analysis were performed. The histologic slices revealed the presence of ectopic serous salivary glands located in the head of the left condyle, characterizing a Stafne defect. Faced with this diagnosis, the conduct was the patients periodic follow-up.
KILLIAN POLYP IN THE MAXILLARY SINUS: A CASE REPORT. ANDERSON IDELFONSO BATISTA FERNANDES, MOYARA MENDONCA ¸ LIMA DE FARIAS, RENATA GUALBERTO e VASCONCELOS, DA CUNHA, WANESSA GUIMARAES FLAVIO LIMA DO AMARAL SILVA, TATIANA NAYARA ^ LIBORIO-KIMURA and, JECONIAS CAMARA The antrochoanal polyp, also called Killian polyp, represents around 4% to 6% of all nasal polyps with a higher incidence in children and young adults. It is a benign lesion that grows from the mucosa of the maxillary sinus and reaches the choana. A 34year-old male patient attended the surgical service to remove a mesiodens. No noteworthy changes were observed at the intraoral examination. Computed tomography evidenced a well-circumscribed and delimited hypodense mass in the left maxillary sinus. An excisional biopsy was performed, and histopathologic analysis revealed the presence of a loose, edematous connective tissue with thin lines consisting of collagen fibers, congested vessels, and a discrete presence of lymphocytes and plasma cells. Another region exhibited a peduncle composed of connective tissue and the presence of ciliated pseudocolumnar epithelium. The diagnosis of a Killian polyp was established. The patient is under follow-up for 4 months without signs of relapse.
PERIPHERAL CALCIFYING ODONTOGENIC CYST: DIAGNOSTIC CHALLENGE. PAULA LIMA FREITAS, LETICIA ALMEIDA OLIVEIRA, GABRIEL OLIVEIRA CRUZ, JHEINIS STEFANY PASCUINELI DUARTE, KARIBE CARLI FRANK, JOSE e JUNIOR NARCISO ROSA ASSUNC ¸ AO and, VICTOR PEREZ TEIXEIRA A 62-year-old male patient with light brown skin color sought the stomatology clinic with complaint of cyst in the inferior alveolar ridge for 2 months without symptoms. Extraoral examination showed no alterations. Intraoral examination presented nodular sessile lesion with delimited boundary and the same color of the adjacent mucosa that measured approximately 10 mm in the left inferior alveolar ridge, on canine tooth area, without trauma history association. Periapical radiography was requested that evidenced a cup-shaped resorption area. With a diagnostic hypotheses of peripheral giant cell lesion and peripheral ossifying fibroma, an excisional biopsy was performed, and treatment of the bone resorption was started. The anatomopathologic analysis showed a fragment of cystic lesion coated by stratified squamous epithelium with arch projections, ghost cells, and amorphous lobular mass, confirming the diagnosis of peripheral calcifying odontogenic cyst. The patient remains on clinic and image control during 8 months without signs of recurrence.
COMBINED NEVI (BLUE AND INTRAMU COSAL) ON ORAL MUCOSA. RUBIA DA ROCHA VIEIRA, KARINE RASERA and, PAULA LUCE BOHRER Combined nevi are composed of 2 or more distinct populations of nevus cells. In the oral cavity it is usually blue nevi combined
OOOO January 2020 with common intramucosal nevi. In the blue nevus component, the dendritic cells can reach very deep into the mucosa, even reaching the periosteum. An 8-year-old female patient underwent an examination in March 2018 with a dark brown lesion located on the right upper maxillary gingiva without pain. However, the mother reported an increase in size during the last months. An excisional biopsy was performed and the material sent for anatomopathologic examination. The histologic slice featured a combination of 2 distinct forms of nevus. At the top, near the epithelium is mostly intradermal nevus. At the bottom, there is a blue nevus composed of elongated, dendritic, and heavily pigmented melanocytes accompanied by melanophages. Morphologic findings were consistent with combined nevi (blue and intramucosal).

EDUARDO LIBERATO DA SILVA, VINICIUS COELHO CARRARD, FERNANDA VISIOLI, NATALIA BATISTA DAROIT, TATIANA WANNMACHER LEPPER, ISADORA LUANA FLORES and, LAURA DE CAMPOS HILDEBRAND An 85-year-old retired white man sought the dentistry service with an ulcerated lesion without symptomatology in the attached gingiva between upper molars. The ulcer presented approximately 1 £ 1 cm surrounded by a white plaque. He has hypertension, hypercholesterolemia, hypothyroidism, and prostate alteration and regularly uses metoprolol, amlodipine, simvastatin, levothyroxine sodium, and finasteride. Hematologic, laboratory, and radiographic examinations are within the normal range. The patient uses upper and lower partial dentures and denied smoking or drinking habits. However, he reported the habit of brushing the area with force. Histopathologic diagnosis suggested eosinophilic ulcer. Even after instruction of atraumatic hygiene, antifungal treatment, application of topical corticosteroids, and sublesional infiltration and photodynamic therapy, there was no regression of the lesion. Over time, the ulcer increased in size and migrated to the buccal mucosa and labial commissure. This case remains without a conclusive diagnosis, and new analyses are being made.
GREEN TEETH DUE TO INTENSIVE CARE OF NEONATAL COMPLICATIONS - A CASE REPORT.

The condition may affect patients with severe liver dysfunction associated with increased levels of bilirubin. A 21-month-old female patient was referred for evaluation of severe green discoloration of all her primary teeth. Her medical history revealed premature birth at 31 weeks of gestation in addition to an episode of early sepsis and neonatal jaundice. The girl developed necrotizing enterocolitis and underwent 2 laparotomies followed by a new episode of sepsis. After that, the patient presented acute renal failure, fungal infection, and bronchopulmonary dysplasia. Because of all these complications and the high drug levels all within 3 months, the girl developed drug-induced hepatitis, resulting in hyperbilirubinemia. The management of the case involved appointments for
