Summary
Axillary dermatitis can stem from mercury salt allergies, not just cosmetics. A patient developed sensitivity to phenylmercuric borate from disinfected thermometers, confirmed by patch tests.
Area of Science:
- Dermatology
- Toxicology
- Allergology
Background:
- Axillary dermatitis is commonly attributed to cosmetic allergies, such as deodorants or antiperspirants.
- Differential diagnosis is crucial for effective treatment of skin conditions.
Observation:
- A 24-year-old male presented with acute contact dermatitis in his left axilla.
- The patient underwent pre-operative check-ups involving regular temperature measurements in the axilla using thermometers.
Findings:
- The dermatitis was linked to sensitization against mercury salts, specifically phenylmercuric borate.
- Phenylmercuric borate was used in a disinfecting solution for thermometers in two separate hospital settings.
- Positive patch tests confirmed the patient's sensitivity to mercury salts.
Implications:
- This case highlights a non-cosmetic cause of axillary dermatitis.
- Awareness of environmental and medical product exposures is vital for diagnosing contact dermatitis.
- Healthcare providers should consider less common allergens in differential diagnoses for axillary rashes.
