Primary cutaneous amyloidosis

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
  • Histopathology of lichen amyloidosis, with subepithelial Congo red-positive deposits
  • Nodular amyloidosis is a rare cutaneous condition characterized by nodules that involve the acral areas.[4]:521
