mouth floor and the second one on the left side of buccal mucosa with different clinical characteristics. The lesion in the mouth floor shows as an extensive ulcer of indefinite limits of granular to necrotic, whereas the lesion in the buccal mucosa presents as a white exophytic ulcer with a verrucous appearance. Both lesions presented exophytic with verrucous aspect, mixed coloration, and indefinite limits. After the incisional biopsy of both areas, histopathology examination identified the lesions as SCC. The patient was referred for treatment at the oral oncology center.

The transient lingual papillitis (TLP) initially reported in 1996 by Whitaker et al. is an inflammatory enlargement of fungiform papillae characterized by an abrupt onset with 2- to 3-mm masses developing over 1 hour, accompanied by moderate to severe pain, with or without pus. We present a case of TLP in an 8-year-old boy whose major complain was an acute burning sensation on the tongue that initiated almost immediately after contact after he ate a cucumber, accompanied by a severe salty taste perception. We observed multiple erythematous papules all over the dorsum of the tongue. Even without any therapeutic measure, his mother reported that 12 hours later, almost all the signs and symptoms had disappeared; TLP it is very common, and, although it presents a benign pattern of evolution, it is poorly known by doctors, who should be aware of this condition to diagnose and guide the patients properly.
REGIONAL ODONTODYSPLASIA IMAGING ASPECTS. TAMARA FERNANDES DE CASTRO, SAYGO TOMO, CARLA RENATA EDER SANOMYA IKUTA, DANIEL GALERA BERNABE, RICARDO BIASOLI, LEDA MARIA PESCININI SALZEDAS and, GLAUCO ISSAMU MIYAHARA Regional odontodysplasia (RO) is a rare developmental dental anomaly with a prevalence of less than 1 in 1,000,000 in humans. The main objective of the present work is to present imaging aspects of RO. A 13-year-old female patient was referred to the radiology clinic for panoramic radiography and cone beam computed tomography. In these examinations all the teeth in the left maxilla and the tooth 11 showed alteration in size and shape of the crown and root. The affected teeth had the appearance of "ghost teeth," with a reduction in enamel thickness and density in addition to large pulp chambers and open apices. Usually, the teeth presented developmental delay and eruption in relation to the corresponding ones on the contralateral side. The alterations identified in the imaging tests suggest a diagnosis of RO. The proposed treatment was conservative until the period of bone maturation.
ORAL MANIFESTATIONS OF KOSTMANN SYNDROME: CASE REPORT. RAQUEL RICHELIEU LIMA DE ANDRADE PONTES, ANA CAROLINE PENCHINA DE SOUZA, JULIANA SOARES PEREIRA, RENATO LIESS KREBS, WAGNER PEREIRA COUTINHO FILHO and, NANCY DE ASSIS FERREIRA
Kostmann syndrome (KS), or severe congenital neutropenia, is a rare autosomal recessive genetic disorder with a mutation in the HAX1 gene, located on chromosome 1 q21.3. The typical symptoms are abscesses located on various parts of the body: ear, cutis, lung, and oral cavity. The decrease in the number of neutrophils alters the host defense capacity, causing periodontal disease to manifest at an early age, with gingival inflammation, aggressive periodontal destruction, edema, periodontal pouches, and tooth mobility. The aim of this report is to describe the most typical signs of this pathology in the oral cavity presenting the case of a 15-year-old adolescent girl diagnosed as having congenital neutropenia with generalized early-onset periodontitis aggravated by this systemic condition and recurrent oral infections, generalized bleeding, and early dental loss.
JUVENILE TRABECULAR OSSIFYING FIBROMA: CASE REPORT OF AN AGGRES SIVE FIBRO-OSSEOUS LESION. TULIO BARROS DE OLIVEIRA, MORANDIN FERRISSE, ANALU LUCAS RIBEIRO TEIXEIRA, LUCIANA YAMAMOTO ALMEIDA, ANDREIA BUFALINO, VALFRIDO ANTONIO PEREIRA-FILHO and, JORGE ESQUICHE LEON Juvenile ossifying fibroma (JOF) is a benign bone-producing fibrous neoplasm of the skeleton. Clinically, children and adolescents are affected without preference for sex. There are 2 clinicopathologic variants, psammomatoid and trabecular (JTOF). JOF can be aggressive, suggesting a malignant neoplasm. A 26-yearold male patient with volumetric increasing of the mandible with a history of evolution of 2 months was referred for evaluation. Intraoral examination showed expansion of both bone cortical of the right mandibular body. Imaginological examinations evidenced a large osteolytic lesion with diffuse and nonsclerotic borders involving the right mandibular angle and body. Diagnostic hypotheses were ameloblastoma, fibrous dysplasia, central giant cell lesion, and JOF. Incisional biopsy was performed, which easily released lesional tissue. Microscopy showed fibrous stroma admixed with varying degrees of immature and mature osseous trabeculae. Final diagnosis was JTOF. The current case shows that strict clinicopathologic correlation is essential to differentiate JTOF from other bone-forming lesions.
STURGE-WEBER ANGIOMATOSIS: A CASE REPORT. MARINA FERNANDES BINIMELIZ, DANIEL FALHEIRO, BRUNO TURELI, RICART GIL MACEDO, LUCIENE SILVEIRA and, CESAR W. NOCE Sturge-Weber angiomatosis is a rare nonhereditary developmental condition, characterized by hamartomatous vascular proliferation involving the tissues of the brain and face. Its diagnosis can be established by the identification of the following criteria: port-wine stains, leptomeningeal angiomas, skull imaging with presence of gyriform calcifications in "tram lines," and intraoral involvement resulting in hypervascular changes. The purpose of this study is to perform a case report of Sturge-Weber angiomatosis, attended at a stomatology service. The male patient had port-wine tumoration on the left side of the face. Intraoral examination revealed hypervascular changes in the ipsilateral mucosa, including a large soft expansion of the hard palate. Skull imaging studies revealed gyriform calcifications in "tram lines." The diagnosis was a SturgeWeber angiomatosis. The dentist should be aware of the oral
