areas sometimes forming concentric circles. A white 30-year-old male patient complained of "purple growths in mouth and face for several years." Medical records were not contributory. During physical examination, we found purplish growths with discoloration in the labial mucosa and cutaneous region. During intraoral examination, we observed lesions on the lip mucosa, purplish in the commissures, and purplish nodules on the floor of the mouth and lingual side. Purplish stains are observed in retromolar trigone and lingual dorsum regions. With a diagnosis of hemangiomas, occlusal x-ray was performed, which revealed radiopacities (phleboliths) in the mouth floor corresponding to the vascular lesions of the region. We referred him for a systemic evaluation by a vascular surgeon. Phleboliths can be easily confused with sialoliths, therefore requiring careful consideration by the clinician.
