Summary
A patient experienced a severe allergic reaction, later identified as a mango allergy, after initial treatments failed. Avoiding mangoes resolved the eruption, highlighting the importance of thorough allergy testing for persistent skin conditions.
Area of Science:
- Dermatology
- Allergology
- Contact Dermatitis
Background:
- A 22-year-old female presented with a widespread pruritic rash and periorbital edema.
- Previous similar episodes were treated with antihistamines and topical steroids without full resolution.
Observation:
- The patient reported frequent mango consumption and denied new contact allergens.
- Physical examination revealed facial erythema, papules on the face and extremities, and a wrist plaque.
Findings:
- Patch testing revealed positive reactions to nickel, p-tertbutylphenol formaldehyde resin, and bullous reactions to mango skin and flesh.
- Complete avoidance of mango resulted in the resolution of the eruption.
Implications:
- Mango ingestion can cause severe allergic contact dermatitis, mimicking other conditions.
- Thorough patch testing is crucial for diagnosing persistent or recurrent allergic eruptions of uncertain etiology.
- Identifying and avoiding specific allergens, like mangoes, is key to managing allergic skin reactions.
