    Area of Science:

    • Dermatology
    • Allergology
    • Medical Device Safety

    Background:

    • Allergic contact dermatitis (ACD) is a common delayed-type hypersensitivity reaction.
    • Disposable medical devices can be sources of allergens, leading to occupational or patient-related ACD.
    • Electrosurgical devices are widely used in surgery, necessitating an understanding of their potential dermatological risks.

    Observation:

    • A 50-year-old male patient presented with symptoms of dermal allergic contact dermatitis.
    • The dermatitis developed subsequent to exposure to a disposable electrosurgical electrode.
    • Standard patch testing was performed to identify the causative agent.

    Findings:

    • Patch testing failed to identify a specific allergenic component within the disposable electrosurgical electrode.
    • The electrode's material composition did not include previously identified common contact allergens.
    • This suggests a potential novel or uncharacterized allergen associated with electrosurgical electrodes.

    Implications:

    • The findings highlight a potential risk of ACD from disposable electrosurgical electrodes, even in the absence of known allergens.
    • Further investigation is warranted to identify the specific causative agent in such electrodes.
    • This case underscores the importance of considering medical device components in the differential diagnosis of unexplained contact dermatitis.
