CHONDROLIPOMA IN AN UNCOMMON LOCATION: CASE REPORT. KHALIL FERNANDES VIANA, ERASMO BERNARDO MARINHO, STHEFANE GOMES FEITOSA, ROBERTA BARROSO CAVALCANTE, EVELINE TURATTI, FABRICIO BITU SOUSA and, KARUZA MARIA ALVES PEREIRA Chondrolipoma is a benign mesenchymal tumor that may occur anywhere in the body, such as soft tissues of the skeletal system, but is rarely seen in oral cavity. This lesion is a rare histologic variant of the lipoma with uncertain pathogenesis. A 68-year-old woman presented a nodule that was sessile, erythematous, and measured 1 cm in the region of the middle line in the upper alveolar ridge with complaint of painful symptomatology and bleeding, associated with the use of poorly adapted upper prosthesis. Excisional biopsy was performed and histopathologic examination revealed a proliferation of mature adipocytes interspersed with myxoid connective tissue with focus of cartilaginous tissue, being conclusive as a chondrolipoma. The histopathologic diagnosis of chondrolipoma is determinant, especially in a lesion in an unusual location. The treatment of choice for these tumors consists of surgical excision. The patient is under follow-up with no recurrence of the lesion during a 1-year follow-up period.
DENTAL CARE TO PATIENTS WITH RARE CLINICAL FIDINGS OF GOLTZ SYNDROME—CASE REPORT. LIA DE VASCONCELOS ROCHA, JOSE VITOR MOTA LEMOS, e e IANA ARAGAO MAGALHAES, JULIANA XIMENES DAMASCENO, MARILIA LEITE DIAS, THALES SALLES ANGELIM VIANA and, ANYA PIMENTEL GOMES FERNANDES VIEIRA MEYER Goltz syndrome or focal dermal hypoplasia is a rare hereditary genetic disease of the dominant X chromosome. Multisystemic manifestations of a wide phenotypic variety with involvement of the maxillomandibular region are observed. A 6-year-old female patient with the syndrome sought a specialized dental service, presenting as main complaint the need for dental treatment for extensive carious lesions. Physical and intraoral examination showed delayed tooth eruption, agenesis, enamel hypoplasia, and atypical anatomy of the teeth as well as unusual clinical findings of the syndrome, such as abnormal tongue morphology and cleft lip and palate. Occlusal and panoramic radiographies were performed. The care plan began with health promotion, followed by instruction in oral hygiene for parents and children, prophylaxis, topical application of fluoride, restorative treatments, exodontia, and laser therapy. Management techniques such as positive reinforcement, voice control, say-show-making, and awards were used. Currently, the patient is being followed up.
FACTITIOUS CHEILITS: A CASE REPORT. LETICIA ALMEIDA OLIVEIRA, PAULA LIMA FREITAS, LETICIA ALECRIM DE SOUZA, LIGIA GONZAGA FERNANDES, KARINE CARLI FRANK, VICTOR PEREZ TEIXEIRA and, JOSE NARCISO ROSA e JUNIOR ASSUNC ¸ AO A 24-year-old white man, nonsmoker and nonalcoholic, presented to the stomatology ambulatory department with the
OOOO January 2020 complaint of desquamation on his lips that started 9 years ago. On intraoral examination, lesions were observed in all extension of the upper and lower lips, sometimes of yellowish color, sometimes whitish, with painless and crusted areas. He reported putting his lips between his teeth in a chronic way and a habit of nibbling. The patient performed previous topical treatments without resolution of the condition. After an incisional biopsy with results that showed an unspecific chronic inflammatory process and the associated clinical examination, the final diagnosis was factitious cheilitis. After diagnosis, manipulated topical treatment of 9 g Vaseline + 1 g lanolin + 2 g glycerin, in gel, was instituted for 2 months, and total lesion regression was observed. The patient has been followed up for 6 months, evolving with normal aspects in the labial mucosa.
INTRAOSSEOUS SYNOVIAL SARCOMA OF THE MANDIBLE: A CASE REPORT. EVELIN JANNER, EDUARDO ZAMBALDI DA CRUZ, ANDERSON ABDO RODRIGUES, LUCAS NOVAES TEIXEIRA, ANA CLAUDIA GARCIA ROSA, FABRICIO PASSADOR-SANTOS and, VERA CAVALCANTI DE ARAUJO A 22-year-old man reported a painful swelling on the left side of the mandible for the last 7 months. The patient was otherwise healthy. Radiologic features revealed an extensive multilocular radiolucency involving the left side of the body and ramus of the mandible. Microscopic examination showed a fragment of neoplasm composed by areas with different levels of cellularity. The neoplastic cells exhibited a fusiform morphology with vesicular nuclei and evident nucleolus. Immunohistochemistry analysis revealed that neoplastic cells were positive for cytokeratins (AE1/AE3, focal areas), cytokeratin 7 (focal areas), vimentin (diffusely), CD-99 (focal areas), transducin-like enhancer protein 1 (TLE-1, diffusely) and negative for CD-34, S-100, smooth muscle actin, and HHF-35. These findings in combination supported the diagnosis of synovial sarcoma. The patient was referred for treatment, and hemimandibulectomy on the left side with wide surgical margins is the surgical approach planned.
HEAD AND NECK AMYLOIDOSIS AS THE FIRST MANIFESTATION OF MULTIPLE MYELOMA—A CASE REPORT. PAOLA ARISTIZABAL ARBOLEDA, NATALIA RANGEL PALMIER, JESSICA MONTENEGRO FONSECA, ISADORA FERRARI TEIXEIRA, PABLO AGUSTIN VARGAS, MARCIO AJUDARTE LOPES and, ALAN ROGER DOS SANTOSSILVA A 76-year-old man with medical history of anemia was referred for clinical investigation of hoarseness and dysphagia over the last 2 years. Extraoral head and neck examination revealed diffuse hardened skin. Intraoral examination revealed macroglossia with restricted tongue movement and hardening of the lower lip mucosa. Digital panoramic radiograph revealed discreet radiolucent areas affecting the mandible. Incisional biopsy was performed under local anesthesia on the tongue and lower lip. Histopathologic analysis revealed a deposition of hyaline material, mainly surrounding minor salivary glands. Congo red histochemical stain showed apple-green birefringence under polarized light microscopy, confirming the diagnosis of amyloidosis. Laboratory examinations were performed, and the patient was referred to a hematooncologist, who confirmed the diagnosis
