RESIDUAL CYST OR KERATOCYSTIC ODONTOGENIC TUMOR: THE IMPORTANCE OF HISTOPATHOLOGY
OOOO Volume 124, Number 2 A melanoderma 11-year-old male patient, sought care complaining of tongue lesions that did not heal. During anamnesis, the patient’s father reported that he suffered from stomach problems and was using DigesilÒ, and since his childhood he presented papular mucocutaneous lesions. An extraoral physical examination, it was observed that the patient had flat hyperkeratotic papules in the palmoplantar regions. The intraoral examination revealed whitish and asymptomatic papules, restricted to the tongue dorsum that coalesced acquiring aspect of “paving stones.” The brain magnetic resonance did not show abnormalities. Based on clinical findings, the patient was diagnosed with Cowden’s syndrome. The intraoral lesions were treated with application of 60% trichloroacetic acid. The early diagnosis of Cowden’s syndrome requires careful monitoring of the patient to detect early malignant neoplasms commonly associated with this pathological entity.
CPP311 - MAXILLARY CALCIFYING CYSTIC ODONTOGENIC TUMOR ASSOCIATED WITH COMPLEX ODONTOMA: CASE REPORT. ISRAEL LEAL CAVALCANTE, CAIO CÉSAR DA SILVA BARROS, HUGO COSTA-NETO, DIEGO SANTIAGO DE MENDONÇA, RENATA CORDEIRO TEIXEIRA MEDEIROS, ROBERTA BARROSO CAVALCANTE. The calcifying cystic odontogenic tumor (CCOT) or Gorlin cyst is a rare lesion, described as a benign cystic odontogenic neoplasm. It usually occurs in young adults, between the third and fourth decade of life and presents variable clinical behavior. It may also be associated with odontoma, ameloblastoma or impacted teeth. Recurrences are uncommon and malignant behavior is rare. In this study, it is reported a case of a 35-year-old male patient, presenting with an intraosseous lesion in an occasional panoramic radiograph in the anterior maxilla. Lesion was asymptomatic and the radiograph showed a radiolucent unilocular image, as well as multiple radiopaque structures within the lesion, located between teeth 13 and 15. Teeth were unharmed and were not associated with the lesion. Histopathologic analysis from excisional biopsy pointed to the diagnosis of CCOT associated with Odontoma complex. The patient is currently under active follow-up.

VÍTOR CASTRO DE JESUS, TIAGO VEIGA DE BRITTO FREITAS, MYRIAN SALLES VIEIRA, TIAGO NOVAES PINHEIRO, LIONEY NOBRE CABRAL, MARIA DE FÁTIMA RIBEIRO RODRIGUES. This paper proposes to present a case of a male patient, 51 years old, melanoderma, which extracted the teeth 36 and 37 years ago, realizing swelling, facial pain and asymmetry, 2 months before consultation. The CT scan showed a hypodense image in the region indicated. It was suggested diagnosis of residual cyst or odontogenic keratocystic tumor. Before the surgery, lesion puncture was performed, being sucked blood and citrine liquid, evolving to excisional biopsy, with removal of cystic aspect lesion, then sent for histopathologic examination. The histopathology reported presence of coated hollow part of stratified squamous epithelium with 3-5 layers of cells, mild inflammatory infiltrate and cholesterol crystals, with diagnostic of residual cyst. One week after surgery, patient reported no pain in the surgical area and was perceived improvement in his facial symmetry. After 1 year, there was no new complaint.

Myoepithelioma is a rare benign neoplasm of salivary gland and relatively more aggressive than pleomorphic adenoma. The treatment consist of surgical removal of the lesion. Herein we report a case of a 69-year-old female patient presenting with a well-circumscribed firm mass that measured approximately 2 cm x 1 cm in the soft palate. The mucosa covering the mass was reddish. Radiographic examination showed normal aspects of adjacent bone. An incisional biopsy was performed and histological sections exhibited a solid epithelial tumor with a glandular differentiation characterized by cells with well-defined cytoplasmatic borders, oval and periphery displaced nuclei, with plasmacytoid appearance. These cells were organized in nests, islands and cords separated by hyaline stroma. There were no ductal or glandular elements, as well as atypia or necrosis in the sections studied. The surgical removal of the lesion was performed and the patient is under follow-up for about 1 year without recurrence.

Mucoceles are the most common lesion of oral cavity, a term used to name lesions that can be classified as extravasation or retention of mucus phenomena. The present case aims to report a 14 mm diameter salivary duct cyst in a 34-year-old female patient. Excisional biopsy was made and the piece was sent for histopathologic evaluation. Based on clinical, radiologic and histopathologic findings the diagnosis was salivary duct cyst. The patient has not shown signs of relapse after 1 year.
CPP315 - CEMENTOBLASTOMA: CASE REPORT. MISSUZY PORTUGAL BRANDÃO, MAXINE ENNATA ALVES DE ALMEIDA, RODRIGO MAROCCHIO PAVANE. W.C.F. male patient, melanoderma sought dental care reporting onset of symptomatic tumor in the lower left molar region for 6 months, with progressive growth without inflammatory signs. He reported having suffered trauma in this region, with the formation of edema and hematoma. Clinical examination noticed facial asymmetry and swelling in the buccal groove bottom with about 2 cm in diameter and slightly reddened mucosa. The patient underwent radiographic examinations that showed radiopaque lesion well-defined radiolucent halo in the region of the roots of the second and third molar left inferior, which led to H.D. benign cementoblastoma. Incisional biopsy was performed in October 2006, with the result of A.P. cementoblastoma. On May, 2007, the patient was operated for resection of intraosseous tumor of the jaw under general anesthesia, which was enucleated injury along the dental elements involved in this, the most conservative way possible.
