Grudkowa fragmentacja włókien elastyny

A rare, acquired, dermis elastic tissue disorder characterized by multiple, asymptomatic, firm, well-demarcated, nonfollicular, hypopigmented or skin-colored papules, with a diameter of less than 1 cm, distributed symmetrically over trunk and/or proximal limbs (rarely, head, neck, shoulders, armpits, thighs), with no extracutaneous manifestations. Histopathology typically reveals decreased and fragmented elastic fibers, thickened and/or homogenized collagen bundles and, in some, a mild, perivascular, lymphocytic infiltrate in the dermis.
