	*Diagnosis:*	LICHEN AMYLOIDOSIS	*Category:*	deposition disorders / papulosquamous eruptions
	*Body Site:*	shin	*Age:*	25 years
	*Contributor:*	Greg Hosler, MD, PhD
	*Description:*	The epidermis is acanthotic and papillomatous. There is hypergranulosis and orthokeratotic hyperkeratosis. Eosinophilic amorphous material collects in the dermal papillae.
	*Comments:*	This biopsy from a 25 year old woman was submitted to rule out hypertrophic lichen planus. She had hyperkeratotic and almost verrucous plaques on her shins. They were pruritic. This biopsy has a low power look of lichen simplex chronicus, which is a typical finding in lichen amyloidosis. The amyloid collects in the dermal papillae and consists of keratins. It is likely related to LSC as both are associated with chronic rubbing.
