Cutaneous mastocytosis (CM) primarily affects the skin and is more common in children.
Subtypes:
Urticaria Pigmentosa: This is the most common form of cutaneous mastocytosis and typically appears as reddish-brown patches or small raised bumps on the skin.
Diffuse Cutaneous Mastocytosis: This form is more extensive and covers larger areas of the skin.
Telangiectasia Macularis Eruptiva Perstans (TMEP): This is characterized by reddish-brown macules or small bumps, often with telangiectasia (dilated blood vessels) on the skin.
