A rare group of mastocytosis diseases characterized by abnormal accumulation and proliferation of mast cells in the skin and including the three recognised forms: diffuse cutaneous mastocytosis, cutaneous mastocytoma and, the most common form, maculopapular cutaneous mastocytosis. In some cases (most commonly in adults), cutaneous mastocytosis may occur in association with mast cell infiltration of various extracutaneous organs, in which case the disorder is referred to as systemic mastocytosis.
