Hypersensitivity reaction to the ingestion of mango flesh.

Thoo CH, Freeman S

Skin and Cancer Foundation, Sydney, New South Wales, Australia.

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.
