title: A 32-year-old Man with Normokalemic Thyrotoxic Periodic Paralysis.
abstract: Thyrotoxic Periodic Paralysis (TPP) is a rare and life threatening condition commonly occurring in young Asian males. It is characterized by acute paralytic attacks and hypokalemia in association with thyrotoxicosis. Serum potassium levels may be normal in rare cases of TPP. The diagnosis of normokalemic TPP may be overlooked and/or delayed in most cases. Here, we describe a 32-year-old Iranian man with normokalemic TPP misdiagnosed as somatization disorder with the correct diagnosis made one year after the onset of symptoms.
