PE-316 - TISSUE NECROSIS IN HIV-POSITIVE PATIENTTAKING CHEMOTHERAPY FOR ACUTE LYMPHO-BLASTIC LEUKEMIA SUBTYPE 3: DENTAL APPROACH.CAROLINE ZIMMERMANN, LILIANE JANETE GRANDO,JOANITA ANGELA GONZAGA DEL MORAL, AIRA MARIABONFIM SANTOS, LUCIANA GOULART MEDEIROS,CÍNTIA LOCKS, MARIA INÊS MEURER.

Acute lymphoblastic leukemia (ALL) subtype 3 (Burkitt’sleukemia) is an aggressive cancer of B cells. It may be associatedwith human immunodeficiency virus (HIV) infection, and itstreatment can induce stomatotoxicity. Man, 33, with ALL subtype3 and HIV infection started chemotherapy and antiretroviraltreatment and developed grade II oral mucositis and necroticulcer in the mucosa that progressed to bone necrosis (anteriormandibular region, teeth #32 to #42). The dental measuresadopted included antibiotic therapy based on culture of thenecrotic bone, photodynamic therapy with low-power laser (red),mouthwash with chamomile iced tea during drug infusions, strictoral hygiene care, and subsequent bone surgery. The patientexperienced some hospital stays, discharges, and readmissions,and ultimately passed away. Patients with ALL require highlycomplex treatment and a multidisciplinary approach. Hospitaldental monitoring is essential to improve the patient’s qualityof life through the use of preventive, curative, and palliativeapproaches.

Oral lichen planus is a chronic inflammatory disease ofautoimmune character and unknown origin. Erosive lichen planuscan cause painful symptoms and manifest as atrophic erythema-tous areas with ulceration. Woman, 65, complained of burningmouth. Her medical history revealed hypertension and daily useof losartan. Intraoral and histopathological examination resultswere compatible with erosive oral lichen planus. Initial treatmentwith topical steroids (dexamethasone elixir) for 4 weeks produceda slight improvement. The drug was replaced by clobetasol pro-pionate (0.05%) plus nystatin, which led to a significant reductionof lesions and pain in the first week. Therapy was continued formore 3 weeks, until the disappearance of pain and most of thelesions. The patient is being followed up. Despite clobetasolbeing a potent topical corticosteroid and the first-line treatmentfor oral lichen planus, total remission of lesions does not alwaysoccur.

PE-318 - TRANSIENT LINGUAL PAPILLITIS RELATEDTO FOOD ALLERGY. ANNA PAULA NIGRI, ALINEARAÚJO SILVA, NATHÁLIA ALMEIDA, SARAHAPARECIDA ANTERO, MARIA ELIZA BARBOSA RAMOS,ROSEMIRO DE MENEZES MACIEL, MÔNICA ISRAEL.UERJ.

Transient lingual papillitis (TLP) is an inflammatory condi-tion that has an uncertain pathogenesis and has been associatedwith several different factors. It affects the fungiform papillae ofthe tongue and is most common in women. White man, 30,described a burning sensation and pain on the lateral portion ofthe tongue’s dorsum present for about a week. The physical ex-amination revealed focally localized erythematous and hyper-trophied papillae. After a meticulous history was obtained, anassociation between food hypersensitivity and the patient’sclinical features was noticed. Because TLP has no precisepathogenesis, the history assumes a vital role in correlatingsymptoms and causation and is indispensable to reaching thecorrect diagnosis.

PE-319 - TRAUMATIC DENTOALVEOLAR INJURYWITH TOOTH IMPACTION MIMICKING MIXEDODONTOGENIC LESION: CASE REPORT.

Man, 84, came to the stomatology service with a fistula in theleft submental region present for 6 months. He reported sponta-neous purulent drainage. Intraoral examination showed mild boneirregularity in the region of the lower alveolar ridge. The patientstated that at age 13 years he suffered a mule kick that causedchin trauma with multiple fractures and loss of teeth. Panoramicradiography indicated a mixed image with well-defined edges andcentral calcified spots surrounded by a radiolucent area measuringabout 2.0 � 1.5 cm. Possible diagnoses included various odon-togenic lesions. Based on the clinical and radiographic charac-teristics, surgical exploration was performed and the lesion wasexcised. Several tooth fragments were removed, consistent withthe history of traumatic dentoalveolar injury. Histopathologicalanalysis showed chronic suppurative inflammation. After surgery,the extraoral fistula resolved completely. The patient continuesto attend clinical and radiographic follow-up with no signs ofrecurrence.

PE-320 - TRAUMATIC NEUROMA: REPORT OF TWOCASES. MARCOS ANTONIO NUNES COSTA SILAMI,DANIELLE RESENDE CAMISASCA, MARCIA DUARTESOTHER, REBECA DE SOUZA AZEVEDO, SILVIAPAULA DE OLIVEIRA. ODONTOCLÍNICA CENTRAL DOEXÉRCITO (OCEX).

Traumatic neuroma is a reactive lesion of neural origin thatdevelops in a nerve bundle after trauma. In the repair process,axon growth occurs to reestablish neural connections, butsometimes a mass resembling an ordinary reactive lesion de-velops at the site of injury. Two cases of traumatic neuroma arereported. Woman, 61, had a white lesion associated with amandibular removable partial denture clip in the alveolar mu-cosa corresponding to the inferior left canine. It was sensitive totouch. Man, 67, revealed multiple normochromic papules in theapical tongue present for 1 year. Sensitivity associated withsmoking and drinking was present. In both cases, excisionalbiopsy was performed and the final diagnosis was traumaticneuroma. No recurrences developed. The reported traumaticneuromas are common and show consistent symptoms, althoughthe clinical presentation differs from the typical nodular patterndescribed.
