A 43-year-old man was referred to the oral medicine clinic of our university to evaluate
an asymptomatic nodule of unknown duration on the upper lip. There was no history
of trauma, alcoholism, or smoking habits, and his medical history was noncontributory.
Extraoral examination revealed no signs of asymmetry or lymphadenopathy or any skin
color changes. An intraoral examination revealed a 1.0 cm solitary, submucosal, slightly
mobile nodule on the labial mucosa of the upper lip consisting of a mass with a soft
consistency on palpation, covered by intact and normal-colored mucosa (Figure 1).

mucosa on the labial mucosa of the upper lip.
