Perianal contact dermatitis caused by nail lacquer allergy
1Dermatology Clinic, Sapir Medical Center, Meir Hospital, Kfar Saba, Israel.
Summary
Allergic contact dermatitis from nail lacquer can occur in unusual locations, such as the perianal area. This case highlights the importance of considering distant sites when diagnosing nail cosmetic allergies.
Area of Science:
- Dermatology
- Allergology
- Cosmetic Science
Background:
- Allergic contact dermatitis (ACD) to nail cosmetics is less common than to other cosmetic products.
- Typical ACD presentations involve the face, neck, hands, and areas around the nails.
Observation:
- A patient presented with pruritus and dermatitis in the perianal and eyelid regions.
- The patient's symptoms were suspected to be related to nail lacquer use.
Findings:
- Patch testing revealed a positive allergic response to toluenesulfonamide-formaldehyde resin.
- The patient's personal nail lacquers also triggered a positive allergic reaction.
Implications:
- Nail lacquer allergy can manifest in distant body sites, not just direct contact areas.
- The perianal region may be an underrecognized site for nail lacquer-induced ACD.
- Clinicians should consider nail cosmetics as a potential allergen for dermatitis in atypical locations.
