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
Allergic Contact Cheilitis
Toothpaste
Actinic Cheilitis
• Lower lip, UV induced.
• Ulceration is rare unless SCC is present • Hereditary PMLE may mimic.

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.
Cheilitis Glandularis “STICKY LIPS” TX SAME AS ACTINIC CHEILITIS
Cheilitis Glandularis
H&E – infiltration of lymphocytes, histiocytes and plasma cells in and around the ectatic glands.
Angular Cheilitis (Perleche)

Recurrent Aphthous Stomatitis
Approach to Recurrent Apthous Stomatitis
• GI symptoms or surgeries ? – UC, Crohn’s, Celiac Dz, Malabsorption (B1, B2, B6) • Genital or Ocular lesions? – Behcet’s, or Reiter’s syndromes. • Evaluate risk factors for HIV, AIDS.
• Laboratory: – CBC for anemia, B-12, Folate, Iron, Neutropenia.
– Tzanck to R/O Herpes, RPR to R/O syphillis – Biopsy to rule out pemphigus, LP
Recurrent Aphthous Stomatitis Treatment

• Numerous small vesicles in clusters • Rupture abruptly to form punctate erosions with a red base.
• Tzanck smear shows multinucleated epithelial cells.
• Palate is most common. (Pearl: Herpangina and Apthous ulcers occur on non-attached mucosa, whereas recurrent Herpes simplex occurs on mucosa fixed to bone)
Periadenitis Mucosa Necrotica Recurrens (Major Aphthous Ulcer)
• Sutton’s Dz • Sharply circumscribed ulcer with deeply punched out and depressed crater • Heals with scar.
• Freq.assoc with HIV.
• Tx: IL steroids. If frequent then colchicine or dapsone.
Behcet’s Syndrome
(Oculo-Oral-Genital Syndrome)
Oral ulcers that recur at least 3 times per year in 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
Behcet’s Disease
C-3 IgM
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 Methotrexate for severe refractory cases
