EAH and the clinical differential diagnoses of EAH, including the features of demography and histopathological findings.

Disease	Number of Cases Reported in English	Histopathological Finding	Reference
EAH	<100	the lesion affects mainly mid and deep dermis and is composed of lobules of proliferating capillaries intricately admixed with sweat glands and ducts, fat and myxoid tissue.	[12]
Eccrine nevus	20	It is characterized by groupings of normal to enlarged eccrine structures. (The absence of angiomatous hyperplasia)	[13]
Tufted angioma	200	multiple, scattered lobules of small capillary type vessels with small oval to spindle shaped cells throughout the dermis and subcutaneous tissue imparting a “cannonball” or glomerular appearance.	[14]
Smooth muscle hamartoma	<20 (Only acquired type)	It shows disseminated proliferation of mature smooth muscle cells of a central cigar-shaped nucleus and fibrillary and eosinophilic cytoplasm.	[15,16]
Blue rubber bleb nevus syndrome	200	cutaneous lesions are non-specific and have features of venous malformations. Large, tortuous, dilated vessels with a single endothelial lining are noted, and smooth muscle may be present in the vessel walls.	[17]
