This is a 33-year-old male who presented with a smooth-surfaced, pink, firm and movable nodule on the upper lip, left side (Figure 1). It is of two years' duration. It is around two cm in diameter at its greatest dimension and is not painful. The swelling is otherwise asymptomatic with an intact mucosa.
