MUCOEPIDERMOID CARCINOMA IN THE BUCCAL MUCOSA: A CASE REPORT WITH EMPHASIS ON CLINICAL AND HISTOPATHOLOGIC FEATURES
OOOO Volume 129, Number 1 K€uttner tumor chronic sclerosing sialadenitis is graded in 4 stages, but most of the lesions are usually diagnosed in the 2 intermediary stages. We present a case affecting a female patient, 57 years old and white, who sought the oral medicine service because of a small tendered nodule on the buccal mucosa. Intraoral examination revealed a sessile, painless, and normal-colored fluctuating nodule, resembling a mucocele. After excisional biopsy, the material was submitted to a microscopic evaluation that revealed dilated salivary ducts with ectasia and peripheral fibrosis with intense hyalinization in addition to a discrete periductal lymphocytic infiltrate in the middle of a stroma of adipose tissue of usual appearance. That suggested diagnosis of advanced stage chronic sclerosing sialadenitis (K€ uttner tumor). Further clinical and laboratory examinations ruled out the other immunomediated diseases. Postoperative follow-up showed no signs of recurrence, and the patient was released.
CONSERVATIVE TREATMENT OF SIMPLE BONE CYST IN THE MANDIBLE. TASSIA CAROLINE DA COSTA MENDES, GUILARDO COSTA DE SOUZA, BRENA CAROLINA DE LIMA ^ PINHEIRO, ANTONIO JORGE DE ARAUJO VASCONC, ELOSII, LIONEY NOBRE CABRAL and, TIAGO NOVAES PINHEIRO Conservative treatment with intralesional steroid injection in bone cysts is considered a simple, low-cost technique that preserves vital structures, avoiding great defects to the patient. A 49year-old black woman sought dental care with pain and numbness in the lower left side of the face. Extraoral examination showed tumefaction in the area corresponding to the lower molars. Computed tomography was performed, revealing a circumscribed intraosseous radiolucency in the region of teeth 36. Puncture with cytologic smear had a suggestive diagnosis of simple bone cyst. Minimal surgical access with little amount of soft and hard tissue was submitted to histopathologic examination. During the procedure, intralesional steroid injection was performed as a therapeutic approach. Histopathologic analysis confirmed the diagnosis. Periodical follow-up during 6 months found bone formation into the cystic cavity site, proving the efficacy of the treatment.

A 25-year-old patient presented with a painless swelling on the buccal mucosa. The lesion was a 2-cm firm nodule with purple color. The clinical hypothesis was pleomorphic adenoma, and the material was sent for microscopic analysis, which revealed a malignant salivary gland neoplasia characterized by the proliferation of mucous and epidermoid cells organized in solid nests and cystic structures containing amorphous material. The final diagnosis was mucoepidermoid carcinoma. The patient was sent to a referral oncology service for treatment and is under follow-up.

Case: A 64-year-old female patient came to the stomatology clinic complaining of xerostomia and burning lips. She has controlled hypertension using an antihypertensive, and she has had osteoporosis for 2 years. At the physical examination, there was no noticeable change. Therefore, the patient was diagnosed with BMS. Low-intensity laser therapy was the chosen treatment in addition to orientation for constant hydration. Four sessions were performed weekly using the protocol: Low-intensity laser, 808 nm wavelength, 90 mW of power, 55 J of dosimetry, continuous mode, and punctual application: 15 points in the lower lip, 15 points in the upper lip, and 6 points in large salivary glands. The patient reported total absence of symptomatology after the third session, and she is under follow-up by the stomatology service.
HIGH-POWER DIODE LASER AS A CONSERVATIVE APPROACH FOR ACTINIC CHEILITIS WITH SEVERE DYSPLASIA: CASE REPORT. MILENA THAYS MATIAS DOS SANTOS, LUCAS EMMANUELL DE MORAIS NEVES, DMITRY JOSE DE SANTANA SARMENTO, SANDRA APARECIDA MARINHO, GUSTAVO GOMES AGRIPINO, GUSTAVO PINA GODOY and, SERGIO HENRIQUE GONCALVES ¸ DE CARVALHO A 41-year-old male patient, a white farmer, was referred to the stomatology clinic diagnosed as having actinic cheilitis. Clinically, atrophic and leukoplastic areas were observed throughout the lower lip, and loss of the border between the red lip skin and the cutaneous portion. An incisional biopsy was performed in the leukoplastic area, and histopathologic examination showed atrophic and atypical stratified orthokeratinized pavement epithelium with severe oral epithelial dysplasia. The therapeutic approach was the removal of all leukoplastic areas using the high-intensity diode laser for re-epithelialization of the affected mucosa. Proper follow-up is being performed every 3 months, and after 9 months, no signs of relapse were observed. Because of the potential for malignancy of actinic cheilitis and the presence of dysplastic epithelial alterations, an early approach is justified. The vaporization of the labial tissues with high-intensity diode laser was effective in superficial removal of affected tissues.
