RESUMO
BACKGROUND: Paracoccidioidomycosis (PCM) is the leading cause of death among systemic mycoses in Brazil. On the other hand, oral squamous cell carcinoma (OSCC) is the most prevalent malignant neoplasm of the mouth. Both lesions rarely affect the tongue dorsum and may share similar clinical characteristics. This study aimed to retrieve cases of single oral ulcers diagnosed as PCM or OSCC. MATERIAL AND METHODS: A cross-sectional retrospective study was conducted. All patients who had a single ulcer on dorsum of the tongue and confirmed diagnosis of PCM or OSCC were evaluated. RESULTS: A total of 9 patients (5 women and 4 men) were evaluated, 5 patients had OSCCs (mean age = 69,8 years old), and 4 patients PCM (mean age = 51 years old). Most of the lesions were infiltrated and indurated in the palpation exam. Duration ranged from 1 to 12 months (mean time of 5.2 months and 4.7 months for OSCC and PCM, respectively). OSCC was the main clinical diagnosis hypothesis. CONCLUSIONS: Although uncommon, PCM and OSCC should be considered as a differential diagnosis hypothesis in infiltrated ulcers on the tongue dorsum. Incisional biopsy is mandatory to confirm the diagnosis and indicate the appropriate treatment.

El quiste óseo simple (sinonimia quiste óseo traumático, quisteóseo solitario, quiste óseo hemorrágico) es un pseudoquiste intraóseo desprovistode recubrimiento epitelial con un contenido seroso y/o hemáticoque en ocasiones puede estar ausente.Es una patología poco frecuente que afecta a los huesos maxilares con predilecciónpor el maxilar inferior.El objetivo del presente trabajo es presentar un caso de quiste óseo simpleen maxilar inferior que difiere de los habitualmente encontrados en los huesosmaxilares en cuanto a su presentación clínica, radiográfica e histopatológica(AU)
The simple bone cyst (reported in the literature as traumaticbone cyst, solitary bone cyst, hemorrhagic bone cyst) is anintraosseous pseudocyst devoid of epithelial lining and filled withserous and/or hematic fluid that may also be lacking.Is a an uncommon condition that usually affects the jaws, withpredilection for the lower jaw.The aim of the present work was to report a case of traumatic bonecyst of the jaw that differs from other maxillary bone cysts in itsclinical, radiologic, and histologic presentation(AU)
