Oral Pathology
Disorders and Tumors of the Oral Cavity and Jaws
The mouth and jaws are comprised of many different types of tissues, such as bone, muscle, glands, and mucosa (the tissue that covers the cheeks, lips, and gums). For various reasons, any of these tissues can develop abnormal growth. This may be caused by heredity, an irritating factor, an injury, an impacted tooth, or a systemic process. Many types of disorders and tumors can develop in these tissues. Some of the more common lesions are shown below.

Lichen planus is a skin disorder which can affect the oral tissues.
The name was given to the disorder in 1869 due to its resemblance to a flat fungus growing on a rock. It is caused by an autoimmune mechanism, and has either a fine, lace-like or an ulcerated appearance.
It is seen most commonly in adult women, and approximately 1% of patients may have skin lesions.
The disorder can be painless or painful. It is usually treated by a topically-applied cortisone ointment, or in severe cases, with cortisone pills. It appears in cycles, and may eventually resolve on its own.
Rare cases can develop into oral cancer, so evaluation by an oral surgeon is recommended.

There are many different lumps and bumps that can appear in the mouth and face. Fortunately, a great majority of these are benign and require fairly minor surgery, most of which can be performed in the surgeon's office.
