What type of oral lesion heals with scarring and is typically found on the lip of a young boy?

The type of oral lesion that heals with scarring and is typically found on the lip of a young boy is a major aphthous ulcer. Major aphthous ulcers, also known as Sutton's disease, are characterized by their larger size and deeper involvement compared to minor aphthous ulcers. They can cause significant pain and discomfort, often occurring on non-keratinized mucosal surfaces, which includes areas such as the inner lip.

One of the distinguishing features of major aphthous ulcers is that they can lead to scarring after healing, which is significant since many other oral lesions typically regenerate without leaving scars. The occurrence in young boys may be attributed to factors such as the prevalence of stress or trauma that can trigger these ulcers in this demographic.

This characteristic of persistent healing with scarring sets major aphthous ulcers apart from other potential lesions like herpes simplex ulcers, which tend to recur but do not typically cause scarring after resolution, or traumatic ulcers, which might heal without scarring unless severely traumatized. Oral lichen planus often presents with characteristic white striae and erosions, and while it can leave scars, it does not typically manifest in a solitary, lip-focused ulceration in a young boy.
