HENRIQUE LOPES DOMINGUETE, LUCIANA YAMAMOTO ALMEIDA, LUCAS RIBEIRO TEIXEIRA, KAMILA PRADO PEREIRA GRACIANO, JOSE DIAS DA SILVA-NETO and, JORGE ESQUICHE LEON Epidermoid cysts (ECs) are rare and occur in the head and neck region with an incidence from 1.6% to 7%. In the oral cavity, EC represents less than 0.01% of all cysts. To date, approximately 80 EC cases have been reported. We report a case of a 26-year-old man who developed a large EC in the midline floor of the mouth, leading to speech and swallowing difficulties and causing swelling in the submental region. Ultrasonography and fine needle aspiration confirmed the cystic nature of the lesion. The lesion was surgically excised by intraoral approach, and microscopically revealed an EC associated with extensive elastofibromatous changes in the cystic capsule. The pathogenesis of the abnormal deposition of elastic fibers is unknown; however, degenerative phenomenon, disturbed production, genetic predisposition, or trauma have been considered. To the best of our knowledge, this is the first report of elastofibromatous changes in an intraoral EC.
A CASE REPORT OF CRANIOFACIAL FIBROUS DYSPLASIA. MARIANA SATURNINO DE NORONHA, CAMILA DE NAZARE ALVES DE OLIVEIRA KATO, FELIPE PAIVA FONSECA and, RICARDO ALVES MESQUITA Craniofacial fibrous dysplasia (CFD) is a nonneoplasic lesion, characterized by the substitution of normal osseous tissue by proliferating fibrous stroma and immature bone tissue. CFD usually occurs by 10 years of age and the progression commonly manifests in adulthood. A 20-year-old male patient presented with a painless enlargement in the maxilla with indeterminate evolution time. Clinical examination revealed a swelling extending to the right side of maxilla and orbital floor. Radiographic aspects showed borders contiguous with normal adjacent bone and a ground-glass appearance. Incisional biopsy was performed. Microscopic examination showed lamellar bone trabeculae, varied in size, arranged parallel to fibrous connective tissue, compatible with benign fibro-osseous lesion. Multiplane sections on cone beam computed tomography showed an extensive orbital floor and maxillary involvement and increased dimensions of the occiput, base of the skull, hard palate, and zygoma. A final diagnosis was craniofacial fibrous dysplasia. Patient is under followup care and will undergo corrective surgery. Support: FAPEMIG.
GINGIVAL SQUAMOUS CELL CARCINOMA AND ENVIRONMENTAL RISK FACTORS LEONARDI, FOR ORAL CANCER. NICOLAS JUAN IGNACIO PANICO, GERARDO GILLIGAN and, RENE LUIS PANICO The aim of this work is to present a case of a 74-year-old man who visited the Oral Medicine Department, Dentistry College, at the Catholic University of Cordoba with a gum lesion involving the lower incisors and the left canine. During oral examination, a gingival mass with an ulcerated surface of 6 months’ duration was noted. The lesion had a history of painless growth and displayed no dental mobility, however, it did exhibit a slight tendency to bleed. The patient was born and lived in a village near Cordoba, Argentina, which is characterized by arsenic contamination of groundwater. Classic risk factors for oral cancer such as tobacco consumption and alcohol were not found.
OOOO January 2020 Oral squamous cell carcinoma was diagnosed after an incisional biopsy. Arsenic, classified by the International Agency for Research on Cancer as a human chemical carcinogen, is present in groundwater of some regions of South America and it could have contributed to oral carcinogenesis as in this case.
OSTEOMYELITIS IN A PATIENT WITH PYCNODYSOSTOSIS: A RARE CASE REPORT AND REVIEW OF THE LITERATURE. JOSE ALCIDES ALMEIDA DE ARRUDA, EDUARDO MORATO DE OLIVEIRA, POLIANNE ALVES MENDES NASCIMENTO, LAUREN FRENZEL SCHUCH, AMALIA MORENO, LEANDRO NAPIER DE SOUZA and, RICARDO ALVES MESQUITA Pycnodysostosis (PYCD) is a rare autosomal recessive disease occurring due to a mutation in the gene that codes for the enzyme cathepsin K. Osteomyelitis of the jaws is a common complication of the PYCD. A 30-year-old female patient with PYCD presented with mandibular osteomyelitis which was treated by sequestrectomy and with a buccal fat pad as free graft (BFPFG) to fill the bone defect. The 24-month of follow-up demonstrates clinical and radiographic healing. A literature search was undertaken in Medline (through PubMed) in March of 2018 on PYCD case reports. Seventeen contributions were included in this study and discussed. To the best of our knowledge, this is the first case using BFPFG in the management of osteomyelitis of the jaws in a patient with PYCD. Despite the good results, further studies using BFPFG as adjuvant therapy for the management of jaw osteomyelitis are necessary to elucidate its clinical efficiency and safety. Support: FAPEMIG.
A CUSTOM-MADE OCULAR PROSTHESIS FOR A PATIENT AFFECTED BY HERPES ZOSTER: A CASE REPORT. LARISSA SANTOS FARIA, LUISA FERNANDES MONKEN, LUIZA VALE COELHO, MATHEUS SILVA COSTA, JOSE ALCIDES ALMEIDA ARRUDA, RICARDO ALVES MESQUITA and, AMALIA MORENO The ocular prosthesis functions to repair a loss or deformity of the ocular globe. Prosthetic rehabilitations destined for anophthalmic cavities that suffered cicatricial retraction represent a challenge during fabrication since they often need to be reduced due to atrophy of the cavity and simultaneously need to have a good aesthetic appearance regarding contour and artificial iris. This report describes an unusual ocular prosthetic rehabilitation of a 77-year-old patient with an atrophic anophthalmic cavity due to herpes zoster induced loss. The steps in the creation of the ocular prosthesis involved cavity impression, artificial iris painting, wax adaptation, and laboratory processing and installation. The treatment focus included: comfort and adaptation during use, satisfactory retention, good aesthetic appearance, and achievement of total eye closure while wearing the ocular prosthesis. There was reestablishment of facial harmony and, consequently, maintenance of the functional and anatomic integrity of the cavity after a follow-up period of 6 months. Support: FAPEMIG.
