Abstract

Purpose: To report a rare tumor mimicking a gingival inflammatory lesion focusing not only on its characteristics, but making a deepened differential diagnosis with inflammatory lesions, in terms to collaborate for an accurate diagnosis as possible by the clinicians. Case description: A 20-year-old woman presented an asymptomatic sessile gingival mass - between teeth 32 and 33 - with 1 year of duration. An excisional biopsy was performed and the histological examination revealed an odontogenic neoplasm characterized by the presence of islands of apparently inactive odontogenic epithelium, in a fibromyxoid stroma; all features consistent with the diagnosis of peripheral odontogenic fibroma. Conclusion: Peripheral odontogenic fibroma is often misdiagnosed as an inflammatory lesion. However, the existence of particularities of each lesion can guide the clinical to a more efficient diagnosis. Excisional biopsy is their treatment of choice, whereas; the peripheral odontogenic fibroma prognosis may be different given its rarity and its few data about long-term follow-up

Keywords

Resumo

Objetivo: Relatar um caso de um tumor raro imitando uma lesão gengival inflamatória tendo em foco não apenas as suas características, mas realizando um diagnóstico diferencial aprofundado com as lesões inflamatórias; a fim de colaborar para um diagnóstico mais eficiente por parte dos clínicos. Descrição do caso: Um paciente do sexo feminino, de 20 anos de idade apresentava uma massa gengival séssil e assintomática - entre os dentes 32 e 33 - com duração aproximada de 1 ano. Após biópsia excisional, a análise histológica revelou um neoplasma odontogênico caracterizado pela presença de ilhas de epitélio odontogênico aparentemente inativo, localizado em um estroma fibro-mixóide. Características consistentes com o diagnóstico de fibroma odontogênico periférico. Conclusão: O fibroma odontogênico periférico é freqüentemente confundido com uma lesão reacional inflamatória. No entanto, a presença de particularidades de cada lesão pode auxiliar o clínico, a fim de se obter um diagnóstico mais preciso. A biópsia excisional é o tratamento mais indicado. Porém, o prognóstico do fibroma odontogênico periférico pode ser diferente, devido a sua raridade e pouca informação sobre seu acompanhamento de longo prazo.
