Hair loss after treatment with l-thyroxine in a child with a delayed diagnosis of congenital hypothyroidism

Abstract

"Introduction: In this case report, we aimed to emphasize the rare side effect of L-thyroxine by describing the case who had suffered hair loss after being treated with L-thyroxine. Case report: A 13-year old girl was admitted to our clinic with diffuse hair loss which was stated to start after being treated with L-thyroxine. It was learnt that she had been diagnosed with congenital hypothyroidism since she was 10 years old. We suggest that hair loss following L-thyroxine replacement therapy for congenital hypothyroidism in this case was due to the side-effect of the replacement therapy, which probably resulted in impairment in the balance between the effects of the hormones and growth factors in hair cycle."Biz burada L-tiroksin tedavisi başlandıktan sonra saç dökülmesi şikayeti olan bu olguyla L-tiroksin tedavisinin nadir görülen yan etkisini sunmayı amaçladık.
