Although cheilitis as a term describing lip inflammation has been identified and recognized for a long time, until now there have been no clear recommendations for its work-up and classification. The disease may appear as an isolated condition or as part of certain systemic diseases/conditions (such as anemia due to vitamin B12 or iron deficiency) or local infections (e.g., herpes and oral candidiasis). Cheilitis can also be a symptom of a contact reaction to an irritant or allergen, or may be provoked by sun exposure (actinic cheilitis) or drug intake, especially retinoids. Generally, the forms most commonly reported in the literature are angular, contact (allergic and irritant), actinic, glandular, granulomatous, exfoliative and plasma cell cheilitis. However, variable nomenclature is used and subtypes are grouped and named differently. According to our experience and clinical practice, we suggest classification based on primary differences in the duration and etiology of individual groups of cheilitis, as follows: 1) mainly reversible (simplex, angular/infective, contact/eczematous, exfoliative, drug-related); 2) mainly irreversible (actinic, granulomatous, glandular, plasma cell); and 3) cheilitis connected to dermatoses and systemic diseases (lupus, lichen planus, pemphi-gus/pemphigoid group, -angioedema, xerostomia, etc.).

Oral allergies to dental materials are a growing problem and remain poorly diagnosed by health professionals. The complaints of patients with oral allergy are various and include sensations of burning or stinging of the oral mucosa, sensations of dryness of the oral cavity, or general symptoms such as headache, dyspepsia, asthenia, arthralgia, and myalgia. Signs suggestive of oral allergy include erythema, edema, purpuric patches on the palate, ulcerations of the oral mucosa (canker sore), gingivitis, glossitis mimicking geographic tongue, angular cheilitis, peri-oral eczema or the presence of lichenoid reactions of the oral mucosa. The diagnosis of an allergy will include data from the anamnesis, the clinical examination, as well as the results of allergy tests: epicutaneous tests (patch tests) or cutaneous tests (prick tests), possibly completed by a blood test ( in vitro lymphoblastic transformation test ou LTT).

An immediate, successful result - pain and symptom free one year later.

The nonpathogenic species Siccibacter turicensis is closely related to members of the food-associated pathogenic genus Cronobacter and has been detected in fruit powders, formula, spices, and herbs. Here, we report on the first clinical isolate of S. turicensis, recovered from the labial angle of a patient with angular cheilitis.
