Recurrent aphthous
stomatitis (RAS)

RAS is an immune-mediated reaction that's triggered by many factors,
including medications, certain
foods, trauma,
s t r e s s , h o rmonal changes,
infections and
hematologic abnormalities. RAS may also be associated
with systemic conditions like Behçet
syndrome, celiac disease and cyclic
neutropenia. These ulcerations commonly occur on nonkeratinized tissue
and generally last 7-14 days. They are
usually 3-10mm in diameter and heal
without scarring. Children and young
adults are the most affected.

Pseudomembranous
candidiasis

This is the most
common form of
candidal infection, often referred
to as "thrush."
Sy mptoms a re
generally mild. Presence of infection is
dependent on several factors, including
host immune status and the oral mucosal
environment.

6

Mucocele
A mucocele is a common oral lesion
caused by a ruptured salivary gland
duct. The mucin then spills into the surrounding soft
tissues, forming
a dome-shaped,
fluctuant swelli ng. It may
increase or
decrease in size.
Mucoceles are often caused by trauma
to the site and, as such, the lower lip is
a common site of involvement. While
some may rupture and resolve on their
own, most require local surgical excision.

Common mistakes:
Aphthous ulcerations are often misdiagnosed
as recurrent herpes simplex infections.

Oral lichen planus, reticular type
Lichen planus is an immunemediated mucocutaneous disease that
occurs through a T-cell-mediated process.
It is more common in women and may
affect the skin, presenting as purple,
pruritic, polygonal papules.
There are four forms: reticular,
erosive, plaque-type and bullous. The
reticular form is
most common,
presenting with
characteristic,
interlacing
w h it e s t r i a e
(Wickham
striae), usually on the posterior buccal
mucosae. Reticular lichen planus is
not symptomatic, but the erosive form
usually presents with painful lesions.

Diagnostic pearls
* Follow a systematic
approach when evaluating
an oral lesion. Recognize
normal tissue versus
abnormal tissue.

* Neoplasms are abnormal
growths of tissue, and these
may be benign or malignant.
Reactive lesions may
occur because of trauma,
infection, inflammation or
* Understand how to establish autoimmunity.

Lichen planus is often misdiagnosed
as oral candidiasis.
