RESUMEN
Lipomas are benign soft tissue tumors frequently observed throughout the body. Lipomas rarely cause health concerns; however, when symptomatic, it is often related to their location and size. A 65-year-old male patient presented with a non-tender, enlarging mass in the anterior floor of the mouth, which was otherwise asymptomatic. Computed tomography evaluation revealed an unusually large hypolucent mass, posterior to the inner table of the right anterior mandible. Surgical excision was uncomplicated. Upon follow-up, the right anterior floor of the mouth wound healed without compromise of the lingual or hypoglossal nerves or Wharton's duct. This discussion highlights the infrequent occurrence of lipomas in the oral cavity, particularly in the floor of the mouth, including patient presentation, preoperative evaluation, and surgical planning.
