 Abstract
 PDF PubReader
Hypothyroid myopathy is observed frequently and the resolution of the clinical manifestations of myopathy following thyroid hormone replacement is well known. However, a specific subtype of hypothyroid myopathy, Hoffmann's syndrome, characterized by increased muscular mass (pseudohypertrophy), proximal muscle weakness, muscle stiffness and cramps, is rarely reported. Herein, we describe a 34-year-old male who presented with proximal muscle weakness and non-pitting edema of the lower extremities. He initially visited the neurology department where he was suspected of having polymyositis. Additional laboratory evaluation revealed profound autoimmune hypothyroidism and elevated muscle enzymes including creatine kinase. The patient was started on levothyroxine treatment and, subsequently, clinical symptoms and biochemical parameters resolved with the treatment. The present case highlights that hypothyroidism should be considered in the differential diagnosis of musculoskeletal symptoms even in the absence of overt manifestations of hypothyroidism. To our knowledge, this is the first case reported in Korea. -

Abstract
PDF
- Pseudohypoparathyroidism is a rare disease that is characterized by target cell resistance to the effects of parathyroid hormone and this disease is classified into various types depending on the phenotypic and biochemical findings. The patients with pseudohypoparathyroidism present with the clinical and biochemical features of hypoparathyroidism, but they have an increased serum level of parathyroid hormone. We experienced a case of pseudohypoparathyroidism in a 24 years old woman who had Graves' disease at that time. She had hypocalcemia, hyperphosphatemia, an elevated serum parathyroid hormone level and a normal urinary basal cyclic AMP(adenosine monophosphate) level. She also had a normal phenotypic appearance. Therefore, she was classified as suffering with pseudohypoparathyroidism type II. The clinical and laboratory abnormalities were improved by calcium supplementation in addition to vitamin D. To the best of our knowledge, this is the first case of pseudohypoparathyroidism combined with Graves' disease in Korea.
