Abstract: A 20-year-old man presented with recurrent cheilitis
HPI: A 20-year-old student presented with recurrent peeling of
the lips for about 3 years. It usually began on the upper lip then involved the
lower lip. Then the cycle repeated. The entire process takes about 3 weeks. He
has no known drug allergy. He denied any lip smacking. He was using a
moisturising non-SLS tooth paste.
Examination showed peeling of the lower and upper lip as a
single friable sheet. His oral cavity and genitalia were unremarkable.
Clinical Images:
Patch Tests:
Iodopropynyl butylcarbamate
+ at 48 and – at 96 hours
Sodium bisulphide + at 48 and 96 hours
Thimerosal +/- at 48 and 96 hours
Histopathology: The sections show a fragment of tissue
surfaced by parakeratinised stratified squamous epithelium. The underlying
connective tissue is moderately collagenous with mild chronic inflammatory
cells infiltration and a few small blood vessels. A few lobules of minor
salivary glands are observed. No granuloma seen in the sections examined. Final Path Diagnosis: Lower labial mucosa: Histologically non-specific
Diagnosis: Chronic cheilitis
Reason for presentation
Despite avoiding all the trigger factors such as lip
smacking and use of non-SLS toothpaste, his symptoms persisted. The patch test
results are probably irrelevant in his case. In a study from Singapore,
toothpastes were the commonest cause of allergic contact cheilitis in males.
Ricinoleic acid and the patient's own lip preparations were the commonest
relevant contact allergens. The absence of granuloma practically make
granulomatous cheilitis unlikely.
Questions
What is the most likely diagnosis? Could this be a case of
exfoliative cheilitis? Exfoliative cheilitis, a rare, localized condition, is a
chronic superficial inflammatory condition that is characterized by regular
peeling of a superficial excessive layer of keratin. the cause of this
condition is unknown but may be associated with depressive illness. Two other differential
diagnosis comes to mind - pemphigus vulgaris and Crohn's disease.
