SQUAMOUS CELL CARCINOMA ON THE BUCCAL MUCOSA IN A FEMALE PATIENT: A CASE REPORT
OOOO Volume 129, Number 1 had a verrucous surface, was sessile, white, rough, with defined edges and 2 cm in size. On the right superior anterior alveolar ridge, a white lesion was found with plain characteristics, was noted to be painless and with defined edges 3 cm in size. Diagnostic hypotheses were SCC, verrucous carcinoma, and PVL. Two incisional biopsies were performed on different areas. The histopathologic examination confirmed SCC on the inferior area and leukoplakia with moderate epithelial dysplasia on the superior area. The leukoplakia was removed and the patient was forwarded to a head and neck surgeon to treat the SCC and these patients are under continued monitoring.
ACQUIRED IMMUNODEFICIENCY SYNDROME ORAL MANIFESTATIONS: A CASE SERIES. TATIELE FREITAS KUCZYNSKI, YUMI NIIHO FRANZ, ANA LUISA HOMEM DE CARVALHO, MARCIA RODRIGUES PAYERAS, FABIO LUIZ DAL MORO MAITO and, NATALIA BATISTA DAROIT Acquired immunodeficiency syndrome (AIDS) is a chronic systemic disease. This condition can be manifested if the patient is infected by the human immunodeficiency virus (HIV). This virus attacks the immune system and interferes in the host resistance. Consequently, infected organisms become immunosuppressed and susceptible to acquiring other opportunistic infections and injuries. The HIV-related diseases most frequent in the oral cavity are candidiasis, gingivitis, oral hairy leukoplakia, herpes simplex, and Kaposi sarcoma. The objective of this study is to report 4 clinical cases of patients with the oral disorders listed above. AIDS oral manifestations may represent the first clinical signs of HIV infection. Therefore, knowledge of oral lesions associated with HIV infection is extremely important for the oral surgeon. Based on this, the health professional can make the HIV diagnosis of this complex systemic disease, in some cases not previously diagnosed.
EXTENSIVE PARACOCCIDIOIDOMYCOSIS ORAL MANIFESTATION ASSOCIATED WITH SYSTEMIC SYPHILIS: A CASE REPORT. YUMI NIIHO FRANZ, TATIELE FREITAS KUCZYNSKI, ANA LUISA HOMEM DE CARVALHO, MARCIA RODRIGUES PAYERAS, FABIO LUIZ DAL MORO MAITO and, NATALIA BATISTA DAROIT Paracoccidioidomycosis is a disease caused by the dimorphic fungus Paracoccidioides brasiliensis. A 46-year-old male patient, chronic smoker, crack and cocaine user reported a history of completed syphilis treatment 5 years ago. The patient described a recent history of a mouth burn secondary to chlorine. Clinical examination revealed moriform ulcers with hemorrhagic dots on the surface on the lower labial mucosa, buccal mucosa, and hard palate. The histopathologic diagnosis of this incisional biopsy was paracoccidioidomycosis. Venereal Disease Research Laboratory (VDRL) and fluorescent treponemal antibody absorption (FTA-ABS) were considered reactant in both serologic investigations. The patient was referred for treatment of both infections. After 7 months of drug therapy, the oral lesions regressed, and the patient did not report more symptoms. The present case emphasizes the importance of the detailed clinical examination and complementary tests. The presence of coinfections is highlighted, because the patient’s habits could favor these contaminations. The oral surgeon knowledge about these diseases allows for prompt diagnosis and minimizes morbidity.

SQUAMOUS CELL CARCINOMA ON THE BUCCAL MUCOSA IN A FEMALE PATIENT: A CASE REPORT. GLAUCIA ZIMERMANN, ^ CLAUDIA CORTES MAYRINK, CARLA RENATA PETILLO, ROSEMIRO DE MENEZES MACIEL, SARAH APARECIDA ^ PIRES and, MONICA ^ e ANTERO, FABIO RAMOA SIMOES ISRAEL Squamous cell carcinoma is a malignant neoplasm originating in the epithelial tissue with multifactorial etiology, including tobacco, alcohol, and ultraviolet radiation. The aim of this study is to report a case in which its location is unusual, the buccal mucosa. A 94-year-old woman came to the stomatology clinic complaining that she had a lesion with a burning sensation on the left side of the buccal mucosa. During the anamnesis, she reported being hypertensive, having dyslipidemia and Alzheimer disease; in addition, she denied a history of smoking or alcohol use. During the physical examination an exophytic lesion was observed, with an undefined edge, verrucous surface, sessile, secluded, whitish-red coloration, firm consistency, and approximately 5 cm in size. The diagnostic hypotheses were verrucous carcinoma and squamous cell carcinoma. An incisional biopsy was performed and histopathologic exam showed squamous cell carcinoma. The patient was referred for surgical treatment and after 6 months no signs of return were observed.
ORAL LYMPHOEPITHELIAL CYST: A CASE REPORT. CONSTANZA ULLOA BEQUER, ANA MARIA SALAZAR ROA, MAURICIO CARRASCO RODRIGUEZ and, PAULINA CUBILLOS GONZALEZ A 62-year-old female patient was referred for an evaluation of an asymptomatic lesion of approximately 2 years’ duration. The patient presented with a nodule on the ventral surface of the tongue, with a sessile base, smooth, and with nonulcerated overlying mucosa but with a slightly yellow coloration. An excisional biopsy was performed. In the macroscopic examination, the sample was divided symmetrically, causing the sample to release a dense whitish secretion. Microscopically, a cystic cavity was observed and delineated by a parakeratinized stratified squamous epithelium. The cystic wall was constituted by lymphoid tissue with randomly arranged germinal centers. Keratin and desquamated epithelial cells were present in the cystic lumen. With these findings, the diagnosis was oral lymphoepithelial cyst. In the following controls, a postoperative wound is observed in the process of normal healing. The case is reported under the informed consent of the patient.
