Diagnosis and management of catecholamine secreting glomus tumors

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 catheterterization studies and for pharmacologic 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.
