Extenso lipoma com localização incomum e 10 anos de evolução: relato de caso

Abstract

Lipoma is a benign fat tumor that represents the most common mesenchymal neoplasm and can affect the head and neck region. They are more frequent in obese individuals, however, the metabolism of lipomas is independent of normal body fat. They are characterized as nodular swellings with a smooth surface and soft consistency that can be sessile or pedunculated, are usually asymptomatic and less common sites of involvement include the tongue, floor of the mouth and lips. Thus, this article aims to report a clinical case of lipoma with years of evolution and located in an unusual region. The female patient was referred to the Stomatology Clinic of the Faculty of Dentistry of the UFC-Sobral Campus, reporting that she had had the lesion since 2010 and stating that she had never undergone previous treatment and that there was no known causal factor. On clinical examination, a yellowish nodular lesion measuring about 1.5cm was observed, located in the region of the lateral border, belly and dorsum of the tongue on the right side, compatible with the diagnostic hypothesis of lipoma. In this sense, based on the anamnesis and clinical findings, it was decided to perform an excisional biopsy to confirm the diagnosis. With the results of the biopsy, the diagnostic hypothesis was confirmed, and therefore, there was no need for additional treatments. Therefore, from this case it can be seen that the lipoma can be an injury that can last for several years without major complications, however it can reach large dimensions and in these cases surgical treatment is necessary.
