A Nodular Lesion of the Tongue

A 45-year old white male was referred with a chief complaint of a solitary, occasionally painful soft tissue nodule that had been present for approximately 6 months on the right tongue dorsum. He stated he initially noted the lesion after minor trauma to the site. He anticipated spontaneous resolution, but the lesion has persisted and remained stable in size for the past 4 months.
