Familial primary localized cutaneous amyloidosis
Synonyms: FPLCA
A rare primary cutaneous amyloidosis characterized by familial occurrence of lichen and/or macular amyloidosis due to fibrillary degeneration and apoptosis of basal keratinocytes followed by conversion of filamentous masses into amyloid material in the papillary dermis. Patients typically present with a pruritic eruption of grouped hyperkeratotic papules which may coalesce to form hyperkeratotic plaques with a predilection for the lower limbs (lichen amyloidosis) or with hyperpigmented macules sometimes with a reticulate pattern most commonly arising on the back chest or interscapular areas (macular amyloidosis).
