Diagnosis and management of catecholamine secreting glomus tumors.

Abstract
The clinical and diagnostic features of catecholamine secreting glomus tumors are reviewed. Three cases are reported, including the first documented case of a dopamine secreting glomus jugulare tumor. Based on this experience, the authors have outlined the indications for selective venous catherization studies and for pharmocologic blockage in the management of these patients. In addition to routine urinary screening, a high index of clinical suspicion is needed to avoid the complications associated with catecholamine secreting tumors.
