Apocrine naevus:  Pure apocrine nevus is a rare tumour. 

Site: Upper chest and axilla. 

Microscopic features:  Consists of numerous apocrine glands extending from the reticular layer of the dermis to the subcutaneous tissue.

The term 'eccrine hamartomas' is used to include a wide range of nevoid condition involving the eccrine sweat glands.

Eccrine naevus:  These are rare benign lesions characterised by an increase in number and size of normal appearing eccrine coils.

Eccrine angiomatous hamartoma:  There is an increase in eccrine glands together with small blood vessels, nerve fibres, mucin or fat.  Clinical presentation:  Gradually enlarging painful papule or nodule that may show hyperhidrosis.  Gross:   Usually solitary flesh-colored or bluish-purple,  painful papule or plaque appearing at birth or during childhood. Site:  Usually located on the extremities.

Porokeratotic eccrine ostial nevus: There are cornoid lamellae associated with eccrine ducts.
