Urticaria pigmentosa was first described by Nettleship and Tay in 1869 as a rare form of urticaria.6 Unna in 1887 demonstrated the relationship between urticaria pigmentosa and mast cells.7 In cutaneous mastocytosis, histamine release from their granules led to urticarial edema of the lesions, which results in secondary hyperpigmentation due to melanocytic activity at the dermoepidermal junction.8 Mast cells were first described by Erhlich.9,10 They contain histamine granules and other inflammation mediators.
Urticaria pigmentosa has a more severe course and may lead to life-threatening conditions by causing hypovolemic shock, mast cell leukemia, gastrointestinal hemorrhage and cachexy (25).
