Autonomic failure in primary amyloidosis.

Amyloidosis is an uncommon plasma cell dyscrasia affecting Multisystem, characterized by deposition of amyloid proteins in extracellular spaces and the tissues. Reported incidence of amyloidosis is 8 cases per million per year. Deposition of amyloid fibrils occurs in peripheral nerves in 20% of the cases in Primary Amyloidosis. Though. polyneuropathy is one of the presenting manifestations in cases of Primary Amyloidosis, pure autonomic failure without involving peripheral nerves is not a documented entity. Here, we present a case of Primary Amyloidosis presenting as Pure Autonomic Failure (Dysautonomia).
