MAXILLARY CAVERNOUS HEMANGIOMA IN THE BUCCAL SULCUS: CASE REPORT
OOOO Volume 124, Number 2 Rhabdomyosarcoma (RMS) accounts for approximately half of all pediatric soft tissue sarcomas and 15% of all pediatric solid tumors. RMS is divided into 5 major histologic categories: embryonal, alveolar, botryoid embryonal, spindle cell embryonal, and anaplastic. Treatment is determined by the extent of disease, ease of resectability, and precise site. Superficially placed tumors can be managed either with excision and relatively non-toxic adjuvant chemotherapy or by biopsy. More deeply placed lesions generally are not removable and require radiation therapy and very aggressive chemotherapy. Herein we report a case of a 9-year-old male patient with maxillary swelling present for 3 months that started with pain episodes in the last 2 weeks. Incisional biopsy was performed and showed variable cell population consisting of small, round tumor cells with hyperchromatic nuclei and of large, polygonal-shaped tumor cells with abundant eosinophilic cytoplasm. Immunohistochemical was positive to Myo-D1, vimentin, and desmin. The patient is under chemotherapy.

MARINA ROLO PINHEIRO DA ROSA, GUSTAVO CAVALCANTI DE ALBUQUERQUE, JOEL MOTTA JUNIOR, MARCELO VINICIUS DE OLIVEIRA, NAÍZA MENEZES MEDEIROS ABRAHIM, JECONIAS CÂMARA, FLÁVIO TENDOLO FAYAD. Herein we report on a case of chronic osteomyelitis with proliferative periostitis with post-removal monitoring of the offending agent. Leukoderma, male patient, 16-year-old, exhibiting increased size in the left jaw region associated with extraction of element 37, mouth opening limitation, facial asymmetry, and skin thickening in the left pre auricular region with an increase over 1 year. Laboratory tests, panoramic radiography, and CT were performed, consisting of intense periosteal reaction in the angle of the left mandible. The patient underwent incisional biopsy of the jaw branch region with intraoral access on external oblique of the mandible. Histopathologic findings were deposition of trabecular bone that have various forms with discrete deposition of collagenous fibers, exhibiting chronic moderate inflammatory infiltrate. Postoperatively of 30 days, the patient presented in good condition and without pain complaints. The prognosis is favorable when the cause is completely removed and adjunct antibiotic therapy performed.
ABSTRACTS Abstracts e73 months after treatment, no tumor recurrence was seen. Enucleation is the appropriate treatment for most COC and, although it has low recurrence rates, it emphasizes the importance of close monitoring of patients.
CPP97 - LINGUAL THYROID: CASE REPORT. MONICA SIMOES ISRAEL, NATHÁLIA DE ALMEIDA FREIRE, ROSEMIRO DE MENEZES MACIEL, WAGNER CHAGAS, MARIA ELIZA BARBOSA RAMOS, SARAH ANTERO. Lingual thyroid is a rare abnormal embryologic development generally located at the base of the tongue. Dysphonia, dysphagia, and dyspnea can be present. Clinically, it appears as a mass at the base of the tongue, pink and firm. Diagnosis is based on clinical examination and imaging. Case report: female patient, 17 years old, presented to the Oral Medicine clinic complaining of dyspnea because of a lesion in the tongue. She had previously gone to a physician who suggested a cystic lesion and requested a CT scan. Extraoral clinical examination did not allow palpation of the thyroid. Intraoral examination showed the presence of a vascularized nodule, 3 cm, smooth surface, at the base of the tongue, suggestive of lingual thyroid. The CT scan was helpful in delineating the size and extent of the lingual thyroid. The patient was referred for medical treatment with suppressive therapy with supplemental thyroid hormone.

HECTON TOMOHIKO OLIVEIRA SATO, TIAGO NOVAES PINHEIRO, YLRI HIROKATSU SATO, LUIZ FELIPE CABRAL DA SILVA MARTINHO, MARCEL KIYOSHI LIMA KIMURA. Herein we report on an unusual case of cavernous hemangioma in the buccal sulcus. A 15-year-old male patient reported to the oral and maxillofacial surgery service complaining of a painless swelling on the left maxilla. Extraoral clinical examination revealed loss of the nasolabial groove. Intraorally, aspects of the lesion comprised a reddish capillary-rich fluctuating fibroelastic nodule in the buccal sulcus close to elements 22e24. Negative puncture procedure preceded the excisional biopsy of the lesion. A dark-red well circumscribed nodule measuring 1.7 1.4 1 cm was sent for histopathologic examination, leading to the diagnosis of cavernous hemangioma. No recurrence of the lesion was detected after 9 months of clinical follow-up.

The calcifying odontogenic cyst (COC) is an uncommon odontogenic lesion, presenting with histopathologic diversity and variable clinical behavior. Herein we report on a case of a male patient, 59 years old, referred for evaluation of an asymptomatic swelling, slow growth, soft consistency areas, in the anterior maxilla, identified 2 years ago. On radiographic examination, there was a radiolucent lesion, unilocular, and relatively well defined. A biopsy was performed and histopathologic examination revealed pathologic cavity presenting cystic lining, with inverted nuclear polarization of the basal layer and similar cells to the stellate reticulum of the enamel organ and numerous ghost cells. Under the diagnosis of COC, marsupialization was performed followed by enucleation of the lesion 2 months after. Six
Orthokeratinized odontogenic cyst (OOC) is an uncommon development of odontogenic cyst comprising about 10% of cases that had previously been coded as odontogenic keratocystic tumors. Herein we report a case of OOC in a 29-year-old female leucoderma patient. The patient reported to the oral medicine service complaining of excruciating pain in element 46 with purulent drainage in a sinus tract located in the distal mucosa of tooth 47. Clinical examination observed swelling in the buccal vestibule on the right mandible. Orthopantomograph revealed multilocular radiolucency, extending from 44 to the ascending ramus of the mandible with hypothesis of keratocystic odontogenic tumor. After endodontic treatment of the teeth 46 and 47, surgical decompression was performed, along with placement of a
