Cutaneous mastocytosis
Urticaria pigmentosa
Get Update
Overview
Cutaneous mastocytosis is a condition caused by the accumulation of mast cells in the skin. Mast cells contain substances such as histamine that regulate allergic reactions. This condition is usually diagnosed in children and typically resolves by puberty. Treatment is generally based on a person's symptoms, but it may include antihistamines to prevent the effect of mast cell histamine.
There are several different types of cutaneous mastocytosis. Urticaria pigmentosa is the most common form and is characterized by brown patches on the skin where mast cells have accumulated. Diffuse cutaneous mastocytosis is a very rare form of the condition that presents at birth with skin that is thickened and easily blistered. A mastocytoma is raised nodule that is also usually seen in infancy. Another rare form that occurs in adults is called telangiectasia macularis eruptiva perstans (TMEP).
