Background:
Granular parakeratosis is a hyperkeratotic eruption of unknown etiology that occurs in the axilla and other intertriginous areas. The histologic features are unique for the retention of keratohyalin granules in the stratum corneum.
Objective:
The aim of the article is to review the clinical manifestations and treatment of granular parakeratosis.
Methods:
A case report and literature review are presented.
Results:
Twenty-six cases of granular parakeratosis now have been reported and reviewed.
Conclusion:
Granular parakeratosis occurs predominantly in middle age women and most frequently in the axilla. A number of treatments have been applied to the 26 cases reported to date, without consistent responses. No evidence-based therapy can be suggested at present.

Cells of the Epidermis
The cells in all these layers except the stratum basale are called keratinocytes, a type of cell that manufactures and stores the protein keratin. The keratinocytes in the stratum corneum are dead and regularly slough away, being replaced by cells from...
Papillary Dermis
The dermis might be considered the "core" of the integumentary system, as distinct from the epidermis and hypodermis. It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts.
Papillary Layer
The papillary layer is made of loose, areolar connective tissue, which means the collagen and...
