Tacrolimus 0.03% ointment treatment in exfoliative cheilitis: A randomised controlled clinical trial and monitoring blood concentration

Chronic nonspecific cheilitis associated with tislelizumab treatment in a patient with a history of tongue squamous cell carcinoma: a case report

BACKGROUND

Chronic nonspecific cheilitis is a complex condition characterized by persistent lip peeling and discomfort. This case report explores the clinical progression of a patient with history of tongue squamous cell carcinoma and subsequent Tislelizumab treatment, presenting with persistent lip peeling.

CASE PRESENTATION

A patient with a history of tongue squamous cell carcinoma (T2N0M0), treated with chemotherapy, surgery, and Tislelizumab, presented with six months of persistent lip peeling. Clinical examination revealed distinct features of chronic nonspecific cheilitis with infectious angular cheilitis (Oral Candidiasis). A tailored treatment plan, emphasizing oral hygiene practices and local treatments with Sodium Bicarbonate, Tacrolimus ointment, and Chlortetracycline ointment. Follow-up visits demonstrated sustained improvement, highlighting the significance of individualized approaches.

CONCLUSIONS

This case underscores the importance of recognizing and managing oral manifestations in patients with a history of cancer and immunotherapy. The patient's response to treatment suggests that a multifaceted approach, combining local therapy with lifestyle modifications, can be effective in managing chronic nonspecific cheilitis associated with immunotherapy. Routine follow-up appointments, guided by personalized medicine principles, contribute to sustained patient well-being.

Histopathologic findings in ointment pseudo-cheilitis: An alert to dermatopathologists

Ointment pseudo-cheilitis is a recently recognized distinctive type of self-induced cheilitis. Lesions consist of a variable amount of crusts adhered to the vermilion. These crusts consist of dried saliva and dead cells mixed with applied medications attached to the lip surface. Patients are typically severely anxious or depressed; the condition impacts quality of life. Ointment pseudo-cheilitis is frequently misdiagnosed as exfoliative cheilitis or cheilitis glandularis. Biopsy reports are often non-revealing because there are no established histopathological criteria for this disease, and clinicians usually do not formulate the correct diagnostic hypothesis. Here, we present the histopathological findings of four cases of ointment pseudo-cheilitis. The most consistent finding was the presence of laminated parakeratotic material detached from the epithelium in biopsies that are devoid of other significant diagnostic changes. This material at the lip surface possibly represents physiologic labial desquamation mixed with dried saliva and applied medication. With this report, we intend to alert dermatopathologists to the diagnosis of ointment pseudo-cheilitis if they receive biopsies from patients who present clinically exuberant labial lesions that show only minimal histopathological changes.

Predisposition of hypersensitivity in patients with exfoliative cheilitis

Background/purpose

Exfoliative cheilitis (EC) is a chronic and reversible inflammatory disease of the lips without definite etiology. Clinically, different types of allergens can be found in exfoliative cheilitis patients, however, few studies have focused on the relationship between exfoliative cheilitis and hypersensitivity. This research aimed to investigate the prevalence of hypersensitivity in EC patients.

Materials and methods

A prospective study was conducted in 30 patients with exfoliative cheilitis and 30 healthy controls, matched in age and sex. Laboratory tests included serum total IgE, allergen-specific IgE, and food-specific IgG.

Results

Increased serum total IgE level, positive food-specific IgG were seen more frequently in exfoliative cheilitis patients than in healthy control (P < 0.05). Special IgE level to FX5 and the degree of food-specific IgG to wheat were seen higher in exfoliative cheilitis patients than in healthy control (P < 0.05).

Conclusion

This study suggests that patients with exfoliative cheilitis may have predisposition of hypersensitivity. The detection of allergens should be strengthened in the future clinical work.
