Amyloidosis cutis dyschromica (ACD) is a rare form of macular amyloidosis characterized by hypo and hyperpigmented macules. Here we described a 20 year old girl with diffuse hypo and hyperpigmentation since she was four years old. Five other members of her family are also involved. Biopsy of hyperpigmented lesions revealed increase of melanin in the basal layer, pigment incontinence and amorpho...

Primary cutaneous amyloidoses (PCA) are a group of conditions characterized by deposition amyloid in previously normal skin, without association with other skin or systemic diseases. We describe Kazakhstani female 30-year history increasingly spreading hyperpigmented macular as well papular lesions on her upper trunk accompanied pruritus. Moreover, medical included intensely rubbing cotton towe...

Introduction: Macular amyloidosis is a relatively rare disease. A basic change appears to be amyloid material deposition in an apparently normal skin. The characteristic features of the disease are reticulate and ripple brown pigmentation in interscapular regions. Shoulder, back and chest. There are several reports indicating the association of the disease with rubbing against the skin. Accordi...

BACKGROUND Primary localized cutaneous amyloidosis (PCA) is a relatively rare condition characterized by amyloid deposition in dermis without systemic involvement. Although, histopathological examination of the lesion reveals amorphous eosinophilic deposits in papillary dermis examination of congo red stained slides under polarized light will give definitive diagnosis AIMS To study the clinic...

Amyloidosis is induced by deposition of amyloid proteins in various organs. Both systemic and localized type amyloidosis present with a variety of skin manifestations. Based on biochemical and immunological aspects, amyloid proteins are subdivided into several subtypes from different origins. Amyloid fibrils in primary and multiple myelomaassociated systemic amyloidosis are composed of immunogl...

We report a 51-year-old Vietnam War veteran with an unusual variant of macular amyloidosis presenting as poikilodermatous skin lesions. The extensive mottled brown pigmentation was checkered with small hypopigmented or normal skin-colored spots and intermingled with telangiectasia. Skin biopsy revealed subepidermal amyloid deposits. There was no evidence of extracutaneous involvements. This cas...
