title: Unusual presentations of multiple myeloma.
abstract: Multiple myeloma has many unusual manifestations, which may obscure the true cause and delay proper treatment. Physicians in all specialties should be alert to this possibility, since myeloma may be at the root of such diverse disorders as carpal tunnel syndrome, peripheral neuropathy, solitary lytic bone lesions, hypercalcemia, and hyperviscosity syndrome.
