title: Primary localized cutaneous amyloidosis in association with papillary thyroid carcinoma.
abstract: BACKGROUND
  Lichen amyloidosis, a type of primary localized cutaneous amyloidosis, is characterized by pruritic brown or grayish pigmented papules.
  
  
  OBJECTIVE
  We report a case of lichen amyloidosis in which the skin lesion consisted of asymptomatic salmon-pink-colored papules on the back of the neck to the upper back. This was different from typical clinical pictures of lichen amyloidosis. Our patient proved to have thyroid papillary carcinoma.
  
  
  CONCLUSIONS
  Our case may suggest that lichen amyloidosis could be a cutaneous manifestation of thyroid cancers.
