[Orthostatic hypotension as a manifestation of malignant lymphoproliferative disease].

An 85-year-old man was admitted with 6-month history of incapacitating orthostatic hypotension. Investigation led to the discovery of sympathetic dysautonomia, sensorimotor neuropathy and malignant lymphoproliferative disease. Several attempts to treat the orthostatic hypotension or the neoplastic disease failed to improve his condition. Orthostatic hypotension precipitated by sympathetic dysautonomia may be an infrequent effect of early malignant lymphoproliferative disease.
