Extensive nodular cutaneous amyloidosis: an unusual presentation.
Amyloidosis is characterized by the deposition of a group of unrelated proteins leading to changes in tissue architecture and function. The nodular variant is the rarest form of the cutaneous amyloidoses. We report a patient with localized nodular amyloidosis without systemic amyloid involvement or paraproteinaemia after 6 years of follow-up. The unusual aspects of our case were a plaque presentation rather than nodular, and the disseminated pattern observed.
