Apolipoprotein E4 is associated with primary localized cutaneous amyloidosis.
Apolipoprotein E (apoE) is a lipid transport protein, which is a component of lipoproteins, such as very low density lipoprotein, intermediate density lipoprotein, high density lipoprotein, and chylomicron. ApoE is also produced and secreted in the skin, and is implicated to play roles in epidermal differentiation and proliferation (Barra et al, 1994). We have reported that apoE was a component...

BACKGROUND Macular and lichen amyloidosis are clinical variants of primary localized cutaneous amyloidosis (PLCA). Most cases are sporadic, but approximately 10% of cases may be familial. To our knowledge, the clinicopathologic and molecular features of such pedigrees, however, have not been studied in detail. OBSERVATIONS We assessed 2 Brazilian families with either lichen-type (family 1 had...
متن کامل[Disseminated nodular primary localized cutaneous amyloidosis].
Amyloid is a proteinaceous material that is deposited in the tissues in a large variety of clinical contexts; in the skin it can be found with or without concomitant systemic disease. Primary localized cutaneous amyloidosis encompasses those amyloidoses restricted to the skin without involvement of other systems. The most common forms within this group are macular and lichen amyloidosis. Nodula...
متن کامل[Localized primary cutaneous nodular amyloidosis in a patient with paraproteinemia].
The term primary cutaneous amyloidosis (PCA) refers to a group of diseases caused by the extracellular deposition of amyloid in the skin without the involvement of other organs. PCA has been divided into the following types: macular, lichen and nodular. The first 2 types are characterized by the deposition in the papillary dermis of amyloid derived from the degeneration of keratin filaments. Pr...
متن کاملPrimary localized cutaneous amyloidosis in patients with scleroderma.
Primary localized cutaneous amyloidosis (PLCA) is a relatively rare condition characterized by amyloid de-position exclusively in the dermis without involving the internal organs. Clinically, papular, macular and tumefac-tive forms are presented. Although PLCA may sometimes overlap with collagen vascular diseases, association with scleroderma is rare. We report here two cases of PLCA developing...
