Summaries for Amyloidosis, Primary Localized Cutaneous, 1

UniProtKB/Swiss-Prot : 75 Amyloidosis, primary localized cutaneous, 1: A primary amyloidosis characterized by localized cutaneous amyloid deposition. This condition usually presents with itching (especially on the lower legs) and visible changes of skin hyperpigmentation and thickening that may be exacerbated by chronic scratching and rubbing. Primary localized cutaneous amyloidosis is often divided into macular and lichen subtypes although many affected individuals often show both variants coexisting. Lichen amyloidosis characteristically presents as a pruritic eruption of grouped hyperkeratotic papules with a predilection for the shins, calves, ankles and dorsa of feet and thighs. Papules may coalesce to form hyperkeratotic plaques that can resemble lichen planus, lichen simplex or nodular prurigo. Macular amyloidosis is characterized by small pigmented macules that may merge to produce macular hyperpigmentation, sometimes with a reticulate or rippled pattern. In macular and lichen amyloidosis, amyloid is deposited in the papillary dermis in association with grouped colloid bodies, thought to represent degenerate basal keratinocytes. The amyloid deposits probably reflect a combination of degenerate keratin filaments, serum amyloid P component, and deposition of immunoglobulins.

MalaCards based summary : Amyloidosis, Primary Localized Cutaneous, 1, also known as primary localized cutaneous amyloidosis 1, is related to posterior cortical atrophy and pigmentary disorder, reticulate, with systemic manifestations, x-linked. An important gene associated with Amyloidosis, Primary Localized Cutaneous, 1 is OSMR (Oncostatin M Receptor). The drugs Flurbiprofen and Nalbuphine have been mentioned in the context of this disorder. Affiliated tissues include skin, and related phenotypes are cutis laxa and pruritus

OMIM : 57 Primary localized cutaneous amyloidosis is characterized clinically by pruritus and skin scratching and histologically by the finding of deposits of amyloid staining on keratinous debris in the papillary dermis (summary by Tanaka et al., 2009). (105250)
