Maculopapular cutaneous mastocytosis

What causes maculopapular cutaneous mastocytosis?

Maculopapular cutaneous mastocytosis occurs when there are too many inflammatory cells (called mast cells) in the skin. The underlying reason for this excess of mast cells is not fully understood. While most cases appear to be random (occur sporadically for no apparent reason), familial cases have been reported. These familial cases are thought to be inherited in an autosomal dominant manner and may be caused by mutations in the KIT gene.

How might maculopapular cutaneous mastocytosis be treated?

Maculopapular cutaneous mastocytosis is generally not serious and many cases do not require treatment. For those cases that do, oral antihistamines, topical steroids, and a photochemotherapy called PUVA may be used. These treatments are aimed at reducing the symptoms of the condition and making patients more comfortable.
