Pediatric oral lesions: a 15-year review from São Paulo, Brazil

Abstract

There are few studies on pediatric oral pathologies in the literature. This study presents data from a review of 2,356 biopsies of young patients (birth to 14 years) received over 15 years (1985-2000) in the Oral Pathology Service at the University of Sao Paulo, Brazil. Information about patients (sex, age, race) and histopathological diagnosis was retrieved. Diagnosis data of 2,356 biopsies were classified into 20 groups.There was no significant difference between male (50.0%) and female (49.0%) patients. White is the predominant race (69.0%), and patients ages were concentrated between 9 and 14 years old (70%). Mucocele was the most frequent (13.5%), followed by dentigerous cyst (6.5%) and fibrous hyperplasia (5.4%). Papilloma and Langerhans cells histiocytosis were the most common non-odontogenic benign and malignant tumors, respectively. In the group of odontogenic tumors, odontoma was the most frequent, and ameloblastoma had a significant incidence (27 cases). These data are important in order to detect differences in geographic areas, diagnosis line tendencies and for clinicians to perform judgment to evaluate of the pediatric patients before the biopsy and management of pediatric oral lesions.

Odontogenic tumors: a 14-year retrospective study in Santa Catarina, Brazil

“…5,7,13,14,19,[22][23][24] Odontoma, also considered a frequent OT, was the third-most common lesion in our study. In some studies, it is shown to be the most frequent lesion, 5,6,12,22 although our study is more consistent with those conducted by Avelar et al, 18 Fernandes et al, 23 Jing et al, 19 Jones and Franklin, 9 Olgac et al, 14 Osterne et al, 13 and Saghravanian et al 15 in presenting an incidence of approximately 17%. Our study is in agreement with the data found in the literature that show a higher frequency in female patients.…”

“…OTs are lesions rarely observed in dentistry clinics, [5][6][7]9,12,13 and their frequency was 3% in our study, with a mean age of 30 years, varying between 5 and 75 years, and occurring more often in male patients. Their main location was in the posterior mandibular area.…”

“…These data agree with findings from other studies performed in different countries. 5,6,[13][14][15] Our study demonstrated that most of the lesions occurred in Caucasian patients, which can be easily explained, as Caucasians correspond to 85.7% of the entire population in the Santa Catarina State according to data from the Instituto Brasileiro de Geografia e Estatística -IBGE. 16 KCOT was the most frequent lesion observed in our study, comprising 51% of all lesions.…”

Oral and Maxillofacial Complex Lesions in Adolescents: A Retrospective Study of 20 Years

“…In this study only adolescents were selected and all lesions that occurred were investigated and diagnosed by clinical and/or histopathological examination, whereas 49.46% of them were exclusively diagnosed by clinical examination. However most studies conclude their diagnosis based on the histopathological analysis (Chen et al, 1998;Sousa et al, 2002;Jones & Franklin;Dhanuthai et al, 2007;Wang et al).…”

Unicystic Ameloblastoma presenting in Gardner's Syndrome: A case report

“…Eighty percent of ameloblastomas present in the mandible of which 70 percent occur in the posterior molar region. [7][8][9] These lesions can be locally aggressive if left untreated and thus early diagnosis is vital to minimise the extent of surgery Aetiology is uncertain; it has however been suggested that they may arise in dentigerous cysts, within remnants of the dental lamina or the basal layer of the oral mucosal epithelium. 10,11 Suggested predisposing factors have included irritation in the form of extractions, caries, trauma, infection, tooth eruption, nutritional deficits and viral infection especially Human Papilloma Virus (HPV).…”
