Primary cutaneous amyloidosis is a form of
amyloidosis associated with
oncostatin M receptor.[2][3]
This type of amyloidosis has been divided into the following types:[4]: 520
Macular amyloidosis is a cutaneous condition characterized by itchy, brown, rippled
macules usually located on the interscapular region of the back.[4]: 521 Combined cases of lichen and macular amyloidosis are termed biphasic amyloidosis, and provide support to the theory that these two variants of amyloidosis exist on the same disease spectrum.[5]
Lichen amyloidosis is a cutaneous condition characterized by the appearance of occasionally itchy lichenoid
papules, typically appearing bilaterally on the shins.[4]: 521
