Abstract

A 42-year-old woman presented with a hypersensitivity reaction after the ingestion of a small amount of fresh mango gelato. She developed itchy palpable purpuric lesions over her arms, legs, neck and abdomen 4 days after ingestion. The lesions persisted for 5 weeks despite treatment with betamethasone-17 valerate 0.05% ointment and avoidance of mango. Resolution of these lesions was eventually achieved with continuing treatment. The patient denied any prior contact with mango skin but had experienced previous sensitizing reactions to mango flesh. Patch testing was strongly positive to mango skin and mango flesh. Skin-prick testing was negative. This case describes a systemic contact dermatitis to mango flesh, an entity less common than allergic contact dermatitis.

Allergy and Asthma

Allergy and asthma are inflammatory disorders that are triggered by the activation of an allergen-specific regulatory t cell. These t cells become activated when allergens are recognized by allergen-presenting cells. Here is the latest research on allergy and asthma.
