A Rare Clinical Case of Lipoma in the Soft Tissues of the Sublingual Space: A Case Report

Summary This report presents clinical case with a histopathologically established lipoma of the sublingual space. Lipomas are benign mesenchymal neoplasms produced by adipocytes. Our search in the literature demonstrated that the development of lipomas in the sublingual space is extremely rare. In the oral cavity, it is seen in less than 5% of patients. In this paper, we describe clinical features, imaging diagnostic and histopathological features. Lipomas are characterized by slow growth and could be asymptomic, therefore diagnosis could be delayed. This report describes and discusses the case of a 64 years-old-man with a formation, located below the left tongue, for a period of 4 years. The patient had repeatedly consulted with Ear-Nose-Throat (ENT) specialists and dentists who recommended surgical treatment. During the last month of the monitoring, the formation had grown significantly and the chewing and speech function had gradually worsened.
