This article describes a case of giant cell fibroma in a 3-year-old boy, which is an uncommon age for this lesion. The cause of this pathology has not been determined. The lesion was excised by electro surgery and submitted to a histological exam, which confirmed the diagnosis. No recurrence was observed. Pediatric dentists should be capable to diagnose and(More)
OBJECTIVE To investigate the prevalence of HPV infections in the oral and cervical mucosa of HIV-positive and HIV-negative women attending a sexual health clinic. METHODS One-hundred HIV-positive women and 100 HIV-negative women were recruited from a sexual health clinic in São Paulo, Brazil. All participants were given an oral and cervical examination.(More)
The purpose of this study was to determine the prevalence of Epstein-Barr virus (EBV)-DNA in the oral mucosa of renal transplant patients and observe the efficacy of mouth rinses with phosphate-buffered saline (PBS) to eliminate EBV present in the saliva. Lingual, gingival, and buccal cytobrushings were obtained from normal oral mucosa of 10 renal(More)
We report here the existence of a novel subset of langerin (CD207)-positive, immature dendritic cells (DCs) (CD83(neg) ) abundantly infiltrating Epstein Barr virus (EBV)-infected areas in tonsil, Hodgkin lymphoma and nasopharyngeal carcinoma. These CD207(+) DCs differ from conventional epidermal Langerhans cells in their lack of CD1a and CCR6 and their(More)
Central odontogenic fibroma World Health Organization (WHO)-type (OFWT) is a rare lesion that has differential diagnosis with other radiolucent periapical lesions. It has a slow growth and is usually an asymptomatic lesion found in routine examinations. We report a case of a central OFWT occurring in the maxilla, for which the first symptom was teeth(More)
In recent years, the incidence of oral opportunistic infections has increased, partly due to the widespread implementation of organ and bone marrow transplantation and the increase in the prevalence of human immunodeficiency virus (HIV) infection. Cytology can be used as a rapid, inexpensive and simple routine procedure in diagnosing infectious diseases of(More)
OBJECTIVE To establish a definitive diagnosis of oral hairy leukoplakia (OHL) by in situ hybridization for Epstein-Barr virus (EBV) detection with liquid-based cytology (LBC), using the ThinPrep® Pap Test, and to compare its efficacy with the traditional method of performing biopsy. METHODS Thirty-three individuals divided into three groups were included(More)
Opportunistic infections may affect the oral mucosa of patients undergoing radio/chemotherapy through exacerbation of oral mucositis. The aim of this study is to evaluate the oral shedding of all eight human herpesviruses and its possible association with oral mucositis. In this prospective cohort study, we analyzed oral rinse samples, collected weekly,(More)
AIM Saliva can play an important role in human herpesvirus-8 (HHV-8) transmission in endemic regions for Kaposi's sarcoma (KS). Little is known about HHV-8 oral shedding in immunocompetent individuals from non-endemic regions for KS. METHODS We conducted a prospective study of HHV-8 salivary excretion among 59 healthy, immunocompetent individuals from São(More)
Plasmablastic lymphoma (PBL) is an HIV-associated non-Hodgkin's lymphoma that primarily affects the oral cavity. We describe the case of an HIV patient with a lesion in the maxilla that lasted four months. He was diagnosed with PBL and received highly active antiretroviral therapy as well as chemotherapy and local radiotherapy. The lesion regressed after(More)
