Acute Allergic Contact Dermatitis of the Lips from Peppermint Oil in a Lip Balm
Bibliographic record
Abstract
The etiology of cheilitis is often not readily apparent. We present a case series of four patients with allergic contact cheilitis (ACC) secondary to exposure to peppermint oil contained in a lip balm product. These patients developed eczematous dermatitis involving their lips and perioral skin. They were tested with the North American Contact Dermatitis Group standard series as well as with an expanded series of flavoring agents, sunscreens, plant and fragrance components, and their own products. The lip balm contained potential sensitizers such as propolis, lanolin, coconut oil, almond oil, peppermint oil, and vitamin E. Our patch-test results showed that peppermint oil was the most likely culprit in these patients' ACC. Peppermint oil is less commonly reported as causing ACC than are more common contactants such as balsam of Peru or nickel sulfate. However, with the widespread use of lip balms containing peppermint oil, more cases of peppermint oil-induced ACC may be expected.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
