Cutaneous mastocytosis (CM) most commonly affect children, which is usually diagnosed prior to 2 years old with slight male predominance <ref>{{Cite journal|last=Castells|first=Mariana|last2=Metcalfe|first2=Dean D.|last3=Escribano|first3=Luis|date=2011-08-01|title=Diagnosis and treatment of cutaneous mastocytosis in children: practical recommendations|url=https://pubmed.ncbi.nlm.nih.gov/21668033|journal=American Journal of Clinical Dermatology|volume=12|issue=4|pages=259–270|doi=10.2165/11588890-000000000-00000|issn=1179-1888|pmc=4126834|pmid=21668033}}</ref><ref>{{Cite journal|last=Hartmann|first=Karin|last2=Henz|first2=Beate M.|date=2002-02|title=Cutaneous mastocytosis -- clinical heterogeneity|url=https://pubmed.ncbi.nlm.nih.gov/11919426|journal=International Archives of Allergy and Immunology|volume=127|issue=2|pages=143–146|doi=10.1159/000048187|issn=1018-2438|pmid=11919426}}</ref>.

There are three typical variants of cutaneous mastocytosis: 1) urticaria pigmentosa (UP)/maculopapular cutaneous mastocytosis (MPCM), 2) diffuse CM, and 3) mastocytoma of skin.  UP/MPCM is the most common type and presents as brown or red macule or macule and papules with melanin pigmentation. Diffuse CM is almost exclusively in childhood and presents as diffusely thickened skin, pachydermia. Familial cases and germline mutations can be associated diffuse CM. Cutaneous mastocytoma is also known as solitary mastocytoma of skin, which is single or less than 3 lesions without predilection for presenting site. In addition, CM cannot be diagnosed if the features or criteria of systemic mastocytosis are met.

==Sites of Involvement==
Cutaneous mastocytosis can present in any location of the body with common involvement of extremities and trunk.
==Morphologic Features==
Histologically, CM demonstrates increased number of mast cells in skin lesion. UP/MPCM reveals spindle-shaped mast cells in papillary dermis with extension to reticular dermis. Diffuse CM demonstrate highest number of mast cells in sheets filling papillary and upper reticular dermis. Cutaneous mastocytoma usually involves subcutaneous tissue with abundant granular cytoplasm of mast cells.
