Primary amyloidosis presenting as upper limb multiple mononeuropathies.

ABSTRACT: Peripheral neuropathy in primary (AL) amyloidosis is usually lower-limb predominant, length-dependent, symmetrical, and affects small (pain and autonomic) fibers, as much or more than large fibers. We report a patient with stepwise progressive, multiple upper limb mononeuropathies that were due to nerve biopsy-proven primary amyloidosis (lambda light chain), with no systemic or autonomic features. Recognition that light chain amyloidosis may be the cause of a multiple mononeuropathy pattern adds to the differential diagnosis of this clinical phenotype.
