Occupational skin diseases is one of the top occupational diseases, and the most common form is contact dermatitis accounting for 90%. In healthcare workers, allergens most commonly identified are preservatives, excipients in cleansers, antiseptics and rubber accelerators. Contact dermatitis has a major impact in performance at the workplace and overall quality of life. Allergen avoidance is the cornerstone of management of contact dermatitis, and this poses a challenge to those exposed in the workplace.

A 31-year-old female nurse, with no known comorbidities, presented with several-years history of on-off episodes of pruritic, scaly plaques on the hands that would occasionally have fissures with associated 8/10 pain. She sought consult with several physicians, diagnosed as non-specific eczema, and was prescribed topical steroids and antihistamines with partial improvement. Due to the recurrence of the lesions, an 83-allergen patch test was done. There was a +2 reaction to carba mix noted as erythematous, indurated papules and plaque with pinpoint crusts. A definite relevance was identified since the patient works as a nurse with regular use of rubber gloves. The patient was diagnosed with allergic contact dermatitis, and advised measures to avoid exposure to the allergen.

Carba mix contains diphenylguanidine, zinc dibutyldithiocarbamate and zinc diethyldithiocarbamate, and can be found in rubber products such as gloves. Healthcare workers, especially nurses, are constantly exposed to this allergen since gloves are part of the standard and basic personal protective equipment. This case outlines the impact of patients’ occupation to their overall health.
