title: Thyrotoxic hypokalemic periodic paralysis in a Hispanic male.
abstract: We report a case of a Hispanic male presenting with acute onset of bilateral lower extremity weakness, without any antecedent viral or bacterial illness, dietary changes, infiltrative orbitopathy, diffuse goiter, infiltrative dermopathy, and family history of periodic paralysis, who was later found to have Graves' disease. This demonstrates a rare case of periodic paralysis as the initial presentation of hyperthyroidism. Thyrotoxic hypokalemic periodic paralysis is common in Asian and Hispanic individuals and uncommon in whites and African Americans.
