Ulcerative lesion on lower lip

Abstract

A 34-year-old man was referred to our service complaining about an ulcerated lesion on the lower lip. During anamnesis, the patient reported fever 3 months previously that resolved through antipyretics, and the lip lesion appeared soon after. Extraoral examination revealed cervical lymphadenopathy in the right submandibular region through palpation of a single painful submandibular lymph node. No changes were observed in other regions. On intraoral examination, there was redness and swelling affecting almost the entire lower lip with sparing of the lip commissures with areas of crusting and ulcerations along the vermilion border.
