MONOSTOTIC FIBROUS DYSPLASIA: CASE REPORT
ABSTRACTS
e72
complete blood count; prophylactic antibiotic prescription; medical release for extraction of teeth 85, 84, 74, 53, and 65; restorations; and prophylaxis. At the end of the procedures, the patient returned after 7 days for suture removal, with continuity only for routine examinations.
INTRAORAL MOLLUSCUM CONTAGIO SUM. CAMILA ZORASKI DE FREITAS, RUBIA DA ROCHA VIEIRA, MARIA ESTER KESLER and, PAULA LUCE BOHRER Molluscum contagiosum is a viral infectious disease that mainly affects children and young adults. The lesions occur predominantly in the skin and genitalia; involvement of the oral soft tissues is uncommon. Oral lesions occur most frequently on the lips, tongue, and buccal mucosa. A 20-year-old woman presented with pink, smooth, sessile, and painless papules on the upper lip with an evolution time of 2 weeks. The conduct was excisional biopsy of the lesion and histopathologic examination. The histologic slices revealed a well-defined epithelial proliferation, with areas of central depression, filled with keratinocytes altered by the virus. The final diagnosis was molluscum contagiosum. The patient consulted her gynecologist, who found lesions on the genitals.
MUCOEPIDERMOID CARCINOMA OF THE RETROMOLAR REGION: A CASE REPORT. CAROLINA MARIA CAMPOS, HELLEN BANDEIRA DE PONTES SANTOS, EVERTON DE FREITAS MORAIS, AFONSO NOBREGA DANTAS, RANI IANI COSTA GON¸CADO, HEBEL CAVALCANTI e and, ROSEANA DE ALMEIDA FREITAS GALVAO Mucoepidermoid carcinoma is the most common malignant tumor of the major and minor salivary glands. Some factors are reported to be involved in its development, including genetic disorders, exposure to ionizing radiation, and smoking. A 33-yearold woman presented with a painless swelling on the retromolar region that had evolved over a period of 3 years. The lesion was a 2-cm firm nodule covered with normal mucosa. Extraoral examination showed no lymph node alterations, and no radiographic changes were observed. An incisional biopsy was performed with the hypothesis of salivary gland tumor. Histopathologic analysis revealed a malignant salivary gland neoplasia characterized by the proliferation of epidermoid cells, mucous cells, and intermediate cells. Neoplastic cells were organized in solid sheets and formed ductal structures in a fibrous stroma. The final diagnosis was mucoepidermoid carcinoma. The patient was referred to the local referral surgery service for surgical procedure and is under follow-up.
PYOSTOMATITIS VEGETANS: CASE REPORT OF A RARE ORAL CONDITION. BRUNA DE OLIVEIRA, ALVARO DOS SANTOS GOES CAVALHEIRO SOARES, MARILIA HEFFER CANTISANO, GERALDO OLIVEIRA SILVA JUNIOR and, ELIANE PEDRA DIAS Pystomatitis vegetans is a rare oral condition characterized by the presence of numerous pustules in the oral cavity and is usually associated with inflammatory bowel diseases (IBD). A 19-year-old black male patient attended the stomatology service
OOOO January 2020 complaining of pruritus and pain in the oral cavity for 6 months. Physical examination revealed pustular lesions with erythematous halo and a friable membrane (“snail tracks”) located on the tongue, floor of the mouth, gingiva, labial mucosa, buccal mucosa, and hard and soft palates. He denied gastrointestinal symptoms. Scrapes of oral mucosa for cytopathologic analysis revealed intense inflammation and absence of Candida spp. An incisional biopsy of the lower lip was performed for histopathologic analysis, confirming the diagnosis. Therapy with oral prednisone 5 mg/d was instituted, with partial resolution, and the increase to 40 mg/d resulted in complete remission. Currently, he is being followed up by the stomatology service, since he has periods of relapse, and by gastroenterology, to detect possible IBD.
FOREIGN-BODY REACTION IN THE UPPER LIP: CASE REPORT. CAROLINA MARIA CAMPOS, DAUREA ADILIA COBE SENA, HELLEN BANDEIRA DE PONTES SANTOS, LEORIK PEREIRA DA SILVA, LAUDENICE DE LUCENA PEREIRA, e PEREIRA PINTO and, LELIA LEAO BATISTA DE SOUZA Foreign-body reaction is an inflammatory process caused by the presence of immunologically inert exogenous materials in the organism. A 47-year-old female patient, who was hairdresser, presented with an exophytic lesion in the upper lip, whose coloration was similar to that of the mucosa, which evolved over the course of 20 years. The patient reported no history of systemic diseases, submission to aesthetic procedures, or history of facial trauma. Thus, the clinical diagnosis was fibrous hyperplasia. After excisional biopsy, the histopathologic analysis revealed the presence of vacuoles and cells with clear cytoplasm compatible with macrophages in connective tissue. The immunohistochemical reaction for CD68 demonstrated strong diffuse immunoexpression in a large number of cells, confirming the presence of macrophages. The final diagnosis was foreign body type reaction. The patient is still under follow-up, and after 6 months there were no signs of recurrence.
MONOSTOTIC FIBROUS DYSPLASIA: CASE REPORT. BRUNA GALUPPO, DAVY MAIRON BRAGA PIAZZA, ADRIANA PARISOTTO MACEDO, ALBERTO FEDELI JUNIOR, ANDRE LUIZ DE OLIVEIRA and, DIOGO LENZI CAPELLA In fibrous dysplasia, abnormal proliferation of fibroblasts and differentiation of osteoblasts occurs, resulting in a defect of bone marrow replacement by a fibrous connective tissue. The case report refers to a 54-year-old patient with complaints of facial asymmetry who in the intraoral palpation presented painless, immotile swelling with normal bone consistency and mucosal staining. Radiograph revealed radiolucent unilocular lesion associated with diffuse radiopacities and poorly defined margins. The patient underwent surgery for excisional biopsy under general anesthesia. Surgical access was extraoral through submandibular incision and, for localization of the lesion, ostectomy was performed on the mandibular branch with piezo motor. After locating the lesion, curettage and removal of fibrous tissue associated with calcifications were performed. Despite the close proximity with the inferior alveolar nerve, the patient did not present hyperalgia or related paresthesia. The histopathologic report was compatible with fibrous dysplasia.
