ATYPICAL BILATERAL EXOSTOSIS IN MAXILLA—CASE REPORT
OOOO Volume 129, Number 1 ulcerations related to cytomegalovirus (CMV) are uncommon and rarely described in patients with solid tumors. A 65-year-old male patient under oncologic treatment because of a high-grade astrocytoma was admitted to our service complaining of pain on the right lateral border of the tongue with 5 weeks of evolution, without clinical improvement with topical corticosteroid use. Physical examination revealed an oval ulcerated lesion approximately 0.5 cm in diameter with necrotic center. An excisional biopsy was performed, and results showed areas of superficial ulceration, a chorion with lymphoplasmacytic inflammatory infiltrate, and presence of occasional endothelial and stromal cells with massive cytoplasm and nuclear inclusions with cytopathic effect by cytomegalovirus, confirmed by immunohistochemistry. The lesion completed healed after 15 days, and no further treatment was necessary.
DIAGNOSTIC CHALLENGES OF ORAL LESIONS IN A PATIENT AFTER HEMATOPOIETIC STEM CELL TRANSPLANTATION. WANESSA MIRANDA-SILVA, CLAUDIA JOFFILY PARAHYBA, RAFAEL SARLO VILELA, YANA AUGUSTA NOVIS, FELIPE PAIVA FONSECA and, EDUARDO RODRIGUES FREGNANI Oncohematologic patients after hematopoietic stem cell transplantation (HSCT) are at risk of developing opportunistic oral infections and malignant neoplasms. The objective of this report is to describe 3 diagnostic challenges of oral lesions that affected the same posttransplant patient: an atypical herpes simplex virus lesion in ventral tongue, a gingival actinomycosis infection, and later a leukemic infiltration on the soft palate. A 57-year-old female patient first complained of a progressive and painful sublingual nodule for 3 days at D+35 of HSCT by extranodal natural killer/T-cell lymphoma, and final diagnoses were atypical herpes simplex virus 1 and 2 infection. Two months later, ulcerated lesions in the vestibular and palatal gingival margin of the left upper molars were noted, with final diagnosis of Actinomyces sp infection. Fifteen days later, an erythematous lesion with necrotic center was observed in the soft palate, and the diagnosis was palatal infiltration by extranodal natural killer/ T-cell lymphoma.
SURGICAL TREATMENT OF INFLAMMATORY DENTIGEROUS CYST ASSOCIATED WITH THIRD MOLAR IN MANDIBLE: CASE REPORT. RAFAEL SARAIVA TORRES, SAULO LOBO CHATEAUBRIAND DO NASCIMENTO, RENATA GUALBERTO DA CUNHA, PAULO MATHEUS HONDA TAVARES, JOEL MOTTA JUNIOR, VALBER BARBOSA MARTINS and, MARCELO VINICIUS DE OLIVEIRA Most dentigerous cysts are considered developmental, but some cases can present an inflammatory pathogenesis. We report a case of enucleation of a large inflammatory dentigerous cyst in a 20-year-old patient with tooth extraction involved. The patient presented to dental care to evaluate the noneruption of third molars. No significant changes were observed in the extraoral examination. The intraoral examination showed the growth of the vestibule region of tooth 48, and discrete bulging of the lingual cortical was observed. Computed tomography showed an extensive hypodense unilocular image associated with the crown of tooth 48. The lesion was enucleated together with element 48.

The histologic examination concluded as an inflammatory dentigerous cyst. After 1 year and 6 months of follow-up, no recurrence was observed, and the patient had a great prognosis.
MUCOEPIDERMOID CARCINOMA ON THE HARD PALATE: A RARE CASE REPORT. CRISLYNE MENDES DA VERA CRUZ, LUIZA MADALENA MENDES DA VERA CRUZ, LEONARDO DE SOUZA LOUZARDO, ALEXANDRA GABRIELLY DE SOUSA BENTES, JOYCE HELENA MONTEIRO BARBOSA, BIANCA PANTOJA CAMPOS and, ANA LUIZA SARMENTO DOS SANTOS Mucoepidermoid carcinoma (MEC) is a malignant salivary gland neoplasm most commonly found in the oral cavity, occurring mainly in the major salivary glands. The most used treatments for MEC include local surgery alone or surgery associated with radiotherapy with or without cervical emptying. The objective of this study was to report the case of 18-year-old L.C.M., who had a lesion on the left side of the hard palate, with an evolution period of 5 years and characteristics very representative of MEC. An incisional biopsy was performed in the lesion region to confirm the diagnosis. After confirmation, the patient was referred for removal of the lesion and radiotherapy treatment. Five years after the surgery and radiotherapy treatment, the patient is well and without signs of relapse. It is concluded that the faster the diagnosis and treatment, the greater the chances of the patient being cured.
ATYPICAL BILATERAL EXOSTOSIS IN MAXILLA—CASE REPORT. CARLOS HENRIQUE COSTA BAPTISTA DE MELLO, JOSE ALEXANDRE DA ROCHA CURVELO, GUSTAVO DE SOUZA VIEIRA, CLARA GOMES CALDEIRA BARBOSA, MARIANA CAMPELLO NUNES, KELLY TAMBASCO BEZERRA and, MARIA ELISA RANGEL JANINI Patient M.C.J., a 34-year-old woman, was referred to the oral diagnostic service complaining of a bilateral bone protrusion extending through the vestibular surface of the alveolar bone of maxilla. She reported discomfort after meals due to food accumulation provided by the plateau formed in the region. At physical examination, the hypothesis of exostosis was raised, which was confirmed by computed tomography. Upon receiving the diagnosis, the patient was informed that the most appropriate course would be preservation of her condition. Exostoses are bone excrescences located on the vestibular surface of the alveolar bone. They are rarely a source of pain or discomfort, and their treatment is not necessary except for prosthetic considerations or in cases of recurrent trauma to the mucosa of the region.
