Cheilitis Exfoliativa
• Desquamative, mildly inflammatory, recurrent
condition of the lips. Fissures if severe.
• Etiology:
– upper lip: cause is often unknown. Primary disorder.
– lower lip: It is a reaction to other disease states, ie SD,
AD, PV, Plummer-Vinson syndrome.
– Irritation: lipsticks, dentrifices, mouthwashes,
shaving/aftershave, nail enamel, lip licking, UV
• Tx: Remove cause, topical steroids, ointments.
Allergic Contact Cheilitis
• Vermillion border is most common with
dryness, fissuring, edema, crusting, angular
cheilitis.
• Etiology:
– Topicals - meds, dental, lipsticks, sunscreen lip
balms, cosmetics, nail polish, cigarette holders,
rubber, metals, toothpaste.
– Foods – oranges, lemons, artichokes, mangoes
– Saxophone or Clarinet cane reeds
• Tx: avoid antigen, topical steroids

Toothpaste
Actinic Cheilitis
•
•
•
•
Lower lip, UV induced.
Ulceration is rare unless SCC is present
Hereditary PMLE may mimic.
Treatment:
– Biopsy if thickened or ulcerated.
– Cyro, 5-FU, CO2 laser, Vermilionectomy,
Photodynamic Therapy with 5-ALA, H&E
same as AK.
Cheilitis Glandularis
• Presentation: Swelling and eversion of lower lip
with patulous openings of the ducts of the mucous
glands - Chronic, inflammatory.
• Mucous exudes freely to form a glue-like film,
lips stick together. Palpation - feels like pebbles
beneath the surface.
• Apostematosa variant has abscess formation.
• Etiology: irritation, atopic, factitious, actinic.

the presence of any 2 of the following:
1. Recurrent genital ulceration
2. Retinal vasculitis, Ant./Post. Uveitis
3. EN, Folliculitis, Papulopustular, Acneiform
4. Positive pathergy test.
Behcet’s Disease
• Oral:
– Ulcers are 2-10mm, sharply circumscribed, with a dirty
grayish base and a surrounding bright red halo.
• Genital lesions:
– Similar to oral lesions. Appear on genitals, perineum, anus
or rectum.
• Ocular lesions:
– Start with intense periorbital pain and photophobia,
conjunctivitis. Retinal vasculitis may lead to blindness.
Also glaucoma and cataracts.
• CNS:
– Multiple sclerosis-like.
• GI symptoms: due to intestinal ulcerations.
• Others: thrombophlebitis, vasculitis,Polyarthralgia
Behcet’s Disease
• Course: Starts with oral ulcerations and
over time (often years) others symptoms
develop.
• Incidence: Relatively high prev in Far East
and Mediterranean. Less common in U.S.
• Pathology: LCV
Pathergy test – Inject 0.1 ml of NS or just prick the skin. Pustule forms
24 hours after needle-stick.
Helpful for diagnosis, but usually negative even in the presence of
Behcets’ Syndrome
HISTOLOGY OF BEHCET’S: LCV - A neutrophilic
infiltrate surrounds the superficial capillary plexus in the
papillary dermis, with destruction of small vennules. There
is fibrin deposition in the blood vessel walls, transmural
migration of PMNs, extravasated RBCs and nuclear dust
FIBRIN

IgM
Behcet’s
Disease
Behcet’s Treatment
Treatment of ulcers:
•
•
Ulcerations usually heal spontaneously
Oral hygiene – mild toothpastes, limited
toothbrushing.
Prevention of attacks:
•
•
•
•
•
Sucralfate suspension
Colchicine 0.6mg bid
Dapsone 100mg daily
Thalidomide 200mg bid x 5 days then 100mg bid
x 15-60 days
