This is a relatively rare condition whose appearance is due to the elongation of filiform papillae.  These papillae have a mechanical abrasive function.  These papillae do not contain taste buds   this condition can be caused by poor oral hygiene, chronic oral irritation or smoking.
The far right picture shows a patient who was a heavy smoker and has been treated with radiation therapy for head and neck cancer.  Radiation therapy causes a dry mouth with chronic oral inflammation.
Treatment involves good oral hygiene, brushing of the tongue, mouth rinses and sometimes the trimming of the elongated papilla.   The picture to the left is the same patient two months later after improvement in his oral hygiene.

  1. Black Hairy Tongue

This patient has a black hairy tongue which was caused, at least in part, by significant gastroesophageal reflux.  Control of her reflux along with the use of a topical anti-fungal medication (Nystatin), cessation of smoking and bushing of her tongue resulted in marked improvement.  The pre-treatment picture is the picture on the far right.

  1. Leukoplakia

It is a white patch which can occur in the oral cavity.  It is often caused by chronic irritation or infection but can also be a cancerous or precancerous lesion.  In this patient the leukoplakia had areas of redness called erythroplakia.   Erythroplakia often represents a cancer.
On biopsy, the patient was found to have a fungal infection.  Fungal infections of the oral cavity may often mimic a cancer both on gross appearance and sometimes even histologically.

  1. Apthosis Ulcers

Apthosis ulcers are shallow small painful ulcers which appear on mobile mucosa in the oral cavity.  They are often found in individuals that are under stress.  The cause of these ulcers is unknown.

  1. Shingles

They are caused by the Herpes Zoster Virus.  They occur many years after an individual has had chicken pox.  Once a patient has had chicken pox, they will carry the virus for the rest of their life.
When the patient does not have symptoms, the virus is in dormant state residing cell bodies of nerve tissue.  Over the years, a patient’s antibody levels fall and the dormant virus emerges.  The virus causes lesions to erupt on the skin in the regions that are innervated by the infected nerve.

Blister on Side of Tongue

They are:

  1. Stomatitis

This patient was treated with Famvir (Famciclovir) and had rapid resolution of the lesions.  The probable cause of these lesions was herpes simplex.

  1. Methicillin-resistant Staphylococcus aureus

The area was fluctuant and when lanced abundant puss was expressed.  Culture revealed MRSA.  The wound was drained and the patient was treated with Bactrum, a sulfa based antibiotic.   MRSA is in the group of bacteria referred to as Multi-Resistant Drug Organisms (MDROs).

  1. Candidiasis

It is ocaused by inhalation steroids such patients had asthma and used inhaled steroids on a daily basis.  These patients were treated with a topical anti-fungal medication, oral Nystatin.

  1. Acute Tonsillitis

This is a common condition which is usually caused by gram positive bacteria.  If the organism is Streptococcal Pyrogenesis, there is a risk of developing Rheumatic Fever.

  1. Lip Cancer

Cancer of the lip is a relatively common condition.  When caught early, it is treatable with surgery or radiation therapy.  Cancers of the lower lip have a better prognosis than those of the upper lip.  Chronic sun exposure is the most common cause, but smoking can also be an etiology.

Blisters on Back of Tongue

Causes are:

  1. Natural Blisters

The papillae that contain the taste buds on the tongue form in a V that leads to the back of the throat. You also have lingual tonsils or a round mass of lymphatic tissue at the back of the tongue that will look like a blister.
These blisters are always at the back of the tongue, but different conditions may change their appearance. Sinus infections are known to enlarge the papillae. Some people simply have taste buds that are naturally large. Sometimes eating spicy foods can inflame the taste buds as well.

  1. Trauma

If you burn your tongue it can cause blisters to appear, but this is more likely to occur at the front of the tongue rather than the back. Sometimes brushing too hard with your toothbrush can cause the tongue to become irritated and blisters to appear.
In most cases applying a saltwater or antiseptic mouth rinse will help the blisters heal. If you leave the blisters alone they will usually heal on their own. Your doctor can also prescribe you a medication that will clear up the bumps if they are stemming from another infection.

  1. Allergies

Allergies, particularly those to medications or food, can cause bumps to appear on any part of the tongue. These blisters will usually be larger toward the back of the tongue. Blisters caused by an allergic reaction will typically appear within a few minutes of coming into contact with the substance that caused the irritation.

  1. Warts

Warts typically appear in different areas of the oral cavity but they can occasionally appear on the tongue. Warts will either be a common infection that is caused by placing an infected finger in the mouth or genital warts that have been contracted by performing oral sex on someone with the infection.
Warts in the mouth will typically appear in clusters or as a singular growth. They will be a raised bump that has a wrinkled, smooth or spiky appearance. They may have a slight discoloration compared to nearby tissue which takes on a red, pink or whitish color. Warts should not be painful.

  1. Cancer

Oral blisters that are painless are rarely malignant, but any bump on the tongue runs the risk of being cancerous.
Blisters caused by cancer will typically be reddish or white and will be very easy to bleed. You may also notice ear pain, recurrent sore throats, and numbness in the area or bad breath.

  1. Canker Sores

They are painful, white lesions found on the tongue or the inside of the lips. These types of sores can be triggered from poor nutritional intake or soft tissue injury, such as with biting your tongue. Also called aphthous ulcers, they are often irritated with certain foods, including those that are spicy or very hot.

  1. Lie bumps

These little white or red blisters form when papillae become irritated and slightly swollen. It’s not always clear why this happens, but it may be related to stress, hormones, or particular foods.

  1. Lymphoepithelial Cysts

These soft yellow cysts usually appear underneath the tongue. Their cause isn’t clear. The cysts are benign and can be surgically removed.

  • Sores on the outer edge of the lips that are red or purple can be caused by the herpes simplex virus and can be passed onto baby through something as innocent as an infected relative’s gentle kiss.
  • Tooth trauma, on the other hand, refers to a broken or chipped tooth that causes openings in the tooth enamel where bacterial infection takes place.
