Predisposition of hypersensitivity in patients with exfoliative cheilitis

Cheilitis: A Diagnostic Algorithm and Review of Underlying Etiologies

Cheilitis, or inflammation of the lips, is a common reason for dermatologic consultation. The inflammation can include the vermillion lip, vermillion border, and surrounding skin, and can present with an acute or chronic course. There are many etiologies, including irritant and allergic contact dermatitis, atopic cheilitis, actinic cheilitis, infectious etiologies, nutritional deficiencies, drug-induced cheilitis, and rare etiologies, including granulomatous cheilitis, cheilitis glandularis, plasma cell cheilitis, lupus cheilitis, and exfoliative cheilitis. Distinguishing among the various etiologies of cheilitis is clinically difficult, as many causes may produce similar erythema and superficial desquamation of mucosal skin. In addition, patients report dryness, redness, irritation, burning, fissuring, and itch in many of the underlying causes. Thus, the specific etiology of cheilitis is often difficult to diagnose, requiring extensive testing and treatment trials. In this review, we summarize the various types of cheilitis, synthesizing novel cases, clinical presentations, histopathology, epidemiology, and advancements in diagnostic methods and therapeutics. We provide a diagnostic algorithm aimed to assist clinicians in the management of cheilitis.

The scientometric characteristics of cheilitis researched by multidisciplinary specialists: A comparative study

Background/purpose

Cheilitis is a relatively common lip disease with many etiologies and causes including concomitant mucocutaneous or systemic diseases, which needs multidisciplinary communication. The purpose of this study was to compare the scientometric characteristics of cheilitis publications by multidisciplinary specialists.

Materials and methods

All the papers on cheilitis were comprehensively retrieved from the Scopus database, and divided into three groups (dermatologists, stomatologists, and other scholars).

Results

There were 478 and 241 papers on cheilitis published by dermatologists and stomatologists, respectively. The total citation count was 5838 and the h index was 36 for cheilitis publications by dermatologists, and the total count was 2983 and the h index was 27 for cheilitis publications by stomatologists. Interestingly, we observed that dermatologists preferentially concerned contact cheilitis/dermatitis and plasma cell cheilitis, while stomatologists preferentially concerned cheilitis-related lip neoplasms including squamous cell carcinoma, dysplasia, and precancerous conditions. The most common disorder researched by both dermatologists and stomatologists was actinic cheilitis. The keywords such as patch test, cosmetic, edema, drug efficacy, toothpaste, lipstick, allergens, and granulomatous inflammation were common in dermatologists' publications; while the keywords such as protein expression, metabolism, risk factor, prevalence, malignant transformation, and carcinogenesis were common in stomatologists' publications.

Conclusion

This study for the first time reported the scientometric characteristics of cheilitis as an interdisciplinary disease researched by specialists. It highlights that cheilitis-related specialists through reciprocal collaboration and communication will improve the patients' outcomes.

Successful treatment of exfoliative cheilitis with dupilumab: A case report

This case report describes the first known successful treatment of exfoliative cheilitis with the interleukin-4 receptor alpha antagonist dupilumab in an adult patient. With no response to topical tacrolimus, hydrocortisone, dapsone, crisaborole or systemic doxycycline, low dose isotretinoin, or methotrexate, she had resolution with off-label dupilumab after 4 months of treatment.

Analysis of clinical presentations, lip transepidermal water loss and associated dermatological conditions in patients with chronic cheilitis

Chronic cheilitis (CC) is a spectrum of inflammatory changes of unknown etiology that affect the vermilion of the lips. This study aimed to describe the epidemiology, clinical presentations and risk factors of CC. Patients with CC were recruited from the National Clinical Research Center for Oral Disease of China. A convenience sample of inhabitants who live in the same geographical region were recruited as the control group. The lip skin transepidermal water loss (TEWL) and capacitance of CC patients were compared with that of age- and gender-matched controls. Our results demonstrated that of the 109 patients with CC, 72 (66.1%; 95% CI: 57.0-75.1%) were female. The common clinical presentations of CC consisted of desquamation (n = 99; 90.8%), and/or chapping (n = 81; 74.3%), and/or pruritus (n = 64; 58.7%). Multivariable analysis showed that allergic dermatologic diseases (P < 0.001; OR: 4.5; 95% CI: 2.4-8.4), anemia (P = 0.001; OR: 3.3; 95% CI: 1.5-7.5), and indoor/outdoor alternate working environment (P < 0.001; OR: 2.1; 95% CI: 1.5-2.8) were the significant risk factors for CC. The mean lip skin TEWL was found to be significantly higher, while the capacitance was lower in CC patients compared to that of control individuals. This study provides insights into the etiopathogenesis of CC and may help clinicians to identify the most effective management strategies.
