Nasopalatine Duct Cyst: A Case Report
OOOO Volume 120, Number 2 squamous epithelium with “keratin pearls” and pleomorphic, hyperchromatic cells. Based on the histopathology, the diagnosis was squamous cell carcinoma. The treatment was partial glossectomy and bilateral radical neck dissection, followed by radiotherapy.
PCC-216 - WARTY DYSKERATOMA OF THE ORAL CAVITY. JEANNE DA CUNHA MACEDO, LIANA BASTOS, ALINE CORREA ABRAHÃO, MÁRCIA GRILLO CABRAL, MICHELLE AGOSTINI, MÁRIO JOSÉ ROMAÑACH GONZALEZ SOBRINHO. UNIVERSIDADE FEDERAL DO RIO DE JANEIRO. Warty dyskeratoma or focal acantholytic dyskeratosis is an uncommon cutaneous lesion of pilosebaceous origin that affects the oral cavity only in rare cases, in which it presents mainly as a verrucous plaque in the alveolar ridge or hard palate of adult patients. The etiology of oral warty dyskeratoma remains unknown, and fewer than 50 cases have been described to date. A 40-year-old female presented with a well-defined, depressed whitish plaque on the lower posterior alveolar ridge. The lesion was asymptomatic, with a rough surface, and was 1 cm in diameter. An excisional biopsy was performed, and microscopic examination revealed a proliferative squamous cell epithelium with suprabasal split, containing dyskeratotic cells and basaloid cords proliferating into the submucosa. The final diagnosis was warty dyskeratoma. No recurrence was observed after 12 months of follow-up. Oral pathologists should be able to recognize this rare entity.
PCC-217 - NASOPALATINE DUCT CYST: A CASE REPORT.

UNIVERSIDADE FEDERAL DO AMAZONAS. Nasopalatine duct cyst (NDC) is the most common nonodontogenic cyst of the jaws. Its growth is slow and asymptomatic, and its pathogenesis is uncertain. This study reports a case of NDC in a 71-year-old male who was diagnosed during routine treatment at a school of dentistry. Extraoral and intraoral examination showed no abnormalities. Radiographic examination revealed a well-defined radiolucency, measuring approximately 1.5 cm, between the maxillary central incisors roots. The lesion was surgically removed by enucleation with the hypothesis of a cystic lesion. The histopathological examination showed a cavity surrounded by 3 types of epithelium (stratified squamous epithelium, cuboidal epithelium, and pseudostratified epithelium), thus confirming the diagnosis of NDC. At 3 years of follow-up, there was a sclerotic border remaining in the regenerated bone but there had been no recurrence.

ABSTRACTS Abstracts e67 Amelogenesis imperfecta represents a group of genetic disorders that affect the structure and clinical appearance of enamel on all or almost all of the teeth, negatively affecting oral health and quality of life, as well as causing physiological problems. This study reports 2 cases of amelogenesis imperfecta in patients within the same family: an 11-year-old brown-skinned male and his 16-year-old brown-skinned uncle. Both patients presented with a complaint of yellow discoloration of their teeth. Their medical and family histories were unremarkable. Intraoral examination showed that the height of the crowns of upper and lower posterior teeth was reduced, and that there were remarkable alterations in the enamel surface of some teeth. Panoramic radiography revealed the presence of a thin layer of enamel with a radiodensity higher than that of dentin. On the basis of the clinical and radiographic features, the final diagnosis was hypoplastic amelogenesis imperfecta in both cases.
PCC-219 - INVOLVEMENT OF MULTIPLE ORAL LESIONS IN AN APPARENTLY SYNDROMIC PATIENT: A CASE REPORT.

UNIVERSIDADE FEDERAL DO CEARÁ. In the maxillo-mandibular complex, lesions of various etiopathogeneses can occur. Although such lesions are typically solitary, in rare cases, multiple lesions with distinct natures occur. To date, there have been no reports of simultaneous involvement of periapical cyst, dentigerous cyst, and cementoblastoma in the same patient. A 38-year-old patient with a syndromic appearance (being of short stature and brachyfacial, as well as showing hypertelorism, although without a definitive medical diagnosis) presented with multiple oral lesions in the jaws. Intraoral examination revealed a residual periapical cyst, accompanied by a swelling in the anterior region of the maxilla, simultaneous to a dentigerous cyst and a cementoblastoma associated with tooth #35. Although simultaneous involvement of multiple lesions of different etiopathogeneses is uncommon in the literature, this report emphasizes the importance of thorough and systematic clinical examination, promoting the proper management and appropriate treatment of maxillary lesions.
PCC-220 - ORAL LYMPHOEPITHELIAL CYST WITH UNUSUAL CLINICAL PRESENTATION: A CASE REPORT.

UNIVERSIDADE FEDERAL DE CAMPINA GRANDE. Oral lymphoepithelial cyst is a rare lesion, the clinical aspects of which include an asymptomatic yellowish nodule (< 10 mm) with a regular surface and soft consistency. Most cases occur in regions of the oral cavity that harbor lymphoid aggregates, such as the floor of the mouth and the lateral and ventral surfaces of the tongue. Histologically, oral lymphoepithelial cysts exhibit a cystic cavity lined with a parakeratinized stratified squamous epithelium. The aim of this study was to report a case of oral lymphoepithelial cyst on the lateral surface of the tongue in a 36-year-old female. Intraoral examination revealed a sessile mass with the same color
